Key points of maintenance and Management of Yu Li

Plum is a genus of plum of Rosaceae. It is often grown on the edge of forest, stream or roadside shrub below 800 meters above sea level. Yu plum can not only be used for viewing, but also has high medicinal value, so it is widely cultivated by people. Xiaobian will introduce you to the planting methods and precautions of Yu plum. Interested friends can understand together.

Yu Li

Yu Li prefers sunny, warm and humid environment, strong tree body, strong adaptability, heat and drought tolerance, moisture and smoke tolerance, developed root system and cold tolerance. It can survive the winter safely under-15 ℃ in winter. The soil is not strict, resistant to barren, and can grow in slightly alkaline soil, especially in calcareous soil. It grows well in well-drained, neutral, fertile and loose sandy soil, and can adapt to slightly acidic soil.

I. planting conditions

The transplanting of Yu plum is carried out from defoliation to pre-bud, and the plant needs to bring persistent soil. In North China, it is appropriate to transplant before budding in February and March, and the planting location should be sunny and warm. In the cultivated soil, the humus loam rich in organic matter grows best and the sunshine should be sufficient. When planting, first put the seedlings from the soil next to the cultivation hole, and then put the seedlings into the hole, filling the soil while firmly. The filling should be slightly higher than the cave surface. The planting depth is generally deeper than the height when the seedlings are unearthed, and after the soil sinks, it can be level with the original soil marks. After filling, make an earth Weir around the tree trunk to make it easy to pour root water.

II. Water and fertilizer management

Newly planted trees should be fully fertilized in their burrows before planting. After planting, water the root for the first time, water it for the second time in 7 to 10 days, pour it 3 times in a row, and seal the Weir in time. Water properly during drought. Fertilization was applied once before leaf spreading in early spring and before flowering in April, and 1 kg organic fertilizer was applied per plant. 0.5 kg diammonium phosphate was applied to each plant in autumn.

Third, pruning techniques

In the process of growth, the root sprouting and tillering ability is very strong, which needs to be controlled, and the root tillers should be removed frequently in order to maintain a good and correct plant shape. For young trees, the stem can be fixed when the seedling height is 30 centimeters, starting from 20 centimeters from the ground, choose a main branch every 10 centimeters upward, and select three or four main branches to make them extend to one side. For adult trees, mainly thinning branches, cutting off residual flower branches in time after flowering, and cutting off disease and insect branches, over-dense branches, weak branches and withered branches inside the clump. When the tree is too old, the method of retraction and renewal can be used for pruning. The retracted branches can sprout sturdy branches and can be cultivated into a new crown.

Key points of maintenance and management of flowers overwintering

Key points of maintenance and management of flowers and plants overwintering 1, cold protection in a simple plastic greenhouse with a temperature of not less than 0 ℃, you can put the following ornamental plants without freezing injury, such as Penglai pine, Tianmeng, one-leaf orchid, star anise plate, rhododendron leaf coral, sunflower, kidney fern, palm bamboo, Phyllostachys pubescens, Michelia, firethorn, camellia, cymbidium, cymbidium, Phoenix tail bamboo, phenanthrene, cycad and so on. Ornamental plant species with an overwintering temperature of not less than 5 ℃, such as southern fir, goose palm wood, rubber tree, jasmine, brandy, pearl orchid, pocket coconut, calla lily, spring feather, tortoise back bamboo, Jianlan, Mulan, Belgian rhododendron, triangular flower, cyclamen, primrose, five-colored plum, kumquat, daidai, lemon, loose-tailed anemone, geranium, mulberry, Buddha belly bamboo, etc., can overwinter in a double-layer plastic greenhouse. For the species requiring a winter temperature of not less than 10 ℃, such as variable leaf wood, taro, pepper grass, bamboo taro, rich bamboo, fishtail sunflower, Brazilian iron, rich tree, reticulate grass, pineapple, pink leaf, poinsettia, Cymbidium, Longtuzhu, golden bract, Milan, Phalaenopsis, Cartland, Magnolia, South American iron tree, red (green) gemstone, Oncidium, tiger orchid, etc., in a double-layer greenhouse with good sealing performance. It is also necessary to heat it up properly. in the particularly cold period, from 4: 00 p.m. to 9: 00 the next day, put a grass curtain on the roof of the greenhouse, and then remove it until the temperature gets warmer. For those more hardy potted and bonsai plant species, such as wax plum, plum blossom, begonia, Yingshanhong, pomegranate, hammer elm, sparrow plum, oak, crape myrtle, wisteria, yellow poplar, Luohansong, triangular maple, Cuibai, garden cypress, red cypress, bayberry, Chinese wolfberry, white wax, etc., generally will not be frozen when not less than-10 ℃; in particularly cold weather, cover with plastic film or soft grass to prevent cold.

Whether it is put in the greenhouse, greenhouse, or placed in the bedroom bonsai, potted flowers and foliage, fruit plants, in addition to maintaining the appropriate indoor temperature, but also pay attention to ventilation, can be in the highest temperature of the day around noon to open doors and windows to give ventilation, to prevent the occurrence of fallen leaves, flowers and fruits. In the ventilation, we must also pay attention not to let the cold air directly attack the plant, so as to avoid adverse reactions.

2. Watering most of the potted flowers and bonsai in the greenhouse and in the bedroom to keep the soil moist. If the temperature is too low and too much watering, it is easy to cause rotting roots of the plant. When the temperature rises, the amount of water can be increased and proper foliar spray can be given. For those potted flowers that blossom before and after the Spring Festival, such as camellia, tea plum, Belgian rhododendron, plum blossom, wax plum, melon chrysanthemum, primrose, longevity flower, hyacinth, European daffodil, etc., ornamental fruits such as daidai, lemon, bergamot, tangerine, golden bean, winter coral, rich seeds, Phyllostachys pubescens, etc., should not only keep the potted soil moist, but also spray the leaves to facilitate the expansion of flower buds. It can also increase the freshness of flowers and fruits. For most foliage plants in the shelving room, we should not only keep the basin soil moist, but also spray water on the foliage surface, and always keep the foliage surface clean; for those foliage plant species that are not very cold-resistant, such as Fendai leaf, fruit taro, bamboo taro, leaf-changing wood, silver queen, etc., when the room temperature is close to the minimum temperature they can bear, special attention should be paid to controlling the amount of water to ensure that they can survive the winter safely. The watering time in December should be 3 to 4 hours before and after noon, and the water temperature should be basically consistent with the air temperature and soil temperature, so as to avoid adverse reactions caused by low water temperature.

Newly transplanted flowers and trees outdoors should be checked frequently and replenished in time; for transplanted evergreen trees, foliar spray can be given around noon to prevent leaves from drying and falling off.

3. Fertilization should be stopped for most of the potted flowers and trees, foliage plants and bonsai in the general greenhouse, otherwise it is easy to cause the plant to rot and die.

Most of the green trees and flowers planted on the ground Such as Begonia, Magnolia, Magnolia, Magnol Cryptomeria fortunei, cedar, cypress, Robinia pseudoacacia, elm leaf plum, Yu Li, white silk plum, heather, bauhinia, hibiscus, etc. While ploughing the garden field in December, fertilizers such as cake fertilizer, pig and cow manure, pond mud and septic tank residue can be applied to the periphery of the plant root system, so as to lay a good material foundation for next year's growth and flowering. For potted flower species placed in the room from 10 ℃ to 15 ℃, such as camellia, tea plum, rhododendron, plum blossom, wax plum, golden bract, shrimp flower, pineapple, Ruixiang, melon leaf chrysanthemum, primrose, cyclamen, pedicel begonia, hyacinth, gentleman orchid, tulip, freesia, etc., 1.2% potassium dihydrogen phosphate can be applied to promote the pregnant bud and flowering of the plant.

4. Pruning hedges, green walls and ball shapes that have not been pruned in November. Hedgerows and green walls such as privet, lobular privet, Fa Qing, Populus tomentosa, Shu juniper, four seasons cinnamon, spinulosa heather, etc.; balls such as Chinese wolfberry, bayberry, heather, yellow poplar, Haitong, Admiralty, pyracantha, dragon cypress, juniper, etc., can be fertilized while completing pruning. The ground-planted flowers and trees that have not been pruned in November, such as rose, crape myrtle, palm, red leaf plum, heather, Fatong, plum blossom, wax plum and so on, can be pruned and fertilized around the root system after pruning. For bonsai plant species dominated by shearing, such as hammer elm, sparrow plum, medlar bone, Fujian tea, maple, oak, white wax, fire thorn, June snow, Luohansong, cypress, cypress, begonia, papaya, etc., continue to prune in December to lay a good skeleton for next year's growth; plants that have not changed pots for many years can be combined with pruning to change pots.

5. pest control can reduce the occurrence of diseases and insect pests in grape, begonia, rose, rose, camellia, crape myrtle and other flowers and trees that are prone to diseases and insect pests. At the same time, spray stone sulfur mixture for sterilization and disinfection. For powdery mildew of potted melon-leaf chrysanthemum and Botrytis cinerea of primroses, the former was controlled by triadimefon or thiophanate-methyl in time, and the latter was controlled by thiophanate-methyl. For the species of scale insects that are easy to appear in flowers and trees in the greenhouse, such as hadai, bergamot, cycad, camellia, orchid, etc., you can first wipe them with a dishcloth, and then use pesticides such as quick culling. When there is poor ventilation, aphids often appear on potted plants, such as Magnolia, Milan, daidai, rose, Fujian tea, etc., can be controlled by tobacco water. On the trunk and big branches of flowers and trees such as Haitong, sweet-scented osmanthus, Fatong, camellia, lobular privet, pyracantha, oleander, begonia, Magnolia, bauhinia, gardenia, cedar, heather, crape myrtle, wax plum, etc., there are many kinds of scale insects that often appear on the trunk and big branches of flowers and trees, such as horned wax scale, Japanese tortoise wax scale, red wax scale, shield scale, sagittal scale, pink scale, velvet scale, etc., at this time, spray and kill with high concentration of pesticides such as quinathulfan, quinathulene, buprofezin and other pesticides. Drug damage is rarely caused.

6. Composting fertilizer in order to raise seedlings and prepare culture soil next year, we can use winter leisure time to pour rapeseed cake, bean cake and tea seed cake into water tanks and pools and add water for sealed fermentation. Dry withered grass, fallen leaves, shrubs, branches, etc., are piled up in layers with the garden soil, ignited and burned to form burning soil, which is a good covering soil for sowing and raising seedlings next year. Compost, pond mud, chicken droppings and pigeon manure were mixed with garden soil and sealed fermentation, which can be used for topdressing seedlings and preparing culture soil in the coming year.

7. make use of the free time in winter to find an open space or pile up as much culture soil as possible in the shade of trees, so as to meet the need of changing pots and potting grass flowers next spring. Generally, there are 4 parts of garden soil, 2 parts of rotten leaf soil (or 2 parts of alpine humus soil), 1 part of fine sand, 1 part of piled sawdust, tobacco dust or bran ash, plus about 5% retted cake fertilizer and 2% to 3% compound fertilizer. Among them, garden soil and rotten leaf soil should be screened, gravel, tree roots and other sundries should be sifted, fully mixed, covered with plastic film, and can also be stacked indoors after 3 to 4 months. It can be used for changing pots or potting grass flowers.

8. For the garden used for sowing, cutting and planting seedlings next year, ploughing can be carried out in December; for the garden for sowing and planting seedlings, cake manure, barnyard manure, pond mud, etc., can be applied before replanting; do not make beds for the time being, go through winter freezing, and then dig ditches to make beds in the early spring of next year, which can greatly reduce the cost of seedling management and reduce the occurrence of diseases and insect pests. The ornamental plants suitable for bonsai modeling in December are: Luohan pine, Luohanbai, garden cypress, cypress, velvet cypress, Platycladus orientalis, Sabina vulgaris, black pine, five-needle pine, red pine, bayberry, wolfbone, holly, weeping spear, ginkgo, June snow, broom elm, finch, triangular maple, wax petal flower, Tamarix, pedicel begonia, weeping silk begonia, papaya begonia, melon seed yellow poplar, pearl yellow poplar, wisteria, purple myrtle, banyan, banyan, Fujian tea, white wax, oak and so on. For bonsai plants fixed with brown wire (rope) or wire, if it has been fixed for one year, or obvious constriction marks are found on the stem or branch, the original ligature should be removed and the wire or brown rope should be used for hanging traction. For plum piles, Luohansong, begonia, ginkgo, cypress, crape myrtle, etc., after some necessary pruning and plastic surgery, choose a good pot for planting and strengthen management, so that they can be used in public places or rooms for display in the coming year.

In winter, we must carefully manage some shallow landscape bonsai and tree stump bonsai: first, to prevent the roots of plants from frostbite in the basin soil; second, to prevent the disintegration of artificial cemented rocks caused by freezing; and third, to prevent plants planted on rockery from freezing or drying to death. It can be placed in an ice-free place and watered regularly so that it can survive the winter safely. Key points of flower management in June Weather characteristics of June: from time to June, the temperature rose further. The Yangtze-Huaihe River Basin has entered the Meiyu season, entering the plum on June 12 and coming out on July 7 this year, when the evenly matched cold and warm air met in the region, causing frequent frontal or cyclone activities. June is the season with the largest number of Rain Water of the year, with long periods of continuous rainfall. Special care should be taken for some dormant or semi-dormant flowers and most bonsai in summer, so as not to cause rotten roots due to Rain Water, or plant growth due to lack of light, disturbing the shape or affecting the normal flowering and fruiting of ornamental plants.

The main contents of raising flowers from south to north in June are as follows:

I. Flower culture

1. Sowing seeds

The flowers and trees that can be sown in June are: primrose, lotus seed, cycad, loquat, wax plum and so on. For Chimonanthus praecox, when the pot-shaped fruit sac on the fruiting mother tree changes from green to yellow, and then from yellow to brown, the internal seeds are brown; peel off the fruit sacs in time, remove the seeds, soak them in cold water for 24 to 36 hours, wait for the seeds to absorb enough water to expand, and then bury them in clean wet sand to sprout. After about 2 weeks, the seeds can be split and sown in a ditch. The thickness of the covered soil is generally 2 cm to 3 cm, covered with straw to moisturize. After the cotyledons of most seeds are unearthed, remove the grass for 2 to 3 times and build a shed for shade in time.

two。 Cuttage

In summer, the temperature and humidity are high, and the cambium in the branches of flowers and trees is active, which is the best time for cutting and cultivating flowers and trees. There are two kinds of flowers and trees suitable for softwood cutting in summer. One is the species of hardwood cuttings that are difficult or slow to root, such as sweet-scented osmanthus, camellia, Michelia mollissima, wolfberry, holly, clove, purple magnolia, tapestry, snowball, Qionghua, coral tree, paulownia,

Belgian rhododendron, Buddha belly bamboo (taking root with gas), rubber tree, metasequoia, pond fir, Cryptomeria fortunei, etc.; the other is the species that are easier to take root, such as yellow poplar, rose, pyracantha, golden bell, welcome spring, Jasmine, June snow, pomegranate, hibiscus, goldfinch, jasmine, pearl orchid, dragon leaf bead, five-colored plum, Diitang, leaf flower, bergamot, lemon, Pinus elliottii, Phyllostachys pubescens, Lingxiao, red cinnamon,

Honeysuckle, Fusang, plantain, hypericum, golden plum, golden willow, dragon claw willow, banyan tree, Brazilian iron, cinnabar root, fragrance, variable leaf wood, Linnaeus, mountain plum blossom, crape myrtle, sea immortal, brocade flower, hemp leaf hydrangea, peach coral, goose palm firewood, ten meritorious categories, star anise plate, snow spray, eight immortal flowers, poinsettia, etc. It also includes a large number of other grass flowers, such as five-clawed golden dragon and ground.

Brocade, golden lotus, Qin Finch, thousand autumn tea, perfume grass, umbrella grass, geranium, colored leaf grass, begonia, tricolor pansy, thousand-day red, hundred-day red, peacock grass, marigold, sulfur chrysanthemum and so on.

Take the fully closed moisturizing cuttings of camellia and sweet-scented osmanthus as an example: the cutting time is from early June to mid-July, when the twigs of sweet-scented osmanthus and sweet-scented osmanthus are semi-lignified, and the substrate can be yellow soil, sandy soil or vermiculite. Cuttings are new shoots of the year, 10 cm to 15 cm long, leaving only 2 to 3 leaves at the end. Dip the lower incision with 500mg / kg 1#ABT rooting powder or naphthalene acetic acid solution for 10 seconds, dry slightly and insert it into the seedbed. The depth of the cuttings is 1x2 to 2x3, and the row spacing is 2cm × 8cm. After pouring water, set up a bamboo bow on the seedbed, then cover it with plastic film, press it tightly with mud around, shade the light in a double-layer shade, keep the bed moist, control the temperature in the film at about 30 ℃, and keep the humidity above 90%. Generally, a large number of cuttings can take root after one month.

3. Grafting

Lean on, take potted seedlings of Chimonanthus praecox as rootstock, lean on excellent varieties of Chimonanthus mume, use potted Magnolia and Magnolia seedlings as rootstocks to connect Magnolia, Michelia and so on. Bud grafting, using wild rose seedlings as rootstocks, grafting and breeding excellent rose varieties; using apricot, peach, plum and other annual seedlings as rootstocks, budding breeding Birthday Bun with Bean Paste Filling, green peach, purple leaf plum, red leaf peach, Yu plum, plum blossom, etc.; using 1-2-year-old maple seedlings as rootstocks, red maple, feather maple, red maple and so on. Branch grafting, Camellia oleifera, Camellia oleifera or Camellia oleifera seedlings as rootstocks, Camellia oleifera and Camellia oleifera as rootstocks, "Purple Butterfly" and "Jade Butterfly" in rhododendron as rootstock, split or abdominal grafting of Belgian rhododendron or western rhododendron.

4. Pressing strip

The feasible species of flowers and trees for strip culture in June are: rhododendron, honeysuckle, eight immortals, snowball, Qionghua, brocade, oleander, sweet-scented osmanthus, camellia, plum, wax plum, clove, gardenia, red maple, Milan, pearl orchid, jasmine, magnolia and so on.

5. Ramet

The flower species that can be cultivated in June are: kidney fern, calla lily (after anthesis), Phyllostachys pubescens, dry umbrella grass, purple back evergreen, pineapple, 12 volumes, one leaf orchid, calamus, Ophiopogon, and so on.

II. Seed harvesting and transplanting

1. Harvest seeds

The grass flower seeds that can be harvested in June are: carnation, cornflower, goldfish grass, dwarf snow wheel, high snow wheel, hollyhock, mallow, primrose, bungee, Zhu Dinghong (sown with picking) and so on.

Flower and tree seeds that can be harvested in June: after harvest, if the nursery conditions are not allowed, the detached seeds can also be dried and sown until next spring, which will not affect their germination rate; peaches and apricots should be sowed as they are picked, or the seeds should be stored in the crack to germinate and then sow. The sweet-scented osmanthus seeds harvested in June were removed from the fleshy pericarp and washed, stored in wet sand to promote the post-ripening of the embryo, and then sowed in the nursery when they germinated.

two。 Transplanting, planting and potting

In June, a considerable number of grass flowers need to be transplanted and planted or put on the pot. they are: evening primrose, drunken butterfly, impatiens, guinea impatiens, primroses, ornamental peppers, winter corals, red tobacco, petunia, marigold, peacock grass, hundred-day grass, thousand-day red, a string of red, dragon mouth flower, ground skin, sulfur chrysanthemum, cockscomb, red-green grass and so on.

In summer, some large flowers and trees are no longer transplanted, so as not to affect their survival rate and growth after transplanting. But for some small flowering shrubs, such as star anise, broad leaves, ten meritorious works, hypericum, gardenia, Phnom Penh privet, red leaf Berberis, boxwood, under special circumstances, it is not impossible to transplant with a ball. as the old saying goes, "Don't call a tree to know all the time."

However, the management of water spraying and sunshade should be strengthened after transplanting.

III. Flower management

1. Watering

Watering potted flowers in June should pay attention to the following aspects: first, watering time, 10:00 or 5pm is better, usually watering once a day; second, watering temperature, watering water should be kept basically consistent with basin soil temperature, if the difference between water temperature and soil temperature is too large, it will cause potted flower roots and leaves to be stimulated and then affect their growth. Third, the combination of watering and spraying, when it has not rained for several days, in addition to watering the basin, it is also necessary to spray water around the leaves and potted flowers in order to improve the humidity of the local space. If there is a continuous cloudy day, it depends on the dry and wet condition of the basin soil to decide whether to give watering and spraying.

A species of flower that enters semi-dormancy or dormancy in summer. Semi-dormant people such as: safflower sorrel, geranium, inverted golden bell, magnolia, calla lily, begonia, etc., when the temperature is more than 30 ℃, because their growth activity is very weak, the metabolic level is low, it is necessary to reduce watering and keep the basin soil moist; deep dormant species such as cyclamen, Lycoris (class), buttercup, lotus

Orchid peony and so on, under high temperature, the aboveground stems and leaves withered, the underground nutrient fibrous roots withered, and the underground stems or tubers spent the summer dormant in the soil, so they must stop watering and move to a cool place to keep the basin soil from being too dry.

If there is continuous rain, check the potted flowers thoroughly after the rain stops and find that there is stagnant water in the pot. pour them away as soon as possible, and loosen the soil after the pots are dry, so as not to cause rotten roots, or knock down the potted flowers before the heavy rain, and then straighten the potted flowers after the rain stops.

two。 Fertilizer application

For thriving species, such as tortoise-backed bamboo, hanging orchid, taro, bamboo, kidney fern, spring feather, iron tree, one-leaf orchid, hulk, red (green) gem, green emperor, green queen, rubber tree, red palm, red-backed cinnamon, brown bamboo, southern sequoia, Brazilian iron, rosewood, wax plum, rose, Magnolia, Milan, jasmine, pearl orchid, plum, camellia, tea plum, Ruixiang, du

Cuckoo, cinnamon, five-color plum, dragon spit bead, shrimp flower, dai dai, lemon, kumquat, pomegranate, crape myrtle, firethorn, etc., can be retted once every other half-month thin cake fertilizer, the species that are blooming, but also apply an appropriate amount of phosphorus and potassium fertilizer to meet its growth and flowering, fruit hanging needs.

For those flower species that are dormant or semi-dormant, fertilization must be stopped; especially for those succulent flower species, such as jade leaves, crab claw orchid, crystal cactus, cactus pen, squirrel tail, pine chrysanthemum, leopard skin flower, sedum, when the temperature reaches above 35 ℃, stop fertilization to avoid decay.

3. Pruning, picking buds

⑴ pruning Lang elm, Finch plum, Luo Hansong, Fujian tea, real cypress, juniper, bayberry, round cypress, wolfberry, holly, triangular maple snow willow, Tamarix, firethorn and other kinds of vigorous growth, the branches that affect the shape should be pruned or shrunk as soon as possible, so that the plant can maintain a hierarchical and good appearance, and can promote it to draw more short branches, send more new buds, and form a perfect shape as soon as possible.

When ⑵ picks buds from Milan, jasmine, magnolia, rose and other flowers, the abortive stems of the remnants should be removed in time, and the branches that have flowered should be properly shrunk so as to promote the lower side branches or flower buds to bloom again. In order to promote the flowers and trees such as Magnolia, daidai, rhododendron, camellia, wax plum, plum blossom and begonia to form a good plant shape, in the same year or in the coming year, more pregnant flowers, more blossoms and good flowers, those branches that are too prosperous should be topped and budded to inhibit the growth of the main and lateral shoots and promote the germination of lateral buds.

4. Shade

In June, those flowers and trees that like shade or semi-shade must be moved to the shade to prevent the sun from causing damage to the plants. Such as Hosta, purple calyx, asparagus, camellia, tea plum, rhododendron, orchid, orchid, palm bamboo, rubber tree, fern, forest taro, synthetic taro, pink daiye, spring feather, green apple, bean green, hulk, red (green) gemstone, green emperor, red

Queen, Pukui, Ruixiang, Euphorbia, Cymbidium, and so on. Flower species that like light must be given sufficient light, such as pomegranate, wisteria, Firethorn, crape myrtle, jasmine, June snow, cycad, cypress, peach blossom, plum blossom, wax plum, elm, Fujian tea, triangular maple, sparrow plum, wolfberry bone, holly, water bayberry, oak, black pine, brocade pine, Bailan, Milan, rose, ten meritorious works, grapes and so on. Luohansong, tiger thorn, bamboo, Buddha belly bamboo, Guanyin bamboo, five-needle pine, bamboo and cypress, etc., can be given appropriate shade.

5. Prevention and control of diseases and pests

⑴ cypress, cypress, elm, papaya, pyracantha, Luohansong and begonia are easy to be harmed by longicorn beetles, so poison label should be used in time to prevent and cure them.

⑵ rose, etc., are prone to powdery mildew and brown spot in the rainy season, so it is necessary to spray Bordeaux solution as soon as possible.

⑶ Magnolia, plum blossom and wax plum are easy to be harmed by aphids, so it is necessary to choose appropriate pesticides as soon as possible.

The leaves of ⑷ orchids are easy to be infected with anthracnose, so carbendazim and other fungicides should be sprayed as soon as possible.

⑸ daidai, lemon, kumquat, bergamot, etc., tender leaves are easy to be eaten by citrus butterfly larvae, can be sprayed with contact agents, stomach poisons and other pesticides to kill.

Fourth, bonsai modeling

The plant species that can be modeled in June are mainly woody ornamental plants with strong adaptability and resistance to prickling, and they must be pots or ground-planted plants in early spring. They are: Luo Hansong, Yingchun, Elaeagnus angustifolia, Huashan pine, Cuibai, round cypress, medlar bone, holly, Chinese wolfberry, five-needle pine, weeping begonia, Xifu begonia, plum blossom, green peach, triangular maple, June snow, black pine,

Melon seeds and yellow poplar, hammer elm, Tamarix, bayberry, true cypress, ginkgo, snow willow, firethorn and so on. June modeling must be careful, light and slow, must not be too hasty, too hard.

Solar terms in mid-June: Grain in Beard on June 5; the Summer Solstice on June 21.
