The Main Points of Sowing and Propagation of Sapphire

Artemisia frutescens is an annual or biennial herbaceous flower with bright colors. Now more and more flower friends plant it in pots. The sowing method is usually used for the reproduction of Rabdosia mandshurica. The editor will introduce to you the sowing method and the key points of management after sowing.

Artemisia mandshurica

First, sowing and reproduction

It is propagated by sowing method, and sown in autumn in areas where the soil is not frozen in winter. Seedlings were raised indoors in the northern region in early spring and emerged in about 7 days under the condition of 15-20 ℃. Get up the seedling and put it on the pot in time before the real leaf is developed, and after no frost, take off the pot and plant it with soil (do not hurt the root, otherwise it is not easy to restore growth. Even death); it can also be broadcast live in the open before the land freezes. Under the protection of wind barrier, the seedlings were unearthed the following year. Adequate water and nutrients should be provided at the seedling stage. To make it grow strong.

2. Management after sowing

After sowing in autumn, when you encounter a cold wave and low temperature, you can wrap the flowerpot with plastic film to keep warm and wet; after the seedlings are unearthed, the film should be opened in time, and before 9:30 every morning, or let the seedlings receive the sun after 3:30 in the afternoon, otherwise the seedlings will grow very weakly. After most of the seeds come out, they need to plant seedlings properly: pull out the diseased and unhealthy seedlings, so that the seedlings left behind have a certain space between each other; when most of the seedlings grow 3 or more leaves, they can be transplanted into the pot.

Morphological characteristics and ecological habits of Rabdosia mandshurica

Artemisia mandshurica is a perennial herb, which is often cultivated for one or two years. Strong cold resistance, like cold and dry climate, not resistant to wet and hot, hot summer in a semi-dormant state, often withered, and then germinated after autumn. Originally from California, USA.

It is a good material for flower belt, flower diameter and pot planting, and can also be used for lawn cluster planting.

Hualing Prairie is produced in California, USA. More cold-resistant, like cold, cool and dry climate, not easy to wet and hot, should be loose and fertile, good drainage, upper layer deep sandy loam, but also barren soil. Perennial herbaceous flowers are often cultivated in 2012.

Artemisia mandshurica is the state flower of California, also known as California poppy, and it is also known as ginseng and Jinying flower.

Flowering lasts from spring to early summer, with flowers blooming in sunny days and closed in cloudy or evening days. The colors are scarlet, rose, milky white, orange, yellowish and so on. Its valve has four, the outer edge shows wave wrinkle.

Most wild turquoise plants have yellowish, orange or cream flowers. When you face the almost boundless wilderness blooming like a sea of flowers and grasses, you can't help but praise it, and your heart will gladly rise with a beautiful poetic feeling.

The stems and leaves of Rabdosia mandshurica are tender green, with a little gray, and the bright flowers and colors are very lovely. At the turn of spring and summer, there are often flowers and grasses planted in front of other people's houses, and some are planted into flower belts, adding vitality to the house.

The flowers of the same genus as this species include tufted flowers and curved-leaf flowers.

Seeds globose, 1-1.5 mm in diam., with conspicuous reticulation.

The florescence is from April to August and the fruiting period is from June to September.

Ecological habits of Rabdosia mandshurica

Artemisia mandshurica grows in grasslands and open areas at elevations of 0 to 2000 meters.

More cold-resistant, like cold, cool and dry climate, not easy to wet and hot, should be loose and fertile, good drainage, upper layer deep sandy loam, but also barren soil.

Artemisia mandshurica has strong cold tolerance, likes cold and dry climate, is not resistant to damp and hot, is in a semi-dormant state in hot summer, often dies, and germinates again after autumn. Belongs to the fleshy straight root system, must the deep loose soil, the request drainage is good, the big seedling should not transplant. Can sow and reproduce itself.

Key points of reproduction and cultivation: Rabdosia angustifolia is taproot, seed reproduction, suitable for direct seeding, autumn sowing (sowing or strip sowing) in areas where the soil is not frozen in winter.

In the northern region, it is generally sown in the open field in late October, wind barriers are set up in early November, overwintering in the open field, and transplanted in spring. Can also be in the next spring direct seeding flower bed thawing soil, plant row spacing l5*2Ocm, hole sowing multi-grain, inter-seedling, summer flowering.

Attention should be paid to maintaining sufficient water and nutrients in the seedling stage. 30 days after flowering, the germinated fruit is easy to crack and should be harvested in the early morning. Each watering should not be too large, fertilization can be appropriate.

The propagation mode of Rabdosia mandshurica

Sowing and reproduction

It is propagated by sowing method, and sown in autumn in areas where the soil is not frozen in winter. Seedlings were raised indoors in the northern region in early spring and emerged in about 7 days under the condition of 15-20 ℃. Get up the seedling and put it on the pot in time before the real leaf is developed, and after no frost, take off the pot and plant it with soil (do not hurt the root, otherwise it is not easy to restore growth. Even death); it can also be broadcast live in the open before the land freezes. Under the protection of wind barrier, the seedlings were unearthed the following year. Adequate water and nutrients should be provided at the seedling stage. To make it grow strong.

Management after sowing

After sowing in autumn, when you encounter a cold wave and low temperature, you can wrap the flowerpot with plastic film to keep warm and wet; after the seedlings are unearthed, the film should be opened in time, and before 9:30 every morning, or let the seedlings receive the sun after 3:30 in the afternoon, otherwise the seedlings will grow very weakly. After most of the seeds come out, they need to plant seedlings properly: pull out the diseased and unhealthy seedlings, so that the seedlings left behind have a certain space between each other; when most of the seedlings grow 3 or more leaves, they can be transplanted into the pot.

Cuttage propagation

Magnolia cuttings substrate: is used for cutting nutrition soil or river sand, peat soil and other materials. Due to the limited conditions, it is difficult to get an ideal cutting substrate, so it is recommended to use the prepared and sterilized cutting substrate provided by this station; medium and coarse river sand is also fine, but rinse with clean water several times before use. Do not use sea sand and river sand in saline-alkali areas, they are not suitable for the growth of flowers and plants.

Selection of cutting branches: the branches used for cutting are called cuttings. Usually combined with the heart-picking work, the sturdy, disease-free top tip is taken as a cuttage, and the top tip is cut directly.

The language of Flower Lingcao

The flower words and symbols of Hua Lingcao represent the meaning: promise me that you will not refuse me.

It is a good material for flower belt, flower diameter and potted plant, and can also be used for lawn cluster planting.

Hualing Prairie is the state flower of California, USA.

Lingcao grass is more hardy, like the sun, flowers open in the sun, cloudy days and closed at night.

In the northern region, it is generally sown in the open field in late October, wind barriers are set up in early November, overwintering in the open field, and transplanted in spring. Can also be in the next spring direct seeding flower bed thawing soil, plant row spacing l5*2Ocm, hole sowing multi-grain, inter-seedling, summer flowering. Attention should be paid to maintaining sufficient water and nutrients in the seedling stage. 30 days after flowering, the germinated fruit is easy to crack and should be harvested in the early morning. Each watering should not be too large, fertilization can be appropriate. The cultivation techniques of ① should pay attention to the fleshy root, monotonous and afraid of waterlogging. In the rainy season, the ground should pay attention to timely drainage, potted plants should be properly watered, should be dry rather than wet, to avoid black erosion of the root neck. ② because Rabdosia frutescens is a taproot plant with long main roots and is not resistant to transplanting, so it is appropriate to direct seeding seeds in the pot. ③ plants sown in spring blossom in summer, but their growth and flowering are usually not as good as those sown in autumn. Therefore, sowing should be carried out from August to September, and the suitable temperature for germination is 15 ℃ 20 min. If the sprouting is irregular and the emergence of seedlings is dense, appropriate seedlings are needed. The planting distance is 20ml and 30cm, the planting site should be high and dry, and the drainage should be good. During the growing period, we should pay attention to loosening the soil and weeding, and cold prevention measures should be taken to spend the winter in the open field. After the ④ pericarp turns yellow, it should be harvested in the early morning, otherwise the capsule will crack on its own, resulting in scattered seeds. [3] after a period of time to restore the pot of sowing seedlings in autumn, it is necessary to quickly keep up with the management of fertilizer and water. Fertilizer and water management circulates in the order of "Huabao"-- "Huabao"-- clear water-- "Huabao"-- "Huabao"-- clear water-- with an interval of about 1-3 days, and shorter intervals in winter and spring during sunny days or high temperatures. the interval period is longer or not watered during rainy days or low temperatures. Although it continues to grow in winter, the low temperature will slow down its growth rate, require little fertilizer and water, and even control fertilizer and water. Fertilizer and water management according to the "Huabao"-clear water-clear water-"Huabao"-clear water-clear water cycle, the interval period is about 4-7 days, and the watering time is arranged as far as possible when the temperature is high at noon on a sunny day. After the temperature rises in spring, the growth recovers rapidly, and gradually enters the flower bud differentiation stage and flowering stage, which requires a lot of fertilizer and water. Fertilizer and water management circulates in the order of "Huabao"-- clear water-- "Huabao"-- clear water-- with an interval of about 2-4 days, shorter intervals in sunny days or high temperatures, longer intervals or no watering in rainy days or low temperatures. After entering the fruiting stage, stop the supply of fertilizer. Pruning in the flowering process, the residual flowers with three leaves cut off, can prolong the flowering period. Like other grass flowers, fertilizer and water management requires more fertilizer and water, but is most afraid of random fertilization, concentrated fertilizer and partial application of nitrogen, phosphorus and potassium fertilizer, and requires to follow the two fertilization principles of "frequent application of light fertilizer, less and more times, complete nutrition" and "dry and wet, dry and thoroughly, not dry and irrigated". And after fertilization, leaves and flowers should be kept dry at night. The sowing method is used to propagate, and autumn sowing is carried out in the areas where the soil is not frozen in winter. Seedlings were raised indoors in the northern region in early spring and emerged in about 7 days under the condition of 15-20 ℃. Get up the seedling and put it on the pot in time before the real leaf is developed, and after no frost, take off the pot and plant it with soil (do not hurt the root, otherwise it is not easy to restore growth. Even death); it can also be broadcast live in the open before the land freezes. Under the protection of wind barrier, the seedlings were unearthed the following year. Adequate water and nutrients should be provided at the seedling stage. To make it grow strong. [2] Management after sowing after sowing in autumn, when you encounter a cold wave and low temperature, you can wrap the flowerpot with plastic film to keep warm and moisture. after the seedlings are unearthed, the film should be opened in time and before 9:30 every morning. or let the seedlings receive the sun after 3:30 in the afternoon, otherwise the seedlings will grow very weakly. After most of the seeds come out, they need to plant seedlings properly: pull out the diseased and unhealthy seedlings, so that the seedlings left behind have a certain space between each other; when most of the seedlings grow 3 or more leaves, they can be transplanted into the pot. Cutting propagation flower turbot cutting substrate: is used for cutting nutrient soil or river sand, peat soil and other materials. Due to the limited conditions, it is difficult to get an ideal cutting substrate, so it is recommended to use the prepared and sterilized cutting substrate provided by this station; medium and coarse river sand is also fine, but rinse with clean water several times before use. Do not use sea sand and river sand in saline-alkali areas, they are not suitable for the growth of flowers and plants. Selection of cutting branches: the branches used for cutting are called cuttings. Usually combined with the heart-picking work, the sturdy, disease-free top tip is taken as a cuttage, and the top tip is cut directly. The optimum temperature for rooting of cuttings after cuttage was 18 ℃ ~ 25 ℃, which was lower than 18 ℃, the rooting of cuttings was difficult and slow, when the temperature was higher than 25 ℃, the cuttings were susceptible to bacterial infection and rot, and the higher the temperature was, the greater the proportion of rotting was. When there is a low temperature after cutting, the heat preservation measure is mainly to wrap the flowerpot or container used for cutting with thin film; when the temperature is too high after cutting, the cooling measure is mainly to shade the cuttings, to cover 50-80% of the sun, and at the same time, spray the cuttings 3-5 times a day, with more times of spraying when the temperature is higher in sunny days, lower temperatures and higher temperatures in rainy days, but less or no spraying times. Humidity after cutting, the relative humidity of the air must be kept at 750.85%. You can increase the humidity by spraying the cuttings 1-3 times a day, the higher the temperature in sunny days, the more times you spray, and the lower the temperature in cloudy and rainy days, the less or no spraying. But with excessive spraying, cuttings are easy to be infected by bacteria and rot, because many kinds of bacteria exist in the water. Light cutting propagation is inseparable from sunlight, but the stronger the light is, the higher the temperature in the cuttings is, the more exuberant the transpiration of cuttings is, and the more water is consumed, which is not conducive to the survival of cuttings. Therefore, after cutting, the sun must be shaded by 50% to 80%, and then gradually removed after the root system grows: remove the sunscreen at 4:00 every sunny day, and cover it before 9:00 the next day. Potted or transplanted: when the seedlings are potted, put a coarse-grained matrix or ceramsite 2cm thick at the bottom of the pot as a filter layer, sprinkle a layer of fully mature organic fertilizer as base fertilizer with a thickness of about 1cm, then cover it with a substrate, about 1cm thick, and then put in the plant to separate the fertilizer from the root system to avoid root burning. The substrate used in the pot can choose one of the following vegetable garden soil slag = 3RU 1; or garden soil: medium coarse river sand: sawdust (slag) = 4RU 1VR 2; or one of paddy soil, pond mud, rotten leaf soil. Or peat + perlite + ceramsite = 2 + 2 + 1 or vegetable garden soil + slag = 3 + 1 or peat + slag + ceramsite = 2 + 2 + 1 or sawdust + vermiculite + medium coarse river sand = 2 + 2 + 1, pour once after the basin and keep in a shady environment for a week. When transplanting the seedlings, first dig the planting hole, sprinkle a layer of organic fertilizer at the bottom of the planting hole as the base fertilizer (base fertilizer), the thickness is about 46.6 cm, and then cover a layer of soil and put it into the seedlings to separate the fertilizer from the roots and avoid burning roots. After putting it into the seedling, backfill the soil, cover the root system, and trample the soil with your feet and water it once. Coring is usually carried out twice before flowering to promote the germination of more flowering branches: one to two weeks after potting, or when the seedling is 6-10 cm tall and has more than six leaves, remove the tip and retain the lower 3-4 leaves to promote branching. After 3-5 weeks of the first coring, or when the lateral branch grows to 6-8 cm long, the second coring is performed, that is, the top tip of the lateral branch is removed and the 4 leaves under the lateral branch are retained. After two coring, the plant type will be more ideal and the number of flowering will be more. Prevention and control of diseases of Chrysanthemum morifolium L. Under the condition of high temperature and high humidity, or too much fertilization, can lead to the occurrence of diseases and insect pests. When diseased plants are found, in addition to timely drug prevention and treatment, diseased plants should also be removed for burning or deep burial treatment. At the same time, pay attention to field hygiene. The distribution area of Hualing grassland is native to California. It is widely introduced as garden ornamental plants in China.
