How to raise the bonsai of Fructus mandshurica, the breeding methods and points for attention / sufficient light

Lespedeza is a kind of flower plant native to Heilongjiang Province of our country, which has high ornamental value, but it is not easy to raise it well. There are many places we need to pay attention to. How to raise Lespedeza bonsai? What are the cultivation methods and precautions of Lespedeza? The following small series takes everyone to understand.

1. How to cultivate Lespedeza bonsai and understand its habits

If you want to know how to raise Lespedeza potted plants, first of all, we need to understand its growth habits, whether it is cultivated outdoors or indoors, but its adaptability to the new environment is not very strong, so if we are long-term indoor or outdoor cultivation, do not easily change the environment, otherwise it will affect its growth.

Second, the cultivation methods and precautions of Lespedeza

1. humus soil

If Lespedeza bicolor can thrive, it needs to grow in suitable soil. This kind of plant prefers loose and fertile humus soil. This kind of soil has good drainage and permeability, and is rich in nutrients, which can make the plant absorb nutrients better, and it is not easy to accumulate water.

2. Fertilization, not much demand

Lespedeza this kind of plant for fertilizer demand is not high, so we do not need too much fertilizer when breeding it, we only need to plant in the soil when applying the right amount of base fertilizer can, if the soil is rich in nutrients, growth period is not required to fertilize it, wait until its flowering can be supplemented once.

3. Moisture, keep soil slightly moist

Lespedeza this plant is more resistant to drought, not waterlogging, so we should not be too much watering in the process of breeding it, keep the soil slightly wet, in the summer when the temperature is higher, we can increase the watering frequency appropriately, in winter, we should water less, in short, we keep it watered "do not water, water is watered thoroughly" principle can be.

4. Light, shade in summer

Lespedeza is a light-loving plant, so we have to keep it in sufficient light when breeding it, so that it can better carry out photosynthesis, so that the plant will grow better. However, in summer when the light is strong, we still need appropriate shade, so as not to receive long-term direct sunlight and cause the plant to wither.

5. Diseases and pests should be treated in time

In the process of breeding Lespedeza, if we are not careful enough, it is easy for pests and diseases to enter, this kind of problem is very harmful to plants, so we must deal with it in time after discovery, as for specific treatment methods, you can refer to Lespedeza pest control article, which has a detailed introduction.

The roof greening plant configuration must see these five points

Roof greening is of great significance in urban greening. It has a wide development space and is also a key project for us to pursue high-end greening in the future. Its decoration and plant configuration cannot be underestimated.

plant decoration

Can use cornice, two canopy slope roof, flat roof, trapezoidal roof for decoration. According to different planting forms, potted plants for flower viewing, leaf viewing and fruit viewing are commonly used, such as potted rose, oleander, firethorn, osmanthus flower, colorful leaf taro, etc., hollow bricks can also be used to make various flower troughs 25 cm high, lined with thick plastic film, up to the edge of the trough, with drainage holes left at the bottom, filled with culture medium, planting various plants and flowers, such as a string of red, balsam, aster, zinnia, petunia, etc., and planting various woody flowers. Can also be used barrels or large potted woody flowers embellishment, in the case of not affecting the building load, can also set up shade shed planting grapes, wisteria, Lingxiao, costus and other vines. On the wall of the platform, the fence wall can be planted with creeper, ivy, etc.

According to the roof garden bearing capacity and planting form of coordination and change, can make the roof garden produce different characteristics. Flat roofs with limited bearing capacity can be planted with ground covers or other dwarf flowering shrubs, such as sedum sarmentosum, semi-branch lotus and climbing vines such as creeper, wisteria vine, five-leaf broccoli, Chinese cabbage and Chinese knotweed, etc. directly covering the roof to form green carpets. For the roof with better conditions, it can be designed as an open garden, referring to the garden-style layout, making it natural, regular and mixed. But the general principle is to plant decoration, appropriate stacking rockery, stone boat, scaffolding, flower wall and so on to form a modern roof garden. We should pay special attention to the roof garden in the city, should build less or not to build pavilions, platforms, buildings, pavilions and other building facilities, and pay attention to the ecological effects of plants.

One very important consideration in designing a roof garden is the limited capacity. Roof gardens are often relatively high, so the wind is also relatively large, in addition to thin roof soil layer, long lighting time, large temperature difference between day and night, humidity is small, you can choose some light-loving, cold-resistant, heat-resistant, drought-resistant, barren, vigorous flowers and trees. It is best to use shrubs, bonsai, turf and other plants, in short, the use of more fibrous roots of tree species, horizontal roots developed, can adapt to the requirements of shallow soil layer, as far as possible to use tall trees with main roots, if you want to use large specifications Qiao, planting position should be designed in the bearing column and the main wall position, not on the roof board. It should also be noted that the planting soil of the roof is light, and the wind resistance of tall trees is obviously weaker than that of the ground. Therefore, reinforcement measures should be taken.

The thickness of soil layer shall be kept to a minimum. General turf and other low ground cover plants, cultivated soil depth of about 16 cm; shrub depth of 40 cm to 50 cm; tree depth of 90 cm to 100 cm. Special attention should be paid to the roof of high-rise buildings as far as possible not to plant trees higher than 5 meters, the wind is easy to fall.

Rooftop trees are less, shrubs and herbs are more, so in the design, especially to achieve high and low density of trees and flowers, harmonious and reasonable color collocation.

plant disposition

Roof garden design must take full account of the natural conditions, such as strong structure, bearing capacity and water and drainage facilities.

1. Select drought-resistant and cold-resistant dwarf shrubs and herbs.

Because the roof garden summer temperature is high, the wind is strong, the soil moisture performance is poor, winter is poor insulation, so should choose drought resistance, cold resistance strong plants, taking into account the roof of the special geographical environment and load-bearing requirements, should pay attention to the selection of short shrubs and herbs, in order to facilitate the transportation, planting and management of plants. Therefore, generally should choose positive, drought, cold shallow root plants, but also must belong to low, wind, transplant resistant varieties. Common Podocarpus, Buxus chinensis, Euonymus chinensis, Buxus chinensis, Buxus chinensis, Coral tree, Palm, Mosquito mother, Yucca, Gardenia flower, Bamao, Dragon claw locust, Bauhinia, Lagerstroemia, Begonia, Chinese plum, Longxing peach, etc., according to the time and area to determine the use of materials. Roof garden cultivation medium generally choose light materials, such as vermiculite, sawdust, earthworm soil, etc., but also some self-made media.

2. Select the positive and barren tolerant plants with shallow roots.

Most of the roof garden is full direct sunlight, light intensity is large, plants should try to choose positive plants, but in some specific small environments, such as under the flower stand or near the wall, the sunshine time is short, some semi-positive plant species can be appropriately selected to enrich the plant varieties of the roof garden, the planting layer of the roof is thin, in order to prevent the root system from eroding the roof building structure, plants with shallow roots should be selected as far as possible. Because the application of fertilizer will affect the sanitary conditions of the surrounding environment, roof gardens should be planted with barren plant species as much as possible. Such as Magnolia, Magnolia, Indian, Rhododendron, Peony, Camellia, Michelia, Rose, Orange, Kumquat, Jasmine, Canna, Dahlia, Cycas, Lily, Hundred Branches Lotus, Celosia, Dead Leaf Chrysanthemum, Peach Leaf Coral, Pittosporum, Bone, Grape, Wisteria, Ivy, Parthenocissus, June Snow, Osmanthus, Chrysanthemum, Radix Mai, Scallion Orchid, Jasminum, Yingchun, Frangipani, Velvet Lawn, Lotus, etc.

3. Choose plant species that are resistant to wind, lodging and water.

The roof is empty, the wind is generally stronger than the ground, especially in rainy season or typhoon, the combination of wind and rain is the greatest harm to the survival of plants, plus the thin roof planting layer, poor soil water storage performance, once the rainstorm, easy to cause short-term ponding, so we should try to choose some wind-resistant, not easy to lodge, but also able to withstand short-term ponding plants. Such as Elaeagnus sinensis, Lespedeza bicolor, Ilex acuta, Ilex cornuta, dwarf yew, Ligustrum lucidum, Ilex chinensis, Euonymus chinensis, Celtis sinensis, Cotinus coggygria, etc.

4. Evergreen plants, which can overwinter in winter.

The purpose of building roof garden is to increase the green area of the city and beautify the "fifth facade". The plants in the roof garden should be evergreen as much as possible, and the leaf-shaped and beautiful varieties should be used. In order to make the roof garden more colorful and reflect the seasonal changes of the garden, some color-leaf trees can also be planted appropriately. In addition, if conditions permit, some potted seasonal flowers can be arranged to make the garden have flowers all the year round. Such as winter tolerance, camellia, Chinese mosquito mother, Japanese privet, yew, camphor, Elaeocarpus, North American oak, Magnolia, fig, holly, palm, Sanwei sunflower, Canadian date, osmanthus, model docking white wax, model boxwood, Pittosporum, sisal, Araucaria, Phoenix wood, Schima superba, Manglietia rufa, Michelia, etc. Green lawn to evergreen lawn and Ophiophora japonica, Phragmites, green grass-based.

5. Select native plants as far as possible and introduce new green varieties appropriately.

Native plants have high adaptability to local climate, in the relatively harsh environment of the roof garden, the selection of native plants has twice the result with half the effort, while considering the area of the roof garden is generally small, in order to arrange it more delicate, you can choose some new varieties with higher ornamental value to improve the grade of the roof garden. Northern greening tree species are Vitex, Paulownia, Silver Wood, Forsythia, Yingchun, Pyracantha, persimmon, Qianzi Jun, Euonymus, pomegranate and so on.
