Introduction of two breeding methods of Grey Leaf

Huili is a shrub or small tree, evergreen all the year round, plump plant type, is an excellent variety of courtyard flowers, and now there are often flower friends to make Huili into a potted plant. Artificial propagation of Huili can be done by cutting and ramet, and the editor will give you a brief introduction.

Huili

I. Cuttage

Huili reproduction, with cutting, sowing, pressing, ramet can be used, but mainly cutting in the north. From July to August, the branches of the same year were cut into 8 cm and 10 cm for cuttings, and 3-4 top leaves were retained and inserted into clean river sand. They were placed in the greenhouse and rooting in 40-60 days, with a survival rate of more than 85%.

2. Ramets

Between March and April, when the plant begins to germinate, remove the clump-shaped plant from the flowerpot, or dig up the tufted plant from the soil, shake off part of the persistent soil, and cut it with a sharp knife where the root system is weak. so that each clump with at least 2 to 3 stems, and with part of the intact root system, separately planted or potted. In addition, there are many sprouting tillers on its roots near the ground, which can be truncated from the roots and planted separately.

The main value of the planting method of Huili

Cinnamomum cinnamomum is a fine garden and indoor foliage plant with rich fragrance, luxuriant branches and beautiful tree shape. So how does Grey grow it? What's the value? Let's learn about it next.

First, the planting method of Huili

1. Soil: choose loose, fertile and well-drained sandy loam for cultivation. Potted plants in the north can be prepared with 7 parts of rotten leaf soil, 1 part of river sand, 1 part of retted organic fertilizer and 1 part of fermented sawdust. During the growing season, the potted plants were loosened once a month to keep their roots in a good state of penetration.

2. Temperature: choose the environmental conditions with warm climate. The suitable temperature for the growth of Cinnamomum mandshurica is 18-32 ℃, and it will inhibit the plant growth when the summer temperature is higher than 38 ℃. The field cultivation in some areas of South China can survive the winter in the open field, while the pot planting in the north of the Yangtze River requires that the greenhouse temperature is not lower than 5C in winter.

3. Lighting: choose plenty of sunshine, but with certain shading conditions. Full light can be accepted in spring and autumn, and shading is required in summer, or be moved under the shade of big trees, at least to avoid direct sunlight for several hours before and after noon. It is particularly noteworthy that there is a sharp rise in temperature and strong light on a sunny day after a long rain from June to July. Shading must be done to prevent young shoots and leaves from being burned.

4. Moisture: water is watered in spring and autumn to keep the basin soil moist, and stagnant water should be strictly prevented in overcast and rainy seasons. in hot summer, spray water once in the morning and afternoon to increase humidity and cool down. For indoor potted plants in winter, it is appropriate to keep the potted soil slightly tidal, and spray appropriate amount of water to the leaves around noon when the temperature is relatively high.

5. Fertilization: potted plants apply thin mature cake fertilizer and water once a month in the growing season, topdressing phosphorus and potassium fertilizer once before flowering in May to promote plant flowering, and topdressing 1-2 times after autumn to pass the winter safely. In order to prevent the leaves from yellowing, 0.2 ferrous sulfate was added when watering and fertilizing in the growing season.

6. Pruning: Huili sprouts and tillers are relatively strong, extremely resistant to pruning, and can be shaped and pruned at will during the growing period, usually cut into spherical, platform and fan shape. in order to maintain a beautiful tree shape, the tillering buds at the bottom of the plant should be cut off in time so as not to consume too much nutrients.

Second, the main value of Grey.

1. Horticultural value: Cinnamomum cinnamomum is large, fragrant, green and green all the year round, grows well, has luxuriant branches, beautiful tree shape, nearly fleshy leaves, dark green and glossy leaves, and is an excellent garden and indoor foliage plant.

2. Greening value: strong anti-pollution ability, which is suitable for the greening of road isolation belts, trunk roads, forest belts and landscape nodes.

The above is the introduction of the planting method and the value of Huili. Huili can produce volatile oil with significant bactericidal effect, which is very suitable for breeding indoors.

The root insertion propagation of Cinnamomum chinense (Picture) is also called African jasmine, which belongs to the family Brucaceae and Grifoliaceae. Its plump plant shape, coupled with green and green leathery leaves, is very likeable. It is a popular indoor foliage plant in recent years. After several years of cultivation, it is found that the root segments of the plants in the vigorous growth period can be cut and propagated when the ambient temperature is 20 ℃ to 30 ℃.

Using rotten leaf soil or fine river sand mixed with a small amount of phosphorus and potassium compound fertilizer and well permeable and breathable as the substrate, the good light can be selected in the greenhouse to make a small arch shed, and the family root can be used to make a small sunny bed in the sunny place, and a small amount can also be replaced by a deep basin cover film. Lay the substrate in the small arch shed (Xiaoyang border, deep basin), the depth is not less than 20 cm, combined with changing the basin, select the plant with good rooting and no disease and insect pests as the mother plant. Carefully remove part of the persistent soil, dig the root with a diameter of 0.3cm to 2cm, and cut the root segment with a length of 6cm to 10cm according to the upper and lower oblique cut (the amount of excavation should not exceed 1/3, otherwise the mother plant has serious deciduous leaves). If it cannot be cut immediately after cutting, it should be tied up and stored in a cool and moist place, do not blow in the sun, so as to avoid excessive loss of water. In order to improve the rooting rate, 1000ppm's ABT1 rooting powder solution can be prepared. After soaking for 5 hours, the seed root is cut upright according to the big head. If the root is thin and soft, you can use a small stick to punch holes in the ground before cutting. After planting, it is appropriate to cover the culture substrate with the top of the root tip flat with the ground after watering, apply carbofuran 3% granule 15g / m2 to 30g / m2, irrigate evenly with 95% dimethylethasone soluble powder 2000 times or 50% methylekurin wettable powder 2000 times, seal with transparent plastic film, and then spray 95% diexamethasone soluble powder 500 times solution once a week. Pay attention to keep the cutting bed moist regularly. The temperature should be ventilated when the temperature exceeds 35 ℃. It can take root and sprout in about 45 days. After that, 0.3% urea water and 0.3% potassium dihydrogen phosphate solution are sprayed once or twice a week, when the length reaches 10 cm, hit the top and promote the side, and when the length reaches 15 cm to 20 cm, it is then transplanted to the pot for maintenance and management, and a small basin of beautiful ash wood can be formed that year.
