Jiexiang, whose branches are flexible, can knot at will without breaking; its flowers are yellow and fragrant, so it is called Jiexiang. Jiexiang is known as the love tree in China, which means that it likes to tie branches. What is the breeding method of Jiexiang with good wishes? Let's read on!
The best breeding time: ramets should be carried out before spring sprouting; cuttings should be carried out in February to March;
The best growing soil is fertile loam with good drainage. It grows luxuriantly on the humus rich and moist Rehmannia soil;
Growth humidity requirements: Jiexiang likes semi humid environment;
The best growth temperature: Jiexiang likes to be warm and cold resistant, and can endure low temperature within 20 ℃. In summer, when the temperature is high, the sprouting should be covered. Avoid direct sunlight, otherwise the plant will grow poorly. In winter, the temperature should be kept above 5 ℃. Zhengzhou area can overwinter in open field and has a certain cold resistance;
The best growth light: Jiexiang flowers like semi humid, sunscreen, Jiexiang like semi shade, planting or placement can be in the back of the north wall to the south, to avoid the hot summer, winter sun is the best. The Pot Planter should put it in the place with better sunshine from autumn to spring, and put it in half shade in summer. If it is too sunny, the leaves will turn yellow and the flowers will be few; if it is too cloudy, the fragrance of the flowers will be light.
Cultivation method of Jiexiang: fertilizer application:
It is better to cultivate fragrant fleshy roots in sandy loam soil than in saline alkali soil. Pot plants should put a layer of broken bricks and tiles at the bottom of the pot to facilitate ventilation and drainage. Transplanting or changing soil should be done after flower withering. Before the new leaf is unfolded, take the soil ball, so as not to affect the flowering in the next year. Watering and fertilizing should be moderate. It is better to water frequently in growing season to keep a little moist. Waterlogging is easy to rot roots, too dry is easy to fall leaves, which will lead to less flowers in the next spring. After anthesis, nitrogen fertilizer was applied once to promote the growth of branches and leaves, and in autumn, phosphorus and potassium fertilizer was applied once to promote the differentiation of flower buds.
Watering points:
In the growing season, Jiexiang should be watered frequently to keep a little moist. Waterlogging is easy to rot roots, too dry is easy to fall leaves, which will lead to less flowers in the next spring.
Pruning tips:
The sprouting ability of Jiexiang is strong, but the sprouting ability is weak, so it is not resistant to pruning. Every spring, the dry branches, diseased branches, overgrown branches and Cross branches are cut off to maintain the beautiful plant shape. The old branches should be pruned and renewed in time.
Breeding points:
There are several ways to propagate Jiexiang, such as branching, cutting and layering.
Ramets: before sprouting in early spring, take the strong sprouting seedlings, cut off the roots connected with the mother plant, and plant them in the field to survive. It can grow to 60 cm to 70 cm in a year.
Cuttings: generally from February to March, select robust branches, 10 cm to 15 cm in length, cut the lower part into a horse ear shape with a sharp knife, insert about half of the soil, compact, water, shade and keep the soil moist, root in 50 days, and transplant the next year.
Layering: select the thick and strong branches of tiller cluster, peel the half ring side pressed into the soil to the depth of xylem, and bury it in the soil. The branches are slightly exposed to keep moist. The next year, the mother branches can be cut off and cultivated separately. Transplantation should be carried out in winter and spring. It can be transplanted with bare root. Soil moisture should be kept during cultivation. Drought can easily cause defoliation and affect flowering. The old branches should be pruned to keep the tree plump.
Pest control:
1. Sclerotium Blight
High temperature, high humidity and poor ventilation are prone to this disease.
Control methods: 1) select and plant healthy and disease-free plants. 2) The removal of diseased or other organic residues, weeds in the soil is not conducive to the growth and shade of bacteria. 3) Pay attention to drainage, increase the application of organic fertilizer, promote the healthy growth of fungi and trees, improve the disease resistance. 4) Before planting, 70% pentachloronitrobenzene powder was used to disinfect the soil. 24g after 10 meters, soil was loosened after spraying. After the onset of the disease, the root was irrigated with 1:15 1 500 times solution of mercuric lime water, or 500 times solution of 50% tobuzin wettable powder, or 1% copper sulfate solution, or 10 ml / kg of weixiuling. Other prevention methods refer to Paeonia lactiflora.
2. Viral leaf retraction
It mainly damages the leaves. The disease is easy to occur in rainy and foggy weather.
Control methods: general control, after the disease can be 50% carbendazim, 50% tobramycin WP 800 times spray plants.
The value of Jiexiang: 1. Economic value
Stem skin fiber can be used as high-grade paper and artificial cotton raw materials.
2. Medicinal value
The whole plant can be used as medicine to relax muscles and activate collaterals, reduce inflammation and relieve pain. It can also be used as veterinary medicine to treat traumatic injuries and rheumatic pain.
3. Ornamental value
It can be cultivated for viewing. It is suitable to be planted in garden or pot. The whole plant can be used for medicine; the bark can be used as fiber for paper making; the branches are soft and can be used for basket weaving. With elegant posture and knotting branches, it is very popular and suitable for planting in front of court, roadside, waterside, stone room and wall corner. There are many potted plants in the north. The branches are soft, and can be knotted continuously when bent. They are often integrated into various shapes.
