1. Cut buds cut buds is an important measure for artificially regulating growth and development. By cutting buds, excess buds are cut off leaving a few strong buds, so that the nutrients are concentrated on these strong buds and develop into strong ground stems and underground root systems. Can remove rot, roots, insects, play a role in pest control. Buds are cut in the spring in most parts of the country, and only the Xinjiang region cuts buds in the fall. It is better not to delay the cutting of buds in the spring, but it should not be too long to cut the buds. The method is to dig up the soil around the rhizome until all the old roots are exposed, then use a wooden knife to remove the soil outside the pit, and use a sharp cutting bud knife to cut off the new rhizomes or rot roots in the old and new rhizomes 1.5 to 2 cm, only in the old and new. Leave 5-8 robust buds at the root. Cutting buds require a smooth knife edge. Do not cut the root stems. After cutting, dry for 1 to 2 hours and then cover the soil.
2. Seedlings and Dingmiao seedlings began to sprout after unearthing, seedling height about 20 cm Dingmiao. The number of seedlings depends on the soil fertility, variety, spacing, and frame shape. Generally, 2 to 3 trees per plant are planted on large, elevated plots.
3. Lead vines vines and sparse leaves. When the seedlings are 40-60 cm high, the vines are tied to the lead wires with thin ropes or plastic ropes according to their growth habits and tied once every 3 to 5 days. Take it on a sunny day when the plants are slightly wilted to prevent breaking branches. When the seedlings reach a height of 2 meters, they begin to leaf thinly and sparsely. The side vines underneath the lead wire puller and the overly dense, overlapping and diseased branches and leaves are sparse so as to make the main vines grow robustly and reduce disease infections.
4. If there is water shortage during the growth period of irrigating and before the winter, it will have an impact on growth and yield. In particular, sufficient water must be ensured at the flowering stage, and about 7-8 times of irrigation will be needed during the entire growth period in Xinjiang.
5, fertilization can be combined with irrigation for fertilization. Nitrogen fertilizer at the seedling stage, 10 to 15 kg per acre, budding period and flowering time each one. 8 to 10 kg per mu, apply organic fertilizer before winter, about 3000 kg per mu.
6. The cultivator and weeding should be cultivated and irrigated in time after each irrigation or rain. Generally, the cultivars should be deep in the early and late stages of growth, and shallow during the flowering period to avoid damaging the root and affecting the yield.
