Grapes are less demanding for soil and are adapted to sandy soil, gravel soil, light clay and border soil, with the exception of heavy clay and saline soil. However, it is most appropriate to have the micro-acid to micro-alkaline sand or gravel border soil with deep earth cover, good drainage, estrangement and appropriate moisture. Drought-resistant, flood-resistant. Grapes are grown in a variety of varieties, and the country's most common famous grapes are the dragon eye, the black hunk, the great peak, milk, nuclear-free white, the chicken heart, etc。
Grapes are grown on the basis of the customary practice of grapes to choose the place where they are grown with sufficient sunlight, good ventilation and high ground. Before planting, the ground is turned deep enough to produce enough decompressed fertilizers, then the grape seedlings are planted on the basis of their planting status, and the roots are stretched out so that they cannot be buried deep enough to plant them on the piles that rise up. Then it will be a little twirling, so that it will crush the earth, so that it will water its roots, and the vines will be tied to the pillars or to the mats。
The conservation focus should be on:
Water and fertilizer. Grapes are dry, the result of flowering should be less or less watered, and the arid areas of the northern part of the winter require soil moisture. Rational fertilization is key to grape growth and outcomes. In individual winters, nitrogen, phosphorus-based fertilization should be applied, followed by phosphate fertilization one to two times before the flower, followed by phosphorus and potassium fertilization one to two times。
2 integrative and trim. Intangibles tend to be shaped by different methods of planting, such as tectonics, where it is generally desirable to focus on lifting-side branches into large tree crowns, and to cut and trim them after the coronary has been produced, in order to form more equitable branches, while fence-forms and tectonics can be grown on a single-planted basis, with only-burned chickens, with short-stamped substrates, and can be repaired into longer-lasting branches stretching parallel to the layers of the fence。
Cuts should be kept at a reasonable density during each year's hibernation, followed by a short cut at the reserved position of only one or two buds, so that it may grow into a new branch of the prefix next year. Interrupted cropping is done every year so that each year it can produce a definite yield。
