(i) period of planting
Mountain grapes are generally suitable for spring planting and can be planted when more than 50 cm deep is frozen。
(ii) plantation techniques
1. Sapling: 24 hours before planting, immersion of the whole seedling into the water。
2. Pre-plant water: on a well-established planting belt, a tree shall be planted at a distance of 1 m or 1. 5 m, a round shall be dug at a distance of 40 cm in diameter and 30 cm in depth, and the centre shall be the position of the tree, the soil shall be added to the cave and shall be modulated with a fine, well-created organic material, which shall be filled back to half the den, the centre shall be soared, the chosen tree shall be placed on the central corset with its feet, and the roots shall be spread around it. New bends to the surface, then crushing the rest of the earth to the root, shaking the trees and stepping on it. Be careful not to plant too deep, lest new earth be stained. A circular water dish of 50 cm in diameter is made of soil around the tree, so as to fill the water. When the water dipped, the soil was taken from between the lines and buried on it, and it was requested that the marks of the water not be exposed and that it be prevented from being drained. And a small pile of earth shall be made for the seedlings, and a part of them shall be laid on the ground。
(iii) primary plant varieties and pollinating trees
The first, second and second parts of the left mountains are good quality and high yield. If a park is built on the first or second left of mount nord, it must be paired with a double-chance or double-red variety, with a general ratio of 2:1 to increase production。
(iv) post-plant seedling management
Some 10 days after planting, it will be sufficient to remove the ground that is planted and to level the new parts of the trees that are exposed, at which point many of the buds have begun to develop. As a growing branch of a live tree, it grows to about 15 cm, with a stick placed near the seedling, tied to the stick with a cloth, to prevent scratching and gradually draw it to the surface. The fresh steeds of fresh springs are wiped out, so that they may prolong their growth. By mid-august, all new sites will be taken to the centre to facilitate maturity. During the growth of the seedlings, if the weather is dry, water should be watered in due course so as not to affect their normal growth. Timely spraying in case of infestation。
