The time of excavation can be determined by using the phenology period of some fruit trees as the indicator plant. Generally, it is appropriate to remove the cold-proof material at the beginning of the flowering stage of the local peach or the apricot and other cultivated varieties.
Unearthing method to remove the cold soil, first in the cold soil on both sides of the dumping of soil, and then remove the cover of the upper part of the vines until the emergence of grape vines. After removing the cold-proof material, you must renovate the noodles. In order to prevent the shoots from draining, the shoots will germinate neatly, and the shoots will be put on the ground for a few days after unearthing, and the shoots will be put on the shelf when the buds begin to sprout.
The finishing bracket must be trimmed every year before the grapes are unearthed on the shelf, and the iron wire is tightened. The tilted and loose rack must be straightened tightly.
The clear roots are planted on grafted plants. New shoots often occur at the scion sites above the interface. When the shelves are unearthed, they should be checked on a vine-by-vine basis. All main vine bases should be thoroughly cleaned. Try not to make the main vine close to the ground. Landing roots. Once the roots of the scion are rooted, the roots of the rootstock will naturally die and the plants will become self-rooted, weakening the resistance. During the growing season, it should also be checked frequently and rooted in time.
To prevent the flow of grape injury, in order to prevent the occurrence of injury, do not prune before germination, and pay attention to the excavation of the branches and the shelves during the agricultural operations before and after the germination. Take special care and carefulness to avoid injury to the branches.
