Method for achieving grafting and cultivation in the same year as planting for jujube trees

Abstract

The invention relates to a method for achieving grafting and cultivation in the same year as planting for jujube trees. The method is characterized by comprising the steps that (1) jujube tree seedlings are planted in mid-to-end of April, temporary planting is carried out during lifting of the seedlings, the seedlings are transported to a planting orchard and are dipped into slurry to be kept moist when being transported, the roots of the jujube trees to be planted are soaked with rooting power during planting, and then planting mulching is carried out; (2) scions of an introduced new species of jujube trees are collected in the end of March to the beginning of April, and after being cooled, the scions are put into a storage bag and stored at the temperature of 4 DEG C for use; (3) when the planted jujube trees grow to the end of May and sprouts grow to 5-10 cm, it can be determined that the jujube trees survive, the planted jujube trees are pruned to 30 cm, the sprouts are pinched off, and grafting is carried out according to the cleft grafting method; (4) stock sprouts of the grafted trees are pinched off, the 800-fold drought-resisting KangHanLong leaf fertilizer is sprayed once every ten days after the sprouts appear and leaves spread, and pinching is carried out on all the grafted trees in the beginning of August. Compared with the orchard building method of introducing seedlings, a large-area jujube orchard can be built quickly through the orchard building method, cost is low, and orchard building efficiency is high.

Description

technical field [0001] The invention relates to a method for grafting and cultivating jujube trees in the same year when they are planted. Background technique [0002] The breeding of excellent seedlings of jujube mainly adopts grafting technology. At present, the common one is to develop seedlings by sowing wild jujube kernels, and then grafting scions of excellent seedlings in the second year; After the garden is planted and survived, the scions of excellent seedlings are grafted in the second year. Use the second method to establish a jujube orchard, and the jujube trees adapt to the local climate and environment and have strong disease resistance and cold resistance. But the traditional method of grafting in the second year after building a garden by root tiller seedlings is longer. The introduction of high-quality large-scale seedlings from other places to build gardens, first, the price of seedlings is expensive, and the transportation cost is high; second, because ...

AI Technical Summary

Problems solved by technology

Introduce high-quality large-scale seedlings from other places to build gardens. First, the seedlings are expensive and the transportation cost is high; second, the long-distance transportation of seedlings is easy to lose water and the survival rate is low.
