Abstract

The invention belongs to the technical field of seedling cultivation and in particular relates to a winter greenhouse grafting and seedling formation method for apricot trees. The method comprises the following steps: (1) screening tree stock, namely transplanting the tree stock into a solar greenhouse between September 20 and October 10, preliminarily selecting survived stock, raising the temperature of the greenhouse between December 1 and December 10, wherein the low early temperature is gradually raised so as to screen proper stock; (2) collecting and storing apricot scions, namely collecting the scions during winter pruning, and performing sand storage in a ventilated storage house or ditching in the shade for performing sand storage; (3) grafting, namely grafting the apricot scions and the stock between January 20 and February 10, aligning the joint, and tightly sealing; and (4) cultivating after grafting, namely curing the grafted apricot seedlings, and flowering in the same year, so that the quality of the apricot seedlings subjected to greenhouse cultivation is improved, and the seedlings can be dug and delivered out of the nursery garden between September 20 and October 10 and supplied to the market. The winter greenhouse grafting and seedling formation method for apricot trees, provided by the invention, is high in operability and high in survival rate, and the survived apricot trees have extremely high yields and obvious practical values.

Description

technical field [0001] The invention belongs to the technical field of nursery stock cultivation, and in particular relates to a method for grafting apricot trees into seedlings in winter in a greenhouse. Background technique [0002] At present, in the cultivation process of crops, in order to better meet the needs of humans for crop quality and yield, it is often necessary to graft the scion to the rootstock, and the scion absorbs nutrients and water from the rootstock to the scion, and the rootstock directly affects the survival of the scion. And the growth of seedlings after grafting, therefore, rootstock can provide required nutrition and moisture for the growth of scion, maintain the normal growth of scion. [0003] Yet rootstock also needs to maintain the certain growth of self, after scion is grafted on stock, rootstock can still absorb nutrition for self germination growth, and the new shoot of rootstock can capture the nutrition of scion to a certain extent, thus s...
