Late-blossom prunus armeniaca stock for avoiding late spring coldness and method for mainly planting apricots to avoid late spring coldness by using late-blossom prunus armeniaca stock

Abstract

The invention discloses a late-blossom armeniaca sibirica rootstock for avoiding late spring coldness and a method for avoiding late spring coldness by using the late-blossom armeniaca sibirica rootstock for main planting apricots, and the late-blossom armeniaca sibirica rootstock is WHZM-1 late-blossom armeniaca sibirica or WHZM-2 late-blossom armeniaca sibirica. The method for avoiding late spring coldness comprises the following steps: selecting a basic stock: taking armeniaca sibirica as the basic stock; selecting an interstock: taking the late-blossom armeniaca sibirica stock for avoiding the late spring coldness as the interstock; selecting a main planting apricot scion; in spring or summer, the interstock serves as a scion to be grafted to the basic stock, and after grafting is completed, an interstock grafted seedling is obtained; the main planting apricot scion is grafted to the interstock of the interstock grafted seedling, and after grafting is completed, the main planting apricot grafted seedling capable of avoiding late spring coldness and delaying the flowering phase is obtained. According to the cultivation method for the main cultivated apricots, the common industrial problems that the main cultivated apricots are prone to being damaged by late spring coldness and late frost in the production process are stably solved at a time with low cost and high efficiency, and technical guarantee is provided for high yield and stable yield of the apricots.

Description

technical field [0001] The invention relates to the technical field of main planting apricots to avoid the cold in spring. Specifically, it is a rootstock of Wanhuashan apricot used to avoid the spring cold and a method for using the rootstock of Wanhuashan apricot to avoid the spring cold. Background technique [0002] Apricot is a traditional fruit tree with a long history of cultivation in my country, and it is also a woody grain and oil economic tree species with great development potential. However, most of the apricot trees in production have the phenomenon of "no harvest in ten years and nine years" and "seeing the flowers but not the fruit". Apricot trees bloom earlier, and the average daily temperature for 10 consecutive days is greater than 7.5 ℃. In my country's Xinjiang, Gansu, Qinghai and other regions, apricot flowers begin to bloom from late March to early April, and regions such as Inner Mongolia, Hebei, and Liaoning also begin to bloom in mid-to-late April...

Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is to provide a kind of late-flowering mountain apricot rootstock for avoiding the cold spring and the method for using the late-flowering mountain apricot rootstock to avoid the cold spring, so as to solve the problem of apricot yield reduction or even no harvest of the main apricots caused by the cold spring and late frost. problems, and the current cultivation measures used to avoid the cold spring are ineffective and affect the growth of trees
