Embodiment 1

[0035] In Cangzhou Jinsixiaozao production area, the first branch of jujube tree in the year is collected before the jujube tree sap flows in spring, cut into scions containing 1-2 buds and sealed with wax. From mid-April to late May, the scion is grafted to the stock that has been preserved and cultivated according to the method of the present invention, and is bound with the dark-colored binding tape used in the present invention. Use an alcohol thermometer to insert into the interface and measure the temperature of the interface. After the grafting survived, the redundant sprouts were removed in time, and the survival rate of the grafting was investigated in late September. 100 grafting joints (scions) were surveyed each time, and the survey results are shown in Table 1.

Embodiment 2

[0039]In the jujube producing area of ​​Taihang Mountains, the first branches of jujube trees in that year are collected before the sap of jujube trees flows in spring, cut into scions containing 1-2 buds and sealed with wax. From mid-April to late May, the scion is grafted to the stock that has been cultivated according to the method of the present invention, and is bound with the dark-colored binding tape used in the present invention. Use an alcohol thermometer to insert into the interface and measure the temperature of the interface. After the grafting survived, the redundant sprouts were removed in time, and the survival rate of the grafting was investigated in late September. The survey results are shown in Table 3.

Abstract

The invention discloses a method for improving the top grafting survival rate of jujube trees and relates to the field of jujube tree cultivation. The method comprises the following steps: treating top grafting jujube tree stocks; before sap flows in early spring, cutting off trunk branches according to needed tree shapes of the jujube trees; in a growth season, keeping 2-3 branches on each trunk branch as target branches and taking the target branches as stocks for grafting in the next year; preparing jujube tree scions; collecting branches with uniform thickness, full bud bodies and no plant diseases and insect pests before the jujube trees germinate from the middle and last ten days of March to the middle ten days of April in the next year; cutting each 1-2 burs into the scions and carrying out wax sealing; after cooling, putting the scions into a freshness-keeping and refrigerating for later use; from the middle ten days of April to the last ten days of the May, grafting the scions on the treated jujube tree stocks; and immediately and tightly binding grafted parts of the scions and the stocks through a deep-color polyethylene plastic thin film. According to the method disclosed by the invention, technical problem that the grafting fails because conventional top grafting stocks of the jujube trees are aged and have weak vitality, the scions and the stocks cannot be effectively matched, and the connected thin film on a connector is likely to be pecked by birds can be solved.

Description

technical field [0001] The invention relates to the technical field of jujube cultivation, in particular to a method for improving the survival rate of jujube high grafting. Background technique [0002] Jujube is a unique fruit tree native to my country. Jujube fruit is a famous nourishing product, which has the effects of calming, calming the nerves, nourishing blood, strengthening the brain, anti-cancer, and enhancing immunity. Jujube fruit is rich in nutrients, including various organic acids and multivitamins. In addition, jujube fruit also contains important medicinal substances cyclic adenosine monophosphate, cyclic guanosine monophosphate and flavonoids, 17- 18 kinds of amino acids are very beneficial to human health. [0003] Jujube has been cultivated for more than 3,000 years. Especially in recent years, with the development of agricultural production and scientific research, a large number of fine varieties have been screened out. Jujube tree propagation and ma...
