Saccharose spraying method capable of promoting apple flower bud initiation

Abstract

The invention discloses a saccharose spraying method capable of promoting apple flower bud initiation. The saccharose spraying method capable of promoting apple flower bud initiation comprises the following steps of dissolving saccharose with clear water, and spraying saccharose solutions twice, wherein the concentrations of the saccharose solutions are respectively 15000mg L<-1> and 20000mg L<-1>, and the spraying dates of the twice spraying are respectively 29 days after full blooming and 36 days after the full blooming. After saccharose treatment is performed, the soluble sugar content of brachyplast terminal bud adjacent leaves is obviously increased; when 40 days after the full blooming, the contents of four types of soluble sugars, namely the saccharose, fructose, glucose and sorbitol are obviously higher than the control; the saccharose treatment promotes accumulation of soluble sugar in brachyplast terminal bud and leaves, which is relatively beneficial to flower bud formation; saccharose spraying treatment improves the soluble sugar contents of the brachyplast terminal buds and the adjacent leaves thereof, so that certain influence on a branch type group is achieved, the germination rate of Nagatomi apple branches is obviously increased, and the effective flower rate of brachyblast is obviously increased.

Description

technical field [0001] The invention belongs to the technical field of fruit tree production and cultivation, and in particular relates to a sucrose spraying method for promoting the growth of apple flower buds. Background technique [0002] At present, my country is the world's largest producer of apples, and its area and output both rank first in the world. 'Fuji' is the main apple variety in China, and its cultivation area accounts for more than 65%. It is one of the important bottlenecks restricting the increase of my country's apple production. [0003] At present, the agronomic measures to overcome Fuji’s difficult flowering in production mainly include bud carving, girdling, and branch pulling. Although these measures can relieve Fuji’s difficult flowering to a certain extent, they will cause great damage to the tree body and the technical process is complicated. Time-consuming and labor-intensive, difficult to standardize. Contents of the invention [0004] The p...
