Flower thinning method for seedless litchis

Abstract

The invention belongs to the technical field of litchi planting, and particularly relates to a flower thinning method for seedless litchis. The flower thinning method for the seedless litchis comprises the following steps of 1, firstly cutting off a first side spike and a second side spike in a litchi spica upwards from the base of the spica; 2, cutting off all side spikes of the spica except a third side spike and a fourth side spike; 3, reserving two first branch spikes on each side spike of the third side spike and the fourth side spike, and cutting off all other branch spikes. By means ofthe method, the side spikes and branch spikes needed for flowering and fruit bearing are reserved with purposes, sufficient nutrients are reserved for the spica which is needed for flowering and fruitbearing, the waste of nutritional substances is reduced, and utilization of the nutrients is more sufficient; moreover, a large number of phenomena of flower and fruit dropping of the seedless litchis can be reduced, the yield of the fruits is significantly increased, and the quality of the fruits is significantly improved.

Description

Technical field [0001] The invention belongs to the technical field of lychee planting, and specifically relates to a method for thinning the flowers of "non-seeded litchi" litchi. Background technique [0002] The tree body load is the main factor that affects the yield and quality of the fruit. The tree body load can be controlled by pruning the amount of buds or branches, or by thinning flowers and fruits. Flower thinning and fruit thinning technology is one of the main technologies to ensure that fruit trees efficiently preserve flowers and fruits and improve fruit quality. This technology has been studied and obtained on apple, plum, pear, kiwi, citrus, loquat, yellow bark and other tree species. Confirmed. [0003] "Seedless lychee" is one of the better varieties of lychee. Compared with the seedless lychee, there are larger differences in flower and fruit management and certain cultivation difficulties. "Seedless Li" has a large flower volume and a large number of side flo...

AI Technical Summary

Problems solved by technology

"Seedless lychee" has a large amount of flowers and a large number of side flower spikes, but the growth of the flower spikes is weak, and there is a so-called phenomenon of "flowers but not fruit". Excessive amount or unreasonable flower panicle structure will cause very serious physiological fruit drop and pre-harvest fruit drop, which will eventually affect the yield and quality of the fruit
