Method for improving setting rate of autumn cucumber

Abstract

The invention relates to a method for improving the setting rate of autumn cucumber. The method is characterized in that a pesticide preparation with the active components containing amino-oligosaccharin and ethephon is mixed, and is diluted with water according to a dosage of ethephon in the mixed preparation of 100-200 mg / kg, and the obtained diluted solution is uniformly sprayed on autumn cucumber seedlings in the 2-leaves 1-center stage and in the 4-6-leaves stage until the leaves are moist. The method substantially improves the pistillate flower differentiation rate of summer cucumber and autumn cucumber, the setting rate, the quality of cucumber and the stress resistance of crops to reach yield increase and income increase effects.

Description

technical field [0001] The invention relates to the field of phytochemical nutrition control, in particular to a method for improving the sitting rate of autumn cucumbers. Background technique [0002] Cucumber is a kind of temperature-loving crop. The yield of cucumber is closely related to its biological characteristics. Cucumber flowers have both male and female primitive bodies in the early stage. During the development process, sexual differentiation begins. One side continues to develop, while the other side degenerates. The main factors affecting the sex type differentiation of cucumber flower buds are temperature and sunshine. Low temperature and short sunshine are conducive to the differentiation of female flowers, while high temperature and long sunshine are conducive to the differentiation of male flowers. Cucumbers planted in autumn are under high temperature and long sunshine conditions, the female flowers are less differentiated, the melon sitting rate is reduc...

AI Technical Summary

Problems solved by technology

[0005] In view of the fact that the female flower differentiation of cucumbers planted in summer and autumn stubble is less, and the melon sitting rate is not ideal, there is an urgent need for a method that can improve the female flower differentiation of cucumbers planted in summer and autumn stubble, and promote the melon sitting rate to improve the economic benefits of growers

At present, there is no relevant report on the method of improving the differentiation of female flowers and the rate of melon sitting by using a mixed composition with amino-oligosaccharins and ethephon as active ingredients to treat cucumber seedlings in summer and autumn.
