Exogenous hormone spraying and applying device used before flowering of maize

Abstract

The invention relates to an exogenous hormone spraying and applying device used before flowering of maize. A liquid accumulating cavity is formed in a knapsack spraying and applying tank; an exogenoushormone tank is mounted at the lower end of the knapsack spraying and applying tank; an exogenous hormone storing cavity is formed in the exogenous hormone tank; the lower end surfaces of the liquidaccumulating cavity and the exogenous hormone storing cavity are arc surfaces which are gathered to the middle part; a liquid flowing out pipe is mounted at the lower end of the liquid accumulating cavity; an exogenous hormone drawing pipe is arranged at the middle part of the exogenous hormone storing cavity; the exogenous hormone drawing pipe and the liquid flowing out pipe are connected with amixing pipe; the mixing pipe is connected with a mixing mechanism; and the mixing mechanism is connected with an exogenous hormone delivery pipe. Before the exogenous hormone spraying and applying device used before flowering of maize disclosed by the invention is used, liquid and high-concentration paste / ointment exogenous hormone dispersion liquid are temporarily diluted to practical used concentration, and homogenizing is performed through the mixing mechanism with a spiral flow channel. Through the adoption of the exogenous hormone spraying and applying device used before flowering of maize disclosed by the invention, the problem that during present exogenous hormone spraying and applying, the exogenous hormone is not compounded during using, so that deterioration is liable to generate, and activity is reduced or lost is solved.

Description

technical field [0001] The invention relates to the related field of exogenous hormone spraying, in particular to an exogenous hormone spraying device and a spraying method before popcorn flowers. Background technique [0002] Phytohormones are a type of organic substances produced by the plant's own metabolism, and move from the production site to the action site. They are trace substances that have obvious physiological effects at very low concentrations. They are also called plant natural hormones or plant endogenous hormones. . They regulate the growth, development and differentiation of plants separately or in coordination with each other in terms of cell division and elongation, tissue and organ differentiation, flowering and fruiting, maturation and senescence, dormancy and germination, and in vitro tissue culture. The flexibility and diversity of this regulation can be achieved by changing the concentration and ratio of exogenous hormones, thereby changing the level...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of exogenous hormone spraying device and its spraying method before popcorn flower, to solve the problem that exogenous hormone is not prepared and used in current exogenous hormone spraying, and there is a long time between preparation and spraying. Interval, the spraying operation is not friendly and flexible enough, it is not easy to control the amount of spraying if it is not ready to use, and there is a lot of waste of exogenous hormones
