High-efficiency scanning spraying method of whole plants of Allium fistulosum

Abstract

The invention discloses a high-efficiency scanning and spraying method of whole plants of Allium fistulosum. The scanning spraying method is achieved through combination of a conventional power sprayer with a medicine switch, a spray main switch, a split-flow tee, double handles, double spray rods, double spray heads and other special spraying components, the spraying positions of the left-and-right two sets of spray heads can be changed, and the directions of nozzle holes of the spray heads can also be changed through rotation; and during spraying operation, the relative positions of the left-and-right two sets of spray heads are kept static, and are consistent with the advance direction of an operator, the advance trajectory of the spray heads is a straight line during the scanning spraying operation, and the static scanning spraying width is larger than the width of crop targets, so that efficient and precise scanning spraying is performed on three different agronomic-trait crops which include Allium fistulosum crops, tiled-type crops and low-cluster-type canopy plants. When the method is compared with commonly-used knapsack manual sprayers or knapsack electric sprayers, the work efficiency can be increased by 3 times or above, water can be saved by 60%, chemicals can be saved by 65%, and the control effect of pests and diseases can be improved by 8-33%; and moreover, the novel scanning spraying mode for the three types of crops which include Allium fistulosum is developed, and the level of the spraying technology and spraying devices of the three types of crops can be improved.

Description

technical field [0001] The invention relates to an efficient, accurate, uniform, thoughtful and convenient method of scanning and spraying pesticides, in particular to three scanning and spraying methods for green onion crops, dwarf cluster crops and flat crops, belonging to agricultural plants Protection of spray technology fields. Background technique [0002] Pesticide varieties, pesticide use technology and plant protection machinery are the three major elements in the prevention and control of plant diseases and insect pests. Over the years, in agricultural production at home and abroad, most of the attention has been paid to the selection of "pesticide varieties" while ignoring the importance of "pesticide use technology" and "plant protection machinery". Performance: Due to the advancement of pesticide technology, the insecticidal activity of modern deltamethrin pesticides is 1600 times higher than that of DDT pesticides in the 1940s, but the amount of active ingredie...

AI Technical Summary

Problems solved by technology

There will inevitably be heavy spraying areas and missed spraying areas in the swing spraying method, and the uniformity and density of the sprayed chemicals are difficult to control, resulting in poor control effects. Therefore, this phenomenon makes the reciprocating swing spraying, which is already inefficient, The spraying efficiency of the spraying head is doubled and the effect is poor. Due to the ever-changing agronomic traits of plants such as plant type, height, leaf shape, leaf potential, cultivation orientation, site and field conditions, one spraying device cannot adapt to all types. Plants are sprayed efficiently, accurately, conveniently, and economically. For this reason, there is an urgent need to research and develop efficient and precise spraying methods and equipment for different types of agronomic traits without repeated spraying and missed spraying.
