Aviation spraying operation method for cotton defoliating agent under one-film three-row cultivation mode

Abstract

The invention provides an aviation spraying operation method for a cotton defoliating agent under the one-film three-row cultivation mode. In comparison with the prior art, the method of the inventionhas the following beneficial effects: (1) It is ensured from technical point of view that the effective spraying span of a plant protection drone just covers or slightly goes beyond cotton plants between adjacent two or more transfer lines during the single-line operation flight process. Farmers do not want to spray the agent too much on the transfer lines to waste the agent or pollute the soil,and their realistic demand is satisfied. Thereby, the precise, drug-saving and green operation is achieved; (2) the effective spraying span of the plant protection drone at different working heights cooperates with the ''one-film three-row'' equidistant-row cotton cultivation mode promoted and adopted in many places at home, the integration of agricultural machinery and agronomy in the spraying process of the plant protection drone is realized, and the above mode in the invention is in line with the state's general requirement on the integration of agricultural machinery and agronomy; and (3)the invention also provides a referential operation specifications for the precise aviation spraying of other pest control agents in the cotton field management process.

Description

technical field [0001] The invention relates to an operation method in which the effective spraying width of an aerial plant protection drone at different operating heights is coordinated with the cotton cultivation mode during the aerial spraying of cotton defoliation agents, so as to realize the precision, Save medicine, green operation. More specifically, it refers to an aerial spraying operation method of cotton defoliation agent under the cultivation mode of one film and three rows. Background technique [0002] In the later stage of cotton growth, the leaves begin to dry and fall off, and the cotton bolls gradually mature and open bolls. Nowadays, in order to facilitate the use of cotton pickers for mechanized cotton picking and reduce the impurity content, it is necessary to spray defoliation and ripening agents on cotton before machine picking. Defoliants such as magnesium chlorate, shedding treasure, etc. are sprayed on the cotton leaves and infiltrated into the l...

AI Technical Summary

Problems solved by technology

[0003] At present, in the aerial spraying of cotton defoliation agents using plant protection drones, it is found that operators often do not carry out aerial spraying operations from the perspective of agricultural machinery and agronomy integration
