Aerial spraying operation method of cotton leaf-removing medicament in wide-narrow row cultivation mode

Abstract

The invention provides an aerial spraying operation method of a cotton leaf-removing medicament in a wide-narrow row cultivation mode. Compared with the prior art, (1) the aerial spraying operation method of the cotton leaf-removing medicament in the wide-narrow row cultivation mode ensures that the effective sprinkling width of a plant protection unmanned aerial vehicle exactly covers or slightlyexceeds the average width of cotton plants formed by four rows of cotton plants and one connecting row on two adjacent mulching films in the single-line operation flight process from the technical point of view, thereby meeting the practical requirement of a planter who does not want to spray the liquid medicine too much in the connecting line, namely a wide line, for not leading to liquid medicine waste and soil pollution; (2) the effective sprinkling width of the plant protection unmanned aerial vehicle under different operation heights cooperates with a cotton cultivation mode 'wide-narrowrow' which is widely popularized and adopted in many places in China, so that the integration of agricultural machinery and agronomy in the pesticide spraying process of the plant protection unmannedaerial vehicle is achieved, and the overall national requirement of the integration of agricultural machinery and agronomy is met; (3) the aerial spraying operation method of the cotton leaf-removingmedicament in the wide-narrow row cultivation mode provides a reference operation standard for the accurate aerial 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 agents under the wide and narrow row cultivation mode. 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 leaves,...

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
