Aerial spraying operation method of cotton defoliation agent under one-film six-row cultivation mode

Abstract

The present invention provides an aerial spraying operation method of cotton defoliation agent under the one-film six-row cultivation mode. Compared with the prior art: (1) The present invention ensures the flight process of the plant protection UAV in a single route operation from a technical point of view Among them, the effective spray width just covers or slightly exceeds the average width of cotton plants formed by 6 rows of cotton plants in the width direction of a single mulch film, which satisfies the desire of growers not to spray too much liquid medicine in the wider handover row to cause pesticide damage. The actual needs of liquid waste and soil pollution; (2) The invention coordinates the effective spray width of the plant protection drone at different operating heights with the "one film six rows" cotton cultivation mode popularized and adopted in many places in China, and realizes The integration of agricultural machinery and agronomy in the spraying process of plant protection drones meets the overall requirements of the country for the integration of agricultural machinery and agronomy; (3) The present invention provides a reference for the precise aerial spraying of other pest control agents in the cotton field management process job specification.

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 one-film six-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, abs...

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
