Aerial Spraying Operation Method of Cotton Defoliant in One Film and Three Row Cultivation Mode

Abstract

The present invention provides an aerial spraying operation method of cotton defoliation agents under the cultivation mode of one film and three rows. Compared with the prior art: (1) The present invention guarantees 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 can just cover or slightly exceed the cotton plants between two or more adjacent transfer rows, which satisfies the reality that growers do not want to spray too much liquid medicine in the transfer row to cause waste of liquid medicine and soil pollution (2) The present invention combines the effective spray width of plant protection drones at different operating heights with the "one film three rows" cotton cultivation mode with equal row spacing popularized and adopted in many places in China. Collaborative correspondence realizes the integration of agricultural machinery and agronomy in the spraying process of plant protection UAVs, which meets the overall requirements of the country for the integration of agricultural machinery and agronomy; (3) The present invention provides precise aerial spraying of other pest control agents in the cotton field management process. A work specification that can be used for reference.

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...

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
