Embodiment Construction

[0030] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0031] see figure 1 , figure 2 As shown, the present invention is an aerial spraying operation method of cotton defoliation agent under the three-film twelve-row cultivation mode, which includes the following steps.

[0032] The first step: determine the average height of cotton plants under the three-film twelve-row cultivation mode, and the average width of cotton plants in the width direction of three adjacent film films

[0033](A) The cotton variety planted in a certain plot is Lumian 532. The plot adopts the "three-membrane twelve-row" cultivation mode. The specific specifications are: on the mulch film with a width of 1.3m according to the "20cm+40cm" There are 2 groups of 4 rows of cotton plants in the method of large and small rows. Each group of cotton plants is composed of 2 rows of cotton plants with a row spacing of 20cm. The width of ...

Abstract

The present invention provides an aerial spraying operation method of cotton defoliation agents under the three-membrane twelve-row cultivation mode. Compared with the prior art: (1) The present invention ensures that the plant protection UAV can fly in a single route from a technical point of view During the process, its effective spray width just covers or slightly exceeds the average width of cotton plants formed by 12 rows of cotton plants in the width direction of three adjacent mulch films, which satisfies the desire of growers not to spray too much liquid medicine on the wider handover row This also corresponds to the 12 rows of cotton plants formed by the single-width operation of large planters, and realizes the integration of agricultural machinery and agronomy in the process of spraying pesticides by plant protection drones, which meets the national requirements for agricultural machinery. General requirements for agronomic integration; (2) The present invention also provides a reference operation specification for the precise 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 agent under the three-film twelve-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...
