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 invention provides an aviation spraying operation method for a cotton defoliating agent under a three-film twelve-row cultivation mode. In comparison with the prior art, the method of the invention has 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 the average width of 12 rows of cotton plants in the width direction of adjacent three mulching films during the single-line operation flight process. Farmers do not want to spray the agent too much on the wider transfer line to waste the agent or pollute the soil, and their realistic demand is satisfied. The above mode is also corresponding to the 12 rows of cotton plants formed by single-width operation of a large planter. Thereby, the integration of agricultural machinery and agronomy in the spraying process of the plant protection drone is realized, which is in line with the state's general requirement onthe integration of agricultural machinery and agronomy; and (2) 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 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...
