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 wide and narrow row cultivation mode, including the following steps.

[0032] Step 1: Determine the average height of cotton plants and the average width of cotton plants within the range of two adjacent mulch films under the wide and narrow row cultivation mode

[0033](A) The cotton variety planted in a certain plot is Lumian 532. The plot adopts the "wide and narrow row" cultivation mode. The specific specification is to sow 2 rows of cotton plants with a row spacing of 50cm on the plastic film. The 2 rows of cotton plants A "narrow row" is formed, and a "wide row" is formed by the handover row formed between two adjacent mulch films because there is no sowing cotton plant, and the width of the "wide row" is...

Abstract

The present invention provides an aerial spraying operation method of cotton defoliation agents under the wide and narrow row cultivation mode. The effective spray width just covers or slightly exceeds the average width of cotton plants formed by 4 rows of cotton plants and 1 transfer row on two adjacent mulch films, which satisfies the need for growers not to spray too much liquid on the transfer row, that is, " (2) The present invention coordinates the effective spray width of plant protection drones at different operating heights with the "wide and narrow row" cotton cultivation mode popularized and adopted in many places in China Correspondingly, the integration of agricultural machinery and agronomy in the spraying process of plant protection drones is realized, which meets the overall requirements of the country for the integration of agricultural machinery and agronomy; (3) The present invention provides a precise aerial spraying of other pest control agents in the cotton field management process. An operational norm 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 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,...
