Problems solved by technology

The topping agent of this invention is a water emulsion, and the solubility with water in the water emulsion dilution process is not as good as the water agent, and the absorption effect after spraying on the leaf surface is not as high as that of the water agent, and the topping work in this patent technology Secondary spraying operation is required, the operation steps are many, the process is complicated, the dosage of chemicals is large, the cost of mechanical spraying is increased, and the spraying of flumethamine also requires high technical requirements for operation

Embodiment Construction

[0018] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0019] The present invention includes three basic operating steps.

[0020] First of all, the basic routine chemical control was carried out by spraying methylpiperon on the leaves from the emergence stage to the boll stage of cotton, and the cultivation measures such as methylpiperon chemical control and water and fertilizer management were carried out according to the routine of local cotton varieties. For overgrown cotton fields, chemical adjustment can be carried out once 5-10 days before chemical topping. On the basis of the local normalized dosage, add 2-3g of mepimonium soluble powder as appropriate for mixed use.

[0021] Secondly, according to the soil in different places, the growth of cotton, and the variety of cotton, as long as the nu...

Abstract

The invention relates to the field of agricultural technology, in particular to a novel chemical cotton topping method for use in a shine early cotton region. The novel chemical cotton topping method comprises the following steps: from the seeding stage to maturation stage of cotton, spraying mepiquat chloride onto leaf surfaces for performing basic conventional chemical control; when the plant heights are 55-65 centimeters and the fruit branch quantity is 6-8 at the cotton maturation stage, spraying a chemical topping aqueous solution onto the top of cotton plants, wherein the chemical topping aqueous solution comprises the following components in parcentage by weight: 15-20 percent of mepiquat chloride soluble powder, 5-10 percent of Tuyouta cotton topping aqueous solution and 70-80 percent of water, and the using amount of the chemical topping aqueous solution is 40-50ml per mu. Through mechanical spraying and topping, the effects of topping and regulating plant growth are achieved, plant growth is inhibited, the labor force and labor intensity are reduced, the topping efficiency is increased, the topping cost is reduced, the yield is increased, and full-mechanical cotton production can be realized instead of manual topping.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a chemical topping method for cotton in early-maturing cotton regions. Background technique [0002] The northern part of Xinjiang belongs to the early-maturing cotton sub-region. The cotton growing season is short, labor shortage, cotton production risks are high, and the requirements for cultivation techniques are high, especially for the level of mechanization. After long-term exploration and practice, cotton mechanization has been basically realized in all aspects of cotton production in this area, from arable land to fertilization, and from sowing to harvesting, except for the cotton topping link that has not been mechanized. The "topping" problem has always been a key link restricting the entire mechanization of cotton in the Corps, and it is also the last link in the mechanization of cotton planting in the Corps. If the topping problem is solved, it will not only sav...
