Problems solved by technology

[0007] The present invention aims to propose a method for timely application of defoliation and ripening agents for machine-picked cotton in arid regions, comprehensively coordinates the development status of cotton bolls and the amount of damage to single bolls, and focuses on solving the relatively fixed spraying time of defoliation and ripening agents in the prior art. In order to solve problems such as immature cotton bolls at the top of cotton plants, the application time of defoliation and ripening agent can be flexibly and timely determined according to the boll stage of cotton varieties, so as to avoid the negative impact of defoliation and ripening agent on cotton yield and fiber quality
The timely application of the defoliation and ripening agent method of the present invention can effectively solve the problem of immature cotton bolls at the top of the cotton plant, reduce the damage of the defoliation and ripening agent to the top cotton bolls, and improve the quality of cotton fibers picked by the machine.

Embodiment 1

[0030] A method for timely application of defoliation and ripening agent for machine-picked cotton in arid area, said method comprising:

[0031] S100, autumn plowing and winter irrigation and soil preparation before sowing;

[0032] S200, sowing at the right time and rushing to sow early;

[0033] More specifically, the S200 includes,

[0034] S210. Determine the appropriate sowing date according to the growth period of the cotton variety and the length of the local frost-free period. Early sowing is particularly important. Early sowing can prolong the growth time of cotton and increase the maturity rate of cotton. Preferably, it can be sown according to the stable ground temperature of 5cm at 9.5-17.6°C 3 days before sowing;

[0035] S220, high-density planting and precision sowing, adopts the configuration mode of 66+10+66+10+66+10cm machine-picked cotton; adopts on-demand sowing method on film, precision sowing, 1 seed per hole, 15-30kg per hectare , the number of harve...

Embodiment 2

[0059] Different from embodiment 1, in the present embodiment, the best proportioning of described defoliation ripening agent for the first time is: 80% thiadidiazuron wettable powder 390g / hm 2 With 40% ethephon water agent 1350ml / hm 2 Mixed application. The optimal proportioning of the defoliation and ripening agent described for the second time is: 80% thiadizuron wettable powder and diuron mixture 112g / hm 2 apply.

Embodiment 3

[0061] Different from embodiment 1, in the present embodiment, the best proportioning of described defoliation ripening agent for the first time is: 80% thiadidiazuron wettable powder 360g / hm 2 With 40% ethephon water agent 1000ml / hm 2 Mixed application. The best proportioning of the defoliation and ripening agent described for the second time is: 80% thiadizuron wettable powder and diuron mixture 105g / hm 2 apply.

Abstract

The invention provides a method for timely applying a defoliating and ripening agent to machine-harvested cotton in an arid region. The method for timely applying a defoliating and ripening agent to machine-harvested cotton in an arid region comprises the following steps: S100, ploughing in autumn and irrigating in winter and preparing soil before sowing; S200, sowing at a suitable period and carrying out rapid and early sowing; S300, carrying out timely chemical regulation and control according to seedlings; and S400, timely defoliating and ripening. Compared with the prior art, the method for timely applying a defoliating ripening agent effectively solves a problem that cotton bolls at top parts of cotton plants are immature, reduces damage to the cotton bolls, and improves quality of fibers of machine-harvested cotton.

Description

technical field [0001] The invention relates to the field of cotton cultivation, in particular to a method for timely applying a defoliating ripening agent to machine-picked cotton in arid areas. Background technique [0002] The development of machine-picked cotton is conducive to the realization of large-scale operation, greatly reducing the cost of cotton planting, improving labor productivity, and promoting the rapid development of cotton production methods to modern agriculture. Cotton defoliation and ripening technology is an important prerequisite for the realization of cotton mechanical harvesting. It can not only solve the problem of late maturity of cotton in the late growth period, but also speed up the shedding of leaves before harvest, improve the picking rate and operating efficiency of machine-picked cotton, and reduce the content of machine-picked seed cotton. Miscellaneous rate. [0003] The temperature in the late cotton growth period in Xinjiang cotton ar...
