Productive method of Spun-combed 300-yarn organic long staple cotton material

Abstract

The invention relates to a productive method of spun-combed 300-yarn organic long staple cotton material, which includes steps of seed preparation, sowing, irrigating, fertilizer application, topping, field management and the like. Field investigation tests show that diseased plants of suitably-spun combed 300-yarn organic long staple cotton obtained by the production method are rare in the growth period of 146 days, and are highly resistant to wilt and greensickness. In terms of high-yield cotton field group structure, the cotton plants are 85-110cm high, each plant grow 11-13 boll nodes and7.4-10.1 bolls, actually received plants reach 11900-13200 per mu, bolls reach 84300-114700 per mu, the boll setting rate of the middle and the bottom of each plant is high, average boll setting ratereaches 42.4%, each boll weighs 2.7-2.9g, lint percentage reaches 32.1%, seed index reaches 13.5g, lint index reaches 6.7g, pre-frost flowering rate reaches 89.5%, boll opening is intensive and smooth, no cotton falls, cotton picking is easy, fibers are white and glossy, and cotton maturity is high.

Description

technical field [0001] The invention relates to a method for producing organic long-staple cotton raw materials by spinning and combing 300 count cotton yarns. Background technique [0002] Organic cotton can be divided into organic fine-staple cotton and organic long-staple cotton according to fiber type, and organic long-staple cotton suitable for spinning combed 300-count cotton yarn is also a high-quality organic long-staple cotton, and its fiber length requires ≥39mm and specific strength≥ 44cN / tex, micronaire value 3.7, fineness 9.9um, it is a typical organic super high-quality long-staple cotton, because the production of organic cotton does not use chemically synthesized fertilizers, pesticides and growth regulators, and does not use biological engineering The production system of the cultivated varieties and their products is therefore very conducive to the optimization of the agricultural ecological environment. [0003] As countries pay more attention to environm...

AI Technical Summary

Problems solved by technology

[0006] At home and abroad, great attention has been paid to the development of organic long-staple cotton raw materials suitable for spinning combed 300-count cotton yarn. The existing long-staple cotton varieties that have been cultivated adopt the existing conventional organic planting mode. As a result, they cannot meet the requirements of the method for spinning 300-count combed cotton yarn, resulting in raw material production becoming combed 300-count organic long-staple cotton yarn and product development. Obstacles to overcome

[0007] Existing organic fine-staple cotton, even organic ordinary long-staple cotton fertilizer input method can not meet the water and fertilizer requirements of organic super long-staple cotton, such as organic fine-staple cotton or organic ordinary long-staple cotton management methods, organic super long-staple cotton can not Normal growth, manifested as slow growth, especially slow growth at the seedling stage, insufficient boll expansion, and various degrees of "small volume" deformed development state, and obvious adversity forced ripening phenomenon in the later stage, resulting in extremely low yield and low quality. not to standard

[0008] In short, due to the fact that there is neither variety nor operable supporting technology in the production of organic long-staple cotton suitable for spinning 300-count cotton yarn worldwide, the production of organic long-staple cotton suitable for spinning 300-count cotton yarn has failed
