Problems solved by technology

The practice of large-scale production proves that the current popularized and applied "short dense early" production method is largely incompatible with the current production conditions and technological development, and reform and innovation are urgently needed

Embodiment 1

[0059] according to figure 1 , 2 , 3, 4, it can be seen that a kind of raw cotton production method suitable for wide, early and high-quality cotton in the Northwest inland cotton area, its steps are:

[0060] 1. Seed preparation: According to the "fission" method of breeding, high-quality cotton varieties are bred, such as Zhong 641, a new medium-long-staple high-quality new variety. This variety is a new high-quality medium-long-staple cotton variety bred by distant hybridization and 5-7 years of backcrossing with upland cotton Zhongmiansuo 49 as the female parent and sea-island cotton Xinhai 24 as the male parent. Its growth period is 123 days , boll weight 5.23g, lint content 37.0-39.4%, seed cotton yield 320-350kg / mu, lint cotton 110.0-125.0kg / mu, fiber length 34.6mm, specific strength at break 35.4cN / tex, micronaire value 4.0. The seeds produced in the breeding base are selected through gravity sieving, and the seeds are graded. The third-grade seeds are not used as s...

Abstract

The invention discloses a production method for wide-early-superior raw cotton in a cotton region in Northwest China. The method includes the following steps of 1, fission type elite seed production,wherein variety selection,10-ten-thousand-times fission type seed reproduction, and grain selection according to the grain size are conducted; 2, planting in rows with the equal width and conducting the following matching technologies: the variety selection and rational early sowing technology, the edge film widening and lighting technology, the sowing row no-covering-soil and film no-covering-soil technology, the appropriate seedling water dropping technology, the first water late-drop technology, the plant-height increasing and appropriate tip pruning delay technology, and the cotton-flowering and boll-forming fertilizer re-application technology; 3, an early-sowing and early-ripening matching technology; 4, superior raw cotton quality control technologies which includes the technology of uncovering mulching films in the optimum period and preventing pollution, the technology of spraying an appropriate amount of disleave agent and ripener in the appropriate period, the technology ofremoving field weeds and foreign matters and the technology of harvesting in the appropriate period. The method is feasible, operation is simple and convenient, conversion from short-dense-early 'getting cotton by temperature' to tapping of the potential of light, temperature and environment resources is achieved, and support is provided for high-yield, high-efficiency and high-quality cotton.

Description

technical field [0001] The invention belongs to the technical field of cotton planting, and more specifically relates to a raw cotton production method suitable for wide, early and high-quality cotton in inland cotton areas in northwest China, and suitable for cotton production areas with medium fertility and above, drip irrigation or furrow irrigation conditions in inland cotton areas in northwest China. Background technique [0002] The Northwest inland cotton region is the main cotton producing area in my country. In recent years, the cotton area and output accounted for more than 60% of the national total. In 2016, the cotton-planting area in the inland Xinjiang cotton area reached 1,805,200 hectares (27,078,000 mu, 667m 2 per mu), with a total output of 3.594 million tons of lint, accounting for 53.5% and 67.3% of the national total respectively. However, the quality of cotton in the Xinjiang cotton area in the northwest inland is gradually deteriorating. According to...
