South Xinjiang cotton high-quality high-yield planting method

Abstract

The invention discloses a south Xinjiang cotton high-quality high-yield planting method. Compared with the prior art, the flowering rate of the method can reach 100% before frost, the average length and the fracture strength of the upper half of fibers of the method is increased by 0.8-1.2 mm and about 0.8 cN / tex respectively in comparison with that of the conventional method; the single boll weight is increased by 0.5-0.7 g; and the seed cotton yield is increased by 10-15% in comparison with that of the conventional method. Cotton field population and individual structure is optimized, water and fertilizer management is optimized, the number of bolls of a single plant and the single boll weight are increased, the flower rate is decreased after frost, and then the yield of cotton can be increased, the high quality of an original variety of the cotton can be ensured, and the south Xinjiang cotton high-quality high-yield planting method has promotion and use value.

Description

technical field [0001] The invention relates to a method for planting cotton, in particular to a method for planting high-quality and high-yield cotton in southern Xinjiang. Background technique [0002] Most of the existing cotton planting in southern Xinjiang adopts under-mulch drip irrigation. There are reasons such as excessive theoretical density, large number of retained fruit branches, poor fertilizer allocation, and irrigation time and frequency that are difficult to meet the needs of cotton during the growth period. Individual advantages cannot be brought into full play, resulting in few bolls per plant, light weight per boll, many flowers after frost, low yield and poor quality. Contents of the invention [0003] The object of the present invention is just to provide a kind of high-quality and high-yield planting method of cotton in southern Xinjiang in order to solve the above problems. [0004] The present invention achieves the above object through the follow...
