High-yield cultivation method of crop rotation of sea island cottons with long and short fruit branches

Abstract

The invention discloses a high-yield cultivation method of crop rotation of sea island cottons with long and short fruit branches, which comprises the following steps of: autumn tillage and winter irrigation, fine land preparation, preparation of suitable varieties, field planting mode, scientific field management and timely harvesting; according to the method, the long fruit branch sea island cotton and the short fruit branch sea island cotton are planted in an intercropping way, so that the marginal effect of the long fruit branch sea island cotton can be increased, the utilization rate of space resources is effectively improved, and the economic benefit is greatly improved; the method mainly adopts the currently commonly used planting mode of machine-picked cotton in Xinjiang, one filmcorresponds four rows, one film of long fruit branch loose plant type sea island cotton is adjacent with two films of short fruit branch compact plant type sea island cotton and one film of long fruitbranch sea island cotton, the arrangement is repeated in this way, the arrangement of crops in the field is optimized, the planting layout of the plant type structure alternate arrangement of loose-compact-loose is integrally formed, no significant difference exists in the quality of the sea island cotton fiber, but the yield of seed cotton and lint cotton can be increased by 10.07% and 10.95% respectively, and the yield and benefit of cotton per unit area can be obviously improved.

Description

technical field [0001] The invention relates to the technical field of cotton planting and cultivation, in particular to a high-yield cultivation method for sea-island cotton with long and short fruit branches in rotation. Background technique [0002] Sea-island cotton (Gossypium barbadense L.) is one of the two main tetraploid cultivars of cotton, and has become one of the most valuable cotton cultivars because of its excellent fiber quality and disease resistance. At present, sea island cotton is planted in a certain area in Egypt, Sudan, Uzbekistan and other countries, and it is planted in a large area in the southern Xinjiang of my country. With its unique climate conditions, Xinjiang is currently the only sea-island cotton production base in China, which has made outstanding contributions to my country's high-quality cotton production. Xinjiang is currently the only sea-island cotton planting and production base in China. The most serious problem facing Xinjiang sea-i...
