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.
