The invention discloses a thin-planting early-maturing high-quality cultivation method for cotton, and relates to the technical field of
crop cultivation. The thin-planting early-maturing high-qualitycultivation method for the cotton comprises 240-250 kg of seed cotton and 95-100 kg of ginned cotton, the yield structure is 1500-1600 plants / 667m<2>, bolls per
plant is 30-32, the single boll weightis more than 5 g, the lint percent is more than 40%, the
fiber length is greater than or equal to 30 mm, the
fiber breaking tenacity is greater than or equal to 30 cN / tex, the micronaire value is less than or equal to 5.0, and the growth period is less than or equal to 110d. The thin-planting early-maturing high-quality cultivation method for the cotton can cultivate strong seedlings, the hybridadvantage is strong, the yield-increasing potential is large, the single boll number is large, the single boll weight is high, the
stress resistance and the adaptability are high, soil
moisture conservation,
drought resistance, water drainage, wind resistance and lodging resistance enhancement are facilitated, inter-row ventilation is facilitated, and boll rotting is reduced; and cotton
topping isconducted at
proper time, so that the
apical dominance and the
plant height are controllable, invalid flower buds are avoided,
nutrient consumption is reduced, squaring bolls on the lower middle portion and the inner periphery can obtain sufficient nutrients, the boll forming rate and the boll weight are increased, the yield of flowers before
frost is increased, and meanwhile due to sufficient
nutrient supply in the boll forming period, the quality of cotton fibers can be remarkably improved.
