Thin-planting early-maturing high-quality cultivation method for cotton

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a method for cultivating cotton with sparse planting, early maturity and high quality. Background technique [0002] Cotton is the seed fiber of the Malvaceae cotton plant, native to the subtropical zone. The plant is shrubby, and can grow up to 6 meters high in tropical areas, generally 1 to 2 meters. The flowers are milky white, turn dark red soon after flowering and then wither, leaving small green capsules called cotton bolls, which contain cotton seeds , the fluff on the cottonseed grows from the skin of the cottonseed and fills the inside of the cotton boll. When the cotton boll matures, it splits to reveal soft fibers. The fibers are white or white with yellow, about 2 to 4 cm (0.75 to 1.5 inches) long, containing fibers Vegetables are about 87-90%, water 5-8%, and other substances 4-6%. [0003] On the market, it is inconvenient to plant cotton arbitrarily acco...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of cotton thin-planting early-maturing high-quality cultivation method, to solve the inconvenience proposed in the above-mentioned background technology, plant cotton randomly according to local conditions, and roughly prevent diseases and insect pests, resulting in low cotton yield and few bolls per plant , single boll is light and low, stress resistance and adaptability are low, and secondly, it is inconvenient to increase the active soil layer, which is not conducive to microbial activities, resulting in weak fertilizer retention capacity and other shortcomings
