在我市,随着棉花生产的不断发展,棉花生产已由从春到秋的季节性生产逐渐转变为全年性生产。“冬前整好田,来年好种棉,冬闲浇好地,种棉不费力”便是我市棉农生产经验的总结。试验、实践表明,搞好棉田冬耕、冬灌是保证来年棉花优质丰产的基础,其好处为:冬耕。棉农中流传着“深耕加一寸,顶上一茬粪”的说法。棉田冬前深耕,打破了梨底层,加速了生土熟化,使土壤疏松层加厚,水、肥、气、热状况得到调节,改善了土壤结构,增加了土壤内营养物质含量。同时增强了土壤吸水性和渗透性,提高土壤抗旱耐涝能力,能有效地控制盐碱地“积碱返盐”,有利于水分养分吸收, In our city, with the continuous development of cotton production, cotton production has been gradually transformed from the seasonal production from spring to autumn into annual production. “A good winter before the field, a good kind of cotton in the coming year, winter leisure pouring good, cotton is effortless” is the city’s cotton production experience summary. Experiments and practices show that it is the basis for ensuring good winter cotton and winter irrigation in cotton fields in the coming year with the following benefits: winter farming. In the cotton farmers, the saying goes: “cultivating an extra pound of rice and stubble on the top”. Deep plowing cotton fields before winter, breaking the bottom of pear, accelerated the maturation of raw soil, so that loose soil layer thickening, water, fertilizer, gas and heat conditions have been adjusted to improve the soil structure and increase the soil nutrient content. At the same time, it enhances soil water absorption and permeability, improves soil drought resistance and waterlogging resistance ability, and can effectively control “alkali and salt return” in saline-alkali soil, which is beneficial to water nutrient absorption,
