棉田化肥基施是盐城地区棉花苗期施肥技术的一项改革。1979年开始多点试验示范,化肥基施的面积28,000亩;1980年大面积推广为35万亩;1981年发展到87万亩;1982年又继续扩大为151.4万亩,占全区直播棉田面积270万亩的56%。四年的实践证明,棉田化肥基施能替代黄芽肥、三叶肥(花芽原基分化肥)的使用效果,促进棉苗健壮早发,增强抗逆能力,提早现蕾期,特别是促进粮棉套种中的边行棉花前期快长 Cotton base fertilizer is Yancheng area cotton seedling fertilizer technology a reform. More experiments and demonstrations started in 1979, with an area of ​​28,000 mu of chemical fertilizers; a large-scale popularization of 35 million mu in 1980; an increase of 87 million mu in 1981; an increase of 1,514,000 mu in 1982, 56% of 270 mu. Four years of practice have proved that cotton-based chemical fertilizers can replace the use of yellow bud fertilizer and clover fertilizer (flower bud primordia) in promoting the robust early emergence of cotton seedlings, enhancing the resilience and early budding stage, and especially promoting The cotton in the cotton-cotton intercropping line is growing faster in the earlier period
