摘　　要：通过进行棉花专用配方缓控释肥试验示范,明确棉田简化施肥、省工节本的可行性。结果表明,棉花施用专用配方缓控释肥前期长势稳健,中后期生育加快,开花结铃多,能提高产量。施用技术方案为棉苗栽前1周施入棉花专用配方缓控释肥1 500 kg.hm-2,地膜覆盖移栽,打顶后追施尿素75～120 kg.hm-2;花铃期开始,每7～10 d叶面喷施1%～2%尿素溶液+0.2%磷酸二氢钾溶液,喷施3～4次。A trial was conducted by using Ezhamian 25F1 in Qianjiang City to study the effect of low （control）-releasing ex- clusive prescriptive fertilizer （LREPF） on cotton. The results showed that this technology of using LREPF was one new cultivation technique with saving labor, more bolls and high yield compared with the traditional fertilizer. The fertilizing plan of LREPF was under plastic mulching,fertilizing the LREPF 1 500 kg·hm-2 one week before transplanting seedling,urea 75～120 kg·hm-2 after topping,foliage spray with 1%-2% urea solution and 0.2% KH2PO4 every 7～10 days,3～4 times after blossoming and boll forming stage.
