摘　　要：3414 field experiment （including three nutrient elements at four gradient levels, a total of 14 unrepeated incomplete treatments） was designed to study the fertilization measures for wheat interplanted with cotton in Qianjiang City, Hubei Province. Fertilizer model for wheat interplanted with cotton in Jianghan Plain was finally established, based on which the soil nutrient indices in wheat-cotton inter- planting field were screened; and optimal nitrogen, phosphorus and potassium appli- cation for wheat was put forward as 130-210 kg/hm2 N, 40-70 kg/hm2 P2O5 and 40-60 kg/hm2 K2O.该研究采用氮、磷、钾3个养分因子．每个因子分4个施用梯度．共14个处理的无重复不完全大田试验设计”3414”方案．对湖北省潜江市棉麦套种方式下的小麦施肥技术进行田间试验，建立了江汉平原棉麦套种方式下小麦的施肥模型，并在此基础上．提出了区域棉麦套种区土壤养分丰缺指标与小麦氮、磷、钾施用量的修正值．结果表明合适的小麦施肥量为130-210kg/hm2 N，40～70kg/hm2P2O5,40-60kg/hm2K2O.
