| 摘 要： | 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了田间试验,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,推荐了合适的小麦施肥量为N(-) 130～210 kg/hm2、P2O540～70 kg/hm2、钾K2O 40～60 kg/hm2. |

| Abstract: | ’3414’ field experiment(nitrogen,phosphorus and potassium as 3 nutrient elements,4 gradient of each element,a total of 14 unrepeated incomplete treatments were designed to study the fertilization techniques for wheat interplanted with cotton in Qianjiang city,Hubei province.Fertilizer model for wheat interplanted with cotton in Jianghan plain was established,based on which the soil nutrient plentiful-lack index in wheat-cotton interplanting field in the district,correction value for the application value of nitrogen,phosphorus and potassium for wheat were put forward.Appropriate application dose of N,P2O5 and K2O were recommended as 130～210,40～70 and 40～60 kg/hm2,respectively. |
