| 摘 要： | 目的]确定江淮丘陵区水稻土小麦合理氮肥施用量。方法]通过田间小区试验,设置施氮（N）量0、60、120、180和240 kg/hm25个处理。小麦成熟期采集25株考种样,测定产量构成性状,并测定每小区籽粒产量。结果]施用适量氮肥对小麦生长发育有明显的促进作用,并能显著增加小麦籽粒产量,提高经济效益。2年试验小麦施氮的增产幅度分别为18.63%-34.09%和15.22%-30.80%,平均增产24.66%和22.32%;最高产量施氮（纯氮）量分别为185.9和189.1 kg/hm2;最佳产量施氮量相应为143.1和133.2 kg/hm2。施氮增收1 571-4 141元/hm2,产投比为2.33-8.68∶1结论]当前生产水平下,江淮丘陵水稻土区,小麦氮肥（纯氮）的适宜施用量为165kg/hm2左右。

| Abstract: | Objective] The aim was to determine the suitable application amount range of nitrogen(N) fertilizer on winter wheat in Jianghuai hilly land of Anhui Province.Method] Five treatments of different N application rates of 0,60,120,180 and 240 kg/hm2 were set up in the test.When the wheat was matured,25 plants were randomly selected in each plot for inspecting the yield components,and seed yield every plot of wheat was observed.Result] The N application could obviously promote the growth of winter wheat,raise... |
