| 摘 要： | 土壤养分与春小麦产量关系及最佳施肥量研究结果表明 ,春小麦产量与土壤养分关系十分密切 ,尤其与土壤有机质、碱解氮含量相关性较好 ,而与速效磷和速效钾关系较差 ;土壤养分供N量严重不足、部分缺P但富K ,这与产量 养分敏感性分析结论相一致 ;春小麦最佳施N量较常规减少 10 % ,施P量减少 15 %。

| Abstract: | The relationship between soil nutrient and spring wheat yield and optimum fertilization are studied. The results show that the yield and soil nutrient have a close relationship, especially the nutrients of soil organic and Hydrolysis N,but the effects of available P and available K are not very significant. There is a lack of N in particular, P in partial and K is very rich in soil. These results are in a good fit with the yield-nutrient sensitivity. The optimum fertilization of N is cut down 10% than normal,P is cut down 15%. |
