| 摘 要： | 采用田间小区定位试验研究自然降雨条件下稻秸全量还田对稻麦两熟农田麦季养分径流流失特征的影响。结果表明：麦季径流水量可达2 185.05 m^3/hm^2,秸秆还田（T1）处理可降低径流水量4.43%（p〉0.05）;常规施肥（T0）条件下,每1 hm2麦田径流流失全N（TN）和全P（TP）总量分别为30.90,3.00 kg,流失率分别达13.73%和3.34%;较T0处理而言,T1、T2（秸秆还田减肥）处理不仅减少TN和TP流失量分别达15.95%,33.50%和13.98%,15.71%（p〈0.05）,也能降低TN流失率分别达15.95%,16.87%（p〈0.05）。同时,T1处理能够显著降低TP流失率达13.98%（p〈0.05）。

| Abstract: | Field plot experiment was carried out to study the effects of rice straw return on surface runoff of nutrients losses during the wheat growing season of intensive rice-wheat double-cropping season under natural rainfall conditions.The results showed that the total volume of surface runoff water reached 2 185.05 m3/hm2 during the whole wheat growing season,rice straw application(T1) decreased by 4.43% of the volume of surface runoff water,compared with the conventional fertilization(T0) treatment(p>0.05);Und... |
