| 摘 要： | 目的]为合理利用秸秆资源提供理论依据。方法]以不同水稻和油菜品种为材料,不施秸秆为对照,研究无水层灌溉栽培和常规淹水栽培条件下连续多年秸秆还田对水稻及后茬油菜产量的影响。结果]常规淹水栽培条件下,小麦秆与土壤混合、油菜秆与土壤混合处理第1年水稻产量较对照增加5.9%～7.2%,第2、3、4年水稻产量分别较对照减少6.7%～8.0%、16.0%～17.9%、22.6%～23.9%;无水层灌溉栽培条件下,秸秆还田处理第1年水稻产量较对照增加6.3%～11.5%,第2、3、4年水稻产量分别较对照减少0～21.3%、2.1%～2.8%、9.6%～11.6%;秸秆还田处理第1年油菜产量较对照增加1.8%～9.3%,第2、3年油菜产量分别较对照增加4.3%～10.6%、5.9%～14.1%。结论]秸秆还田后第1年水稻产量增加,连续多年秸秆还田后油菜产量逐年增加。

| Abstract: | Objective] The study was to provide the theoretical basis for rational utilization of straw resources.Method] With different rice and rape varieties as the materials and the treatment without straw application as CK,the effects of straw returning for successive years on yields of rice and succeeding rape under the conditions of none-water layer irrigation cultivation and conventional flooded cultivation were studied.Result] Under conventional flooded cultivation condition,rice yields in treatments of whe... |
