| 摘 要： | 通过田间小区试验研究了秸秆还田对水稻产量和土壤肥力的影响。结果表明:与常规施肥比较,秸秆还田可以显著提高水稻籽粒产量,秸秆半量还田和全量还田分别增产12.4%和17.9%。秸秆还田可以提高土壤有机质和速效钾含量,秸秆半量还田和全量还田处理有机质分别提高了1.2 g/kg和2.1 g/kg,速效钾分别提高了16.5 mg/kg和24.7 mg/kg。

| Abstract: | A field plots experiment was conducted to study the effects of crop straw on rice yield and soil fertility. The results showed that compared with the conventional fertilization treatment, the returned crop straw could significantly increase the grain yield of the rice,the grain yields of the rice increased by 12.4% and 17.9% with the half and the total amount of the straw returned to field respectively. Reused straw could increase the soil organic matter and available potassium content. The organic matter increased by 1.2 mg/kg and 2.1 g/kg,the available potassium increased by 16.5mg/kg and 24.7 mg/kg with the half and the total amount of straw returned to field respectively. |
