| 摘 要： | 为改进干秸秆还土见效慢的不足,采用田间小区试验的方法,在贵州省黔西县进行了绿肥与秸秆混合还土的效果试验。结果表明:在垄作、规范化种植的基础上绿肥与秸秆混合施用玉米增产效果明显,粗蛋白含量明显提高,土壤有机质、全量氮、磷、钾比对照土壤略有增加,土壤pH、有效磷略有增加。综合考虑,初步认为绿肥与秸秆混合施用是比单一秸秆还土更好的秸秆还土技术。

| Abstract: | The plot design was conducted to investigate effects of green manure and maize straw on maize yield,maize crude protein and soil fertility in Qianxi county,Guizhou.The results showed that mixedly applying green manure and maize straw could obviously increase maize yield and maize crude protein content,and slightly increase the content of soil organic matter,total N,P and K,pH value,and effective P compared with CK on the basic of the ridge culture and standard cultivation.The authors consider that the effects of mixedly applying green manure and maize straw is better than singularity applying maize straw on maize yield,maize crude protein and soil fertility. |
