研究施用8种野百合属绿肥后砖红壤速效钾含量随时间的动态变化。结果表明,施用不同的绿肥对土壤速效钾含量的影响不同,但对土壤速效钾含量影响的基本规律一致。施用绿肥后的不同时间内能不同程度的提高土壤速效钾的含量,提高幅度最大的为埋田一个月,且施用绿肥后的土壤速效钾含量显著高于对照(不施用绿肥的土壤)。
The dynamic changes of available potassium in brick red soil after 8 kinds of wild lily green manure were studied. The results showed that different application of green manure had different effects on available K, but the same as the basic rules of affecting soil available K. After application of green manure in different time to varying degrees of soil available potassium content, the largest increase for buried land for a month, and after application of green manure soil available potassium was significantly higher than the control (no green manure soil).
