野生山蚂蝗绿肥对酸性土壤有机质含量的动态影响
|
摘要
山蚂蝗属(Desmodium Desv.)植物是我国南方重要的绿肥资源,为探明其培肥效果,本文通过田间试验研究了施用12份野生山蚂蝗属绿肥后,酸性土壤有机质含量随时间的动态变化,结果表明:不同山蚂蝗属绿肥对土壤有机质含量影响的效果不一,在施用1年内均能显著(p<0.05)增加土壤有机质的含量,且施用1个月后效果最好,但随着时间的延长效果不断变差。
Desmodium was an important green manure(GM)resource in Southern China,twelve wild Desmodium plant germplasms were used to research the acid soil organic matter(SOM)content dynamics with the application time by using the field trial.The results indicated that the application of Desmodium GM all could increase the SOM content significantly(p<0.05)after one-year application,and the best effect appeared in the period one month after application,but the effect was weaker and weaker with the prolongation of time after application.
