摘要
试验表明,不同的羊草利用强度对土壤肥力有不同的影响,羊草留茬高度与土壤肥力的相关性并不是完全的正相关关系;但本研究中羊草只经过1 a的生长,故各处理的土壤肥力差异不太明显。
The results of field experiment showed ： The different treatments to the grass had different effects on soil fertility. The difference in fertility between the different treatments were not direct ratio to the height of the grass, and on the other hand these differences in the experiment was not prominent due to the one-year treatment was relatively short.
