通过羊群宿营建植改良草地的研究

A Study on Establishment of Improved Pasture through Sheep Camping

本文报道了在贵州高原山地条件下通过绵羊夜间宿营的方法建植改良草地的研究。结果表明，羊群宿营不仅能较彻底地清除原有饲用价值不高的植被，而且大幅度提高土壤养分含量，从而使播种的优良牧草得以成功建植。鸭茅、黑麦草和白三叶均为改良草地的宜植草种，而其中尤以鸭茅为最适禾草。7．2羊·夜／m2的宿营载畜率具有最佳草地建植效果。

A field experiment was conducted to study the establishment of improved pasture by means of sheep night penning at the unimproved camping site on a hill country farm in Guizhou Plateau area. The results showed remarkedly increased soil fertility, good clearance of the native vegetation which is of very low feeding value, and successful establishment of the oversown species. As a result of comparison, ryegrass,cocks foot and white clover all proved to be right species for oversowing on the camping area, with cocksfoot being of the best performance. It was evidently observed that a stocking rate of 7. 2 sheep nights per square meter is required for successful pasture establishment by this technique.
