摘要： 本文研究了焚烧对芨芨草生产力的影响。焚烧后芨芨草在开花期可增产62.2%,其营养价值在生长前期有所提高,以粗蛋白质与灰分含量的提高和无氮浸出物与纤维素的降低为特征。烧后芨芨草生育期可延长15天左右,叶量增大,地上部增重大于地下部。

Abstract: In this experiment, the authors studied the effect of buming on the yield and quality of Achnatherum splendens.The results show as follows: the yield increased by 62.2% in theflowing stage, protein and ash content increased obrionsly, N-free extract and cellulose contentdecreased slightly from burned than those of unburned.The growing stages lasted about 15 days,quantity of leaf increased from burned than those of unburned.The effects of burning was heavyon above-ground than under-grownd.
