The herbage coverage was affected by arbor coverage. 草本盖度主要受乔木盖度的影响;
And by devouring the herbage which might have maintained millions of sheep and cattle. 它们在地下打洞,吃掉本可以饲养数百万头牛羊的牧草。
Nitrogen manuring is essential to get a good yield of cut herbage. 为了获得刈割牧草良好的产量,使用氮肥是极为重要的。
The litter was more affected by arbor, shrub and herbage coverage, but less affected by topography factor. 枯落物受乔灌草盖度影响较大,受地形类因子影响较小;

Interspecific Relationships among the Herbage Species of Abandoned Farmlands alongside Jinshui River in the Qinling Mountains 秦岭金水河岸弃耕地草本植物种间关系
The comparative test of twenty one species of perennial grass introduced into alpine cold pasture showed that in herbage yield and winter hardiness. 青藏高原高寒地区,多年生禾草混播草地是提高草地生产力、维护草地生态平衡的集约化牧业用地的最佳选择。
Therefore, the herbage vegetation is more sensitive to precipitation than the shrub in desert-oasis. 因而草本植被对降水的敏感性大于灌木。
It shows that if the rainfall increased in the autumn, the storage of the soil water was higher next spring, moreover the better the soil moisture, and the earlier the regreening, and the higher herbage yield of the natural grassland. 分析表明:秋季降水越多,环湖区土壤水分贮存量越多,翌年土壤墒情越好、牧草返青越早且牧草产量越高。
