Cutting was not beneficial to tiller, all cutting treatments did not exist compensatory growth effect of tiller.
刈割不利于多年生黑麦草的分蘖，所有刈割处理均不存在分蘖的“超补偿生长”效应；Secondly, the population density decreased with increasing of defoliation intensity, but the difference is not significantly.
其次，种群密度随着刈割强度增大而降低，但处理间的差异不显著；In all treatments, mowing and covering and returning the livestock's feces to the orchard had the best ecological benefits.
不同土壤管理方式的生态效益以刈割覆盖和畜粪还园处理最好。Along with the postpone of harvesting time, the reductive sugar content and total sugar content showed a decreasing tendency.
随首次刈割时期推后，两种牧草的还原糖和总糖含量均呈逐渐减小趋势。The population characteristics varied with the increasing of cutting intensities.
羊草种群特征随刈割强度增大发生不同程度的变化。Therefore, after the frost must not mowing, should take active scientific measures to make the losses caused by disasters to a minimum.
因此，霜冻后不要刈割，应积极采取科学的管理措施，把灾害造成的损失降到最低。In this study, annual Ryegrass named diamond T was selected and a series of research including fertilization and cutting were carried out.
本试验主要以贵州黔南地区的钻石T多花黑麦草为对象进行了施肥和刈割两方面深入的试验。When harvested three times in one year, up-ground biomasses were closely related with water consumption.
年刈割三茬，地上生物量与苜蓿耗水量密切相关；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。
