为了有效防除人工草地中的杂草,试验在春秋两季种植的刈割型紫花苜蓿草地中将杂草与人工牧草一同刈割饲喂畜禽,测定了牧草产量和杂草变化情况。结果表明:秋播人工草地里的杂草少于春播人工草地;刈割对防除杂草效果明显,3次刈割后人工草地中杂草比例下降到1%以下,基本达到了消除杂草的目的。
In order to effectively control weeds in artificial grassland, weeds were weeded with artificial grazing on mowed alfalfa grasslands planted in spring and autumn to test the changes of pasture production and weeds. The results showed that weeds in autumn sowing artificial grassland were less than those in spring sowing artificial grassland. Cutting effect on weed control was obvious. The proportion of weeds in artificial grassland decreased to less than 1% after three mowing and basically reached the goal of eliminating weeds purpose.
