从我县种植苜蓿四年的经验和教训中我们感到要人工种植好紫花苜蓿,必须把握住三个主要环节: 一、播前整地锄草我县草籽场大都是新开垦的生荒地,三年来,他们都撑握住五月下旬翻地,随即耙地,达到平整细碎无大块,以防止土壤水分大量散失,以利于弱小的芽子拱出土来。播前除草也十分重要。79年该场由于赶期播种,忽略了播前除草,结果草苗齐发,各类杂草严重欺苗,以至草荒成了这一年种草失败的原因之一。之后,他们都在播前用园耙除草一、二次,苗期管理只用少量工拔除零星的高草或蒿子,较好地杜绝了草荒。
From four years of experience in planting alfalfa in our county and our lesson, we feel that we must planted alfalfa by hand. We must grasp three main aspects: First, sowing weeds before sowing Grassland in our county is mostly a newly reclaimed heath. In recent years, they all hold the ground in late May, and then rake, to reach the formation of fine pieces without chunks to prevent the loss of a large number of soil moisture, in order to facilitate the emergence of a small bud out of buds. Weeding before sowing is also very important. 79 years due to the planting of the field, ignoring the weeding before sowing, the results of seedlings Qi, all kinds of weeds serious bullying, as well as grassland became one of the reasons grass failure this year. Afterwards, they all used the garden rake to weed the grass one or two times prior to sowing. Only a small amount of labor was needed to remove the sporadic grass or artemisia seedling in the seedling management, so as to eliminate the shortage of grass.
