加强种株的栽后管理是获得萝卜种子高产的一项有效措施。管与不管,结果迥异。据调查,精细管理者可增产23～56％、种子千粒重也显著提高。现将主要栽培管理技术介绍如后。一、分期追肥追肥可促进种株营养生长,促进分枝,增加荚果,从而提高种子单产,提高千粒重。对于个体较小的种株尤为重要。种株生长期间一般追肥3次。第一次在栽植成活后,要及时追施缓苗肥,利用冬前气温较高的条件,促使种株迅速
Strengthening plant management after planting is an effective measure to obtain high yield of radish seeds. Regardless of the tube and the result is very different. According to the survey, fine managers can increase 23 ~ 56%, the seed weight was also significantly increased. The main cultivation and management techniques are introduced as follows. First, staging top dressing fertilizer can promote seedling vegetative growth, promote branching, increase pod, thereby improving seed yield and improve 1000-grain weight. This is especially important for smaller individuals. Plant growth during the top dressing 3 times. After planting for the first time, it is necessary to promptly recuperate the slow-growing seedling fertilizer and make use of the conditions of high temperature before winter to prompt the rapid plant growth
