芝麻是种子较小的双子叶植物,幼芽顶土力弱,播种时因各种因素影响,往往不能一次全苗.为探索有效的补救措施,我们作了补种及不同生长期移栽试验.现初步总结如下.试验地选择缺苗的一般大田地块,品种是驻芝四号,对缺苗的分别采用补种和四叶期、六叶期、现蕾期移栽,以适时出苗的为对照,重复三次,每次处理100株,随机取样10株进行室内考种.从几种不同方式补苗情况看.补种的芝麻一般晚出土6～8天.前期生长弱,后期急速生长,形成腿高,稍子长,千粒重及单株粒重显著下降.以六叶期移栽的植株经济性状较好,单株蒴果比补种的多112.3个,比四叶期移栽的多12.5个,比现蕾期移栽
Sesame seed is a dicotyledon with a small seedling top soil strength is weak, often due to various factors when sowing, can not be a full seedling .In order to explore effective remedial measures, we made a variety of replanting and different growth stages of transplanting test .Preliminary summary is as follows.Piloting the selection of the lack of seedlings general field plots, the variety is in the Chi on the 4th, the lack of seedlings were re-used and four-leaf stage, six-leaf stage, budding stage transplanting to timely emergence Of the control, repeated three times, each treatment of 100, a random sample of 10 indoor test species from several different ways to see Miao Miao situation.Recommended sesame generally late unearthed 6 to 8 days .Premature growth is weak, the latter rapid growth , Forming leg height, slightly longer length, 1000-grain weight and grain weight per plant significantly decreased.The economic traits of plants transplanted in six-leaf stage were better, bolls per plant were 112.3 more than those in four-leaf transplanting 12.5, transplanting than budding period
