1科学选用品种播前晒种,适时剥壳播种前带壳晒种l～2天,最好在土晒场上晒,以免高温损伤种子。在剥壳前应进行发芽试验,以测定种子的发芽势和发芽率。应在播种前l～2天剥壳,随剥随播,避免过早剥壳使种子吸水受潮、病菌感染或机械损伤。剥壳后应把杂种、秕粒、小粒、破种粒、感染病虫害和有霉变特征的种子拣出,特别要拣出种皮有局部脱落或子叶轻度受损伤的种子。2适时播种应根据品种特性和我县气候变化规律来确定适宜的播期。在适期播种范围内早播,对充分利用有效积温条件提高成果率,具有重要意义。我县
1 species of science before sowing sesame seeds, shell peel timely before planting shelled sun l ~ 2 days, the best sun drying in the soil, so as not to damage the seeds of high temperature. Germination tests should be carried out before pealing to determine the seed germination potential and germination rate. Should be l ~ 2 days before sowing peel, with stripping with sowing, to avoid premature peel moisture soaked seeds, germs infection or mechanical damage. Husks should be hybrids, grains, small grains, broken seeds, pests and mildew infected with the characteristics of the seeds picked, in particular, to pick out the seed coat with partial loss or cotyledons slightly damaged seeds. 2 timely sowing should be based on species characteristics and climate change in our county to determine the appropriate sowing date. Early sowing within the scope of the appropriate sowing date is of great significance to making full use of effective accumulated temperature conditions to improve the yield of fruit. My county
