1.备足种子.选用无病、纯度高、发芽势85%以上、发芽率在95%以上的种子.每盘播干种90～100克.采用9×3寸的插秧形式,每亩需30盘秧苗,需干种6斤.3月中旬,选背风向阳处,抓住晴天中午晒种3～4天,可提高种子发芽势和发芽率.2.种子除芒.种子除芒,不仅能显著地提高播种质量,而且能加快吸水速度和萌动破胸.一台除芒器作业8小时可处理1,200～1,300斤种子, 1. Sufficient seeds. Selection of disease-free, high purity, germination potential of 85% or more, the germination rate of 95% or more of the seeds. Drying per panpan 90 to 100 grams. Using 9 × 3-inch transplanting form, 30 tray seedlings, need dry species 6 kg mid-March, the leeward sunny place, seize sunny at noon basal 3 to 4 days, can improve the seed germination potential and germination rate .2 seeds in addition to the seed seed removal, not only Can significantly improve the quality of seeding, but also to speed up the rate of water absorption and sprouting broken chest.Master removal of 8 hours can handle 1,200 ~ 1,300 pounds of seeds,
