尼龙育苗具有早育苗、早插秧、苗全、苗壮、省工、省秧等特点,可以延长水稻有效生长期,提高产量。作者就尼龙育苗的选地、作床、种子处理、夹防风障、播期、播量、复盖方法、幼苗鍛炼、苗地施肥等技术問題作了分析,指出尼龙育苗的成敗关鍵在于复盖期間的管理,提出在播后至出苗前应以保温为主,幼苗出土后应控制床温不超过35℃,午前十时左右沟灌,午后四时后撤水,揭布前5—6天作好幼苗鍛炼,揭布后保持水层及追肥等初步經驗。
Nylon seedling with early nursery, early planting seedlings, Miao Zhuang, Miao Zhuang, provincial workers, provincial seedlings and other characteristics, can extend the effective growth period of rice and increase production. The author made an analysis on the technical problems of nylon seedling selection, bedding, seed treatment, windbreak protection, sowing date, sowing quantity, covering method, seedling training and fertilization of seedling land. The key point of the success of nylon seedling breeding lies in Cover during the management, proposed in the post-sowing to pre-emergence should be based insulation, seedlings should be controlled after the outbreak of the bed temperature does not exceed 35 ℃, around 10 o’clock in the afternoon ditch irrigation, water after the withdrawal of four o’clock in the afternoon, before the release 5-6 Make seedling training days, to expose the water layer and top-dressing and other initial experience.
