水育秧和水直播苗期均有烂芽和烂秧的问题,早在60年代初便研究清楚了缺氧是其主导原因。生产上解决缺氧的办法是出芽后的落干,但并不能彻底解决,因而保苗、壮苗是水育秧和水直播的急待研究和解决的问题。用氧化剂过氧化钙作为苗期氧源,日本已进入应用阶段,我国还未报导此方面的研究。1984年6月北京农业大学应用化学研究所试制了少量的过氧化钙样品,由农学系水稻
Watering seedlings and water-seeded seedlings have rotten buds and rotten seedling problems, as early as the early 60’s it was clear that hypoxia is the leading cause. The solution to the problem of hypoxia in the production is to dry out after budding, but it can not be completely solved. Therefore, seedling-raising and seedling-raising are urgent research and solutions to water-saving seedlings and water-borne plants. Oxidant calcium peroxide as a seedling oxygen source, Japan has entered the application stage, our country has not reported this research. 1984 June Beijing Agricultural University Institute of Applied Chemistry pilot trial of a small amount of calcium peroxide samples by the Department of Agronomy rice
