【摘要】 本文对水稻泥中水直播防倒技术进行了研究,通过两年来的盆裁试验,取得以下结果:①经过增氧剂除敷的稻种,确有促进幼苗长根的效果;②增氧剂中各成份比例,以过氧化钙占35%,熟石膏占65%的较合适,稻种上的增氧剂剥落少,发芽和幼苗生长均较好;③除了关键性的粘合剂熟石膏外,在涂敷增氧剂前,还必须把稻种放在粘附剂中浸一下,则能把要求涂敷增氧剂的数量,全部地均匀地涂敷在稻种上,粘附剂以比重1.03的胶水和比重为1.26的糖水为佳;④经过涂敷的稻种,播种深度以1厘米左右为宜。更多还原

【Abstract】 This paper presents a technique of lodging resistant for rice sowing direct in flooded paddy field.For more than two years potted plant test the results are as follows. 1.Smearing the seeds with oxygen release agent can made the roots of seed- ling fix well in soil. 2.The oxygen release agent which consist of 35% calcium peroxide and 65% plaster will produces higher adhereing effect and presents better badding and seedling growing. 3.The seeds should be soaked in solution of adhere agent before their smearing so that they can get enough oxygen release agent and be smeared evenly. 4.The depth of sowing should be controlled about 1cm.更多还原
