我所于一九七七年进行了中造水稻水面育秧试验,并与常用的墩子秧作了比较观察。测定的结果是,水面育秧生长较快,一、二、三叶期均比墩子秧提前1-2天;秧苗素质也较好,与墩子秧比,三叶一心期株高增0.5厘米,根长增3.3厘米,根数多1.8条,100株鲜重增4.2克,干重增0.1 5克。在推广一年三造水稻中造秧田难解决的情况下,采用水面育殃有一定的意义。水面育秧在池塘、水沟、江湾等合适的水面进行。播种前选用竹蔓(或尼龙窗纱)做成长3尺、宽2尺的秧托,竹蔓有孔,孔
In 1977, I carried out the experiment of making paddy rice in the water surface and compared it with the commonly used mound seedlings. The results showed that the growth of surface watering seedling was faster and the days one, two and three-leaf stage were all 1-2 days earlier than that of mound seedling. The quality of seedling was also better than that of mound seedling, 3.3 centimeters long, 1.8 more roots, 100 fresh weight by 4.2 grams, dry weight by 0.1 5 grams. In the promotion of three years to make rice in the paddy field difficult to resolve the case, the use of water has a certain significance. Watering seedlings in ponds, ditches, rivers and other suitable water surface. Selection of bamboo before sowing (or nylon screens) to grow 3 feet long, 2 feet wide seedling care, bamboo has holes, holes
