在水稻制种上,抛秧移植新技术是水稻制种技术的一项创新和改革,大邑县杂交水稻制种在1998年、1999年大面积推广母本抛秧栽培技术。2a 来的抛秧实践中,我们发现抛秧基本苗应比栽插基本苗增加。为了进一步完善该项技术,量化指标,1999年在本县敦义乡西安村进行了抛秧基本苗控制试验。1 材料与方法1.1 试验田基本情况试验田是川西平原黄壤土,肥力中等。地点在敦义乡西安村l社,户主:杨玉清,面积667m~2,前作小麦。1.2 试验材料
In rice seed production, throwing transplanting new technology is an innovation and reform of rice seed production technology, Dayi County, hybrid rice seed production in 1998, 1999, popularizing the mother-plant cultivation techniques to promote a large area. 2a to the throwing seedling practice, we found that throwing seedlings planted seedlings should be increased compared with the basic seedlings. In order to further improve the technology, quantitative indicators, in 1999, the village of Dongnian Township, Dongniao Throwing seedlings control experiments. 1 Materials and methods 1.1 Experimental field of the basic situation Experimental field is the plain of western Sichuan yellow loam soil, medium fertility. Location in the village of Xi’an Village, Dunyi Township, head: Yang Yuqing, an area of 667m ~ 2, before the wheat. 1.2 Test Materials
