摘　　要：以水稻品种空育131为材料,采用小区对比试验方法,研究日式钵育秧盘对寒地水稻植株形态特征和产量形成因子的影响,以探明其对水稻生长和产量的影响。结果表明:水稻应用日式钵育秧盘是通过增加每穴穗数、每穗着粒数和千粒重来提高产量。并在抽穗期,增加了LAI、有效叶面积率和叶片长、宽等指标促进干物质积累。Effects of Japanese seedling-growing tray on rice morphological characteristics and grain yield components were studied with ＂Kongyu 131＂ as materia by plot comparative test in cold area,to determine the effects of growth and yield in rice. The results showed that it were increased the panicles per plant, the grain number per panicle and 1000 mix grain weight of Japanese seedling-growing tray treatment, to increase grain yield. And it were increased LAI, effective leaf area rate, leaves length and width, and so on,to promote dry matter accumulation.
