| 摘 要： | 研究了栽培密度对水稻中优281产量性状的影响,结果表明:栽培密度与群体有效穗呈极显著正相关,与穴有效穗、穗总粒数、穗实粒数、穗长、结实率及千粒重均呈极显著负相关;相关产量性状间,穴有效穗与群体有效穗呈显著性负相关,穗总粒数与穗实粒数呈极显著正相关,而与穗长则呈显著正相关;其最适栽培密度是20.0 cm × 23.3 cm.

| Abstract: | Effect of planting density on characters of yield of rice Zhongyou 281 was studied in this paper.The results showed that planting density was significantly positively correlated with group effective panicles,and significantly negative correlation with hole effective panicles,total grains per panicle,practical grains per panicle,panicle length,seed setting rate and thousand seed weight.There was a significantly negative correlation between hole effective panicles and group effective panicles;a significant po... |
