不同栽插密度对南粳9108群体性状及产量的影响
Effects of Different Planting Densities on Population Characteristics and Yield of Nanjing 9108
摘要
Abstract
Effects of different machine inserted row spacing(20 cm, 25 cm and 30 cm) on population characteristics and yield of late maturity japonica rice Nanjing 9108 were investigated. The results show that tiller number, leaf area index and dry weight of rice with machine inserted row spacing of 20 cm and 25 cm were higher than the row spacing of 30 cm rice before heading, and effective pani-cles per unit area was significantly higher than that of row spacing of 30 cm, but the grain number per spike, seed setting rate, grain weight were decreased than that of row spacing of 30 cm, the yield of row spacing of 30 cm rice was highest. The comprehensive index with row spacing of 30 cm were better than that of row spacing of 20 cm and 25 cm in Nanjing 9108.关键词
