试验以单季晚粳 80 0 6为材料 ,研究栽插行距及配置方式对产量结构及群体质量的影响。结果表明 :适当扩大行距 ,抽穗期群体叶面积适宜 ,抽穗后干物质积累多 ,产量提高 ;宽窄行方式扩行能提高成穗率 ,且比等行方式更能提高每穗颖花数、结实颖花数、结实率 ,协调穗粒重 ,从而提高产量。
The experiment used the single season japonica rice 80 0 6 as material to study the effect of planting spacing and arrangement on yield structure and population quality. The results showed that: the appropriate row spacing, the appropriate leaf area at heading stage, more dry matter accumulation after heading, the yield increased; width and width row expansion can increase the rate of panicle formation, The number of spikes, seed setting rate, coordinating grain weight, thereby increasing the yield.
