摘要
利用随机区组试验设计,研究了种植密度对F优498产量的影响。结果表明:密度是影响产量的重要因素,F优498以密度为12444窝/667m2产量最高,纯收益第2,以密度为8167窝/667m2纯收益最高。
In order to explore the appropriate planting density of You 489,a signal factor randomized bloke design of planting density was applied on the effect of yield and economic benefits.The results indicated that density was a vital factor of rice production and12444 plants / 667m2 was the highest yield but its net income was second,however,the highest net income treatment was 8167 plants /667m2.
