摘要
2017年在福清市用甬优2640作早稻不同种植密度比较试验,结果表明:以每667m^2种植密度1.25万~1.5万丛产量最高,说明合理的群体结构能有效协调群体与个体之间关系,化解水稻产量构成各因素之间矛盾,形成合理的穗粒结构,易获高产。
Planting density experiment of early rice Yongyou 2640 was conducted in Fuqing in 2017, results indicated that density of 12 500 - 15 000 plant per 667m2 had the highest yield, which had harmonious structure between population and individuals for balance yield components, developing rational paniclespikelet structure.
