| 摘 要： | 通过移栽密度对水稻生长发育及产量的影响试验,结果表明:随着移栽密度的变小,前期生长量变小,中后期显著增加,有效分蘖期及分蘖高峰期后延,整个生育期叶色变化平稳,水稻产量增加。最佳移栽密度为30cm×20cm,每穴3苗,产量达到725.2kg/667m2。

| Abstract: | Pass to study the effect that cultivated density on rice growth and yield, the result showed that: as cultivated density diminish, ex-period the growth measure varied small, middle-later period increased obviously, dominate tillering period and height tillering period postponed, and leaf colours varied steady on the whole growth period, rice yield increased. Optimum cultivated density is 30 cm × 20 cm, per cave plant 3, its yield is 725.2 kg/667 m2. |
