| 摘 要： | 对水稻产量１１７１５．９ｋｇ／ｈｍ＾２的构成及其生长发育规律进行了研究。结果表明，高产田每平方米有效穗数在４５０个左右，有效分蘖率在８６％以上，每平方米实粒数达４．２万粒，齐穗期叶面积指数（ＬＡＩ）为６．８，齐穗期中层叶片的消光系数为０．６１，下层叶片的光照强度在光补偿点以上。

| Abstract: | The yield and construct development of rice yield 11 715.9 kg/hm 2 were studied.The results showed that the effective ear of grain per square meter are about 450; effective tillering rate are above 86%,bear fruit grains are 4.2 ten thousand per square meter; LAI is 6.8 at heading stage; Optical coefficient in the middle level leaf is 0.61 at heading stage; the illumination intensity in the lower level leaf is over the light compensate point. |
