通过播栽密度和施氮方式两试验结果的分析表明 :产量构成 4因素中 ,每穗颖花数是左右库限制型中粳品种西光产量的首要因子。稀播少本栽比密播多本栽平均每穗颖花数增加 3 9.7% ,增产 18.4%。增施攻花肥比不施攻花肥 (一轰头 )平均每穗颖花数增加 19.2 %～ 11.1% ,增产 11.2 %～ 3 .1%。稀播少本栽和增施攻花肥配套是库限制型品种西光扩库增产的有效途径
The results of two test results of sowing density and nitrogen application showed that among the four factors of yield formation, the number of spikelet per spike was the most important factor in the light yield of the limited japonica rice varieties. Sowing less broadcast than the inveterate transplanting more than the average number of spikelets per panicle increased by 3 9.7%, an increase of 18.4%. Increasing the rate of attacking and fertilizing than not attacking Huafu (a headache) increased the average number of spikelets per panicle by 19.2% ~ 11.1% and increased by 11.2% ~ 3.1%. Sowing less planting planted by attacking and fertilizing is an effective way to increase the yield of Xikuangkuang
