早熟杂交水稻黔优107不同栽插方式和密度试验

Effects of Different Planting Pattern and Seedling Density on Yield of Qianyou 107,a Hybrid Rice Variety with Early Mature

为探索早熟杂交稻黔优107的高产栽培技术,2007年在安顺高海拔区(1 410 m)中等肥力田,进行了一组不同栽插方式和密度试验。结果表明,宽窄行栽插处理平均产量632.6 kg/667m2,比宽行窄株栽插处理平均产量增产5.5%;最佳处理产量达646 kg/667m2,其栽插规格为(33.3+16.65)cm×15.23 cm,密度为1.75万穴/667 m2。

The two-factor split plot design was used in the middle fertility field to study the effects of different planting pattern and seedling density on yield of Qianyou 107 for probing the cultivation technique for higher yield of Qianyou 107, a hybrid rice variety with early mature. The results show that the average yield of planting seedlings with wide-narrow row pattern is 632. 6 kg/667m^2 , 5.5 % higher than that of planting seedlings with wide row and narrow plant spacing pattern, and the maximum yield （646 kg/667m^2） can be obtained under （33.3＋16.65）cm× 15.23 cm of planting pattern and 17.5 thousand seedlings of planting density.
