| 摘 要： | 为探索适宜贵定县的水稻栽插密度，以准两优1102为试验材料，开展了6个不同密度的试验研究。结果表明：生育期与栽插密度无关，有效穗数以3300穴／667m2最多，单产变化依次为13300穴／667m2＞12000穴／667m2＞11000穴／667m2＞14000穴／667m2＞15000穴／667m2＞10000穴／667m2，13300穴／667m2与12000穴／667m2无明显差异，适宜栽培密度为12000～13300穴／667m2。

Study on Appropriate Planting Density of Zhunliangyou 1102 |
| |
| Abstract: | To explore appropriate planting density of rice in Guiding,taking Zhunliangyou 1102 as test material,6 densities were stud-ied. The results showed that there is not related on growth stages and planting density,available spikes at 3300 hills/667m2 is greatest, the yield of rice were:13300 hills/667m2 >12000 hills/667m2 >11000 hills/667m2 >14000 hills/667m2 >15000 hills/667m2 >10000 hills/667m2 ,but there is not obviously different between planting density of 13300 hills/667m2 and 12000 hills/667m2 ,so 12000 -13300 hills/667m2 is appropriate to plant in Guiding. |
