试验结果表明:亩插0.7万~1.3万穴时,随着插植密度的增加,产量随之增加,且亩插1.3万穴时产量最高,亩插1.1万穴次之,与亩插0.9万穴(对照)产量差异显著;当亩插植超过1.3万穴时,产量大幅下降。分析得出优质香稻川优6203在陕西省南郑地区中上等肥力田获得高产的最佳插植密度为1.3万穴/667m~2。
The results showed that with the increase of planting density, the yield increased with the planting density increasing from 7,000 to 13,000 mu. The yield was the highest when mu was inserted at 13,000, followed by 11,000 mu, followed by 9,000 mu Significant differences were observed in the production of holes (control); when the planting of more than 13,000 acre acres, the yield dropped drastically. The results showed that the optimum planting density of high quality Aromatic rice Chuanyou 6203 was 13000 / 667m ~ 2 in middle - upper fertility field of Nanzheng in Shaanxi Province.
