| 摘 要： | 为探讨在一般高产栽培管理条件下,水稻不同群体与产量的关系,为生产上推广合理稀植提供科学依据,新宾满族自治县农业技术推广中心进行了不同插秧行距、不同插秧穴距、不同插秧苗数的复因子试验。通过对冷凉地区水稻不同群体与产量关系的研究,结果表明:插秧苗数、穴数、行距对水稻产量的影响不大;插秧的穴距对水稻产量的影响最大,中下等地力应以13.3～16.5 cm为主,肥沃地块应以20 cm为主。

| Abstract: | A multiple-factor experiment was carried out in Xinbin to study the relationship between population and yield and to provide scientific reference for rational sparse planting of rice.The results showed that the transplanting seedlings,hill numbers,and distances between rows had little effect on yield,but spaces in the row affected yield greatly,which should be between 13.3 or 16.5 cm in the field with low or mediate fertility,and 20 cm in high-fertility field. |
