| 摘 要： | 以每丛插植不同谷粒数苗、不同插植密度、不同施氮量和同氮量下不同时期追肥比例等来研究光优6063的有关高产栽培措施,结果表明:丛插1粒谷苗与2粒谷苗间产量差异不显著,插植密度为20cm×16.7cm 的单位面积产量最高。光优6063是个较耐肥的组合。每公顷施氮量180kg 的产量最高。且在较高氮肥水平下每公斤氮的稻谷转化率高于低氮水平下的。

| Abstract: | In this paper,some cultivation practices for the two-line hybrid rice Guangyou 6063 were stu- died in those aspects as seedling-transplanting numbers per clump,different transplanting densities,different amount of N fertilization and different ratios of N fertilization at three growth stages.Results showed that yields were not significantly different between the treatments of one-seedling planting per clump and two-seedling planting per clump,and the highest yield could be achieved by planting standard treatment of 20 cm×16.7 cm.Results also showed that Guangyou 6063 was a fertilizer-favour crossing combination with the highest yield from 180kg N per hectare and grain exchange ratios of N fertilizer per kg were higher in high N level treatments than those in low N level treatments. |
