| 摘 要： | 选用5个超级稻组合,探讨育秧方式、播种量、施肥方式、秧田水分管理4个栽培因子对超级稻秧苗生长的影响.结果表明:采用盘育秧的超级稻秧苗素质显著优于水育秧;一般生产上以25 d秧龄移栽和播量75～150 kg·hm-2为佳;秧田肥料应深施;秧田期深水状态不利于根系生长,无水层能提高分蘖,促进根系生长,增加根冠比,提高秧苗素质. |

| Abstract: | Effects of 4 factors,i.e.,method of rearing seedling,sowing rate,fertilization mode and water management,were studied on the super-rice.The results showed that(a) pan-rearing was superior to water-rearing,(b) transplanting in 25 days after sowing gave the best results,(c) 75-150kg per hm2 was the best sowing rate,and(d) deep-in-soil fertilization was best for the seedling growth.In addition,over supply of water was detrimental to root development,while maintaining no-water-coverage-over-the-ground promoted ... |
