摘要
用 3个不同熟期的杂交水稻组合,采用强化栽培 (SRI)与“三角丛植”方式和超高产施肥的集成技术,在贵阳 (海拔1 140m)的试验结果与常规栽培(CK)的结果比较,有效穗和颖花数增加达极显著。早熟组合黔两优 58产量达 11 437. 5kg/hm2,比CK增产 14. 66%;晚熟组合汕优 63产量为 10 717. 5kg/hm2,比CK增产 10. 52%;中熟组合金优 431产量达 12 837. 0kg/hm2超高产水平。为贵州杂交水稻提高单产初步探索出一条有效的技术途径。
The integrated cultivation technique which included SRI, triangle transplanting and fertilization technique was tested in Guiyang(1140m). The results were compared with results of the same combinations in normal cultivation. Amount of effective spikes and glumes of all combinations increased significantly. The yield of Qian Liangyou 58 was 11437.5kg/ha which increased (14.66%), Shanyou 63 was 11437.5kg/ha which increased 10.52%. The yield of Jinyou 431 was 12837kg/ha. The (integraed) (cultivaion) (technique) is an effective method for yield increasing of hybrid rice in Guizhou.
