| 摘 要： | 两年试验结果表明:钵体育苗每孔播3粒时比6粒和9粒分别增产3.1%和10%;每穴插秧苗数2～4株时产量最高,比1株和5株高11.1%和9.7%;插秧密小于30 cm×20 cm或大于30 cm×26.7 cm时,减产幅度都显著。所以水稻开发多年的盐碱地水稻田应该改变密植、主穗增产的栽培方法,采取稀植、促进分蘖、大穗增产的栽培技术。 |

| Abstract: | Two years experiments showed that(1) the 3 seeds per bowl treatment increased yield 3.1% and 10% than 6 and 9 seeds per bowl respectively in bowl seedling;(2) transplanted 2 to 4 seedlings per hill leaded to highest yield comparing to 1 and 5 seedlings per hill(increasing yield 11.1% and 9.7%,respectively);(3) it would significantly reduce the yield when the planting density is lower than 30㎝×20㎝ or higher than 30㎝×26.7㎝.This result suggested that the old cultivation method which increased planting density and depended on the contribution of main panicle to yield should be changed.In saline-alkali soil paddy which planting rice for many years,some cultivation technologies would increase the yield which to reduce the seeding rate,transplanting seedling per hill and planting density. |
