| 摘 要： | 采用田间小区试验,在水稻移栽时设置6个剪根处理,研究剪根对水稻生育时期、株高、叶面积指数、分蘖数及产量的影响.结果表明,移栽时剪根对株高无明显影响;移栽时留根长度在0～0.5cm会推迟水稻的生育时期,降低分蘖数和叶面积指数,导致产量降低;移栽时留根长1～2cm,虽然分蘖数降低,但有效分蘖数和产量构成因素与对照无明显差异...

| Abstract: | Based on field micro-plot experiments,the effect of root cutting on growth stages,plant height,LAI,tiller numbers and yield of rice were discussed by setting 6 cutting root levels at transplanting stage.The results showed that there was no effect on plant height by cutting root.When root length was lower than 0.5cm at transplanting stage,it could delay the growth stages,reduce tiller numbers and LAI,resulting in the decrease of the production of rice.Although the tiller number was reduced when rice root len... |
