利用迟熟中粳武育粳 3号设置不同抛栽深度处理的试验表明 :抛栽深度 1 .0～ 2 .0 cm有利于立苗发棵 ;抛栽深度 0～ 3 cm范围内与产量呈显著的抛物线关系 ,最适点为 1 .5cm,抛栽过深过浅都不利于高产 .秧苗入土越深植株的抗根倒能力越强 .
The experiment of using late maturity Chinese Wuyujing 3 to set different throwing depths showed that the throwing depth of 1.0-2.0 cm was beneficial to stand seedlings and the seedling height of 0-3 cm and the yield of Significant parabolic relationship, the most suitable point is 1 .5 cm, cast too far too shallow is not conducive to high yield. Seedling deeper plants resistant to root fall ability.
