摘要
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 .
A series of experiments aboutplantdepth was conducted with middle-late variety Wuyu- geng No.3 during1 996～ 1 997.Resultsshowed thatitwasbeneficial to standing and establishing of seedling in plant depth1 .0～ 2 .0 cm.The relation between plant depth(0～ 3 cm) and yield was a parabolic curve,the optimal depth was about 1 .5 cm. But the deeper the plant depth is,the stronger resistance of rootlodging is.
