探讨了旱育秧不同品种、不同栽插方式的适宜密度阈值。研究认为：中籼抛栽稻，每m2抛24-27穴，基本茎蘖苗80～100万，中籼手栽稻，每m2栽27-31穴，基本茎蘖苗100～120苗，中粳稻每m2抛栽或手栽45～50穴，基本茎蘖苗130～150苗，有利个体群体兼顾协调，获得高产。
The appropriate density thresholds for different varieties and transplanting methods were discussed. The study shows that the medium-throwing rice throws 24-27 points per m2 and the basic stem-tillering seedlings is 80-100 million. The medium-indica hand-planting rice has 27-31 points per m2 and the basic stem-tillering seedlings is 100-120 seedlings. 45 or 50 holes of japonica rice are planted or planted in hand and 130-150 seedlings of basic stem and tillering seedlings are beneficial for both individual groups to achieve high yield.
