| 摘 要： | 研究了四个不同因素对杂交早稻免耕抛栽立苗的影响。结果表明：适宜的浅水（1cm左右）抛栽、短秧龄（20d）抛栽和前期适当增施氮肥，有利于扎根立苗，早生快发，促进地上部生长。非直立苗的立苗速度与秧龄长短有很大关系，短秧龄有利于加快非直立苗的立苗速度和水稻生长。

| Abstract: | The effects of four factors on techniques for seedling establishment of No-tillage seedling broadcasting cultivation of early hybrid rice were studied.The results showed that no-tillage seedling broadcasting cultivation was beneficial to root standing,seedling establishment,early growth and above-soil growth under the condition of appropriate low water(around 1 cm), short seedling age and appropriate in crease N at the early growth stage.The speed of seedling establishment no-direct seedlings had great relation to seedling age,short seedling age quickened seedling establishment and promoted rice growth. |
