摘要
研究了二晚盘育抛栽秧苗的化控技术，结果表明：采用１００μｇ／ｋｇ５％烯效唑浸种和一叶一心期用１５％多效唑喷施能有效地控制秧苗徒长，培育出适宜抛栽的矮壮秧苗，且比常规育秧手插稻增产２５．９％。
The chemical control techniques of double cropping late rice seedlings which were cultivated on soft tray and transplanted by broadcasting were studied, the results showed that soaking seed with 5% S3307 at the concentration of 100g/kg and spraying 15% PP333 at the concentration of 100mg/kg at one leaf and one heart leaf stage could effectively control the excessive growth of seedlings, could cultivate short , healthy and strong seedlings suitable for transplanting by broadcasting, and could increase yield by 25.9% in comparison with the conventional rice seedlings which were cultivated on seedling bed and transplanted by hand.\;
