摘要：

（研究目的）开展连作晚稻机插秧技术的探讨对于解决传统手工插种费工费时成本高问题，促进双季稻发展有积极意义。（方法）通过适合连作晚稻机插水稻品种、机插密度和用氮量等方面试验与筛选；（结果）试验结果表明，甬优6号作连作晚稻机插生育期适中，以大穗获得较高产。产量随插秧密度提高而增加的趋势明显，提高氮肥用量能较好地提高有效穗数，但每穗总粒和实粒数相应减少。机插密度以1.39万丛/667m2（30 cm×16 cm）为宜，氮肥用量以每667m2纯氮11kg左右为好；（结论）甬优6号作连作晚稻机插，较高的机插密度能在较低用氮量的情况下获得较高产量。

Abstract:

（OBJECTIVE）It is positive significance to research machanical transplanting technology for late rice to solve the problem of higher cost and more labor the traditional transplanting by hand; （METHOD）We selected suitable late rice varieties by machine transplanting and carried out the experiments of the rate of nitrogen; （RESULTS）The results showed that Yongyou 6 had a suitable growing period and large panicle by machine transplanting. The grain yield was increased with more transplanting density by machine. The productive panicles were increased with more nitrogen fertilizer , but the total grains per panicle and filled grains was decreased. It is the most suitable planting method that was transplanting density of 13900 hills / 667m2 (30 cm × 16 cm) and nitrogen fertilizer rate of about 11kg per 667m2; （CONCLUSION）Yongyou 6 got higher yield in late season with machine transplanting under higher density and less nitrogen rate.
