浙西南山区单季晚稻‘甬优15号’机插高产群体培育及配套栽培技术

High-yield Cultivation Techniques for Mechanical Transplanting of the Single Cropping ‘Yongyou No.15' Rice for Mountain Area in the Southwest of Zhejiang Province

为进一步减轻种粮劳动强度,降低生产成本,提高种粮效益,在浙西南山区开展了单季晚稻‘甬优15号’机械育秧、机械插秧高产栽培技术研究。结果表明:通过培育壮秧、宽行密株、小苗移栽、加强肥水管理和病虫防治等技术措施,‘甬优15号’机插产量11.0 t/hm2以上的穗粒结构为有效穗200万/hm2、每穗总粒240粒、每穗实粒210粒、千粒重27.5g左右。

In order to further reduce the labor intensity of grain, reduce production costs and improve efficiency of grain, the authors studied on the yield cultivation techniques of the single cropping late rice ＇Yongyou No.15＇ in rice breeding and transplanting with machine. The results showed ＇Yongyou No.15＇ mechanical transplanting more grain yield 11.0 t/hm2 structure panicle 2000000/hm2, total grains perpanicle 240, 210 grains per panicle, grain weight of about 27.5 g by cultivating strong seedling, wide row dense lines, transplanting seedlings, fertilizer management and strengthening pest control and other technical measures.
