以连作晚稻新品种甬优2640为材料,通过品比试验和播种期试验,研究其在金华地区的生态适应性及不同栽培方式下适宜的播种期。试验表明:甬优2640耐迟播,全生育期适中,穗大粒多,丰产性好,适合在金华地区作为连作晚稻种植;甬优2640机插和手插皆宜,机插甬优2640在7月5日前播种,手插稻在7月10日之前播种均能正常抽穗和灌浆,产量有保障。研究结果表明,甬优2640在金华作为连作晚稻栽培安全可行,规模种植大户可将其作为主栽品种种植。
The new hybrid rice, Yongyou 2640, was used as the material to study the ecological adaptability of Jinyue region and the suitable sowing date under different cultivation methods through the ratio test and sowing date. The results showed that: Yongyou 2640 was tolerant to delayed sowing, had moderate growth period, large spike and large grain yield, suitable for planting late rice in continuous cropping in Jinhua. Yongyou 2640 was suitable for planting and hand insertion, Sowed on the 5th of the month, the hand-inserted rice can be heading and grouting normally before sowing on July 10, and the yield is guaranteed. The results showed that Yongyou 2640 was safe and feasible for continuous cropping of late rice in Jinhua, and large-scale planting could be planted as main cultivars.
