摘要
为明确三系杂交籼稻新组合广8优8318在浙江省台州市的产量、品质和生育特性表现,以当地主栽品种中浙优8号为对照(CK),于2018-2021年在该市不同地区进行试验示范。结果表明,广8优8318产量为8.13~9.86 t/hm^(2),稻米品质为部标3级,全生育期124~147 d;与CK相比,该组合表现出产量高、品质等级相同、生育期适宜、分蘖力强、干物质积累量大、收获指数和温光资源利用率高等特点。综上,广8优8318适宜在台州市大面积推广应用。
To clarify the grain yield,quality and growth characteristics of the new three-line indica hybrid rice combination Guang 8 You 8318 planted in Taizhou City,Zhejiang Province,the experiments were conducted at different locations of the city from 2018 to 2021,taking the local dominant hybrid rice variety Zhongzheyou 8 as the control(CK).The results showed that the yield of Guang 8 You 8318 was 8.13~9.86 t/hm^(2),the grain quality reached the ministry standard 3 and the whole growth period was 124~147 d.Compared with CK,Guang 8 You 8318 showed the characteristics of higher yield,same quality grade,suitable growth period,stronger tillering ability,larger dry matter accumulation,higher harvest index and higher utilization rate of temperature and light resources.In summary,Guang 8 You 8318 is suitable for large-scale promotion and application in Taizhou.
