上虞区常规连作晚粳稻品种对比

Comparison experiment of conventional continuous cropping late japonica rice varieties in Shangyu District

绍兴市上虞区是浙江省粮食主产区,种植的主要模式为双季稻,常年种植双季晚稻面积大,但目前种植的连作晚稻存在品种单一、主栽品种种植年限长等不足,迫切需要引入熟期适中、优质高产、抗性较强的新品种作为主栽品种,为连作晚稻的稳产高产奠定基础。为此,2022年该地区引入秀水7204和春江166等4个新品种,进行大区对比。结果表明,参试新品种熟期、产量、抗性等均优于当年的主栽品种,适宜在上虞区作为双季晚稻推广种植。

Shangyu District of Shaoxing City is the main grain producing area of Zhejiang Province,the main mode of planting is double cropping rice,and the perennial planting of double cropping late rice has a large area,but the current continuous cropping late rice has a single variety,the main variety has a long planting life,etc.,and it is urgent to introduce new varieties with moderate maturity,high quality and high yield,and strong resistance as the main varieties,so as to lay the foundation for the stable and high yield of continuous cropping late rice.To this end,in 2022,4 new varieties were introduced,including Xiushui 7204 and Chunjiang 166,for regional comparison.The results showed that the maturity date,yield and resistance of the new varieties were better than those of the main cultivars of the year,and they were suitable for planting as double-cropping late rice in Shangyu Area.
