9个不同水稻品种的比较试验

Comparative Experiment of Nine Different Rice Varieties

[目的]筛选适宜在兴化市种植的高产优质抗逆性好的水稻品种。[方法]通过田间对比试验,对9个示范水稻品种的生育期、农艺性状、经济性状、抗逆性及丰产性进行比较分析。[结果]润禾1号生育期最短,为129 d,其他品种生育期为136~138 d;兴作1号、盐绠6号、08-49、南粳40和润禾1号产量超过7 552.50 kg/hm2;兴作1号和盐绠6号抗倒性好,成穗率偏低,08-49和润禾1号零星发生恶苗病,润禾1号零星发生基腐病。[结论]兴作1号、盐绠6号和08-49产量表现好、抗性强,可以作为兴化市示范推广品种。

[Objective] The aim was to select the suitable and fine rice varieties with the characteristics of high yield,good quality and disease resistance in Xinghua city.[Method] Baesd on field comparison test,the growth period,agronomic traits,economic character,stress resistance and high yield of 9 rice varieties were comparative analysis.[Result] The growth period of Runhe No.1 was the shortest,129 d,and the growth period of the other varieties was 136～138 d.The yields of Xingzuo No.1,Yangeng No.6,08-49 and Runhe No.1 were above 7 552.50 kg/hm2.The lodging resistance of Xingzuo No.1 and Yangeng No.6 was higher and the spike rate was low.The bakanae disease of 08-49 and Runhe No.1 occurred sporadically.The foot rot was found in Runhe No.1.[Conclusion] Xingzuo No.1,Yangeng No.6 and 08-49 with the characteristics of high yield and disease resistance were suitable for spread and demonstrate in Xinghua city.
