杂交中稻品种在稻鱼环境中的生态适应性研究

    Study on the Ecological Adaptability of Hybrid Mid-season Rice Varieties in the Environment of Rice-fish Symbiosis

    • 摘要: 为筛选出适于稻鱼环境的水稻优良品种,以野香优676、Y两优5866、晶两优华占、Y两优676、万象优111、臻优727、中浙优8号、农两优3135、深两优332等9个杂交中籼稻品种为供试材料,在稻田养鱼环境条件下,采用单因素随机区组设计,对参试品种的产量、抗性等表现进行了考察。结果表明:Y两优5866、中浙优8号、臻优727这3个品种生育期适中,综合抗性好,产量高,米质较优;深两优332和晶两优华占2个品种在稻鱼环境下的综合表现较好;野香优676生育期适中,产量高,米质佳,但稻曲病发生严重;农两优3135、万象优111和Y两优676这3个品种产量、品质、抗病性均表现一般。从各参试品种的综合表现来看,Y两优5866、中浙优8号、臻优727比较适宜稻鱼环境,可重点推广。

       

      Abstract: In order to select the good varieties of rice suitable for the environment of rice-fish symbiosis, 9 varieties of hybrid medium indica rice were selected as the test materials, including Yexiangyou 676, Yliangyou 5866, Jingliangyouhuazhan, Yliangyou 676, Wanxiangyou 111, Zhenyou 727, Zhongzheyou No.8, Nongliangyou 3135 and Shenliangyou 332. The yield and resistance of the tested varieties were investigated by using the single factor randomized block design under the environmental conditions of raising fish in paddy field. The results showed that the three varieties including Yliangyou 5866, Zhongzheyou No.8 and Zhenyou 727 had moderate growth period, good comprehensive resistance, high yield and good grain quality. Shenliangyou 332 and Jingliangyouhuazhan had better comprehensive performance in the environment of rice-fish symbiosis. Yexiangyou 676 had a moderate growth period, with high yield and good grain quality, but the rice false smut occurred seriously. However, the yield, quality and disease resistance of Nongliangyou 3135, Wanxiangyou 111 and Yliangyou 676 were general. According to the comprehensive performance of the tested varieties, Yliangyou 5866, Zhongzheyou No.8 and Zhenyou 727 were more suitable for the environment of rice-fish symbiosis, which could be promoted vigorously.
