稻虾共作模式下优质水稻品种比较试验研究

Comparative Experiment of High-quality Rice Varieties under Rice-shrimp Co-cropping System

为了筛选出适宜广西稻虾共作模式种植的优质、高产、抗逆性强的水稻品种,以8个广西优质水稻品种为供试材料,在桂平市进行水稻品种比较试验。结果表明,在8个参试水稻品种中,万太优3158、野香优9号、昌两优馥香占、万太优美占种植产量与综合性状表现突出,可在桂平市稻虾共作模式下推广种植,也可在生态条件相同的地区推广利用;野香优莉丝、桂育9号、桂育12号、桂野丰种植产量与综合性状表现不理想,不宜在桂平市稻虾共作模式下种植。根据研究结果,提出优质水稻品种的选择条件以及生态栽培技术,为广西稻虾共作模式可持续发展提供依据。

In order to select the high-quality,high-yielding and stress-resistant rice varieties suitable for planting in the rice-shrimp co-cultivation mode in Guangxi,8 high-quality rice varieties in Guangxi were selected as test materials,and the comparative test of rice varieties was conducted in Guiping City.The results showed that among the eight participating rice varieties,Wantaiyou 3158,Yexiangyou No.9,Changliangyou Fuxiangzhan and Wantaiyuyu had outstanding planting yields and comprehensive traits,which could be promoted in the rice-shrimp co-cultivation mode of Guiping City,and could also be promoted and utilized in areas with the same ecological conditions.The planting yield and comprehensive performance of Yexiang Yulisi,Guiyu No.9,Guiyu No.12,and Guiyefeng were not satisfactory,and it was not suitable to be planted in the rice-shrimp co-cultivation mode of Guiping City.According to the research results,the selection conditions of high-quality rice varieties and ecological cultivation technology measures were proposed,which provided a basis for the sustainable development of rice-shrimp co-cultivation mode in Guangxi.
