湖南稻鸭生态种养水稻品种优选研究

Studies on the Selection of Rice Varieties for Ecological Planting and Breeding of Rice-Ducking in Hunan Province

稻田养鸭作为一种传统农业生产模式,在湖南发展迅速。为筛选出适宜湖南稻鸭生态种养的水稻品种,2021年向全省征集17个优质水稻品种在长沙县进行试种展示。结果表明,悦两优美香新占的稻谷产量和稻米产量分别为8.69 t/hm^(2)和5.90 t/hm^(2),垩白粒率和垩白度分别为2.75%和0.8%,谷草比和收获指数分别为1.08和0.52,株高适中,且遭遇大风天气无倒伏情况发生,可作为湖南稻鸭模式主推水稻品种;湘岳占、悦两优钰占和吨两优900这3个品种可作为稻鸭模式的适宜水稻品种。

As a traditional agricultural production mode,rice-duck integrated farming has developed rapidly in Hunan.In order to screen rice varieties suitable for ecological cultivation of rice-ducking in Hunan,17 high-quality rice varieties collected be tested and displayed in Changsha County in 2021.The results showed that the rice yield,milled rice yield,chalky grain rate,chalkiness,grain grass ratio and harvest index of Yueliangyou Meixiangxingzhan were 8.69 t/hm^(2),5.90 t/hm^(2),2.75%,0.8%,1.08 and 0.52 respectively.And its plant height was moderate,and there was no lodging situation when encountering strong winds.Yueliangyou Meixiangxingzhan can be the main promoted rice variety for the rice-duck integrated farming mode in Hunan Province.The three varieties of Xiangyuezhan,Yueliangyou Yuzhan,Dunliangyou 900 can be used as suitable rice varieties for rice-duck integrated farming mode.
