摘　　要：以‘津原89’‘津育粳22’和‘津原香98’为供试材料,设置稻田养蟹和非养蟹2个处理,对两种种植模式下水稻产量、品质和经济效益进行了比较。结果表明:不同品种水稻在两种种植模式下的产量性状、外观、主成分以及食味品尝评价方面的表现存在差异。稻田养蟹处理显著提高了3个水稻品种的整精米率,显著降低了‘津原89’的垩白粒率;‘津育粳22’的蛋白质和直链淀粉含量显著低于非养蟹处理;稻田养蟹和非养蟹处理下3个品种的稻米食味值和食味综合评价无显著差异。‘津原89’和‘津育粳22’的产量略高于非养蟹处理,而‘津原香98’产量略低于非养蟹处理。从经济效益分析来看,3个品种稻蟹种养模式明显高于常规种植模式。Taking‘Jinyuan 89’‘jinyujing 22’and‘Jinyuanxiang 98’as materials,with two sets of crab raising and non-crab raising paddy fields,the yield,quality and economic benefits of the two planting modes were compared.The results showed that different varieties had different performances in yield characters,appearance,principal components and taste evaluation under the two planting modes.Head rice rate of the three rice varieties significantly increased through the crab-rearing treatment,and significantly reduced the chalky grain rate of‘Jinyuan 89’.The contents of protein and amylose in‘Jinyujing 22’were significantly lower than those in non-crab culture.There were no significant differences in rice taste value and comprehensive evaluation of rice taste among the three rice varieties under crab and non-crab treatments.The yield of‘Jinyuan 89’and‘Jinyujing 22’was slightly higher than that of non-crab-raising treatment,while the yield of‘Jinyuan Xiang98’was slightly lower than that of non-crab-raising treatment.From the analysis of economic benefit,the crab raising mode of three varieties was significantly higher than that of non-crab raising.
