摘　　要：采取田间定位试验与室内分析相结合的方法,研究了有机稻蟹(M1～M4)、常规稻蟹(MNP)与单作水稻(CK)生产对水稻产量、河蟹产量、稻米品质的影响。结果表明,与MNP和CK相比,有机稻蟹各处理的水稻穗粒数、实粒数和结实率显著提高,尤其以M1处理增加最为明显,但有效穗数却显著减少;2009年M1处理稻谷产量显著高于CK;有机稻蟹各处理的稻米品质也得到不同程度改善,稻米的糙米率、精米率及整精米率随有机肥施用量的增加有显著提高趋势,稻米的垩白粒率、垩白度及直链淀粉含量显著降低,而稻米的蛋白质、胶稠度、食味值明显提高。2年间河蟹产量的变化趋势相同,均表现为M1>M2>M3>MNP>M4。因此,有机稻蟹生产可在一定程度上提高稻蟹产量和改善稻米品质,为优质稻米的生产以及有机肥的合理利用提供了一条较好的生态技术途径。Field experiments and laboratory analyses were conducted to investigate effect of the three rice production models,organic rice-crab（M1~M4）,conventional rice-crab（NMP） and monoculture rice（CK） on rice-crab yield and rice quality.The results showed that the grain number per panicle,seed-setting rate and 100-grain weight were increased significantly in model of organic rice-crab compared with the other two models,especially the M1 treatment which was significantly increased,but effective spikes of M1 treatment was significantly decreased.The organic rice-crab of M1 treatment was significantly higher than CK treatment in 2009.At the same time the quality of orgainc rice-crab rice was imrpoved with the increase of organic fertilizer inputs,and the chalky rice rate,chalky degree adn amylase content were significantly lower,while rice protein,gel consistency and taste value were significantly improved.In addition,the crab yield in 2009 and 2010 were expressed the same general trend as M1〉M2〉M3〉MNP〉M4.It was concluded that,organic rice-crab production model could increase rice-crab yield and improve rice grain quality in some degree,therefore it is an effective ecological technology for high-quality rice production and rational application of organic fertilizer.
