摘要: 研究种植方式和机插密度对优良食味粳稻南粳9108和南粳5718稻米品质的影响。结果表明,与常规种植模式相比,稻虾共作模式提高了稻米整精米率、蛋白质含量和胶稠度,降低了垩白粒率、垩白度和直链淀粉含量,对淀粉RVA谱特征值有较大影响,提高了崩解值,降低了消减值,改善了米饭的外观、硬度、黏度、平衡度和食味品质;机插密度极显著影响稻米垩白粒率和直链淀粉含量(P<0.01),显著影响垩白度和蛋白质含量(P<0.05),米饭的食味品质均随机插密度降低而明显改善。互作分析表明,品种、机插密度和种植模式及其之间的互作对稻米品质产生较为明显作用。

Abstract: The effects of different mechanical-transplanting patterns and densities on the rice quality of Nanjing 9108 and Nanjing 5718, two japonica rice varieties with good taste quality, were studied. The results showed that compared with the conventional cultivation mode, the rice-shrimp co-cropping mode increased the head milled rice rate, protein content and gel consistency of rice, and decreased the chalky grain rate, chalkiness degree and amylose content. The rice-shrimp co-cropping had a greater impact on the starch RVA profile characteristic values. It increased the disintegration value, and reduced the attenuation value. The rice-shrimp co-cropping improved the appearance, hardness, viscosity, equilibrium degree and taste value of the rice. The mechanical-transplanting density had a great influence on chalky grain rate and amylose content(P<0.01), significantly affected chalkiness degree and protein content (P<0.05),and the taste quality of rice was significantly improved with the decrease of the mechanical-transplanting density. The interaction analysis showed that varieties, mechanical-transplanting densities, patterns, and their interactions had significant effects on rice quality.
