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。
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 cultiva-tion mode,the rice-shrimp co-cropping mode increased the head milled rice rate,protein content and gel consistency of rice,and de-creased 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-crop-ping improved the appearance,hardness,viscosity,equilibrium degree and taste value of the rice.The mechanical-transplanting den-sity had a great influence on chalky grain rate and amylose content(P<0.01),significantly affected chalkiness degree and protein con-tent(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.
