为探明钵苗机插方式在稻麦两熟地区对水稻米质性状的影响及其品种类型间差异,本文以常规粳稻、杂交籼稻和籼粳交水稻为材料,比较了钵苗机插、毯苗机插和机械直播3种种植方式在稻麦两熟制高产栽培条件下的稻米加工品质、外观品质、营养品质、蒸煮食味品质特性变化及其品种类型间差异。结果表明,钵苗机插的整精米率比毯苗机插和机械直播分别提高1.6%和4.9%(P<0.05),整精米产量分别提高7.8%和25.9%(P<0.05),改善了稻米加工品质;与毯苗机插和机械直播相比,钵苗机插的稻米垩白米率、垩白面积和垩白度显著增加,对稻米外观品质有不利影响,但钵苗机插精米蛋白质含量较高,有利于稻米营养品质的改良,其精米蛋白质产量分别比毯苗机插和机械直播提高8.7%和28.0%;3种种植方式相比,钵苗机插稻米蒸煮食味品质表现出一定程度的变优趋势,其中,稻米直链淀粉含量、消减值和糊化温度呈钵苗机插<毯苗机插<机械直播的趋势,胶稠度、峰值黏度、热浆黏度、最终黏度和崩解值呈钵苗机插>毯苗机插>机械直播的趋势;食味值于种植方式间无显著差异,呈籼粳交水稻和常规粳稻钵苗机插<毯苗机插<机械直播,杂交籼稻毯苗机插>钵苗机插>机械直播的趋势。由此得出,钵苗机插不仅能增加稻谷产量,还能改善部分稻米品质特征,是稻麦两熟地区实现高产高效优质协调水稻生产的潜力型机械化种植方式。 In order to find out the effect of the seedlings inserted in rice-wheat double-ripening area on the rice quality traits and the differences among the different rice varieties, the rice varieties with conventional rice, hybrid indica rice and indica-japonica rice as materials, Variety of processing quality, appearance quality, nutritional quality, cooking and eating quality characteristics and varieties of three kinds of rice planting under the conditions of double cropping and high yield of rice and wheat were studied. The results showed that the milled rice rate of rice seedlings increased by 1.6% and 4.9% respectively (P <0.05), and the yield of milled rice increased by 7.8% and 25.9% (P <0.05) Rice processing quality; compared with the blanket machine insertion and mechanical live broadcast, the seedling machine inserted rice chalkiness rate, chalky area and chalkiness increased significantly, which had an adverse effect on the appearance quality of the rice, but the bowl seedling machine inserted the rice protein Higher content of rice is conducive to the improvement of nutritional quality, the yield of polished rice, respectively, than the blanket machine plug and mechanical live increased by 8.7% and 28.0%; 3 kinds of planting methods, Degree of change trend, among them, rice amylose content, abatement value and gelatinization temperature were bowl seedling machine inserted blanket machine inserted> the trend of mechanical live; food taste value was no significant difference between planting methods, was indica japonica rice and conventional japonica rice bowl seedling machine inserted < Indica hybrid rice seedlings machine> bowl seedlings Machine inserted> the trend of mechanical live. It is concluded that the seedling machine can not only increase the yield of rice, but also improve the quality characteristics of some rice. It is a potential mechanization planting method to achieve high yield, high quality and coordinated rice production in the region of rice and wheat.
