摘要: 在黄河三角洲地区设计稻鸭共生、人工除草、常规稻作3种栽培模式,研究其对稻米加工品质、外观品质、蒸煮和食味品质、卫生品质的影响.结果表明:与常规稻作相比,稻鸭共生可以增加水稻粒宽,提高糙米率、精米率、整精米率,减少垩白,这主要是由于有效穗数和籽粒重的提高以及弱势粒的降低所致.稻鸭共生和人工除草栽培模式可以增加胶稠度,降低直连淀粉和蛋白质含量,改善稻米食味性,这主要归功于有机肥的施用.由于生产过程不施用化学肥料和农药,稻鸭共生、人工除草模式可以大幅降低甚至检测不到农药残留.稻鸭共生既可改善稻米品质,又能保护环境,为优质水稻生产提供了一条较好的生态技术途径.

Abstract: Three cultivation models including rice-duck mutualistic, manual weeding and conventional rice farming were designed in the Yellow River Delta area to study the effects on rice milling quality, appearance quality, cooking and eating quality, and sanitation quality. The results showed that compared to conventional rice farming, the rice-duckmutualistic treatment increased grain width and brown rice rate, milled rice rate, head rice rate and reduced the chalkiness. This was mainly due to the increase of panicle numbers and grain mass and the decrease of the inferior grains. Due to the application of organic manure, the gel consistency increased, amylose and protein contents decreased, and the rice taste improved under rice-duck mutualistic and manual weeding cultivation treatments. As no chemical fertilizers and pesticides were applied under rice-duck mutualistic and manual weeding treatments, pesticide residues were greatly reduced or even not detected. Rice duck farming could improve the quality of rice and protect the environment, which would be a good ecological technology for high quality rice production.
