Abstract:

The effects of different fertilizer types and fertilization methods on grain quality of rice were compared and studied, and the appropriate amount of rice straw wet compost was also discussed in this paper. The results showed that rice chalkiness, protein content and other indicators were significantly different between different fertilization treatments, the treatments with rice straw wet compost had higher taste value, among them, the taste value of the treatment with 50% rice straw compost + 25% fertilizer was the highest. Rice straw wet compost had great effects on improving rice chalky, taste and reducing the amount of fertilizer, it could be used as one of the important measures for high quality rice production.

Key words: high quality rice, rice straw wet compost, rice chalkiness, protein content, taste value

摘要：

比较研究了不同肥料种类及运筹方式对稻米品质的影响，并探讨了水稻秸秆堆沤肥的适宜施用量。结果表明，不同施肥处理之间稻米垩白、蛋白质含量等指标存在较大差异，施用秸秆堆沤肥的处理稻米食味值均较高，其中，50%水稻秸秆堆沤肥+25%化肥的处理食味值最高。可见，水稻秸秆堆沤肥具有改善稻米垩白、提高食味品质及减少化肥用量等作用，可作为优质水稻生产的重要措施。
