Abstract:

Using Nanjing 9108 as a test material, the effects of different rice cultivation patterns on the yield, quality and benefit of high-quality rice variety were studied. The results showed that the actual yields from high to low were pot seedling machine transplanting, blanket seedling machine transplanting, rice-duck farming system, and rice- crayfish farming system. The whole milled rice rate were rice-duck farming system > rice-crayfish farming system > seedling machine transplanting > blanket seedling machine transplanting. The chalky rice rate and chalkiness of seedling machine transplanting was the highest, and rice-duck farming system was the lowest. The appearance quality of rice in rice comprehensive planting mode was better. The rice comprehensive planting mode not only reduced the protein content and amylose content, but also increased the gel consistency, and its RVA profile showed a decrease in the setback and the a increase in breakdown value, which improved the cooking and eating quality of Nangeng 9108. The economic benefits from high to low were rice-crayfish farming system, rice-duck farming system, pot seedling machine transplanting and blanket seedling machine transplanting. The economic benefit of comprehensive planting and breeding mode were significantly higher than that of traditional single rice mode.
