Abstract:

Selecting Suxianggeng 100 as the experimental variety and using the conventional rice-wheat model as a control, this study explored the effects of the rice-morel rotation model on rice yield and quality under different rotation durations. The results showed that compared to the rice-wheat model, neither the three-year nor the one-year rice-morel rotation significantly affected rice yield. However, the rice-morel rotation significantly improved rice milling quality (brown rice rate, milled rice rate, head rice rate) and eating quality (gel consistency, taste value), while significantly reducing cooking characteristics (water absorption of cooked rice, volume expansion rate, dry matter content of rice soup, iodine blue value). In summary, compared to the rice-wheat model, the rice-morel rotation model can improve rice quality without affecting rice yield, resulting in higher overall benefits.

摘要：

选取苏香粳100为供试水稻品种，以常规稻-麦模式为对照，探讨不同轮作年限下水稻-羊肚菌模式对水稻产量与品质的影响。结果显示，与稻-麦模式相比，轮作3年和轮作1年的水稻-羊肚菌模式在水稻产量上均未表现出显著差异，但稻米加工品质（糙米率、精米率、整精米率）和食味品质（胶稠度、食味值）显著提高，蒸煮特性（米饭吸水率、体积膨胀率、米汤干物质、碘蓝值）显著降低。结果表明，与稻-麦模式相比，水稻-羊肚菌模式在不影响水稻产量的前提下，可改善稻米品质，提高综合效益。
