    摘要:

    目的:为了探讨不同施肥模式对水稻产量及土壤肥力的影响,找到不同肥力水平土壤的最佳施肥模式。方法:本试验在浏阳市荷花镇(低产田)、达浒镇(高产田),比较不施肥(T1)、常规施肥(T2)、40%有机肥(T3)和纯化肥(T4)的水稻产量和土壤肥力变化。结果:施肥处理均能显著提高荷花、达浒两地水稻产量。T2和T3处理能通过增加水稻有效穗数和每穗粒数使水稻产量显著增加。在荷花,T4处理比T1~T3处理分别增产49.8%、2.28%、0.08%;在达浒,T3处理比T1、T2、T4处理分别增产34.15%、12.43%、8.84%。两地土壤养分含量、肥力综合评价值均表现出T3处理显著高于其他处理,且逐年增加。结论:不施肥会降低水稻产量和土壤肥力。低产田在短年限内农家习惯施肥能显著提高水稻产量和土壤养分,但长远培肥应该适当加大有机肥的比例;高产田有机无机肥配施能够达到很好的培肥效果。

    Abstract:

    Objective of this study was to explore the effects of different fertilization patterns on rice yield and soil fertility, and found the best fertilization patterns on paddy field with different fertility levels. In this study, rice yield and soil fertility changes of non-fertilization(T1), conventional fertilization(T2), 40% organic fertilizer(T3) and pure fertilizer(T4) were compared in Hehua village(low-yielding field) and Dahu village(high-yielding field). Results showed that fertilization treatment significantly improved the yield of rice in Hehua and Dahu. Rice yield of T2 and T3 treatments was significantly increased by increasing the number of effective ears and grains per ear. In Hehua, production of T4 treatment increased by 49.8%, 2.28% and 0.08%, respectively, compared with T1-T3. In Dahu, production of T3 treatment increased by 34.15%, 12.43% and 8.84%, respectively, compared with T1, T2 and T4. The comprehensive evaluation value of soil nutrient content and fertility in both places showed that T3 treatment was significantly higher than that of other treatments, and it increased year by year. In conclusion, not applying fertilizer can reduce rice yield and soil fertility. Conventional fertilization in low-yielding fields can significantly improve rice yield and soil nutrients in a short period of time, but the proportion of organic fertilizer should be appropriately increased in long-term fertilization. The application of organic and inorganic fertilizer in high yield field can achieve good effect of fertilizer cultivation.
