摘要:

为探究不同缓(控)释肥在水稻中的使用效率,于浙江省杭州市桐庐县百江镇联盟村开展试验,以‘甬优1538’为供试水稻品种,设置常规施肥、茂施控释肥、司尔特缓释肥和茂施俩控缓释肥4种处理,对各小区水稻产量及土壤化学性质测定,结合土壤酶活性及微生物等指标分析,评价不同缓(控)释肥对水稻化肥减量增效和土壤各类性状的影响。试验结果表明:在肥料养分数量下降13%的情况下,水稻理论产量与实际产量一致,茂施俩控缓释肥处理>司尔特缓释肥处理>常规处理>茂施控释肥处理;水稻施用缓(控)肥,其节本增效和肥料减量增效作用以施用司尔特缓释肥和茂施俩控缓释肥为较好;司尔特缓释肥处理和茂施俩控缓释肥处理的水稻籽粒和秸秆的全氮、全磷和全钾含量相对较多,茂施俩控缓释肥处理后对改善土壤各类化学性状及生物学特性最好。综上所述,施用茂施俩控缓释肥效果最佳。

Abstract:

To explore the efficiency of different slow (controlled) release fertilizers in rice, this experiment set up four treatments of fertilization: conventional fertilization, Maoshi controlled-release fertilizer, Sirte slow-release fertilizer, and Maoshi dual control slow-release fertilizer. The rice yield and soil chemical properties were measured in each plot, and the effects of different slow (controlled) release fertilizers on reduction and efficiency of rice fertilizer, soil fertility and determination of soil chemical properties were evaluated using combination of the analysis of soil enzyme activity and microorganism indicators. The results showed that when fertilizer nutrients quantity decreased by 13%, the theoretical yield of rice was consistent with the actual yield, with Maoshi dual control slow-release fertilizer treatment>Sirte slow-release fertilizer treatment>conventional fertilization treatment>Maoshi controlled-release fertilizer treatment; under the application of slow (controlled) release fertilizer in rice, the cost-saving and fertilizer reduction effect of Sirte slow-release fertilizer and Maoshi dual control slow-release fertilizer were the better; the total nitrogen, total phosphorus, and total potassium content of rice grains and straw treated with Sirte slow-release fertilizer and Maoshi dual control slow-release fertilizer were relatively higher. Maoshi dual control slow-release fertilizer treatment had the best effect on improving various chemical and biological characteristics of soil. Based on the above results, it can be concluded that the application of Maoshi dual control slow-release fertilizer had the best effect.
