摘要
[目的]为了研究有机药肥在水稻田的施用效果，分析有机药肥对土壤结构、水稻经济性状和水稻产量的影响。[方法]采用比较法。[结果]在水稻常规施肥的情况下，增施有机药肥750kg／hm^2，可以有效地降低土壤容重，提高水稻经济性状和水稻产量。[结论]增施有机药肥可以改善土壤结构，提高作物产量，减少化肥用量的10％～15％。
[ Objective ] In order to study the effects of organic fertilizer mixed pesticide application in paddy field, analyze effects on soil structure, economic characters and yield of rice. [ Method] The comparison method was adopted. [ Result] The results showed that in the case of conventional rice fertilization, add to applying 750 kg/hm^2 organic fertilizer mixed pesticide per mu can effectively reduce the soil bulk density, improve the economic characters and yield of rice. [ Conclusion ] Therefore, it was considered that applying organic fertilizer mixed pesticide could improve soil structure, increase rice production and reduce the amount of fertilizer 10% -15%. Key words Organic fertilizer mixed pesticide; Rice; Soil bulk density
