摘　　要：通过田间小区试验,研究不同秸秆腐熟剂对早稻秸秆腐解程度、土壤理化性状以及晚稻产量和产量构成因素的影响,并分析了不同处理间的经济效益。结果表明:早稻秸秆还田添加腐熟剂由于加速了稻草腐解速率、促进了稻草养分释放,从而提高了土壤肥力,改善了土壤理化性状,有利于晚稻生长以及产量构成因素的形成,进而增加了稻谷产量,对经济效益增加也有一定的效果。在4种供试腐熟剂产品中以"覆垄丰"有机物料腐熟剂和"施瑞福"牌腐秆剂的施用效果较好。through the field test, study the influences of different straw decomposition maturing agent on the decomposition degree of early season rice straw, soil physical and chemical properties, and rice yield and yield component factors, also analyzes the economic benefits among different treatments. The results showed that returned the early season rice straws to the fields and added the decomposition maturing agents, because accelerated the decomposition rate of rice straw, boosted the straw nutrient release, then improve soil fertility, improved soil physical and chemical properties, benefited the formation factors of the growth and yield of late rice, increase the yield of rice in the husk, has a certain effect to increase the economic efficiency. In 4 kinds of decomposition maturing agent products for testing, the application effect of ＂Fu Long Feng＂ the organic material decomposition maturing agent and ＂Shi Rui Fu＂ the stem decomposition agent is better.
