以连作3年的长豇豆土壤为对象，研究了不同来源的有机肥料对长豇豆连作土壤有机质、速效养分含量及土壤酶活性的影响。结果表明，在收获后施用鸡粪、猪粪为主的有机肥的土壤有机质含量、土壤有效N、P、K含量显著高于施用海产品残渣有机肥的；施用化肥的土壤有效N、P、K含量显著高于施用有机肥的。不同有机肥处理均提高了土壤pH值，而硫酸钾型复合肥处理使土壤pH值降低。土壤酶活性分析结果表明，在长豇豆的各生育期内，不同肥源有机肥处理均提高了土壤过氧化氢酶、脲酶、多酚氧化酶和蔗糖酶的活性，而化肥处理降低了土壤酶活性。在长豇豆采摘盛期，土壤酶活性最高，各处理间差异显著，其中，鸡粪处理效果最好，猪粪处理次之。

In order to study the effects of different fertilizers on soil nutrients and enzyme activities , the present study was conducted in the field , where asparagus bean was continuously planted for 3 years.It was shown that chemical fertilizers and organic manures could increase the content of soil organic matter , soil available nitrogen , phosphorus and potassium.Application of organic fertilizers could increase the soil pH , while chemical fertilizers significantly lowered soil pH.Compared with the control , organic fertilizers could increase the activity of the soil catalase , urease, polyphenol oxidase and sucrose , while the chemical fertilizer treatment decreased soil enzyme activity .In the harvest stage, soil enzyme activity reached the highest level , and the differences between the treatments were significant in this stage.Among all the fertilizers, the effect of chicken manure was the best , which was followed by pig manure .
