针对4种不同土壤改良措施改造的油茶低产林的土壤养分,酶活性进行了测定和分析.结果表明:4种土壤改良措施都有促进土壤养分释放的功效,配合有机肥施入的土壤改良措施对促进土壤养分释放和提高土壤酶活最有效;无论土壤改良与否,4种土壤酶活的垂直分布基本一致,但酶活性强度明显变化;相关分析表明,土壤有机质,氨态氮,速效磷,速效钾与土壤过氧化氢酶,蔗糖酶,脲酶,磷酸酶酶活呈正相关关系,其土壤有机质含量与4种酶活呈极显著正相关;氨态氮与过氧化氢酶活性呈极显著正相关,与蔗糖酶活性和磷酸活性呈显著正相关;速效磷与4种酶活相关关系不显著;速效钾与过氧化氢酶活性呈显著正相关

The soil nutrients and soil enzyme activity were studied and analyzed for the four improved soil in the low-yield Camellia oleiferon stands.The results show that four types of soil improvement all improved soil nutrient release effectively,and adding organic manure to the soil in the soil improvement treatment had the most effective impact on improving soil nutrient release and activating soil enzymes.Whether soil improvement or not,the vertical distribution of soil enzymes activity in four kinds of soil was basically the same,but the intensity of enzyme activity changed greatly.Correlation an...
