摘要
通过大田试验研究了不施有机肥(CK)、施用平菇栽培废料(T1)、施用干腐熟牛粪(T2)和烘干鸡粪(T3)在种植黄瓜01-50 d内土壤中活性有机质和4种土壤酶活性的变化。结果表明:施入不同有机肥对土壤总有机质含量的影响为烘干鸡粪〉平菇栽培废料〉干腐熟牛粪〉对照;对活性有机质含量的影响为平菇栽培废料〉烘干鸡粪〉干腐熟牛粪〉对照;施用平菇栽培废料的土壤中脲酶、转化酶和脱氢酶活性最高,施用干腐熟牛粪的土壤中过氧化氢酶活性最高。相关性分析显示,脲酶、转化酶和脱氢酶活性与土壤活性有机质显著相关。用平菇栽培废料做有机肥能有效提高土壤活性有机质含量和土壤酶活性。
The labile organic matter and enzyme activities of urease, invertase, catalase and dehydrogenase were studied in soils treated with no organic fertilizer(CK), with waste culture material of Pleurotus ostreatus (T1), dried composted cattle dung (T2) and dried chicken manure (33) during the growing period of cucumber (0-150d). The results showed that different fertilizers had different effects on the contents of total organic matter, following the order from high to low: dried chicken manure, waste culture material of Pleurotus ostreatus, dried composted cattle dung and control. For the effects on the contents of labile organic matter, the order was waste culture material of Pleurotus ostreatus 〉 dried chicken manure 〉 dried composted cattle dung 〉 control. Enzyme activities of urease, invertase, and dehydrogenase in soil treated with waste culture material of Pleurotus ostreatus were the highest, and the enzyme activity of catalase was highest in soil treated with dried composted cattle dung. Labile organic matter showed significant positive correlations with the activities of urease, invertase, and dehydrogenase. It was concluded that the content of labile organic matter and soil enzyme activities could be improved efficiently when waste culture material of Pleurotus ostreatus was used as organic fertilizer.
