摘要：施用有机肥是盐碱土改良与培肥地力的有效方式。选鸡粪和木醋液为改良剂,通过土壤培养试验,研究未施肥(CK)、单施鸡粪(CM)、单施木醋液(PA)、鸡粪+木醋液配施(CP)共4个处理对滨海盐碱土化学性质和酶活性的影响。结果表明:与CM相比,CP处理的pH值显著降低0.34个单位,电导率(EC)降低14.52%。与PA相比,施用鸡粪处理(CM和CP)的土壤养分含量和酶活性均显著提高。CP的全氮、有效磷、水溶性有机碳、水溶性有机氮和硝态氮含量较CM分别高出55.32%、103.35%、16.64%、55.68%和45.43%;而土壤α-葡萄糖苷酶、β-葡萄糖苷酶、几丁质酶、亮氨酸氨基肽酶、碱性磷酸酶、多酚氧化酶和脱氢酶活性分别显著增加49.58%、67.85%、40.84%、104.94%、17.66%、62.05%和37.50%。回归分析表明,土壤有机质、全氮、有效磷和水溶性有机碳、氮含量的增加促进酶活性的提高。综上所述,鸡粪与木醋液配施可显著降低盐碱土的pH值,并能显著提高盐碱土养分含量和酶活性。
Organic fertilizer is an effective way to alleviate the degree of soil salinization and improve soil fertility. In order to evaluate the impact of manure treatment on chemical properties and enzyme activities of coastal solonchak soils, the manipula- tions composed of coastal solonchak soil （CK）, chicken manure （CM）, pyroligneous acid （PA） and chicken manure co - applied with pyroligneous acid （CP） were conducted by using soil culture method. The results indicated that soil pH and EC value under CP significantly decreased by 0. 34 and 14. 52% in comparison with CM. The nutrient contents and enzyme activi- ties of coastal solonchak soil by applying chicken manner （ CM and CP） were significantly higher that under PA treatment. Compared with CM treatment, the concentrations of total nitrogen, available phosphorus, dissolved organic carbon, dissolved organic nitrogen and nitrate nitrogen under the CP treatment significantly increased by 55.32%, 103.35%, 16. 64%, 55.68% and 45.43 %, respectively ; Meanwhile, the activities of a-glucosidase, [3-glucosidase, 13-N-acetylglucosaminidase, leucine aminopeptidase, alkaline phosphatase, polyphenol oxidase and dehydrogenase increased by 49.58%, 67. 85%, 40. 84%, 104. 94%, 17. 66%, 62. 05% and 37. 50%, respectively. Regression analysis indicated that higher contents of organic matter, total nitrogen, available phosphorus, dissolved organic carbon and dissolved organic nitrogen enhanced soil enzyme activities, in conclusion, chicken manure co-applied with pyroligneons acid alleviated pH, improved nutrient content and enzyme activities of coastal solonchak soils.
