摘要
为了探讨湿垃圾堆肥产品施用方式对土壤理化性质的影响,本研究以上海市闵行外环林带为对象,通过分析沟施、撒施及对照3种处理的土壤容重、pH、EC、有机碳、全氮、有效磷、速效钾和全盐量的变化,评价不同施用方式对土壤肥力质量的影响。结果表明:与CK相比,施用湿垃圾好氧堆肥产品1个月后,不同土层土壤的pH均降低,EC、有机碳、全氮、有效磷、速效钾均增高,其中撒施处理显著提高了0~5 cm土层土壤EC、有机碳、全氮、有效磷、速效钾含量,沟施处理显著提高了5~30 cm和30~60 cm土层土壤EC、有机碳、全氮、有效磷、速效钾含量。土壤肥力质量评价结果表明:施用湿垃圾堆肥产品1个月后,不同施用方式处理的土壤质量均得到提升,其中沟施处理对30~60 cm土壤质量提升优于撒施处理。该研究为湿垃圾堆肥产品合理利用于绿林地土壤改良提供了依据。
In order to explore the effect of the application method of compost products of food waste on the soil,a field experiment was carried out outer ring forest belt of Minhang in Shanghai,to investigate the effects of compost products of food waste being applied with two methods of furrowing and broadcasting on the soil bulk density,pH,EC,organic carbon,total nitrogen,available phosphorus,available potassium and total salt,and evaluate the effects of different application methods on soil fertility quality,with no compost products of food waste as control.The results showed that soil pH decreased,and EC,organic carbon,total nitrogen,available phosphorus,and available potassium increased in different soil layers after applying food aerobic composting products for one month compared with CK.The content of soil EC,organic carbon,total nitrogen,available phosphorus,and available potassium of broadcasting treatments significantly increased in the soil layer of 0~5 cm.The furrowing treatment significantly increased the soil EC,organic carbon,total nitrogen,available phosphorus and available potassium in layers of 5~30 cm and 30~60 cm.The soil-fertility-quality evaluation results showed that the soil quality of different application methods improved after applying food waste compost products for one month,and the soil quality improvement of furrowing treatment to 30~60 cm was better than that of broadcasting treatment.The study provides a basis for the rational utilization of food waste compost products to improve green forest soil.
