湿垃圾来源的蚯蚓粪肥对连作障碍土壤质量和黄瓜产量的影响
Effects of Earthworm Manure Fertilizer Produced by Wet Waste on Continuous Cropping Obstacles on Soil Properties and Yield of Cucumis sativus
摘要
Abstract
With the development of urbanization,the output of wet waste is increasing,and the resource utilization of wet waste is imminent.Using earthworm to treat wet waste to make earthworm manure for farmland soil improvement is an effective way of resource utilization of wet refuse and is conducive to alleviating the obstacles of vegetable continuous cropping.Earthworm manure made from wet waste and anaerobic biogas residue was selected as the study object.The effects of earthworm manure applied for three consecutive years on soil quality and crop yield of Cucumis sativus were studied.The results showed that after three years of improvement,the organic matter content and cucumber yield treated with 60.0 t/hm2 earthworm manure increased by 50.0%and 5.60%,respectively,and the effect of earthworm manure was higher than that of conventional organic manure.The soil total nitrogen content reached the highest level,which was 33.0%higher than the background value.The soil nutrient content(nitrate nitrogen,available phosphorus,available potassium)was also improved,and the available potassium content was increased by 94.0%.After 3 years of improvement,the number of bacteria in the soil increased significantly with the application of organic fertilizer,in which was the highest treated with 30.0 t/hm2 earthworm manure.The ratio of soil bacteria/fungi was increased,and the biological properties of soil were improved.The soil respiration intensity increased with the application of organic fertilizer,in which was the highest treated with 60.0 t/hm2 earthworm manure.Soil pH decreased slightly and salinity did not change significantly.Therefore,earthworm manure from wet waste can improve the physical,chemical and biological properties of soil,alleviate the occurrence of continuous cropping obstacles to a certain extent,and can be used as a substitute for chemical fertilizer or combined with chemical fertilizer to promote agricultural production.关键词
