利用生物有机肥治理设施蔬菜土壤退化试验

Test on Using Bio-Organic Fertilizer to Control Soil Degradation of Facility Vegetables

摘要: 随设施栽培蔬菜的快速发展，长期、过量施用无机化学肥料也带来了一系列的土壤退化问题，有机质缺乏导致的土壤板结、容重增加、盐分过高引起的盐害等日益加剧。本试验设置增施生物有机肥处理，尝试解决土壤退化问题。研究证明：随增施生物有机肥量的增加，障碍土壤的有机质、容重和水溶性盐等指标均得到改善，而且呈正相关比例。但在考虑到成本投入的情况下，施用无机肥料 + 生物有机肥200 kg处理增收1295元/667m²，增收最高。

Abstract: With the rapid development of protected vegetable cultivation, long-term and excessive application of inorganic chemical fertilizers has also brought a series of soil degradation problems. Soil compaction caused by lack of organic matter, increase in bulk density, and salt damage caused by excessive salinity have become more and more serious. This experiment set up additional application of biological organic fertilizer treatment to try to solve the problem of soil degradation. Studies have shown that with the increase in the amount of bio-organic fertilizer, the organic matter, bulk density and water-soluble salt of the obstacle soil have been improved, and they are in a positive correlation ratio. However, taking into account the cost input, the application of 200 kg of inorganic fertilizer + biological organic fertilizer will increase income by 1295 yuan/667m², which is the highest increase.
