Embodiment 1

[0058] The method of using OTC to regulate the form of complex heavy metals in domestic waste composting:

[0059] (1) Under natural light, the treatment groups are:

[0060] 125g garden soil + 25g compost (I);

[0061] 150g garden soil + 20mmol / kgOTC (Ⅱ);

[0062] 125g garden soil + 25g compost + 20mmol / kgOTC (Ⅲ);

[0063] Mix well and put it into a plastic containerΦ 上口径 =6.8m,Φ 底 =4.8cm, h=7.4cm, and put on a paper cup;

[0064] (2) Divide the surface of each plastic container into two parts, sprinkle 0.25g of tall fescue seeds soaked 24 hours in advance on one half, water twice a day in the morning and evening, and water 4-6ml at a time to meet the needs of plant growth; The seeds were placed in a dark place in the previous week to promote seed germination, and the soil samples in the cups were taken respectively on the 7th, 21st and 35th days after the seeds germinated after OTC exposure, and the urease and catalase activities in the soil were measured and analyzed; ...

Abstract

The invention discloses a method for cooperatively controlling garden soil enzyme activity by adopting OTC (oxytetracycline) and compost. According to the method, the OTC and the urban refuse compost are utilized for cooperatively controlling the soil enzyme activity of gardening modeling plants, so that the aims of inhibiting the growth of ornamental plants in the gardening plant landscape and reducing the management cost are realized. The steps are mainly as follows: sowing 0.25 g of festuca arundinacea seeds, which are soaked for 24 hours in advance, on half of a vessel, which is filled with 125g of garden soil, 25 g of compost and OTC of 20 mmol/kg, respectively sampling the soil in a cup when the OTC is exposed, namely on the seventh day, the twenty-first day and the thirty-fifth day after seed germination, and carrying out measurement analysis on the activity of urease and catalase in the soil.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to a method for synergistically regulating garden soil enzyme activity by using oxytetracycline (OTC) and compost. Background technique [0002] Household garbage is a general term for the solid waste discharged in the daily life of urban people. Composting technology is mostly used in the treatment of urban household garbage in my country. Municipal solid waste compost contains phosphorus, nitrogen, potassium and organic matter and other nutrients needed for plant growth, and can be used as organic fertilizer in agriculture. The nutrients in the garbage compost can increase the organic matter content of the nutrients by 11.81%-72.12%. Studies have shown that the application of domestic waste compost can significantly increase the yield of Chinese cabbage. The study found that using domestic waste compost as a substrate to plant tea trees increased production by abou...
