Vegetable waste water-logged compost treatment method

Abstract

The invention discloses a vegetable waste water-logged compost treatment method which comprises the following steps: firstly, laying a greenhouse film at the bottom of a water-logged compost pool, sequentially adding dry soil and vegetable waste on the greenhouse film, spraying a decomposition microbial inoculum on the dry soil and the vegetable waste, and reserving a space with a certain height on the top surface of the dry soil at the top layer and the top of the water-logged compost pool; then covering a greenhouse film for reducing water-logged compost, then adding vegetable wastes and dry soil in a layered manner for continuously reducing water-logged compost, continuously repeating the step until the greenhouse film is 2 m higher than the ground, and covering the greenhouse film for continuously fermenting; carrying out deep tillage and pool pouring on the primary retting fertilizer, combining the retting fertilizer in the water-logged compost pool, fully stirring, and carrying out secondary fermentation on the incompletely decomposed part; and digging out the rotten vegetable residue biological fertilizer after fermentation and decomposition, airing and crushing. According to the method, after reduction water-logged compost is firstly carried out, the rotten vegetable leaves and soil are added layer by layer for continuous fermentation, then secondary fermentation is carried out after deep ploughing and pool pouring mixing, the microbial inoculum water-logged compost effect can be achieved to the maximum extent, and the rotten vegetable leaves are large in treatment amount, low in cost, short in period and high in utilization rate.

Description

technical field [0001] The invention belongs to the technical field of vegetable waste treatment, and in particular relates to a vegetable waste retting treatment method. Background technique [0002] Vegetable waste, commonly known as tail vegetables, refers to wastes such as roots, stems, leaves, fruits and other wastes generated during the harvesting, circulation, and sale of fresh vegetables, as well as leftovers that cannot be transported and sold due to seasonal vegetable price fluctuations. The yield accounts for more than 35% of the vegetable yield. In 2020, the planting area of ​​vegetables in Dingxi City will reach 800,000 mu, and the output of tail vegetables will reach 950,000 tons. Restricted by technical and economic conditions, these end vegetables are piled up in large quantities in rural fields, in ditches, beside roads, in farmers' markets and other places, and have not been fully utilized. After the tail vegetables rot and deteriorate, they pollute the a...

Problems solved by technology

[0003] At present, the treatment of tail vegetables is mainly direct return to the field and feed. There is a risk of yield decline and quality deterioration in the direct return to the field, while the cost of feed is high and the treatment is difficult, which is not easy for the masses to accept.
