Embodiment 1

[0038] Yuzhong jinyaweicai overburden buried pressure test site

[0039] (1) Selection of buried pressure test site for tailing vegetable covering soil:

[0040] Jinyaweicai overburden pressure field is located in bashigou (104.07 ° e, 35.91 ° n, 1938m above sea level), Jinya village, Jinya Town, Yuzhong County. The annual average temperature is 9.1 ℃, the annual precipitation is 400mm, and the annual evaporation is 1343mm. The soil type is loess. The specific type is gray calcium soil light gray calcium soil. The soil pH is 8.8. Before the experiment, the contents of nitrate nitrogen and ammonia nitrogen in 0 – 10cm, 10 – 20cm and 20 – 30cm soil layers are 0.9mg kg respectively –1 、7.0mg kg –1 、6.0mg kg –1 And 0.6mg kg –1 、1.0mg kg –1 、0.8mg kg –1 。 1.5 mu of wasteland is selected as the buried pressure test site of tail vegetable covering soil (such as Figure 2 a) , from September 4 to 11, 2020, it was found that there was no trace of groundwater (e.g Figure 3 )；

Abstract

The invention relates to an environment-friendly method for repeatedly using a residual vegetable soil covering and burying treatment site. The method specifically comprises the following steps: (1) selecting a residual vegetable treatment site; (2) repairing an approach road; (3) earth work of the soil covering and burying treatment site for the rotten vegetable leaves; (4) pulling and transporting the rotten vegetables; (5) soil covering and burying operation of the rotten vegetable leaves; (6) post-maintenance of the treatment site; (7) detecting odor, soil heavy metals, pesticide residues and soil moisture of the treatment site; and (8) repeatedly using engineering measures in a treatment site. The method provided by the invention has the beneficial effects that a large-quantity, rapid, low-cost, simple and feasible efficient treatment technology for the rotten vegetable leaves is provided, and the effects of rapidly treating the rotten vegetable leaves in a large quantity, inhibiting the emission of soil odor, avoiding soil heavy metal and pesticide residue pollution, avoiding underground water pollution and improving the repeated use effect of a treatment site are realized.

Description

technical field [0001] The invention relates to the technical field of efficient treatment and resource utilization of agricultural waste, in particular to an environment-friendly method for repeatedly using tail vegetables to cover soil and bury pressure treatment field. Background technology [0002] Gansu is the main producing area of "summer dishes on the plateau" in China and the largest production and distribution center of "transporting food from the north to the South and transferring food from the west to the East". Yuzhong County of Lanzhou is the main production base of summer dishes on the plateau in Gansu. It is located in the west of the Loess Plateau in western Gansu. Most areas in the territory are hills and basins covered with loess with an altitude of 1500-2500m, and the thickness of loess can reach 30-100m. In Yuzhong County, vegetable residues / vegetable wastes (tail vegetables for short) generated from field and circulation links are calculated in millions o...
