Problems solved by technology
However, the extensive use of chemical pesticides and disinfectants not only destroys the soil ecological environment, but also poses hidden dangers to the quality and safety of agricultural products.
[0005] In recent years, bio-organic fertilizers have been popularized and applied because of their role in the prevention and control of soil-borne diseases by adding functional microorganisms. However, due to the serious problems of soil degradation in my country, especially soil acidification and salinization, Due to the long-term and slow effect of bio-organic fertilizers on the regulation of the soil environment, it is difficult to colonize functional microorganisms, the activity is poor, and the control effect is unstable. It is difficult to effectively solve the outstanding problems of continuous cropping obstacles

Embodiment approach
[0048] The specific on-the-spot implementation scheme of the present invention is as follows:
[0049] Step 1, clean up: clean up the ground part of the last stubble pepper from the processing plot;
[0050] Step 2. Sprinkle material: evenly sprinkle 1 ton / mu of restoration agent on the surface of the treated plot;
[0051] Step 3. Soil preparation: Use a tiller to evenly plow the soil of the treated plot to make the soil particles fine and uniform, and to mix the restoration agent with the soil evenly;
[0052] Step 4, ditching: open ditches around the treatment land, the depth of the ditch is more than 30cm, and leave an opening at one end of the land;
[0053] Step 5. Irrigation: pour water into the ditch at the open end of the plot until it is submerged 1 cm above the soil surface, and close the open end;
[0054] Step 6. Cover the soil surface with a 60-micron-thick greenhouse film, compact it with soil around it, and keep it for 15 days;
[0055] Step 7. Remove the film...

The invention discloses an ecological remediation method for facility economic crop planting obstacle soil and a remediation agent used in the method. The remediation method includes the following steps: cleaning the above-ground parts of preceding crops from a treatment land block, sprinkling the remediation agent onto the surface of the treatment land block, arranging the treatment land block byusing a cultivator, performing ditching around and in the middle of the treatment land block, performing irrigation to make the soil reach a maximum saturated moisture content, maintaining the maximum saturated moisture content for 15-25 days, uncovering a film, and performing rotary tillage on the soil. The remediation agent includes fresh silkworm excrement and fresh bagasse. The method and theremediation agent improve soil acidification and reduce salinization in a short time, a strongly anaerobic soil environment is formed by rapidly reducing soil redox potential, and pathogenic microorganisms in the soil are effectively killed, so that planting obstacles are eliminated, and the normal production of facility economic crops is guaranteed.
Description
technical field [0001] The invention relates to the technical field of soil ecological restoration, and specifically relates to an ecological restoration method and a restoration agent for facility economic crop planting obstacles, which can eliminate the comprehensive planting obstacles of facility economic crops at one time, and are specially used to overcome and eliminate crop continuous cropping obstacles. Background technique [0002] Vegetables are the second largest crops after grain in my country's planting industry. In recent years, the growth rate of my country's facility vegetable area has accelerated, and the proportion of facility vegetable cultivation area and output has increased year by year. In 2016, my country's facility vegetable cultivation area reached 3.915 million hm2 (58.72 million mu), and the facility vegetable output was 252 million tons. , output, and output value account for 21.5%, 30.5%, and 62.7% of my country's vegetable production, and the dev...
