Embodiment

[0044] In 2018, the soil of flue-cured tobacco in the Sayingpan Tobacco Area of ​​Luquan County, Kunming City was improved for 10 years, and in 2019, a comparative test of flue-cured tobacco planting was carried out on the same plot before and after improvement. The soil improvement process is as follows:

[0045] S100: Mix marigold stalks and marigold flower waste with human and livestock excrement and urine (human and livestock excrement and urine account for 20% by volume), and then cover the mixed raw materials to form a decomposed state with a water content of 20-30%.

[0046] S200: Add polyhalite (mainly composed of potassium and magnesium sulfate fertilizer) evenly in the amount of 15Kg / m3 to the raw materials in the decomposed state formed above, and mix well to obtain a mixture for use.

[0047] S300: In autumn, winter or spring and other rainy seasons, plow the pre-repaired degraded soil for 25-30 cm before composting to form a relative humidity of 13-25% in the soil ...

Abstract

The invention discloses a degraded soil ecological simulation land maintenance restoration method which comprises the following steps: mixing any one of crop straws, dry branches and fallen leaves, weeds, humus soil and plant ash with human and animal excrement and urine, and stacking to form a semi-decomposed or decomposed raw material; adding a calcium magnesium phosphate fertilizer, a potash magnesium sulphate fertilizer, polyhalite and/or mineral powder into the semi-decomposed or decomposed raw materials, and uniformly stirring to obtain a mixture; stacking the mixture on the surface of the soil according to a ratio of 300-1000m <3>/mu, flattening, patting, compacting, covering with a film, and stacking; stacking the mixture for at least three months, removing the covering film to obtain a secondary fermentation fertilizer, and then removing at least 98% of the secondary fermentation fertilizer on the surface of the soil to complete remediation of the degraded soil. According to the method, a semi-decomposed or decomposed mixture covers the surface layer of the soil, a special isolation layer is formed by the mixture in a mode of forming humus soil in a simulated nature forest, and the purpose of restoring the soil fertility of the degraded soil is achieved through natural stacking and secondary fermentation treatment.

Description

technical field [0001] The invention belongs to the technical field of land restoration, and in particular relates to an "ecological simulation" restoration method for degraded soil with simple operation, low cost and good restoration effect. Background technique [0002] Soil water and fertilizer retention performance is an important indicator to measure the health of the soil. Tobacco planting soil, Panax notoginseng planting soil, etc., due to continuous cropping, lead to soil degradation phenomena such as soil fertility decline, structural deterioration, increase in the number of pathogenic bacteria, and decrease in the number of beneficial microbial groups. The final performance is that the water and fertilizer retention performance of the soil is reduced, and the growth and appearance of crops are hindered. The production and quality of tobacco leaves and Panax notoginseng declined. Therefore, in the production of crops such as tobacco leaves and Panax notoginseng, it...
