Description
Technical Field
The invention relates to the field of soil remediation, in particular to a method for remedying air-overflowing slow-release type barren hardened soil.
Background
The soil hardening refers to the phenomenon that the surface of soil is poor in structure due to lack of organic matters, the structure is damaged and the soil is dispersed under the action of irrigation, rainfall and other external factors, and the surface of the soil is hardened under the action of cohesive force after drying. The main factors of soil hardening are about 7 aspects: 1. the farmland soil is sticky and heavy, the clay content in shallow clay of a plough layer is high, the plough layer is less than 20cm on average, capillary pores in the soil are few, and the ventilation, water permeation and temperature rise are poor, so that the surface layer of the soil is skinned; 2. organic materials are less input, organic fertilizers are not applied or straws are returned to the field, so that organic substances in the soil are not sufficiently supplemented, the organic matter content of the soil is lower, the physicochemical properties of the soil are deteriorated, the activity of microorganisms is influenced, the formation of a soil granular structure is influenced, and the soil is hardened due to too large or too small acidity and alkalinity; 3. plastic waste polluted mulching films, plastic bags and the like are not cleaned up and cannot be completely decomposed in soil to form harmful blocks; 4. the long-term single application of the fertilizer and the farmyard manure is seriously insufficient, the diazo light phosphorus-potassium fertilizer reduces the organic matters of the soil, and the humus can not be supplemented in time, so that the soil is hardened and cracked; 5. the structure of upper soil is damaged due to the influence of mechanical cultivation caused by agricultural measures such as pressing, turning and the like, the granular structure of the soil is damaged, only part of fertilizer applied to the soil every year is absorbed and utilized by crops in the season, and the rest of the fertilizer is fixed by the soil to form a large amount of acid salt deposition, so that the soil is hardened; 6. the toxic substance content in local underground water and industrial wastewater of the accumulated part of the harmful substances is high, and the surface soil is hardened due to excessive accumulation of the toxic substances by long-term irrigation; 7. after the rainstorm caused by water and soil loss and the rainstorm, fine soil particles in the surface soil layer are taken away, so that the soil structure is damaged; and the sticky particles and small particles are easy to form hardening after being precipitated and dried in water accumulation places or flow slow places.
For farmers in south China, the cultivated land area is limited, so that the cultivated land area of each household is small and the supply is not sufficient, but the cultivated land is repeatedly used all the time, so that organic matters in the soil are less and less, the soil is easy to harden after long-term use, the quantity of small sticky particles and the like in the soil is reduced after the hardening phenomenon, the soil is difficult to absorb when being watered or applied with water-soluble fertilizer, the soil is easy to lose without being absorbed, the soil remediation difficulty is large, the remediation efficiency is low, and the remediation cost is high
