Abstract
The invention provides a treatment method for phosphorus-enriched soil. The treatment method includes the steps that the phosphorus-enriched soil is ploughed; a soil remediation agent is evenly spread to the ploughed phosphorus-accumulated soil to be evenly mixed; and the evenly-mixed soil is irrigated, wherein the amount of water used for irrigation is the water-holding capacity required for crop plantation, and the remediation time is 25-38 days. A polyglutamic acid-kaolin intercalation composite material is used as the soil remediation agent, the raw material is high in biocompatibility, green and free of pollution, no burdens can be caused to the soil, and safety of crops is ensured; and the remediation agent is stable in performance and capable of easily and stably treating the polluted soil.
Description
Technical field
The invention belongs to soil remediation field, relate to a kind of administering method of phosphorus Enriching soil.
Background technology
Phosphorus is one of large element of three needed for plant growth, phosphorus in soil can provide basis for high crop yield high-quality, but in crop-planting process, peasant is in order to devote exclusive attention to output and economic benefit and heavy dressing, the consumption of fertilizer, considerably beyond the actual demand amount of crop, causes a large amount of accumulation of phosphorus in ploughing.
So-called enrichment state phosphorus refers to that phosphorus is not accumulated on the P elements in soil by crop utilization.Due to Use out of range chemical fertilizer, enrichment state phosphorus not only causes soil deterioration, also can enter earth's surface and body of groundwater by the approach such as runoff, seepage, threaten to ecological environment.And use in a large number containing phosphatic manure due to soil, the saturated of Soil Phosphorus element can be caused, cause the reduction of Soil Phosphate Absorbing Capacities amount, the percolation ratio increase of soil phophorus is present in soil in a large number, become the key factor of restriction agricultural productive force.
Current domestic soil remediation is in the starting stage, and on market, product efficacy is uneven.Phosphorus Enriching soil repairing and treating method is a lot, comprises engineering measure, biological prosthetic etc.The measures such as engineering reparation mainly takes soil removal and replacement to phosphorus Enriching soil, deep ploughing is digged, the method pollution administration is effective, but quantities is huge, investment cost is far beyond crop profit, destroy soil structures, cause soil fertility to decline, the stacking of contaminated soil can cause secondary pollution.Existing soil-repairing agent also exists repairing efficiency length, easily produces secondary pollution, the shortcomings such as DeGrain.Biological prosthetic is utilize plant from soil, absorb P elements or adopt the P elements near microorganism adsorption root system, phytoremediation can not cause secondary pollution, cost lower, therefore extensive concern is subject to, but due to the biological prosthetic cycle long and short time DeGrain, the reasons such as plant absorption mechanism is indefinite, are not biological prostheticly applied on a large scale.
Summary of the invention
It is short that the technical problem to be solved in the present invention is to provide a kind for the treatment of cycle, the phosphorus Enriching soil administering method that applied widely, cost is low.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of administering method of phosphorus Enriching soil, comprises the following steps: (1) ploughs plough phosphorus Enriching soil, and the cultivated plough degree of depth of described soil is 25-30cm;
(2) evenly sowed by soil-repairing agent in the accumulation phosphorus soil to cultivated plough and mix, the amount of application of every mu of accumulation phosphorus soil is 150-300g;
(3) irrigate the soil mixed, irrigate institute's water consumption water-holding capacity needed for long-term cropping, repair time is 25-38 days.
Further, described soil-repairing agent is polyglutamic acid-kaolin intercalation composite.
Further, in described soil-repairing agent, polyglutamic acid and kaolinic mass ratio are 0.5-0.8:1.
As preferably, the amount of application of described soil-repairing agent in described accumulation phosphorus soil is 200-220g/ mu.
Further, when described soil-repairing agent is evenly sowed, it is sowed the degree of depth and soil and ploughs that to plough the degree of depth identical.
Compared with prior art, the present invention has following beneficial effect:
(1) adopt polyglutamic acid-kaolin intercalation composite as soil-repairing agent, this raw material good biocompatibility, green non-pollution, can not cause burden to soil, ensure that the security of crop; This healer properties is stablized, and is easy to stabilization processes contaminated soil.
(2) soil remediation method provided by the present invention has treatment cycle short (25-38 days), applied widely, the features such as soil-repairing agent consumption is few, and cost is low.
(3) soil-repairing agent is directly sowed in soil, and the degree of depth is only 25-30 centimetre, in-situ immobilization, digs without the need to soil removal and replacement and deep ploughing, can not spoiled soil structure, and can not cause profound soil degradation, cost is low, effective.
