The remediation method provided by the present invention uses the soil remediation agent and chemical fertilizer mixed hole fertilization, wherein the amount of conventional base fertilizers for vegetables per hole is reduced by 1/2-2/3, the remediation agent and the chemical fertilizer are mixed to be used as a base fertilizer in the way that 2 g of the remediation agent is used in solanaceous vegetables per hole, and 3-5 g of the remediation agent is used in melon and fruit vegetables per hole, the mixture of the chemical fertilizer and the remediation agent should be prevented from being too close to roots of vegetable seedlings, roots of vegetable shall can not be in contact with fertilizers, and vegetables are fully watered or irrigated after transplantation.
Description
Technical field
The present invention relates to soil-repairing agent, particularly relate to the special renovation agent of a kind of vegetable field soil and restorative procedure, belong to the novel environment friendly applied technical field that rational sampling quantity of protected vegetable culture point-source pollution controls.
Background technology
Vegetables are farm crop that China's cultivated area is larger, and vegetable basket is the people's livelihood engineering of governments at all levels and citizen's general concern, and vegetables quality security implication everyone life, and the soil producing vegetables is directly connected to quality of vegetable and safety.But, along with a large amount of uses of fertilizer and pesticide, China's vegetable plot pollution problem is severe, greenhouse vegetable soil point-source pollution injures ecotope, food safety and people ' s health, as calendar year 2001 Ministry of Agriculture vegetables Product Quality Verification Centers to the whole nation 17 big cities, 10 kinds of vegetables, 181 sample quality inspection results are announced: qualification rate is 52.5%, and disqualification rate reaches 47.5%; Particularly nitrate recall rate 100%, its exceeding standard rate also reaches 100%; Also has the power and position department warning of domestic and international vegetable nutrient research: " NO3-N and NO2-N that the mankind take in has more than 80% to derive from vegetables, is one of maximum killer of carcinogenic disease ".Although these data have been pass by more than 10 year, can the specific aim product of dealing with problems at home also seldom, vegetable field soil pollution problem is still severe, and as pollution administration of not adopting an effective measure, rehabilitating soil, quality of vegetable is difficult to promote, and people ' s health safety is troubling.Therefore, vegetable field soil is repaired extremely urgent.
It was gratifying, China scientific and technical personnel make great efforts for this reason, and " biozeolite reactor " technology of environmental protection doctor of science Mrs Wen Donghui research, at water body ammonia nitrogen (NH
4 +), indelible contribution is made in eutrophication control aspect.As " biozeolite reactor " be natural zeolite gather around Na
+and Ca
2+nH in ion and polluted-water
4 +ion first exchanges, then NH
4 +be adsorbed in zeolite, along with microorganism is the NH of zeolite adsorption
4 +nitrogen (NO is converted into by heterotrophic nitrification/aerobic denitrification
- 2-N), get rid of from water body, control the ammonia-state nitrogen eutrophication of water body with this iterative cycles method.2012.11.07 Chinese patent CN 102764759 A discloses " a kind of reparation medicament for administering As polluted soil and using method ", and specifically discloses that " repair kit containing following raw material, its mass percent is: oxygenant is 5-30%; Fe-base compound is 30-70%; Mineral material is 10-60%; Each raw material is ground into respectively granularity and be not less than 200 object materials, mix in proportion ".This patent, mainly for heavy metal contamination, cannot repair the soil of pollution by chemical fertilizer.
In order to solve this present situation as possible, the application have developed a kind of novel environment friendly product-" soil-repairing agent ", the application adopts fermenting agent, zeolite powder, cake powder, humic acids and brown sugar are raw material, process by fermentation, scientific compatibility forms, this product and " biozeolite reactor ", the unique beneficial environmental properties both utilizing microorganism various functions effect only and natural zeolite physical and chemical performance is basic simlarity, " biozeolite reactor " relates to water body field, the ammonia-state nitrogen eutrophication of major control water quality, and this product relates to remediation contaminated soil field, the accumulation of NO3-N and NO2-N in major control soil, reduce carcinogenic content in vegetable products.
Document retrieval finds, with fermenting agent, zeolite powder, cake powder, humic acids and brown sugar for raw material, and the special renovation agent of the vegetable soil through fermentative processing, scientific compatibility and restorative procedure is domestic there is not yet relevant report.
