Description
Technical field
The present invention relates to soil pollution technical field, specially a kind of restorative procedure of Farmland Soil Pollution.
Background technique
Soil be not only earth ecology circle important component and important natural resources for the survival of mankind it
One, with the rural activities such as the industrial activities such as exploitation of mineral resources, smelting and sewage irrigation, applying sludge and chemical fertilizer inferior into
Row, the harmful heavy metals such as Cd, Pb constantly enter in soil environment, pollute to normal production and living.Therefore, soil is administered
Heavy metal pollution to conservation culture set and the life of human health is of great significance.
The long-term cropping in contaminated soil, not only will affect plant growth, to reduce crop yield, while can also make
Crop absorbs the ingredient in contaminated soil during the growth process, makes harm of the crop by heavy metal deposition itself, thus human body
Adverse effect can also be generated after eating above-mentioned crop, lead and its compound respectively organize human body toxic, inhale through alimentary canal
It receives, is poisoned into blood circulation.
Heavy metal and many teleorganic nutrients influence each other the Function of both sides, and extra-nutrition element can subtract
The toxic action of heavy metal in light crops, silicon, selenium, nitrogen, phosphorus, potassium, calcium, magnesium and some microelements are the beneficial of crops
Element can not only hinder the accumulation of heavy metal in control crops using foliage-spray, also to a certain extent as physiology barrier
Crop growth, yield can be promoted to increase, quality improving, therefore we have proposed a kind of restorative procedures of Farmland Soil Pollution to come
It solves the above problems.
