Description
Technical field
The invention belongs to technical field of fertilizers, and in particular to a kind of environment-friendly type fertilizer.
Background technology
Plant growth needs various nutrient elements, wherein, grand nutrition element required for plant growth include carbon, hydrogen,
Oxygen, nitrogen, phosphorus, potassium, calcium, magnesium and sulphur, micronutrient element include boron, copper, iron, manganese, molybdenum, zinc and chlorine etc..Fertilizer is the grain of crop
Food, the nutrient needed for plant growth will be supplemented by applying fertilizer.With fertilising for many years, soil hardening, acid are caused
Change, the problems such as heavy metal accumulation.In addition with the fast development of economy and the progress of industrial technology, work, agricultural production are to environment
Harmful effect constantly aggravate, solid waste constantly to soil surface stack and topple over, harmful waste water constantly permeates into soil,
Pernicious gas and floating dust in air are also constantly dropped in soil with rainwater, also result in the heavy metal pollution of soil.Wherein,
Heavy metal pollution of soil turns into the protrusion environmental problem that can not be ignored, and farmland soil heavy metals pollution has huge harmfulness,
Heavy metal in soil pollution can not only cause crop production reduction and quality decline, can also be by soil-plant system, through food chain
Enter people's human body, be detrimental to health and life security, the report of the harm of the heavy metal pollution such as cobalt rice, antimony poison, blood antimony in recent years is repeatly
See not fresh, there is very big harm to realize.Heavy metal pollution of soil has hysteresis quality, chronicity and the biology of disguised harm
The features such as biological concentration of chain heavy metal, if these decide that difficulty will be brought by recognizing heavy metal pollution of soil and administer hysteresis
With the serious consequence of expectation.Such as 20th century in Japan's generation because Cd pollutions in farmland cause " itai-itai " environmental hazard to be exactly most allusion quotation
The example of type.China's Farmland Soil Pollution is on the rise, and the report of the heavy metals exceeding standard such as soil, rice, vegetables sees report again and again
End, relevant information show that China in 1998 is accounted for the 1/ of total area under cultivation by nearly 20,000,000 hectares of the cultivated area of heavy metal pollution
5.Cause annual more than 1,000 ten thousand tons of grain drop in production, contaminated grain adds up to economic loss up to 20,000,000,000 yuan ten thousand tons up to more than 1200.
The problems such as ecological negative effect, agricultural product security, health and Green Trade Barrier for being triggered by heavy metal pollution, has caused wide
General concern.Therefore under such major premise, how study reduces heavy metal pollution, improved soil, improves the utilization rate of fertilizer, from
And reach Ecological Sustainable Development, the edible safety of crop is lifted, to agricultural planting, there is important meaning in terms of ecological environment
Justice.
