Description
Technical field
The present invention relates to field of agricultural cultivation, and in particular to a kind of organic materials quantization recommendation of prevention field of vegetables pollution of area source
Fertilizing method.
Background technology
The Yellow River and Huai He River sea region is that facilities vegetable plantation and feces of livestock and poultry cultivate scale, the higher region of intensive degree,
It is heavier one of the region of facilities vegetable main producing region agricultural non-point source pollution.On the one hand, aquaculture generates a large amount of feces of livestock and poultry, harmless
Field of vegetables application is one of main utilization ways of organic materials after change processing；On the other hand, it is needed in facilities vegetable plantation a large amount of
Npk nutrient, organic fertilizer has the characteristics that culture fertility, nutrient supply are slow, played extremely in terms of field of vegetables soil fertility cultivation
Important role.Currently, existing recommendation organic materials dosage with play organic materials culture fertility effect based on, emphasize to apply
More soil fertility are higher, but the npk nutrient amount that organic materials is brought into does not calculate quantitatively to fertilizing systems total nutrient amount,
Excessively application causes nitrogen phosphorus amount of nutrients in nitrogen phosphorus nutrient accumulation, especially feces of livestock and poultry and organic commercial fertilizer high to fertilizer, organic fertilizer
The nitrogen phosphorus total nutrient content of input in the soil, causes nitrogen phosphorus risk of phosphate leaching loss, has aggravated dish far more than crop nutrition content demand, accumulation
Field the degree of non-point source pollution, year after year plant after, field of vegetables yield and quality reduce, soil nitrogen phosphorus accumulation, be more than soil nitrogen phosphorus agronomy and
Environmental threshold value causes soil nitrogen phosphorus leaching loss, polluted underground water environment to cause pollution of area source, seriously restrict the facilities vegetable place of production
Clean environment and Green Sustainable.
Invention content
To solve the above problems, the present invention provides a kind of organic materials of prevention field of vegetables pollution of area source to quantify fertilization recommendation
Method recommends the fertilizer index and method of organic materials dosage with nitrogen, phosphorus amount, according to crop nutrition content uptake, soil fertility water
It is flat, establish organic materials quantization fertilization recommendation nitrogen phosphorus nutrient fertilizer index and organic-inorganic with ratio is applied, stringent control has
The nitrogen phosphorus otal investment of machine material and chemical fertilizer, from source and planting process, two links effectively reduce soil nitrogen phosphorus accumulation, reduce
Field of vegetables nitrogen phosphorus pollution of area source risk, technical support is provided for field of vegetables Ides On Prevention And Control of Regional Pollution.
To achieve the above object, the technical solution that the present invention takes is：
