Description
Technical field
The invention belongs to agricultural plantation technology field, is related to agricultural fertilizer, and in particular to a kind of water-soluble fertilizer of green upgrading
Material and preparation method thereof.
Background technology
With the mankind to food needs be continuously increased and the continuous consumption of natural resources, for the available arable land face of the mankind
Product is constantly reduced, and the manure resources that can be exploited and synthesize constantly are reduced with raw material so that human needs ploughs in unit area
On produce more crops or cereal product.In order to improve unit area crop yield, the mankind continually develop drought soil
Utilization, establish irrigating facility in these regional and original rain-fed agriculture regions, carry out the irrigable culture technology such as drip irrigation and sprinkling irrigation, adopt
With the Integration of Water into Fertilizer, reach province's fertilizer, water-saving, saving of labor and the effect for improving crop yield, realize crop yield and quality
General Promotion.With the development of agricultural science and technology, farmland under irrigation is continuously increased, it was predicted that having to the year two thousand twenty whole nation farmland
Effect irrigated area will need water soluble fertilizer more than 25,000,000 tons up to 1,000,000,000 mu, and this just needs to provide battalion comprehensively for plant growth
Foster, function admirable, plant growth, fertilizer efficiency can be stimulated stable and lasting high-quality water soluble fertilizer.Water soluble fertilizer is that one kind can
With completely soluble polyelement composite fertilizer, it can be rapidly soluble in water, it is easier to is absorbed by crops, crop absorption rate
It is very high, the irrigating facilities such as drip irrigation and spray irrigation agricultural is can apply to, is unique necessary to realize water-fertilizer integral agriculture cultivation technology
Fertilizer type.Because water soluble fertilizer and water-soluble fertilizer practice can increase substantially utilization rate of fertilizer, compare Common compound fertilizer
Material is increased operation rate more than 1 times, therefore can realize economic and reasonable fertilization, reduces significantly dose, saves manure resources.
, many defects be present in current existing water soluble fertilizer technology：As including nutrient is not comprehensive, it is impossible to for crop or
Soil supplements organic nutrition or organic matter, available nutrient content are low, and nutrient structure is unreasonable, it is impossible to provides balanced support for crop
Point, effective ingredient is unstable after being manured into soil, easily leaching loss or volatilization loss, and fertilizer synergistic is not made after being manured into soil, is kept
Stable state, promotion plant growth and the effect that strengthens crop anti-adversity of the fertilizer in soil, it is required to be only to provide crop institute
Nutrient.So water soluble fertilizer utilization rate cannot get due raising.
Biogas slurry contains a certain amount of organic matter, a great number of elements, trace element, amino acid, vitamin etc..Can be not only to plant
Thing provides nutrient, may also reach up the effect of sterilization and pre- preventing disease and pest.Thus biogas slurry can be directly as fertilizer application, still
Its nutrient content is less, causes cost of transportation larger, and dissolves the soil of needs nearby far fewer than the yield of biogas slurry.Thus natural pond
Liquid is directly applied restricted larger as fertilizer.
The content of the invention
According to above the deficiencies in the prior art, the technical problems to be solved by the invention are to propose that a kind of green upgrading is water-soluble
