Abstract
The invention relates to a poly-aspartic acid ecological water-soluble fertilizer which comprises the raw materials by weight percent: 5-20% of humic acid, 10-35% of urea, 0.1-1% of poly-aspartic acid, 10-25% of potassium dihydrogen phosphate, 5-15% of calcium superphosphate, 0-48.6% of magnesium sulfate, 1-2% of boric acid, 0.5-1.5% of ferrous sulfate, 0.1-0.5% of ammonium molybdate, 0.2-2% of ethylenediamine tetraacetic acid, 0.1-0.5% of caproic acid diethylamino alcohol ester and 0.1-0.5% of compound sodium nitrophenolate. to the invention, poly-aspartic acid is added to be taken as synergist of water-soluble fertilizer containing humic acid; nitrogen element and other nutrient elements in the fertilizer have good controlled-release function under the actions of chelation, dispersion, absorption and the like of poly-aspartic acid, so that all the nutrient elements stably exist in the liquid phase in a complexing state and are slowly released into the soil to be absorbed by the crops, and the absorption utilization rate of all the nutrient elements is higher; and the product has the functions of improving the organic content in the soil, adjusting the soil pH, improving the soil and the like at the same time. Furthermore, the product can be instantly and completely dissolved, is suitable for multiple applications such as leave surface splaying, spray irrigation, drop irrigation and the like.
Description
Technical field
The present invention relates to the water-soluble fertilizer technical field, is the ecological water-soluble fertilizer of a kind of poly aspartic acid specifically, the invention still further relates to the production method of this water-soluble fertilizer.
Background technology
Intensive, large-scale development along with China's agricultural; large-scale farm continues to bring out; the develop rapidly of flower industry and fancy horticulture; because water resources wretched insufficiency; drip irrigation; the water saving facilities such as sprinkling irrigation agricultural area enlarges rapidly, and the consumption purposes of water-soluble fertilizer is increasing, and the importance of water-soluble fertilizer is more and more highlighted.
Containing the humic acid water-soluble fertilizer is a kind of new-type fertilizer, include humic acid and other big or middle, trace element, being can be fully, water-soluble organic-inorganic polyvalent compound manure promptly, easier to be absorbed by crops, its absorption rate generally is 2～3 times of conventional fertilizer, but drip irrigation and spray irrigation, soilless culture, the soil pouring, leaf dressing etc.Most importantly contain the humic acid water-soluble fertilizer and can be applicable to the production of Effictive nuisancelless agricultural-food and other industrialized agriculture and other industry (such as the gardens industry, landscape planting etc.), realize the liquid manure one by spray, drip irrigation etc., reach water-saving and economize fertile saving of labor's usefulness, its society, economy and zoology benifit are very remarkable.
Poly aspartic acid is the synthetic water-soluble high-molecular substance of a kind of artificial bionic, has the characteristic of without phosphorus, nontoxic, nuisanceless and fully biodegradable, is a kind of internationally recognized " green chemical ".Poly aspartic acid has the effects such as extremely strong chelating, dispersion, absorption because containing the constructional feature of peptide bond and carboxyl isoreactivity group.Poly aspartic acid itself is not fertilizer, does not have the effect of fertilizer, but it in entering soil after, can greatly reduce the loss of nutritive element by the effect and the process that repeatedly repeat enrichment and discharge to nutritive element, improve the utilization ratio of fertilizer, thereby make fertilizer synergistic, crop yield.
Summary of the invention
Technical problem to be solved by this invention provides a kind of can the punching and executes, can spray again, drip irrigation etc.
OnePlant the ecological water-soluble fertilizer of poly aspartic acid, the present invention also provides the production method of this water-soluble fertilizer.
Technical problem of the present invention adopts following technical proposals to solve:
The ecological water-soluble fertilizer of a kind of poly aspartic acid is comprised of the raw material of following weight per-cent:
