Abstract
The invention discloses concentrated biogas manure liquid nitrogen. The concentrated biogas manure liquid nitrogen comprises urea, wherein ammonium nitrate and biogas manure concentrated liquid are added into the urea; the weight ratio of the urea to the ammonium nitrate is 18:23; the N content in the concentrated biogas manure liquid nitrogen is not less than 30%; and the biogas manure concentrated liquid is prepared by removing 80% of water content from the biogas slurry using a biogas slurry membrane by means of concentration and separation. The concentrated biogas manure liquid nitrogen disclosed by the invention is practical, low in production cost, convenient in use, good in fast-acting property, long in lasting period, and obviously improved in effect; the biogas manure is well utilized to make waste profitable and provide a high-quality fertilizer to pollution-free agricultural production; the mouth feel and quality of crops can be effectively improved; and the water separated in the production process can be recycled as common domestic water.
Description
Technical field
The present invention relates to a kind of fertilizer, particularly the fertile liquid nitrogen in a kind of concentrated natural pond.
Background technology
At present, people, in planting process, generally can use urea or other compound as fertilizer sources, and urea as fertilizer sources, also exists certain deficiency and defect.
Common urea only possesses the basic function of nitrogen element, belongs to quick acting fertilizer, and the time length is short, and fertilizer efficiency is low.The utilization ratio of urea, in 30%-40% left and right, is not fully utilized simultaneously.
Some natural pond liquid in life, people's general processing mode is in as fertilizer sources use or as refuse treatment, natural pond liquid is not reasonably utilized.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of concentrated natural pond fertile liquid nitrogen.
To achieve these goals, the measure that the present invention takes:
The fertile liquid nitrogen in natural pond, comprises urea, adds the fertile concentrated solution in ammonium nitrate and natural pond in described urea;
The weight ratio of described urea and ammonium nitrate is 18:23;
N content >=30% of the described fertile liquid nitrogen in concentrated natural pond;
The fertile concentrated solution in described natural pond is made for natural pond liquid is gone out to 80% moisture by natural pond liquid film concentrating and separating after.
Beneficial effect of the present invention: practicality, production cost is low, easy to use, and quick-acting is good, lasting period is long, fertilizer efficiency is significantly improved, and has well utilized natural pond fertile, turns waste into wealth, for pollution-less agriculture, produce fertilizer is provided, and can effectively improve mouthfeel and the quality of crop, isolated water in production process, can continue to use as common domestic water.
Embodiment
The fertile liquid nitrogen in a kind of concentrated natural pond, comprise urea, in described urea, add the fertile concentrated solution in ammonium nitrate and natural pond, the weight ratio of described urea and ammonium nitrate is 18:23, N content >=30% of the fertile liquid nitrogen in described concentrated natural pond, the fertile concentrated solution in described natural pond is made for natural pond liquid is gone out to 80% moisture by natural pond liquid film concentrating and separating after.
Layoutprocedure, by natural pond liquid film concentrating and separating technology, by concentrated 5 times of natural pond liquid (100 tons of natural pond liquid become 20 tons of concentrated solutions and 80 tons of water, separated water circulation use), isolates 80% moisture, obtains the fertile concentrated solution in natural pond.
In the fertile concentrated solution in natural pond, add urea and ammonium nitrate again, make the fertile liquid nitrogen in concentrated natural pond of N >=30%.
As: the fertile concentrated solution in natural pond that urea 360Kg+ ammonium nitrate 460Kg+ is quantitative, make 1 ton of fertile liquid nitrogen (N >=30%) in concentrated natural pond.
Two processing are established in test
Test Treatment Design:
Process one: on the basis of conventional fertilizer application, use 30% liquid nitrogen, each 100g, in seedling growth mid-term.Gather first two weeks each once, after dew is dry, and not strong morning of sunlight or at dusk even spraying in the tow sides of blade, dilute 600 times.
Process two, on the basis of conventional fertilizer application, use the fertile liquid nitrogen (N >=30%) in concentrated natural pond, usage is with processing one.
It is 20m that 3 repetition ，Mei community unifications are established in each processing of test
2, establish protection row.
Above-mentioned data show: use after the fertile liquid nitrogen in concentrated natural pond, yield of pakchoi rises, and compares with ordinary liquid nitrogen, and amount of increase in production is 7.3%.Field test finds to spray the fertile liquid nitrogen in concentrated natural pond, can promote Growth of Cabbage, mainly can make Plantula Brassicae chinensis plant height increase, and leaf look is enlarged afforested area.
Claims (4)
