Description

Trace element water-soluble composite fertilizer and preparation method thereof in a kind of fulvic acid
Technical field
The present invention relates to a kind of water soluble composite fertilizer, trace element water-soluble composite fertilizer in specifically a kind of fulvic acid And preparation method thereof.
Background technology
It is well known that China is an agricultural production big country, China has supported and accounted on arable land of the world less than 10% is accounted for The population in the world more than 20%, for the continuous volume increase of agricultural product and grain, the applying quantity of chemical fertilizer of China is increasing.China is current The fertilizer of large-scale use still falls within Common compound fertilizer or single chemical fertilizer, and composite fertilizer is roughly divided into shaping composite fertilizer and blending Type composite fertilizer.Include MAP, Diammonium phosphate (DAP), nitrophosphate fertilizer, potassium nitrate, potassium dihydrogen phosphate, ternary with shaping composite fertilizer multiple Hefei is several, and binary compound fertilizer nutrient formula is fairly simple.Mix type composite fertilizer refer to be granulated with finished product chemical fertilizer of simple substance or The fertilizer of person's directly blending, most of is secondary operation.The universal nutrient of composite fertilizer largely used at present is relatively fixed, water Dissolubility is not fine, and fertilizer efficiency is low, and the fertilizer efficiency duration is short, causes a large amount of wastes of fertilizer, and utilization rate of fertilizer is relatively low and long-term Chemical fertilizer largely is used, soil hardening is easily caused, soil depletion pollutes environment.
In order to improve composite fertilizer's fertilizer efficiency, sight is transferred in Water soluble fertilizer by everybody at present.Water soluble fertilizer is a kind of energy Enough it is dissolved completely in the multielement compound fertilizer of water, full Water soluble fertilizer non-relative to traditional calcium superphosphate, granulated compound fertilizer etc. Material and sustained release kind, because it has high instant, absorptivity, instant effect, without residue, using the remarkable advantage such as convenient, are obtained Swift and violent development.Especially in the environmental protection being on the rise brought in face of greenhouse effects and the situation of water resources shortage Under, drip irrigation system, spray sprinkling irrigation etc. there is significantly water saving, the novel fertilizer application mode of the fertile function of section to start to be widely applied, make Agricultural fertilizer person basic change to the noegenesis of fertilizer.Micronutrient levels is less in current water soluble fertilizer, fertilizer Material proportioning is unreasonable to cause fertilizer efficiency poor, and being used for a long time easily causes nutrient loss in soil, soil acidification, hardened, nitrogen, phosphorus, The plant recovery of nutrient such as potassium are not high, the problems such as soil fertility degradation, and agricultural sustainable development is by serious challenge.
The content of the invention
It is compound the invention provides trace element water-soluble in a kind of fulvic acid for problems of the prior art Fertilizer.Rationally, nutrient is balanced for the fertilizer formula, and good water solubility, rich in various trace elements and a large amount of beneficial microbes, can be improved Plant resistance and promotion plant nutrient absorb, and are remarkably improved chemical fertilizer utilization rate.

It is can be seen that from the result of above-mentioned table 2 compared with blank control group, pest and disease damage incidence is bright after Fertilizer application of the invention Aobvious reduction.Compared with blank control, although pest and disease damage incidence also has certain decline after comparative example 3-5 Fertilizer application, It is unobvious.This is relatively low mainly due to the bactericidal effect due to single microorganism strain, and after a variety of strain reasonable compatibilities, respectively Synergistic bacterium is acted on, and reaches a stable microorganism ecological environment, beneficial bacterium viable count is more, and bactericidal and bacteriostatic effect is also more aobvious Write, the resistance and nutrient absorption for adding plant are harmonious, thus effect is more obvious.
