Performance test
(1) soil permeability of compound manure improves test
Multiple adjacent block in same experimental plot are adopted to test, apply 25kg fertilizer according to every 100m2 to apply fertilizer, find that the time limit of using along with compound manure increases, soil can become loose, breathe freely, produce without caking phenomenon, the transparent performance of soil can be improved.
Wherein, the permeability situation of experimental plot soil after 3 years compound manure is used in table 1.
The permeability of table 1. water-loss reducer of soil improves test result
From the experimental result of table 1, the life-time service of compound manure of the present invention can increase the porosity of soil, and the ratio that wherein non-capillary pipe space accounts for general porosity effectively increases, thus significantly improves the permeability of soil.
Wherein, when not adding additive and do not add modified paligorskite powder (D1-D2), the ventilation property of soil has significant reduction, even very nearly the same with control group soil, this demonstrate that additive and modified paligorskite powder significantly can improve the permeability of soil.
Therefrom also can find out, when polygorskite is carried out modification, its to soil have improved breathability to be far superior to not carry out modification time (Data Comparison see DY-1 to DY-3 and D6), this demonstrate that when adopting method of modifying of the present invention to carry out modification to polygorskite, compared to unmodified, there is beyond thought remarkable improvement to the permeability of soil.
(2) on the impact of corn yield
Experimental design: field is divided into multiple block, then carries out different fertilizer and applies, and tests its impact on corn yield.
Process 1: be control group, applies the Chemical Mixed Fertilizer of preparation example 1.
Process 2: be experimental group, apply compound manure of the present invention;
Process 3: be comparative group, apply comparative example compound manure of the present invention.
Fertilising consumption: apply according to every mu of applying fertilizer 50kg.
Each block area is 50m2, eachly includes three blocks in process 1, process 2 and process 3, and experimental result gets the mean value of three pieces, is then converted to per mu yield output.
For testing kind: corn Zheng Dan 958.
Experimental technique: carry out according to known corn seeding, fertilising, weeding and harvesting method and season.
Experimental result sees the following form 2.
Table 2
Can be found out by the result of table 2, compound manure of the present invention can improve the utilization ratio of fertilizer, crop efficient absorption is utilized, thus reaches the object possessing crop yield, compare the comparative example compound manure being used alone Chemical Mixed Fertilizer or lacking component and there is more excellent effect.
Therefrom also can find out, when not adding additive, per mu yield has remarkable reduction (see D1); When not adding modified paligorskite powder, its per mu yield reduces the most obvious, even with only use the control group output of preparation example 1 Chemical Mixed Fertilizer (see D2) very nearly the same, this demonstrate that polygorskite powder is through of the present invention so modified, it can produce good soil permeability and fertilizer efficiency strengthens (see the step (2) of method of modifying, may be that nutriment in a fertilizer to be diffused in the passage of polygorskite then supervention and to have waved slow releasing function, contriver is for furtheing investigate further), the collaborative of these two aspects creates significantly improving of per mu yield; And when polygorskite powder carries out modification, its per mu yield has remarkable reduction equally.
In addition, also can find out, when lacking other components or changing, cause per mu yield decrease to some degree equally.
In sum, compound manure of the present invention has excellent effect of promoting production, and this depends on the collaborative promotion of wherein multiple component, especially the factor such as the use of the adding of additive, modified paligorskite powder and composite metal salt separately and/or component.
(3) while employing aforesaid method (2) research compound manure is on the impact of corn yield, have studied the preventive effect to Tanaka weeds after at every turn applying fertilizer, specifically observe the herbicidal effect of fertilising after 30 days, the Chemical Mixed Fertilizer wherein in " Chemical Mixed Fertilizer " of control group i.e. preparation example 1.Experimental result is in table 3.
The experimental result of table 3. dispenser after 30 days
From the experimental result of table 3, compound manure of the present invention effectively can suppress the growth of the various weeds in field, thus avoids fertilizer by weeds absorption, utilization, thus makes utilization rate of fertilizer higher, and soil can not be caused to lie waste the generation of phenomenon, enrich the functional of fertilizer.
Also can find out, when lacking component 2-vinylformic acid-(1S in auxiliary agent, 1 ' R)-2-[1-(3 ', 3 '-dimethyl-1 '-cyclohexyl) oxyethyl group] and-2-methyl propyl ester time, cause having the preventive effect of weeds significantly reducing, this demonstrate that this material can improve the anti-herbicidal performance of nicosulfuron significantly, there is beyond thought synergy.
In sum, compound manure of the present invention is by the experiment screening of constituent species, the optimization of preparation technology, achieve preparation and the function optimization of polyelement composite fertilizer, make it have concurrently and improve utilization rate of fertilizer, soil improvement and antibacterial herbicidal performance, synergy between component makes compound manure of the present invention have beyond thought multi-efficiency, has agricultural application very widely and is worth and market outlook.
Should be appreciated that the purposes of these embodiments is only not intended to for illustration of the present invention limit the scope of the invention.In addition; also should understand; after having read technology contents of the present invention, those skilled in the art can make various change, amendment and/or modification to the present invention, and these all equivalent form of values fall within the protection domain that the application's appended claims limits equally.
