The micro organism composite fertilizer compositions of invention.
The application effect detection of the hydrophilic peplos auxiliary agent of microorganism activator:
(1) embodiment 1-6 group composite fertilizer compositions mensuration of disintegration in water
Use disintegration tester that embodiment 1-6 group composite fertilizer compositions carries out the mensuration of disintegration, measurement result
It is shown in Table 1.
Table 1 composite fertilizer compositions mensuration of disintegration in water
Obtained by above experimental result: peplos agent is not added with compound fertilizer's combination of ratio phosphate ester starch of the present invention
Thing extends 28.5% than the disintegration of the composite fertilizer compositions that with the addition of phosphate ester starch.This explanation is at bag
After adding the disintegrating agent of ratio of the present invention in film auxiliary agent, composite fertilizer compositions disintegration rate in water improves, battalion
The decomposition rate supporting material is accelerated, and can provide sufficient nutrition in time when the plant growth initial stage.
(2) embodiment 1-6 group Soil Microorganism indices measures and soil compaction situation statistical experiment
The useful number of viable of soil is added up: takes 3 mu of Chinese cabbage fields, is divided into 5 parts, 0.6 mu every part.
Again every part of field being equally divided into 6 groups, be set to embodiment 1-6 group field, often group 0.1 mu, takes respectively
The composite fertilizer compositions of amount embodiment 1-6 group, uniformly imposes on crop root.After one week, take upper soll layer 5～
Soil sample 5g at 10cm, carries out soil useful viable count statistical experiment.It is repeated 5 times above-mentioned experiment, draws
The results are shown in Table 2.
Effectively viable bacteria dispersion diameter measures: after applying fertilizer 1 week, measure effective viable bacteria dispersion range, effectively to live
Bacterium circle of dispersion average diameter represents, is repeated 5 times experiment, obtains a result and be shown in Table 2.
Soil compaction situation is added up: after applying fertilizer 1 month, observe each group of soil compaction situation, soil compaction feelings
Condition is divided into without hardening by soil compaction degree, harden and seriously harden, shown in result table 2.
The mensuration of table 2 Soil Microorganism index
Can be obtained by above experimental result: in embodiment 5 groups, in soil, living bacteria count amount is relatively low, has simultaneously
Effect viable bacteria distribution is little, and the composite fertilizer compositions in peplos auxiliary agent without precipitated calcium carbonate is used in this explanation,
It is unfavorable for increase and the dispersion of effective viable bacteria of soil living bacteria count amount；In embodiment 6 groups, due to compound
Without glycerol in the peplos agent of fertilizer composition, the useful number of viable of soil causing this group field is relatively low.Thus
Visible, peplos auxiliary agent adds the strain protective agent of ratio of the present invention and compound fertilizer's group of hydrophilic substance simultaneously
Compound can make living bacteria count amount in soil increase.
Being known by table 2, hardening do not occur in 1,2,3,4 groups of soil of embodiment, and embodiment 5 groups and enforcement
Seriously hardening occur in 6 groups of soil of example.The water-retaining property material in peplos agent without ratio of the present invention is used in this explanation
The composite fertilizer compositions of precipitated calcium carbonate, is easily caused soil and occurs hardening；Water is used to replace glycerol as bag
The composition of membrane, is also easily caused soil and occurs hardening.Therefore, peplos auxiliary agent adds water-retaining property material
Soil compaction can be effectively alleviated with the composite fertilizer compositions of hydrophilic substance.
(3) the every growth indexes of embodiment 1-6 group crop measures
In after sowing one week, uniformly impose on crop root with composite fertilizer compositions.After one month, the most each
Group Chinese Cabbage Yield and the height of disease-resistant rate, the results are shown in Table 3.
The every growth indexes of table 3 crop measures
Illustrated by data above, use yeast leaching powder and the precipitated calcium carbonate not containing ratio of the present invention in peplos agent
Composite fertilizer compositions, make the Chinese cabbage underproduction 13.4%, resistance against diseases reduce by 16.1%；It addition, use bag
In membrane, the anhydrous glycerol composite fertilizer compositions without ratio of the present invention makes the Chinese cabbage underproduction about 6.9%, disease-resistant energy
Power reduces by 6.2%.Therefore, use in peplos auxiliary agent add the organic matter of ratio of the present invention, strain protective agent and
The micro organism composite fertilizer of anhydrous glycerol, it is possible to reach to increase production, improve the effect of disease-resistant rate.
The announcement of book and teaching according to the above description, those skilled in the art in the invention can also be to above-mentioned
Embodiment changes and revises.Therefore, the invention is not limited in concrete reality disclosed and described above
Execute mode, some modifications and changes of invention be should also be as falling into the scope of the claims of the present invention
In.Although additionally, employ some specific terms in this specification, but these terms are intended merely to conveniently
Illustrate, the present invention is not constituted any restriction.
