Description
Technical field
The present invention relates to botanical seedling culturing special fertilizer technical field, particularly relate to a kind of multi-functional nursery bed special fertilizer material
And preparation method thereof.
Background technology
Plant is equivalent to the mankind seedling and is in cradle period, its nutritional characteristic and to rings such as soil
The requirement in border has the particularity of four aspects: one is plant development imperfection, and various organ childrens are tender, absorbs merit
Can be low.Two is that health is small and weak, and environmental resistance is weak, is easily endangered by disease pest.Three is quick to environment reaction
Sense, has very strict requirement to soil ph, humidity, oxygen, temperature etc..Four be have the most special
Different nutritional need, to soil nitrogen phosphorus potassium a great number of elements and in nutrient, form and the ratio such as trace element
It is the most special to require.Must strictly meet his nutrition and environmental requirement, can be only achieved physically well develop, healthy become
Long purpose.
China's industrial sprout cultivation, nursery industry develop in the ascendant at present.On market, nursery fertilizer is mainly adopted
Organic fertilizer, or calcium superphosphate is added with normal soil.But these units such as Nitrogen, Phosphorus potassium and calcium zinc
Element ratio is unreasonable, and fertilizer efficiency is low, and soil miscellaneous bacteria is many, easily infects pest and disease damage, and effect is undesirable.Seriously
Constrain the development of industrial sprout cultivation, nursery industry, have impact on crop yield.
Summary of the invention
For drawbacks described above and the problem of prior art, it is an object of the invention to provide a kind of multi-functional seedbed special
With fertilizer and preparation method thereof.Solving existing common fertilising material, ratio is unreasonable, also to mend and execute other fertilizer
Material, causes the wasting of resources, the technical problem that fertilizer efficiency is undesirable.
In order to achieve the above object, the present invention provides following technical scheme:

Thing form is added, such as, and zinc sulfate or zinc chloride etc..Preferably employ zinc sulphate heptahydrate or a water sulfur
Acid zinc.
Further, described regulating acid agent uses organic acid.Preferably employ citric acid.Use organic acid regulating acid agent
Can preferably plant seedlings whole trophophase provide slightly acidic environment, beneficially plant seedlings growth.
Further, described antibacterial uses commercially available soil antibacterial.Antibacterial is used to kill
Soil pest and disease damage, preventing and treating is sick for seedling stage.
Further, the granularity of described multi-functional nursery bed special fertilizer material is not more than 4mm.It is preferably 0.5～4mm.
Further, the water content in described multi-functional nursery bed special fertilizer material is less than 10% (wt.).Preferably control
Water content processed is less than 5% (wt.).
The preparation method of currently preferred multi-functional nursery bed special fertilizer material, comprises the following steps:
Step one, according to the component of multi-functional nursery bed special fertilizer material and consumption, weigh nitrogen element, P elements,
Potassium element, calcium constituent and zinc element, and regulating acid agent and antibacterial；
Step 2, by nitrogen element, P elements, potassium element, calcium constituent and zinc element, and regulating acid agent, kill
Microbial inoculum is pulverized through pulverizer, obtains crushed material；
Step 3, crushed material step 2 obtained sieve through mechanical picker, obtain fines；
Step 4, fines step 3 obtained, through blender mix homogeneously, obtain multi-functional plant seedbed
Dedicated fertilizer.
Further, in step 2, use abrading type disintegrator to pulverize, become crushed material.
Further, in step 3, crushed material is not more than through mesh diameter the bolting of 4 millimeters,
Obtain fines.
The one multi-functional nursery bed special fertilizer material that the present invention provides, is through creative analysis contrast and field
Between draw that there is the strongest specific aim on the basis of test, as a kind of comprehensive fertilizer, it can be once
Property completes seedling fertilization, seedling bed regulating acid, three programs of soil disinfection.There are three large effects: first is on request
There is provided N P and K and in the nutrient such as trace element.The growth promoter of plant seedlings, has specific nitrogen
Phosphorus potassium and middle trace element demand, for making growth of seedling vigorous, dry-matter accumulation is many, and Seedling Quality is good, must
Must be according to Seedling Stage regulation of fertilizer requirement, in line with suitably controlling nitrogenous fertilizer, increase phosphorus, potash fertilizer, join middle trace element ingeniously
Principle, scientifically assemble nutrient, and applied once, can substantially meet the nitrogen needed for seedling growth stage,
The a great number of elements such as phosphorus, potassium and the multiple middle trace element such as zinc, calcium.Second is regulation soil pH value, to micro-acid
Sexual state.Growth of seedling happiness subacidity soil environment, when pH Value of Bed Soil is 4.0～6.0, seedling can send out
Wave best physiological function.Regulating acid agent is puddled after nursery soil, runs into water and can quickly reduce bed soil pH value,
And the subacidity edaphic condition of suitable growth of seedling can be kept the long period.3rd is nursery soil sterilization, anti-
Control seedling stage diseases and pests.Slightly acidic environment and antibacterial can the generations of prevention and elimination of disease and pests well.Pass through
Three large effects, cultivate plant strong sprout, and prosperous Seedling is early sent out, and carries and a few days ago transplanting, and improve transplanting survival rate, less
Pest and disease damage, seedling mainly shows short strong, leaf thickness, Ye Kuan, dark green, stem foot width, well developed root system, shifting (throwing)
Vertical Seedling of turning green after cultivation is fast, take root tiller early, tiller branch is many, bolting jointing early, yield positive results early, ripe
Early, there is obvious effect of increasing production.
The preparation technology of the multi-functional nursery bed special fertilizer material of the present invention is simple, mixes in order.In preparation
During, by nitrogen element, P elements, potassium element, calcium constituent and zinc element, and regulating acid agent and antibacterial
Pulverize, sieve, mix, obtain multi-functional nursery bed special fertilizer material, each former in this multi-functional nursery bed special fertilizer material
Evenly, mutual synergism is more preferable, is more beneficial for the growth of crop seedling in material mixing.
