Description
Technical field
The present invention relates to raising rice seedlings technical field, particularly relate to a kind of multifunctional paddy seedbed conditioner and preparation method thereof.
Background technology
Oryza sativa L. is equivalent to the mankind seedling and is in cradle period, and its nutritional characteristic and the requirement to environment such as soil have the particularity of four aspects: one is that rice plant grows imperfection, and various organ childrens are tender, and absorption function is low.Two is that health is small and weak, and environmental resistance is weak, it is easy to endangered by disease pest.Three is that environment reaction is sensitive, and soil ph, humidity, oxygen, temperature etc. are had very strict requirement.Four is have very special dietary demand, and the nutrient such as soil nitrogen phosphorus potassium and medium trace element, form and proportion requirement is very special.Must strictly meet his nutrition and environmental requirement, can be only achieved the purpose physically well developing, growing up healthy and sound.
The industry development of transplanting seedlings of current China industrial sprout cultivation, mechanization is in the ascendant.On market, seedbed conditioner mainly adopts normal soil to add organic fertilizer or calcium superphosphate.But these element ratios such as Nitrogen, Phosphorus potassium and zinc are unreasonable, and fertilizer efficiency is low, and soil miscellaneous bacteria is many, it is easy to infecting pest and disease damage, effect is undesirable.Seriously constrain industrial sprout cultivation, the development of industry is transplanted seedlings in mechanization, have impact on rice 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 multifunctional paddy seedbed conditioner and preparation method thereof.Solving existing common fertilising material, ratio is unreasonable, also to mend and execute other fertilizer, cause 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:
A kind of multifunctional paddy seedbed conditioner of the present invention, including N P and K a great number of elements, zinc microelement, regulating acid agent and antibacterial, wherein, the mass ratio of described a great number of elements and trace element is 1 0.021；The mass ratio of described a great number of elements nitrogen, phosphorus and potassium is 1 0.49 0.24；With described nursery bed special fertilizer material for benchmark, the weight/mass percentage composition of described regulating acid agent is 7.5%-8%, and the weight/mass percentage composition of described antibacterial is 1%-1.5%.
In the present invention, the consumption of nitrogen is in elemental nitrogen, and the consumption of phosphorus is with P2O5Meter, the consumption of potassium is with K2O counts, and the consumption of calcium is in element calcium, and the consumption of zinc is in element zinc.
Preferably, with described nursery bed special fertilizer material for benchmark, the weight/mass percentage composition of described regulating acid agent is 7.6%, and the weight/mass percentage composition of described antibacterial is 1.1%.
In the present invention, the interpolation of described nitrogen element is added with the salt compounds form containing nitrogen element, for instance, nitrate or ammonium salt.Preferably employ ammonium salt, specifically, such as ammonium nitrate.
In the present invention, the interpolation of described P elements is added with the salt compounds form containing P elements, for instance, phosphate or perphosphate etc..Preferably employ perphosphate.Specifically, such as calcium superphosphate.

In the present invention, the interpolation of described zinc element is added with the salt compounds form containing zinc element, for instance, zinc sulfate, zinc chloride or zinc phosphate etc..Preferably employ zinc sulfate.
Further, described regulating acid agent adopts organic acid.Preferably employ citric acid.Adopt organic acid regulating acid agent can provide slightly acidic environment at the whole trophophase of rice seedling better, be beneficial to the growth of rice seedling.
Preferably, described antibacterial adopts commercially available soil antibacterial., described antibacterial preferentially adopts the comprehensive antibacterial of soil.Adopting antibacterial can kill soil pest and disease damage, preventing and treating is sick for seedling stage.
Further, the granularity of described multifunctional paddy seedbed conditioner is not more than 4mm.It is preferably 0.5mm～4mm.
Further, the water content in the conditioner of described multifunctional paddy seedbed is less than 10% (wt.).Preferably, water content is controlled less than 5% (wt.).
The preparation method of currently preferred multifunctional paddy seedbed conditioner, comprises the following steps:
Step one, according to the component of multifunctional paddy seedbed conditioner and consumption, weigh nitrogen element, P elements, potassium element and zinc element and regulating acid agent, antibacterial；
Step 2, by nitrogen element, P elements, potassium element and zinc element, and regulating acid agent, antibacterial through pulverizer pulverize, obtain crushed material；
Step 3, crushed material step 2 obtained, through bolting, obtain fines；
Step 4, fines step 3 obtained mix through blender, obtain multifunctional paddy seedbed conditioner.
Further, in step 2, adopt 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, obtains fines.
A kind of multifunctional paddy seedbed provided by the invention conditioner, it is draw on the creationary basis analyzing contrast and field test, having very strong specific aim, as a kind of comprehensive fertilizer, it disposable can complete rice shoot fertilising, seedling bed regulating acid, three programs of soil disinfection.There are three large effects: first is provide the nutrient such as N P and K and trace element on request.The growth promoter of rice shoot, having specific N P and K and trace element demand, for making seedling growth vigorous, dry-matter accumulation is many, seedling quality is good, according to seeding stage regulation of fertilizer requirement, in line with suitably controlling nitrogenous fertilizer, phosphorus, potash fertilizer must be increased, join the principle of trace element ingeniously, scientifically assemble nutrient and applied once, the trace element such as a great number of elements zinc such as the nitrogen needed for the seedling growth phase, phosphorus, potassium can be substantially met.Second is regulate soil pH value, to subacidity state.Seedling growth happiness subacidity soil environment, when pH Value of Bed Soil is 4～5, rice shoot can play best physiological function.Regulating acid agent is puddled after nursery soil, runs into water and can quickly reduce bed soil pH value, and can keep the subacidity edaphic condition of suitable seedling growth the long period.3rd is nursery soil sterilization, prevents and treats seedling stage diseases and pests.Slightly acidic environment and antibacterial can reduce the generation of pest and disease damage well.By three large effects, cultivate Oryza sativa L. strong sprout, prosperous Seedling is early sent out, improve transplanting survival rate, rice shoot main manifestations short strong, leaf thickness, Ye Kuan, dark green, stem foot width, well developed root system, move that turn green after (throwings) plants (vertical Seedling) fast, tiller early, tiller is many, heading early, ripe morning, there is obvious effect of increasing production.
The preparation technology of the multifunctional paddy seedbed conditioner of the present invention is simple, pulverizes in order, sieves, mixes.By nitrogen element, P elements, potassium element and zinc element, and regulating acid agent, antibacterial are pulverized through pulverizer, by crushed material through bolting, are mixed through blender by fines, obtain multifunctional paddy seedbed conditioner, be more beneficial for the growth of rice seedling.
Detailed description of the invention
Below in conjunction with embodiments of the invention, technical scheme is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
