Description
Technical field
The present invention relates to Orchis planting fertilizer technology field, especially a kind of Orchis planting Controlled Release Fertilizer preparation method.
Background technique
With the continuous improvement of people's living standards, a large amount of people in the room, on balcony, flowers and plants are planted in garden, beauty
Change living environment.In order to enable flowers and plants can more preferably grow up strong and sturdy faster, in flowers and plants planting process, need to carry out flowers and plants
Fertilizer treatment improves the growth quality of flowers and plants；In order to meet consumer demand, there is a large amount of researcher to plant for flowers and plants
Fertilizer in journey is studied so that flowers and plants growth it is vigorous, as number of patent application be 201410663044.2 special fertilizer for orchid,
Using urea, sheep dung, corncob, manganese sulfate, sub- uncommon sour sodium composition, make it possible to provide abundant in orchid growth course
Nutrient；But in flowers and plants planting process, need to apply thin fertilizer mostly, does not need to apply dense fertilizer, especially orchid, plant
During plant, the requirement to dose is more stringent, it is therefore desirable to constantly fertilizer treatment is carried out to orchid, so that Orchis planting
Labor intensity it is larger；And after fertilizer in the prior art applies fertilizer in soil, it is be easy to cause soil hardening, and then influence
Orchid growth, or even promote orchid dead.
Summary of the invention
In order to solve the above technical problems existing in the prior art, the present invention provides a kind of Orchis planting Controlled Release Fertilizer system
Preparation Method.
It is achieved particular by following technical scheme:
A kind of Orchis planting Controlled Release Fertilizer preparation method, comprising the following steps:
(1) fertilizer is placed in pelletizer and is granulated, and dry preparation dry particle；
(2) it is 0.1:0.2-0.4 according to mass ratio by polyurethane, polyvinyl alcohol, starch, glycerol, potassium alginate aqueous solution:
After 3-6:1-3:10-20 mixing, being placed in temperature is 50-70 DEG C of heating treatment 10-20min, obtains mixed liquor；
(3) land plaster for accounting for mixed liquor quality 3-9% is added into mixed liquor, stirs evenly, obtains coating slurry；It will dry
Particle is placed in seed-coating machine, and sprays into coating slurry thereto, is sprayed into coating slurry and is accounted for dry particle quality 4-8%, adjusts moisture content
For 5-11%.
The fertilizer, in granulation process, thereto added with the potassium citrate for accounting for fertilizer quality 1-3%.
The potassium alginate aqueous solution, mass concentration 1-5%.
The land plaster, fineness are 600-1000 mesh.
The fertilizer, material composition are 1-3 parts of five clouds powder, 0.1-0.5 parts of sweet wormwood, light-coloured vinegar 1- in parts by weight
3 parts, 3-7 parts of potassium dihydrogen phosphate, 5-8 parts of urea, 8-10 parts of fertile soil, 2-4 parts of plant ash.
The fertilizer, material composition are 2 parts of five clouds powder, 0.3 part of sweet wormwood, 2 parts of light-coloured vinegar, phosphoric acid in parts by weight
5 parts of potassium dihydrogen, 7 parts of urea, 9 parts of fertile soil, 3 parts of plant ash.
Compared with prior art, technical effect of the invention is embodied in:
By using polyurethane, polyvinyl alcohol, starch, glycerol, potassium alginate aqueous solution rational proportion, and land plaster is added
Coating slurry is prepared, after granulation of fertilizer drying, package, so that the sustained release period of the Controlled Release Fertilizer of preparation is longer, the nutrient of release
Rate uniform, the nutrient demand that can effectively maintain orchid to grow, and coating layer is easy to degrade, and it can be in long-term sustained release
Cheng Zhong is utilized with the release of nutrient by soil degrading, improves the soil knot in Orchis planting matrix or Orchis planting garden
Structure improves orchid survival rate.
This researcher passes through the slow-release fertilizer for preparing embodiment 1-5 and carries out pure water investment release, and detects in pure water and always support
Divide situation of change, the results are shown in Table 1:

In addition to this, the potassium alginate aqueous solution ingredient in the invention can be to orchid in orchid growth course
Growth substrate, soil are had an effect, so that the harmful components in soil are degraded, are improved orchid growing environment quality, are improved
Survival rate；Potassium citrate is especially added in fertilizer, so that the potassium element in potassium citrate is orchid supplement potassium nutrition, but also
Enable to citric acid that calcium extra in orchid growing environment, magnesium component are complexed, so that degradation benefit occurs for potassium alginate ingredient
With improving Orchis planting matrix or improve the soil texture in Orchis planting garden, and avoid coating not degradable to environment
It affects, improves utilization rate of fertilizer, meet nutrient demand in orchid growth course, can for a long time uniformly be orchid
Nutrient is provided, meets the thin fertilizer fertilising of Orchis planting process, reduces Orchis planting labor intensity.
Fertilizer in the invention can also be using the orchid fertilizer of other formula preparations, such as according to the patent No.
The formula of the poly micro element special fertilizer for orchid of 201410252186.X is prepared, but combines above-mentioned coated fertilizer, it is preferred to use this hair
The formula of bright creation, so that fertilizer component is during release, it can be to coating layer material effects, and then it is promoted to drop
Solution improves nutritional ingredient, and can kill germ, improves orchid survival rate, improves orchid growth quality.
