Abstract
The invention relates to the technical field of orchid plantation fertilizers, and especially relates to a preparation method of a controlled release fertilizer used for orchid plantation. The method comprises the following steps: reasonably proportioning polyurethane, polyvinyl alcohol, starch, glycerin and an aqueous solution of potassium alginate, adding gypsum power to prepare a coated slurry, granulating and drying the fertilizer, and wrapping the granulated and dried fertilizer. The prepared controlled release fertilizer has the advantages of long slow release cycle, uniform nutrient release rate, effective maintenance of nutrient demands of orchid growth, easiness in degradation of a coating layer, realization of degradation of the coating layer by soil with the release of the nutrients in the long-term low release process, improvement of the soil structure of an orchid plantation matrix or an orchid plantation, and increase of the survival rate of orchid.
Description
Technical field
The present invention relates to Orchis planting uses fertilizer technology field, especially a kind of Orchis planting Controlled Release Fertilizer preparation method.
Background technology
With the continuous improvement of people's living standard, substantial amounts of people is in room, plant flowers and plants on balcony, in garden, beautiful
Change living environment.So that flowers and plants can more preferably grow up strong and sturdy faster, in flowers and plants planting process, need flowers and plants are carried out
Fertilizer treatment, improves the growth quality of flowers and plants；In order to meet consumer demand, substantial amounts of researcher is had to plant for flowers and plants
Fertilizer in journey is studied so that flowers and plants growth is vigorous, and such as number of patent application is 201410663044.2 special fertilizer for orchid,
Using carbamide, sheep stool, corn cob, manganese sulfate, sub- uncommon acid sodium composition, enabling for, in Cymbidium ensifolium (L.) Sw. growth course, providing abundant
Nutrient；But, in flowers and plants planting process, it needs to apply thin fertile it is not necessary to apply dense fertilizer mostly, especially Cymbidium ensifolium (L.) Sw., and it is being planted
During plant, requirement to dose more strict it is therefore desirable to constantly carry out fertilizer treatment to Cymbidium ensifolium (L.) Sw. so that Orchis planting
Labor intensity larger；After in the soil and fertilizer of the prior art applies fertilizer, it easily causes soil compaction, and then affects
Cymbidium ensifolium (L.) Sw. grows, or even promotes Cymbidium ensifolium (L.) Sw. dead.
Content of the invention
In order to solve above-mentioned technical problem present in prior art, the present invention provides a kind of Orchis planting Controlled Release Fertilizer system
Preparation Method.
It is achieved particular by technical scheme below：
A kind of Orchis planting Controlled Release Fertilizer preparation method, comprises the following steps：
(1) fertilizer is placed in pelletize in comminutor, and dries preparation dry particle；
(2) by polyurethane, polyvinyl alcohol, starch, glycerol, potassium alginate aqueous solution according to mass ratio be 0.1:0.2-0.4:
3-6:1-3:After 10-20 mixing, being placed in temperature is 50-70 DEG C of hyperthermic treatment 10-20min, obtains mixed liquor；
(3) add, in mixed liquor, the Gypsum Fibrosum powder accounting for mixed liquor quality 3-9%, stir, obtain peplos slurry；By drying
Granule is placed in seed-coating machine, and sprays into peplos slurry thereto, sprays into peplos slurry and accounts for dry particle quality 4-8%, adjusts moisture content
For 5-11%, you can.
Described fertilizer, it is added to account for the potassium citrate of fertilizer quality 1-3% in granulation process.
Described potassium alginate aqueous solution, its mass concentration is 1-5%.
Described Gypsum Fibrosum powder, its fineness is 600-1000 mesh.
Described fertilizer, its material composition is WUDUOYUN powder 1-3 part, Herba Artemisiae Annuae 0.1-0.5 part, white vinegar 1- in parts by weight
3 parts, potassium dihydrogen phosphate 3-7 part, carbamide 5-8 part, fertile soil 8-10 part, plant ash 2-4 part.
Described fertilizer, its material composition is 2 parts of WUDUOYUN powder, 0.3 part of Herba Artemisiae Annuae, 2 parts of white vinegar, phosphoric acid in parts by weight
5 parts of potassium dihydrogen, 7 parts of carbamide, 9 parts of fertile soil, 3 parts of plant ash.
Compared with prior art, the technique effect of the present invention is embodied in：
By using polyurethane, polyvinyl alcohol, starch, glycerol, potassium alginate aqueous solution rational proportion, and add Gypsum Fibrosum powder
Prepare peplos slurry, after granulation of fertilizer is dried, parcel so that the slow release cycle of the Controlled Release Fertilizer of preparation is longer, the nutrient of release
Rate uniform, can effectively maintain the nutrient demand of Cymbidium ensifolium (L.) Sw. growth, and coating layer is easy to degrade, can be in long-term slow release mistake
Cheng Zhong, with the release of nutrient, is utilized by soil degrading, improves the soil knot in Orchis planting substrate or Orchis planting garden
Structure, improves Cymbidium ensifolium (L.) Sw. survival rate.
This researcher puts into release through the slow-release fertilizer of embodiment 1-5 preparation is carried out pure water, and detects in pure water and always support
Divide situation of change, its result is as shown in table 1：

In addition, the potassium alginate aqueous solution composition in the invention, in Cymbidium ensifolium (L.) Sw. growth course, can be to Cymbidium ensifolium (L.) Sw.
Growth substrate, soil are had an effect so that the harmful components in soil are degraded, and improve Cymbidium ensifolium (L.) Sw. growing environment quality, improve
Survival rate；Add potassium citrate especially in fertilizer so that the potassium element in potassium citrate supplements potassium nutrition for Cymbidium ensifolium (L.) Sw., but also
Enable to citric acid by unnecessary calcium in Cymbidium ensifolium (L.) Sw. growing environment, magnesium component complexation so that potassium alginate composition occurs degraded profit
With, the Soil structure improving Orchis planting substrate or improving Orchis planting garden, and avoid peplos not degradable to environment
Bring impact, improve utilization rate of fertilizer, meet nutrient demand in Cymbidium ensifolium (L.) Sw. growth course, can be uniformly Cymbidium ensifolium (L.) Sw. for a long time
Nutrient is provided, meets the thin fertile fertilising of Orchis planting process, reduce Orchis planting labor intensity.
Fertilizer in the invention can also be using the Cymbidium ensifolium (L.) Sw. fertilizer of other formula preparation, 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
The formula of bright creation is so that fertilizer component, during release, to coating layer material effects, and then can promote it to drop
Solution, improves nutritional labeling, and can kill pathogenic bacteria, improves Cymbidium ensifolium (L.) Sw. survival rate, improves Cymbidium ensifolium (L.) Sw. growth quality.
