Rhizomadioscoreae is also referred to as Rhizoma Dioscoreae, has another name called Rhizoma Dioscoreae and long taro, belongs to Dioscoreaceae, and tuber or cylindric with its hypertrophy are edible.
Containing protein 1.5% in tuber, carbohydrate 14.4%, and containing multivitamin and choline etc., nutritive value is higher.
Rhizoma Dioscoreae is perennial root trailing plant, likes warm, can not resist cold, tuber start for more than 10 DEG C germinate, stem and leaf growth with 25 DEG C ~
28 DEG C is the suitableeest, and tuber expands with 20 DEG C～24 DEG C the fastest.Rhizomadioscoreae growth is extensive, medicine, dish dual-purpose, and the masses like plantation.Rhizomadioscoreae
Throughout the year for plant the crop gathered in the crops then then in cultivation, Rhizomadioscoreae can be eaten or be processed into dry tablet raw and make medical material, it is possible to further
Deep processing and utilization, its huge market demand.
Along with the development of modern agriculture, the application of fertilizer slow release technology is the most gradually popularized.But, existing slow release fertilizer profit
Low by rate, slow release effect is slow and limited, does not also have simultaneously and prepare specific delaying for specific crop varieties in currently available technology
The research report of release fertilizer, must so developing that a kind of Rhizomadioscoreae slow release fertilizer suiting Rhizomadioscoreae growth cycle and absorption characteristic extremely has
Want.
Summary of the invention
It is an object of the invention to: for the problem of above-mentioned existence, it is provided that a kind of Rhizomadioscoreae slow release fertilizer and preparation side thereof
Method.Rhizomadioscoreae slow release fertilizer of the present invention is prepared according to Rhizomadioscoreae growth cycle and absorption characteristic；Utilization rate is high, slow release effect moderate and
Stable, balanced in nutrition, can effectively reduce the turnover rate of fertilizer, improve the yield of Rhizomadioscoreae.
In order to realize the purpose of foregoing invention, the technical solution used in the present invention is as follows:
A kind of Rhizomadioscoreae slow release fertilizer, described slow release fertilizer is made up of coated fertilizer and fertiliser granulates；

Present invention also offers the preparation method of described Rhizomadioscoreae slow release fertilizer, described preparation method is:
1) raw material of fertiliser granulates being added suitable quantity of water mix homogeneously and put into granulator granulation, post-drying, to water content≤6%, obtains
It is the fertiliser granulates of 1.5-3.0mm to particle diameter；
2) weighing the raw material of coated fertilizer again, coated fertilizer solution is made in intensification polymerization；
3) use coated fertilizer solution to carry out the peplos of fertiliser granulates, be dried to water content≤6%, make Rhizomadioscoreae slow release fertilizer.
One of important molecule during sodium alginate oligosaccharide is oligosaccharide in lapping, is obtained by degraded sodium alginate
By а-L-mannuronic acid (mannuronic acid, M) and b-D-guluronic acid (guluronic acid, G) rely on Isosorbide-5-Nitrae-
Glycosidic bond connects and the oligosaccharide that is made up of different fragments (MM section, GG section and MG section), has that relative molecular mass is little, toxicity
The advantages such as low, absorbability is strong, have higher biological activity, have certain regulatory function to growth and development of plants；Polypropylene
Amide, lignin and Pulvis Talci are auxiliary coated fertilizer, and glacial acetic acid is secondary solvent, and Ammonium persulfate. is initiator.
The fertilizer that biological bacteria is made has the function of volume increase, improving quality, also substantially reduces nitrate in Rhizomadioscoreae body, sub-
Nitrate and content of beary metal, improve the effect such as chemical fertilizer utilization ratio and fertilizing soil.
Containing numerous nutritional labelings in waste residue, it is possible to provide the nutrition of Rhizomadioscoreae growth demand as fertilizer, promote Rhizomadioscoreae
Growth.
Humic acid energy improved soil nodule structure, chesson, improves the fertilizer-preserving ability of soil.
Lumbricus powder is the high-efficiency high-quality fertilizer that a kind of nitrogen, phosphorus, potassium content are complete, can not only improve soil using it as fertilizer
And can make that melon is more fragrant, fruit is sweeter, dish is fresher, Lumbricus powder contains rich in protein and mineral in addition, its breaks down proteins
The aminoacid become can promote root growth, strong sprout, healthy tree, the photosynthetic function of enhancing blade and crop degeneration-resistant.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
(1) lapping in the present invention be mainly composed of fat and sodium alginate oligosaccharide, wide material sources, cheap, suitable
In large-scale promotion.
(2) the fertilizer control release speed of the present invention is moderate and stablize, and fertiliser granulates is balanced in nutrition, can effectively reduce the stream of fertilizer
Mistake rate, improves the utilization ratio of fertilizer, promotes that Rhizomadioscoreae is quickly grown up healthy and sound, improves Rhizomadioscoreae yield.
(3) the Rhizomadioscoreae slow release fertilizer preparation method of the present invention is simple to operate, beneficially popularization and application.
