Do not change, belong to perennial herbaceous stem fallen leaves liana, up to several meters, without hair, root tuber is very large, oblate spheroid, flower unisexuality for complete stool, different strain；Flower
Sequence axillary, flat-top shape umbel is formed by a small number of cymule set, spends tiny mulberry, has white powder, 5~June of florescence；
Drupe is circular, red, the seed ring-type by green, white, 8~September of fruiting period.Stephania epigaea happiness be born between Limestone Region, bamboo or twig fence or
In many stone hills and bramblebush clump, tor is often born in, also common cultivation.Originate in Eastern Yunnan, middle part and western part, western Sichuan
And south, the Guangxi northwestward to the west and south.Nature and flavor：Bitter, acrid, cold, it is poisonous.With clearing heat and detoxicating, dampness removing, analgesic efficacy.For
Stomachache, stomachache, acute gastroenteritis, rheumatic arthritis, malaria；Carbuncle furuncle poison, eczema are controlled in external application.Herb containing alkaloid 0.4~
0.7%, root tuber contains alkaloid 2.2%, is delavaine and 16- oxygen delavaines.
Due to Stephania epigaea happiness be born between Limestone Region, bamboo or twig fence or many stone hills and bramblebush clump in, the nutrition in soil
Composition is less, mainly by natural growth, causes slow-growing, and product yield and quality be not high.Plantation Stephania epigaea fertilising at present
When, majority is using the common inorganic fertilizer such as organic fertilizer or urea such as animal wastes, and nutritional ingredient is single.Because Stephania epigaea grows week
Phase is long, and common utilization rate of fertilizer is low, causes the demand of fertilizer to increase, and increased the cost of plantation.
The content of the invention
In order to solve the above problems, the invention provides a kind of Stephania epigaea Special slow release fertilizer and preparation method thereof.The present invention
Stephania epigaea slow-release fertilizer have comprehensive nutrition, had good sustained release effect, utilization rate high, low cost prepares simple, not generation environment pollution
The advantages of, the yield of Stephania epigaea can be significantly improved, alkaloid is improved, the cost of plantation Stephania epigaea is reduced, significantly carry
The income of peasant high, with good economic benefit, can very well promote the large-scale production of Stephania epigaea.
The present invention is achieved through the following technical solutions：
A kind of Stephania epigaea Special slow release fertilizer, including following parts by weight raw material：50~80 parts of urea, 40~50 parts of potassium phosphate,
30~45 parts of potassium dihydrogen phosphate, 5~15 parts of magnesium sulfate, 2~3 parts of zinc sulfate, 4~6 parts of sodium selenite, 3~5 parts of borax, molybdic acid
1~2 part of ammonium, 4~7 parts of calcium superphosphate, 10~15 parts of tea bran, 20~30 parts of bagasse, 10~20 parts of expanded vermiculite, coating agent 15~
20 parts, 0.1~0.5 part of plant growth regulator.
Preferably, the raw material of the above Stephania epigaea Special slow release fertilizer, including following parts by weight：60 parts of urea, phosphoric acid
45 parts of potassium, 35 parts of potassium dihydrogen phosphate, 10 parts of magnesium sulfate, 3 parts of zinc sulfate, 5 parts of sodium selenite, 4 parts of borax, excessively 2 parts of ammonium molybdate, phosphorus
5 parts of sour calcium, 13 parts of tea bran, 25 parts of bagasse, 16 parts of expanded vermiculite, 18 parts of coating agent, 0.4 part of plant growth regulator.
Preferably, the above coating agent is montmorillonite and starch.
Preferably, the proportioning of the above montmorillonite and starch is 12~14: 1~8.
Preferably, the above plant growth regulator is one or two in compound sodium nitrophenolate, amine fresh fat arbitrarily comparing
Example mixing.
Preferably, the particle diameter of the above expanded vermiculite was 80~100 mesh sieves.
The present invention also provides a kind of preparation method of Stephania epigaea Special slow release fertilizer, comprises the following steps：
（1）Tea bran, bagasse are crushed respectively, 60~80 mesh sieves are crossed, mixed fermentation is ripe, obtains tea bran powder and bagasse powder；
（2）Plant growth regulator is dissolved in 10~20 times of weight waters, Plant growth regulator water solution is made, then will be swollen
Swollen vermiculite is immersed in 5~8h in Plant growth regulator water solution, obtains immersion material；
（3）By urea, potassium phosphate, potassium dihydrogen phosphate, magnesium sulfate, zinc sulfate, sodium selenite, borax, ammonium molybdate, calcium superphosphate,
The each components such as tea bran powder, bagasse powder, immersion material are well mixed, and obtain compound, are put into comminutor；

2nd, Application Example
In Hechi City, Guangxi all An Countys, in March, 2010 on the tor of In Limestone Area, 210 plants of plantation Stephania epigaea planting stock,
210 plants of seedlings averagely separate 7 groups, respectively every group 30 plants, experimental group one, experimental group two, experimental group three, experimental group four, reality
Test group five, control group one, control group two.Wherein one~experimental group of experimental group five corresponds to apply 1~embodiment of embodiment 5 respectively
Stephania epigaea special fertilizer, control group one applies the human and animal excreta of moisture content 35~40%, and control group two applies 50% urea, 50% N P and K
Composite fertilizer.Time of application is：Respectively applied fertilizer once with annual March, October in plantation, each every plant of 100g.In in November, 2013
Harvest within 15th, measure the diameter of Stephania epigaea root tuber, average, appoint for every group and take 3 Stephania epigaea root tubers, be to tetrahydropalmatine
Reference substance, root tuber total alkaloid content is measured using acid-dye colorimetry, is averaged, each parametric measurement value such as following table of gained
1。
The Stephania epigaea of table 1 harvests parametric measurement value
| Root tuber average diameter（cm） | Root tuber total alkaloid content（%） | |
| Experimental group one | 18.2 | 7.97 |
| Experimental group two | 17.9 | 7.89 |
| Experimental group three | 18.9 | 8.13 |
| Experimental group four | 18.7 | 8.10 |
| Experimental group five | 18.6 | 8.09 |
| Control group one | 15.3 | 7.61 |
