The invention relates to a soil root application compound fertilizer, in particular to a special soil root application compound fertilizer for tea rich in selenium and a preparation method and a fertilizing method thereof. The compound fertilizer comprises the following components by weight percent: 30%-40% of fermented chicken manure, 12%-20% of fermented soybean meat, 12%-20% of fermented rapeseed meal, 25%-40% of nitrogenous fertilizer, 3%-8% of ground phosphate rock, 5%-15% of potassium chloride, 0.1%-0.5% of boron, 0.1%-0.5% of selenium, and 0.1%-0.5% of zinc. By adopting the technical scheme, inorganic selenium and amino acid in the tea are combined so as to be converted into organic selenium, therefore, the tea not only grows vigorously and has strong resistivity but also has high yield.

Description

Selenium-rich tea leaf plantation special-purpose soil root sealing fertilizer and preparation method thereof and fertilizing method

Technical field

The present invention relates to a kind of soil root sealing fertilizer, relate in particular to a kind of selenium-rich tea leaf plantation special-purpose soil root sealing fertilizer and preparation method thereof and fertilizing method.

Background technology

Because selenium is the important component part of some antioxidases (Selenoperoxidase) and selenium-P albumen in animal and human's body, play a part in vivo balance oxidation reduction atmosphere, studies have shown that and there is the effect of the animal immunizing power of raising, selenium is the hot issue in this field for the research of immunizing power impact and cancer prevention in the world, therefore, selenium can be used as animal-feed trace mineral supplement, also in vegetable fertilizer, adds trace element fertilizer, improves agricultural byproducts selenium content.

According to sand smeller, investigate: the area of China 72% belongs to and lacks selenium area, and the natural food selenium contents such as grain are lower; The big and medium-sized cities such as North China, northeast, northwest all belong to and lack selenium area, the wide geographic area of Shi Erge provinces and cities of middle state-two, and approximately 700,000,000 people live in low scarce selenium area.Scientist measures: some disease, particularly tumour, hypertension, endocrine metabolism disease, diabetes, senile constipation are all relevant with scarce selenium.Selenium is 1/10000000th at tissue intensive amount, but it has determined the existence of life, to the great function of human health, is that other materials are irreplaceable.Scarce selenium can directly cause human immunological competence to decline, clinical medicine proves, threaten 40 various diseases of human health and life all relevant with the scarce selenium of human body, as cancer, cardiovascular diseases, hepatopathy, cataract, pancreas disease, diabetes, reproductive system disease etc.According to expert's textual criticism, people needs to mend throughout one's life selenium.No matter be experimentation on animals or clinical practice, all illustrated and constantly from diet, obtain the selenium of q.s, can not supplement in time, will reduce the ability of getting rid of illness.Therefore, mending selenium has become a kind of trend that we pursue health, is also imperative healthy mission.

Original tea is grown in hill in one's early years, and cloud and mist curls up throughout the year, and tea leaf quality is high, and mouthfeel is good, and the tealeaves of low height above sea level plantation is difficult to have mouthfeel and the sweet-smelling of wild tealeaves.Except kind factor, there is relation with humus in soil and micronutrient levels, particularly the content of selenium element wherein.Boron, selenium, zinc are to tea growth and improve the yield and quality all very favourablely, and are of value to HUMAN HEALTH.

Chinese invention patent application (application number: 200910159719.9 applyings date: 2009-07-09) disclose selenium tea special-purpose soil root fertilizer formula material weight percent: nitrogen (∑ N)=14%; Phosphorus=4%; Potassium (K2O)=7%, organic=15% (biological bacteria of organic fermentation adopts ferment mushroom), zinc (Zn)+boron (B)+manganese (Mn)+molybdenum (Mo)+selenium (se)=5 ‰, all the other are siliceous (Si), the materials such as calcium (Ca) are stopping composition.

Chinese invention patent application (application number: 201210047845.7 applyings date: 2012-02-23) disclose a kind of rich selenium special bio compoiste fertilizer of producing functional type agricultural-food, this product be take mycelium and is mixed span amino acid mother liquor, humic acid, animal dung, probiotic bacterium, containing selenium, zn cpds, is main raw material, coordinate nitrogen, phosphorus, potassium etc. to coordinate raw material, high-intensity water absorbent agent, crop material, stevia rebaudiana dregs etc., be uniformly mixed in bio-reactor, fully after fermentation dehydration, make water content be controlled at 14% left and right, then be crushed to 50～75 order granulations.

Summary of the invention

In order to solve the tealeaves of low height above sea level plantation, be difficult to have the mouthfeel of wild tealeaves and the technical problem of sweet-smelling, an object of the present invention is to provide a kind of selenium-rich tea leaf plantation special-purpose soil root sealing fertilizer, adopt after this composite fertilizer tealeaves not only grow vigorous, resistivity is strong, and output is high.Tealeaves is after processing, and color, smell and taste are all good, not only adopts in the mouthfeel of remote mountains wild tea equally with former, and has reduced the bitter taste of wild tea tree, and can extend the quality guaranteed period of tealeaves.Another object of the present invention is to provide the preparation method of above-mentioned selenium-rich tea leaf plantation special-purpose soil root sealing fertilizer.The 3rd object of the present invention is to provide the fertilizing method of above-mentioned selenium-rich tea leaf plantation special-purpose soil root sealing fertilizer.

Embodiment

Below the embodiment of invention is described further.

The method of selenium-rich tea leaf plantation special-purpose soil root sealing fertilizer, the method comprises the following steps:

1) by tin anhydride for 0.15KG water dissolution, zinc sulfate for 0.26KG water dissolution, borax 0.2KG in 65 ℃ of hot water, dissolve, element is stirred, do mixed aqueous solution, place after 3 hours and to use;

2) nitrogenous fertilizer 36KG, ground phosphate rock (phosphorus content 30%) 8KG, Repone K 10KG tri-things are mixed to stirring;

3) the chicken manure 34KG having fermented, dregs of beans 15KG dish dregs of rice 15KG are mixed, drive powdered away, mixed aqueous solution in sprinkling;

4) on the basis of step 3), add step 2) mixture made, stir, make coarse particles shape, be distributed into every bag of 25KG, envelope is deposited.

In the process of fermentation poultry dung, dregs of beans, the dish dregs of rice, should look Various Seasonal and weather condition and grasp the temperature of controlling its fermentation.In its specific operation process, leavening temperature is being controlled to 45 ℃ ± 5 ℃, fermented product should cover one deck nylon film.Every other day measure leavening temperature, as too high, raise film, spread cooling out, and spill appropriate water.Too low when temperature, can spray appropriate hot water, fermentation time is controlled at 15-20 days.

During fertilising, should note the pH value in soil, when discharge this fertilizer in acid soil, should first discharge the plant ash of equivalent weight, and then discharge tea rich in selenium Wei Yong composite fertilizer, to regulate the pH value in soil, because selenium fermentation is in neutral or weakly alkaline soil and absorbed by tea tree, otherwise be just difficult to be absorbed by tea tree, reduced the effect of fertilizer.
