Description
Technical field
The present invention relates to agricultural technology field, particularly a kind of selenium-enriched organic fertilizer and preparation method thereof.
Background technology
Selenium is the trace element that human body is indispensable, and is a kind of very capable antioxidant, it is possible to effective removing cancerigenic factor free radical, has the good reputation of " anticancer king ".Scientist finds after having investigated the relation between 20 national cancer mortalities and everyone selenium intake, the intake of selenium is few, cancer morbidity and mortality rate just increase, wherein especially obvious with the pulmonary carcinoma of colon cancer, cancer of pancreas, ovarian cancer, carcinoma of prostate and male and skin carcinoma etc..According to statistics, the whole world has 42 countries and regions to lack selenium；The investigation that Chinese Soclety of Nutrition does shows, China has area about 700,000,000 population of 2/3rds to be in scarce selenium state.Chinese Soclety of Nutrition recommends selenium intake every day to be per capita 50 ~ 200 micrograms, but now the day selenium intake of China adult only has 26 ~ 32 micrograms, and the bad situation of selemium nutrition is at China's ubiquity.
Squama Manis and Gecko are all wild animal medical materials, and for a long time, owing to demand is continuously increased, and yield constantly reduces, and the phenomenon that supply falls short of demand occur.Guangxi is the main place of production of Squama Manis and Gecko, the geographical environment in Guangxi, weather is all suitable for the ectogenesis of Squama Manis and Gecko, current artificial cultivation Gecko and Squama Manis all succeed, for improving the resistance against diseases of Gecko and Squama Manis, in the process of artificial cultivation, poultry raiser can add the feedstuff containing selenium or food, the feces that Gecko and Squama Manis are discharged also can contain the selenium of trace, if can by the feces of Gecko and Squama Manis further with, make selenium-enriched organic fertilizer, it is beneficial to form Mode of Circular, reduce the aquaculture cost of cultivation Gecko and Squama Manis simultaneously.
Summary of the invention
The invention provides a kind of selenium-enriched organic fertilizer and preparation method thereof, the feces of Gecko and Squama Manis is recycled, is equipped with activation selenium mineral powder, the prepared selenium-enriched organic fertilizer that can be conducive to plant absorption.
For achieving the above object, the technical scheme is that
A kind of selenium-enriched organic fertilizer, it is mainly made up of following components proportioning by weight: chicken manure 70 ~ 90 parts, sheep stool 30 ~ 42 parts, 20 ~ 28 parts of pond sludge, 5 ~ 8 parts of Gecko excrement, 4 ~ 7 parts of Squama Manis excrement, fibrous biomass 35 ~ 50 parts, bean cake 30 ~ 35 parts, fishbone 10 ~ 15 parts, 3 ~ 6 parts of blackcurrant pigment shell, strain 5 ~ 8 parts, potassium humate 20 ~ 26 parts, activates selenium mineral powder 20 ~ 30 parts.
Further, described activation selenium mineral powder is by selenium ore grinding, make the selenium mineral powder of 50 ~ 100 orders, adding mass fraction by liquid-solid ratio 4 ~ 6ml/g is the ammonia of 2 ~ 3%, soak 48 ~ 72h, every 1 ~ 2h stirs once, and stirring after having soaked and being slowly added to dust technology adjustment is 6.2 ~ 6.8 to PH, is then sequentially added into Fe2O3And calcium acetate, stirring 1h, place in baking oven and dry, drying to moisture is 7 ~ 10%, it is thus achieved that activation selenium mineral powder.
Above-described selenium-enriched organic fertilizer, it is preferred that it is mainly made up of following components proportioning by weight: chicken manure 80 parts, sheep stool 36 parts, 24 parts of pond sludge, 7 parts of Gecko excrement, 6 parts of Squama Manis excrement, fibrous biomass 44 parts, bean cake 33 parts, fishbone 13 parts, 5 parts of blackcurrant pigment shell, strain 7 parts, potassium humate 23 parts, activate selenium mineral powder 28 parts.
Further, described fibrous biomass include one or more in straw, corncob, hay and dry rice straw.
Further, the Fe of addition2O3It is 1:1000 ~ 1100 with the mass ratio of selenium Ore；The calcium acetate added and the mass ratio of selenium Ore are 1:2000 ~ 2100.
Further, described strain includes at least two in lactic acid bacteria, yeast and bacillus subtilis.
The preparation method of a kind of selenium-enriched organic fertilizer, comprises the following steps:
(1) fishbone is cleaned, dry, be ground into powder, obtain fishbone powder；
(2) the blackcurrant pigment shell after fishbone powder, bean cake and pulverizing and fibrous biomass mix homogeneously are obtained compound, take strain to dissolve, join in compound, and the moisture being diluted with water to compound is 50 ~ 60%, fermentation vat ferments 8 ~ 10 days, obtains fermentation material A；
(3) in fermentation material A, add KOH solution, PH is regulated to 7.2 ~ 7.5, is subsequently adding potassium humate, stir, then the activation selenium mineral powder taking half adds in fermentation vat with chicken manure, sheep stool, pond sludge, Gecko excrement, Squama Manis excrement, stirs, mixed fermentation 8 ~ 10 days, obtains fermentation material B；
(4) in fermentation material B, add remaining activation selenium mineral powder, stir, obtain selenium-enriched organic fertilizer.
Further, described step (3) adds the activation selenium mineral powder of 1/2 ~ 2/3.
Further, in step (2) and (3), in preparing the sweat of fermentation material A and fermentation material B, every morning and afternoon are all each by material stirring 1 time.
The preparation method of above-described selenium-enriched organic fertilizer, has the advantage that
(1) present invention is by adding fowl and animal excrement, bean cake, fishbone, blackcurrant pigment shell, activation selenium mineral powder, comprehensive nutrition is provided for crop growth, especially selenite can be replaced to provide for crop growth and to be suitable for the selenium absorbed by plant, avoid selenite pollution to soil under being not completely absorbed state, be the increasing selenium method of safety and environmental protection.
(2) selenium mineral powder is through overactivation, wherein: add the activation that ammonia can be selenium on the one hand and provide the suitable alkaline environment of a PH, make selenium element convert to soluble state, additionally, add ammonia and also can form nitrogenous fertilizer in activation process, the crops absorption to selenium and nitrogen element can be promoted by synergism；Add Fe2O3Strengthen the absorbability to selenium with calcium acetate on the one hand and form complex state selenium, prevent selenium loss of elements, fertilizer can be made to discharge selenium element in soil slowly simultaneously, crops are avoided to occur concentrating excessive resorption to affect the phenomenon of its growth, iron salt and calcium salt can be provided for plant growing on the other hand, make nutrition balanced more comprehensively.
(3) present invention employs strain organic-biological matter and fowl and animal excrement are fermented, decompose the organic compound such as high molecular weight protein therein so that it is be degraded to and be suitable for the nutritional labeling being absorbed by plants, the crops absorbance to nutrient substance can be improved.
(4) feces produced by the chicken of artificial cultivation of the present invention, sheep, Gecko and Squama Manis, can feeding feedstuff containing selenium on a small quantity in artificial cultivation process, these fowl and animal excrements all contain the selenium element of trace, these raw material reasonable compatibilities are used by the present invention again, provide comprehensive nutrition for crops, and this is to turn waste into wealth, form Mode of Circular, meanwhile, activation selenium mineral powder is formed the structure of a uniform parcel by fowl and animal excrement, prevents the loss of selenium element further.
(5) present invention also added potassium humate, crops can be increased to the absorption of potassium and utilization rate, meanwhile, also can maintain the inorganic selenium contained in activation selenium mineral powder survival state in soil, make crops can obtain inorganic selenium and organic selenium simultaneously, improve its nutrition and constitute.
(6) one aspect of the present invention can be effectively improved the Se content in crops, agriculture and forestry organic waste material can be recycled on the other hand, have market popularization value widely, and Social and economic benef@is notable.
