Description

A kind of ecological organic fertilier and preparation method thereof
Technical field
The invention belongs to technical field of fertilizers, and in particular to a kind of ecological organic fertilier and preparation method thereof.
Background technology
Organic, pollution-free food is described as " 21st century food ", represents the new trend of contemporary food development, and China is gone through To pay attention to effect of the food to health, popularization, constantly bringing forth new ideas for product and the conducting vigorous propaganda for news media of nutritional knowledge * make People focus more on health and the relations of meals, and the requirement to food is towards the side of organic, green, nutrition and health care, function curative effect To development, the dense atmosphere of " healthy consumption " has been formed.
With the formulation of some international and national organic standards, developed country starts to pay attention to exploitation organic agriculture, and encourages Peasant produces conversion from conventional agriculture to organic agriculture.So-called organic agriculture refers to manure use material and life in agricultural production Thing insecticide replaces chemical fertilizer and chemical insecticide, while carrying out arable land rotation system, so as to reduce environmental pollution, improves soil fertilizer Power, produces the emerging agricultural of healthy food i.e. organic food, pollution-free food.
China's livestock and poultry breeding industry just progressively develops to intensive, specialized direction, due to only paying attention to breeding production, ignores poultry The integrated treatment of poultry manure, the phenomenon that feces of livestock and poultry huddles disorderly row is more and more universal, and the pollution to environment is aggravated year by year, is caused perhaps Many plants turn into pollution sources.Relevant research confirms that feces of livestock and poultry enters the turnover rate of water body up to 25~30%.China's agricultural The turnover rate of nitrogenous fertilizer is general, and 8~20%, phosphate fertilizer turnover rate is about 5%, and in feces of livestock and poultry nitrogen, phosphorus being respectively of number of dropouts Fertile number of dropouts 122% and 132%.Pollution from livestock and poultry is increasingly becoming the main pollution threat at China water source, only in Shanghai, should The contaminant capacity of industry just accounts for the 36% of Huangpu River pollutional load.
In the fowl and animal excrements such as the cow dung that process is not become thoroughly decomposed directly are manured into soil, meet water by fermentation and produce high temperature, easily burn root Burn seedlings;A large amount of activities due to harmful microorganism participation fermentation, consume oxygen, cause soil anoxic, it will cause growth is weaker Plant death;Cow dung just can produce stink in fermentation, and fly maggot of soliciting, damage to crops growth, stink can also pollute environment;Excrement In contain substantial amounts of uric acid, without conversion of becoming thoroughly decomposed, directly contact seedling, it will suppression seedling early growth;The excrement not become thoroughly decomposed exists Fermented in soil, fight for the original nitrogen nutrient of soil, cause instantaneous nitrogen stress in Soil Micro-environment, influence seedling early growth.So Processing must be further processed to these fowl and animal excrements, the organic fertilizer of ecology is made.
The content of the invention
In order to solve the above problems, the present invention provides a kind of ecological organic fertilier, including following components in percentage by weight:It is dynamic Thing excrement 50-70%, probiotics 2-5%, powder of straw 15-30%, other auxiliary materials 10-20%.
Preferably, other described accessory packages contain the component of following parts by weight:Dregs of beans 60%-80%, humic acid 20%-40%.
Preferably, a kind of ecological organic fertilier, including following components in percentage by weight:Animal excreta 60%, probiotics 3%, straw Stalk powder 22%, dregs of beans 10%, humic acid 5%.
Preferably, the animal excreta is the one or more in sheep manure, cow dung, pig manure, chicken manure.
A kind of preparation method of ecological organic fertilier, comprises the following steps:
(1)Fertilizer each component is mixed, and adds strain;
(2)Stir, then carry out solid fermentation;
(3)Drying;
(4)Crush, granulate;
(5)Sieving;
(6)Low temperature drying, cooling;
(7)Encapsulation.
Preferably, turning after fermentation a period of time, adds strain and continues to ferment again.
Preferably, the method for addition strain is:Strain is diluted with water, cultivation 8-12 hours, and the bacterium solution after cultivation is uniform It is sprayed on fertilizer.
Preferably, the humidity of solid is 50%-70% before fermenting.
Preferably, the fermentation temperature of the fermentation is not higher than 65 degrees Celsius.
Preferably, the strain is EM bacterium.
The beneficial effects of the invention are as follows:
(1)The beneficial effect of organic fertilizer:
1. soil nutrient status is improved:After organic fertilizer is manured into soil, by the decomposition and inversion of microorganism, becoming crop can inhale The available nutrient utilized is received, soil supplying nutrient capability is improved.Organic acid in organic fertilizer forms stability very with calcium, magnesium, iron, aluminium Strong complex compound, so as to reduce phosphorus fixation and iron, the murder by poisoning of aluminium.Organic acid and its esters there is buffering to make soil acidity or alkalinity With the buffer capacity of raising soil.Fertilizer speed relaxes, and fertilizer efficiency is too fast unlike chemical fertilizer, also unlike traditional organic fertilizer Fertilizer efficiency is excessively slow.
2. improved soil structure:The humus that bio-organic fertilizer is formed in the presence of microorganism is a kind of organic gel Grogs, can be combined together by body, form stable crumb structure, increase the aeration and water penetration of soil, improve soil Water, fertilizer, air and heat situation, are conducive to plant growth.Do base fertilizer, topdress, sow, root dipping.
3. microbial activities is promoted:Bio-organic fertilizer provides substantial amounts of energy substance for microbial activities, not only can be with Accelerate organic matter the decomposition of contained nutrient, conversion and to discharge in itself, and contribute to the mineral nutrient such as original phosphorus, potassium in soil Release, accelerate soil in small biological cycle process, be conducive to the further raising of soil effective fertility.
(2)The beneficial effect of preparation method:
1. under the decomposition of bacterium, fermentation does not result in loss to the nutrition in animal wastes, can promote on the contrary big in excrement Transformation from molecule nutrient to small molecule nutrient and derive the materials of more favourable plant growths, such organic fertilizer with it is traditional Rural area compost ratio makes plant be more easy to absorption, also enhances the quick-acting of organic fertilizer, and can eliminate stink, kills having in excrement Fall ill poison, germ, reach harmless treatment standard.
2. turning reaches ventilative oxygen supply effect, secondary to spray culture bacterium solution, can not only shorten fermentation time, and can be with Improve the quantity of probiotics in the quality of organic fertilizer, increase organic fertilizer.
