Which category and quality determination rules of bio organi
Basic introduction of various bio organic fertilizers
Now, with the continuous development of science and technology, through the artificial pure culture technology of beneficial bacteria, using scientific refining, we can produce a variety of different varieties of bio organic fertilizer, which can improve soil quality, reduce environmental pollution, increase fertilizer efficiency and so on. The following is the basic introduction of eight kinds of bio organic fertilizer.
Organic fertilizer: mainly refers to all kinds of animals and plants, after a period of fermentation after the formation of fertilizer (including processed rapeseed cake, there is no smell). Organic fertilizer contains a large number of biological substances, animal and plant residues, excrement, biological waste and other substances. Application of organic fertilizer can not only provide large-scale nutrition for crops, but also has long fertilizer efficiency. It can increase and renew soil organic matter, microbial reproduction, soil physical and chemical properties and biological activity, which is the main nutrient source of green food production.
Compost: it is a kind of organic fertilizer made of various kinds of orange stalks, fallen leaves, grass, animal and plant residues, human and animal manure and a small amount of soil.
Composting: the raw materials used for composting are basically the same as composting, but they are fermented under flooding conditions.
Stable manure: refers to the manure and straw compost of pigs, cattle, horses, sheep, chickens, ducks and other livestock and poultry.
Biogas fertilizer: in the sealed biogas digester, the by-products produced by the decomposition of organic matter include biogas liquid and residue.
Green manure: the use of cultivated or wild green plants as fertilizer. Such as mung bean, broad bean, sweet clover, Sesbania, alfalfa, vetch and so on. Non legume green manure includes ryegrass, radish, sunflower, mangjianghong, water hyacinth, water peanuts, etc.
Cake fertilizer: rapeseed cake, cottonseed cake, bean cake, sesame cake, castor cake, tea seed cake, etc.
Mud and fertilizer: unpolluted river mud, pond mud, ditch mud, harbor mud, lake mud, etc.
Bio organic fertilizer will be the main development trend of agricultural fertilizer in the future.
Quality determination rules of bio organic fertilizer
Bio organic fertilizer may be unfamiliar to everyone. Here is a brief introduction: bio organic fertilizer is an organic fertilizer made from organic solid waste (including organic waste, straw, livestock manure, cake, agricultural and sideline products and solid waste from food processing) after microbial fermentation, deodorization and complete decomposition.
The rounding off of product technical indexes in this standard shall comply with GB 8170; The qualification of product quality shall comply with the provisions of rounding off value comparison method in GB / T 1250.
Products with any of the following terms are qualified products
a. The technical indexes of the products meet the requirements of the standards;
b. In the appearance, pH value and moisture test items of the product, one item does not meet the standard requirements, while other indicators of the product meet the standard requirements.
Products with any of the following terms are unqualified products
a. The number of viable bacteria in the product does not meet the standard requirements;
b. The content of organic matter does not meet the standard requirements;
c. The number of fecal coliform did not meet the standard;
d. The egg death rate of Ascaris lumbricoides did not meet the standard;
e. Any content of as, CD, Pb, Cr, Hg does not meet the standard requirements;
f. The appearance, pH value and moisture content of the product do not meet the requirements of the standard.
Bio organic fertilizer plays an important role in the growth of crops and has potential market, so the criteria of bio organic fertilizer are relatively important.
