    If it is transplanted, seedlings.

    Let him after half a month.

    Completely alive.

    You can get a little fertilized.

    Organic fertilizer in a broad sense: commonly known as farmhouse fertilizer, including a variety of animals, plant residues or metabolites, such as human and animal manure, straw, animal residues, slaughterhouse organic fertilizer, waste, etc.

    In addition, it also includes cake fertilizer (rapeseed cake, cottonseed cake, bean cake, sesame cake, castor cake, tea seed cake, etc.); Compost; manure; manure; biogas manure; Green manure, etc. It is mainly used as a means to improve the physical and chemical properties of the soil, promote the growth of plants and the circulation of the soil ecosystem. Some varieties of "organic fertilizer in the broad sense":

    Compost: all kinds of orange stalks, fallen leaves, grasses, animal and plant residues, human and animal manure as raw materials, mixed with each other in proportion or mixed with a small amount of soil for aerobic fermentation and decomposition of a kind of fertilizer. manure;

    The raw materials used for manure are basically the same as those used for compost, except that they are fermented under flooded conditions. Manure: refers to the manure of pigs, cattle, horses, sheep, chickens, ducks and other livestock and poultry and straw bedding made of fertilizer.

    Biogas fertilizer: In a sealed digester, organic matter is decomposed to produce by-products of biogas, including biogas liquid and residues. Green manure:

    Organic fertilizer. Use cultivated or wild green plants as fertilizer. Such as leguminous mung beans, broad beans, grass and trees, field cyanine, alfalfa, vetch and so on. Non-leguminous green manure includes ryegrass, fertile radish, small sunflower, manjianghong, water hyacinth, water peanut, etc.

    Crop straw: Crop straw is one of the important fertilizer varieties, and crop straw contains essential nutrients for crops, such as N, P, K, CA, S, etc. Under suitable conditions, through the action of soil microorganisms, these elements are mineralized and returned to the soil for crop absorption.

    Pure natural mineral fertilizers, including potassium mineral powder, phosphate rock powder, calcium chloride, natural potassium magnesium sulfate fertilizer and other natural substances that have not undergone chemical processing. These products must be certified organic and produced in strict accordance with organic standards before they can be used in organic farming. In addition, it is worth mentioning that in terms of potassium supplementation, CITIC Guoan's "organic natural potassium sulfate and magnesium sulfate fertilizer" can be selected to obtain organic product certification, which fills the domestic gap of organic natural mineral fertilizer and solves the problem of difficulty in potassium supplementation in organic agriculture.

    Cake fertilizer: rapeseed cake, cottonseed cake, bean cake, sesame cake, castor cake, tea seed cake, etc. Mudman:

    Unpolluted river mud, pond mud, ditch mud, port mud, lake mud, etc.

    Organic fertilizer in the narrow sense.

    Organic fertilizer in a narrow sense: refers to the use of various animal wastes (including animal manure; animal processing waste) and plant residues (cake fertilizers; crop straw; Defoliation; Branches; peat, etc.), using physical, chemical, biological or a combination of the three, after a certain processing technology (including but not limited to stacking; High temperature; Anaerobic, etc.), eliminating the harmful substances (pathogenic bacteria, insect pests, weeds, seeds, etc.) to meet the harmless standards and the formation of a type of fertilizer that meets the relevant national standards (NY 525-2002) and regulations.

    In a few words, composting is a natural biological process that converts organic matter into a stable, humus-like product under controlled conditions. The composting process is mainly broken down into simple compounds by microorganisms, including bacteria and fungi, actinomycetes.

    Composting is an aerobic fermentation process, which means that microorganisms need oxygen to do it.

    Compost is a kind of organic fertilizer, contains nutrients are relatively rich, and the fertilizer effect is long and stable, is conducive to promoting the formation of soil solid structure simultaneously, can increase the ability of soil water retention, heat preservation, air permeability, fertilizer retention, and can make up for the single nutrient contained in chemical fertilizer with chemical fertilizer, long-term single use of chemical fertilizer makes the soil compacted, water retention, fertilizer retention performance decreases defect. Composting is an organic fertilizer made by composting and decomposing various plant residues (crop straw, weeds, leaves, peat, garbage and other wastes, etc.) as the main raw materials.

    (1) Nitrogen and phosphorus and other nutrients are polluted, water eutrophication, algae grow in large quantities, oxygen in the tissue air is transferred to the inside of the water body, the dissolved oxygen in the water body is reduced, the dead algae residue is decomposed by aerobic bacteria, and the dissolved oxygen in the water body is further consumed, the water body is in an anaerobic state, a large number of aquatic animals and plants die due to lack of oxygen, and the river ecosystem is destroyed.

    2) Organic matter pollution, aerobic bacteria decomposing organic matter in the water body multiply, bacteria consume dissolved oxygen in the water body in the process of decomposing organic matter, the oxygen consumption rate is greater than the natural reoxygenation rate of the water body, and the dissolved oxygen of the water body decreases until it is in an anaerobic state, at this time, the decomposition process of organic matter is completed by anaerobic bacteria, and aquatic animals and plants also die because of lack of oxygen.

    3) Contamination by toxic substances, usually because the toxic effects of these substances lead to the death of aquatic organisms.

    4) Suspended solids (SS) pollution, on the one hand, makes the water body turbid, and it is difficult for sunlight and oxygen to enter the water body, so that the dissolved oxygen inside the water body is gradually depleted; Suspended solids, on the other hand, can block the respiratory organs of aquatic animals, causing them to suffocate to death.

    1. What is organic fertilizer?

    Traditional organic fertilizer is defined as "fertilizer made by accumulating or stirring rice straw, rice husks, tree bark, animal excrement and other organic matter of animals and plants (except sludge and internal organs of fish and shellfish)".

    The decomposition process of organic fertilizer is: in the aerobic state of accumulation, stirring and ventilation, microorganisms are used to decompose the organic matter in the raw materials, and the heat generated by decomposition can evaporate the water, which can kill pathogenic bacteria, parasite eggs and weed seeds, which is a safe, hygienic and stable process of organic matter.

    Second, the fertilization effect.

    If organic fertilizer is mixed in the field, the organic fertilizer will become food for microorganisms, which is conducive to the reproduction of microorganisms. Organisms of different sizes, such as bacteria, fungi, insects, and earthworms, begin to move.

    At this time, through the mucus secreted by microorganisms, the ionic structure becomes a small clump in the microscopic soil. Such a soil becomes an agglomerate structure, which is very suitable for the growth of crops.

    Because of the space between the dumplings and the dumplings, they can make ventilation and drainage good. At the same time, the dumplings can also store water one by one, and the water retention is also very good.

    There are many microorganisms in such soils, and they form a balance that pushes against each other. As a result, there will be no malignant microorganisms to multiply, just like the human gut, where beneficial microorganisms are balanced with harmful microorganisms. At the same time, crop damage mixed with organic fertilizer can increase the risk of pest and disease infestation.

    Refers to nitrogenous materials that are mainly applied to plants and animals and applied to the soil to improve plant nutrients, such as human manure, livestock and poultry manure, compost manure, green manure, urban waste, soil inoculum, etc.

    Of course not, and neither are the non-fermented ones.
