Three types of fertilizers for green food production

The production of green foods also imposes various restrictions on the fertilizer used. What are the allowed fertilizers?

I. Farmyard fertilizers. Refers to fertilizers containing a large number of biological substances, animal and plant residues, excrement, biological waste and other substances.

1. Composting. An organic fertilizer made of various straws, fallen leaves, human and animal dung as raw materials mixed with a small amount of soil.

2, Feifei. The material used is basically the same as compost, but it is only fermented under flooding conditions (off gas).

3, manure. Refers to pigs, cattle, horses, sheep, ducks and other livestock and poultry excrement and straw dunnage made of fertilizer.

4, biogas fertilizer. In a sealed biogas digester, organic matter decomposes to generate by-products of biogas under anaerobic conditions.

5, green manure. The use of cultivated or wild green plants as fertilizer can be divided into two major categories of leguminous and non-fabric legumes: mungbean, broad bean, and turfgrass. Non-legume green manure is most commonly used in grasses such as ryegrass; crucifers such as fertile radishes.

6, crop straw. Crop stalks contain a considerable amount of nutrients (n, p, k, ca, s, etc.) that, under appropriate conditions, are mineralized by the action of soil microorganisms and returned to the soil for crop absorption and utilization.

7. Mud fertilizer. Unpolluted river mud, pond mud, gully mud, mud in the harbor, lake mud and so on.

8, cake fat. Rapeseed cake, cottonseed cake, bean cake, sesame cake, peanut cake, castor cake, tea seed cake, etc.

Two. Commercial fertilizers.

1, commodity organic fertilizer. Refers to a wide range of biological substances, animal and plant residues, excrement, biological waste and other materials processed as raw materials, such as fertilizer.

2, humic acid fertilizers. Refers to peat (charcoal), lignite, weathered coal and other fertilizers containing humic acids.

3, microbial fertilizer. Refers to the production of active microbial preparations by culturing with specific microbial strains. The life activities of specific microorganisms can improve plant nutrition or produce plant growth hormone to promote plant growth.

4, semi-organic fertilizer (organic compound fertilizer). Fertilizers made of organic or inorganic substances mixed or compounded. After detoxification treatment of poultry manure, add appropriate amounts of zinc, manganese, boron, molybdenum and other trace elements made of fertilizer.

5, inorganic (mineral) fertilizer. The minerals are made into fertilizers in the form of inorganic salts by physical or chemical industry methods. Mineral potassium and potassium sulfate; Mineral phosphate (phosphate rock); Calcined phosphate (calcium magnesium phosphate, defluorinated phosphate); Limestone: Limited use in acidic soils;

6, foliar fertilizer. Refers to fertilizers that are applied to the leaves of plants and can be absorbed and used by the fertilizer. Fertilizers must not contain chemically synthesized growth regulators. The trace element fertilizer is mainly composed of cu, fe, mn, zn, b, mo and other trace elements and beneficial elements. Plant growth assistant fertilizers are fertilizers formulated with natural organic fertilizer extracts or broths inoculated with beneficial bacteria plus some humic acids, alginic acids, amino acids, vitamins, and sugar.

Three. Other fertilizers.

1, including foods without synthetic additives, organic by-products of the textile industry.

2. Including fish preservative-free fish residue, cattle wool waste, bone meal, amino acid residues, bone glue residue, etc.
