State 50% organic matter fertilizer be using feces of livestock and poultry as primary raw material, it is fermented it is decomposed after be made, the content of organic matter >=50%.
Wherein, organic matter fertilizer be using feces of livestock and poultry as primary raw material, it is fermented it is decomposed after be made, in the embodiment of the present invention,
Feces of livestock and poultry can select cow dung or sheep dung, make content >=50% of organic matter in 50% organic matter fertilizer.
Ground phosphate rock is a kind of natural untreated phosphate, and when being applied in soil, ground phosphate rock will become the one of soil
Part, once using ground phosphate rock does not leach out, it can be stayed always in the soil, and until being absorbed by plants, ground phosphate rock is without nocuousness
Acid, the growth of the bacterium and earthworm in soil can be promoted, have the function of improve soil.Ground phosphate rock has grey or brown two
Kind, itself does not have smell, and main component is fluor-apatite, and the phosphorus pentoxide containing 10-35%, wherein the phosphorus of 3-5% is dissolved in weak
Acid can be absorbed by crops utilization.The embodiment of the present invention uses phosphorus pentoxide content for the ground phosphate rock of 16-22%, and is preparing
Before the present invention, being crushed to granularity is 90-120 mesh.
Potassium dihydrogen phosphate can be suitable for the work of the almost all types such as all types of industrial crops, grain, melon fruits and vegetables
Object proves that there is potassium dihydrogen phosphate significant increasing both production and income, the amount of changing to optimize by practical application effect of the various regions to all types of crops
Many excellent effects such as quality, resistant to lodging, disease and insect resistance, prevention and treatment early ageing, and have and overcome the root system aging of plant growth later period
Malnourished effect caused by absorbability decline.Potassium dihydrogen phosphate belongs to high concentration phosphorus potassium Was Used compound fertilizer,
In contain phosphorus pentoxide 52% or so, containing oxidation dipotassium 34% or so.
Biological enzyme is the organic matter with catalytic action generated by living cells, and composition is mostly protein, containing a small amount of
RNA, biological enzyme are generated from organism, it has special catalysis, make catalyst with enzyme, the catalytic efficiency of enzyme is
The 10 of general organic catalyst7-1013Times.A kind of enzyme can only be catalyzed the chemical reaction of a substance, i.e., enzyme be only capable of promoting it is specific
The catalyst that compound, specified chemical key, specified chemical change.Enzymic catalytic reaction catalyst not as need high temperature, high pressure,
The drastic conditions such as strong acid, highly basic, and can be carried out under relatively mild room temperature, normal pressure.Enzyme can improve chemistry as a kind of catalyst
The rate of reaction, main cause are reduction of the activation energy of reaction, make reaction be easier to carry out, and enzyme before the reaction after theoretically
It is not consumed, so going back recoverable.
Sepiolite is a kind of hydrous magnesium silicate of threadiness, typically exhibits white, light gray or light yellow.Sepiolite crystal
For layer chain structure, which makes it have very big surface area, and then makes it have good absorption property, rheological characteristic
Energy and catalytic performance, have the good condition for making catalyst carrier, itself can also be used as the catalyst of certain reactions.This hair
In bright embodiment, biological enzyme and sepiolite synergistic effect can be improved phosphorus in organic matter and rock phosphate in powder in the soil effective
