Description

Ecological organic fertilizer

The present invention relates to technical field of agricultural fertilizers, particularly ecological organic fertilizer.

Along with the raising of agriculture production industrialization degree, chemical fertilizer uses more and more widely, though the use of chemical fertilizer can improve the output of farm crop greatly, also causes the floor panel junction phenomena to be on the rise.For this reason, many scientists are in order to address this problem, many kinds of fertilizers have been invented, as the disclosed a kind of fertilizer of Chinese patent 94114139.X, be by chicken manure, high-quality phosphate fertilizer, vitriolate of tartar or Repone K with 40～50: 30～40: 20% mixed stirs makes particulate state, it has the advantage that fertilizer efficiency is fast, fertilizer efficiency is high, discharges fast shortcoming but this fertilizer exists frowziness, bacteria content height, nitrogen element.

The purpose of this invention is to provide a kind of odorless, aseptic, nitrogen element discharges slow ecological organic fertilizer.

For realizing that the technical scheme that the object of the invention adopted is: ecological organic fertilizer is made by following method 70-80 part (weight) water content is eaten bran, the 1-3 part unslaked lime mixing secondary fermentation at 60-65% of bacterium culture material, 10-20 part water content less than 50% chicken manure and 20-30 part, and the pH value of material remains between the 8-8.5 during fermentation; After fermentation finishes, adding 2-3 part is carried out the deodorizing processing by the reodorant of 26 parts of ferrous sulfate, 4 parts of sal epsom, 100 parts of water preparations, add PH conditioning agent that 1-1.4 part is made of 2 part of 40% phosphoric acid solution and 1 part of 60% sulphuric acid soln again and regulate the pH value of material after the deodorizing, its pH value is controlled between the 4-6, and then the disinfectant that adding 0.5-2 part is made up of 37% formalin carries out sterilization, adding 2-10 part urea at last stirs, drying, routine techniquess such as pulverizing or granulation promptly can be made into finished product.

The characteristics of each component used in the present invention are:

(1), chicken manure: low, the nitrogenous rate height of carbon content rate and easily being decomposed by fermentation in the fowl and animal excrement of being in has quick-acting as fertilizer.

(2), mushroom bacterium culture material: contain abundant organic matter and mineral nutrient element and hormone, enzyme in the useless mushroom bacterium culture material, these materials have short long and but characteristic of disease to plant.

(3), ferrous sulfate: have deodorization, can increase sulphur, source of iron in the fertilizer again.

(4), sal epsom: make the stablizer of ferrous sulfate in the present invention, can increase sulphur, magnesium source in the fertilizer again.

(5), phosphoric acid and sulfuric acid: regulate the pH value of raw material, make urea again--the solidifying agent of formaldehyde condensation reaction and basic raw material played short fertile effect has increased the phosphorus in the fertilizer, sulphur source simultaneously again.

(6), urea is made urea in the fertilizer--the nitrogenous source of formaldehyde condensation products.

(7), formaldehyde: make the sterilant of fertilizer, and produce condenses with urea reaction.

(8), lime, bran: lime is regulated the pH value of raw material, makes sterilant again, increases the calcium source in the fertilizer.Brans etc. are done the agent of becoming thoroughly decomposed of urging of raw material, provide organic, increase the potassium source for fertilizer simultaneously.

Can derive the present invention from above proportioning raw materials and have following advantage:

(1), transform soil, recover soil fertility, be applied to the field of using chemical fertilizer all the year round, can eliminate and harden, recover soil fertility.

(2), raw material abundance, cheap and easy to get.Chicken manure, useless mushroom bacterium culture material source abundance.

(3), technology is simple, processing is rapid.Basic raw material only needs through short-term spontaneous fermentation, and fuel saving both can be got on the job with indigenous methods.Also be convenient to industrialized production.

(4), processing of waste, protection environment, the present invention has handled the refuse of a large amount of contaminate environment that breed, plantation produce effectively.Work in-process has added deodorizing, disinfectant in addition, and stink is little, and the finished product that makes is an odorless fertilizer, and storage stability is good.

(5), fertilizer efficiency height, purposes are wide.It is comprehensive that the present invention contains fertilizer element, comprises various macroelement and trace element that growth and development of plants is required.Containing urea in the product--formaldehyde condensation products can slow release nitrogen fertilizer, continuously release nitrogen and can reach for many years, fertilizer efficiency period is long, therefore, product is except being used for fertilisings such as crop, vegetables, flowers, still can replace " nutritive medium " to make the solid fertilizer of soilless culture, thereby improved the quality of soilless culture, reached " standard of green product ", and then promoted popularizing of this high-new technology farming cultivation technique.

(6), ecologic effect (A) plant protection effect: can suppress disease and pest after using and take place, improve percentage of germination and prevent mashed root.(B) dematuration: can shorten vegetative period after using, in advance results.(C) production-increasing function: as be applied to paddy rice than common chemical fertilizer volume increase 40%, being used for the greenhouse tomato and can increasing production 50%, pol on average improves 1.5 times.

Embodiment: ecological organic fertilizer, make by following method:

(1), 75 parts of (weight) chicken manures (or other ight soil) are removed foreign material (water content is less than 50%) such as sandstone, eating bacterium culture material, 15 parts of water content with 25 parts pulverizes standby at the bran of 60-65% (or tangerine cake, straw).
