Abstract

The invention discloses a slow-release mixing fertilizer which is prepared from the following raw materials in parts by weight: 70 to 80 parts of soybean cake, 30 to 34 parts of corncob, 6 to 9 parts of bamboo shoot shell, 13 to 16 parts of bagasse, 4 to 5 parts of maize meal, 2 to 3 parts of lime, 23 to 25 parts of slow-release urea, 12 to 15 parts of potassium oxide, 2 to 3 parts of magnesium sulfate, 1 to 2 parts of zinc sulfate, 1 to 2 parts of sodium selenite, 1 to 2 parts of manganese sulfate, 2 to 3 parts of borax, 1 to 2 parts of manganese sulfate, 1 to 2 parts of polyvinyl alcohol, 3 to 4 parts of EM (Effective Microorganism) agent, 4 to 6 parts of coating agent and a proper amount of water. The slow-release mixing fertilizer is prepared through the fermentation of an organic fertilizer and an inorganic fertilizer, so that the slow-release mixing fertilizer has the common characteristics of the organic fertilizer and the inorganic fertilizer, namely that the slow-release mixing fertilizer is not only rich in organic substances so as to provide necessary nutrient elements needed by the growing development of a crop to improve the yield and quality of the crop but also has the functions of improving the soil property and the moisture and fertility preservation of the soil. The prepared fertilizer is long in fertilizer efficiency and has a certain promotion function for the environment. The magnesium sulfate added into the fertilizer has the function of improving the soil with magnesium deficiency.

Description

A kind of slowly-releasing mixes fertilizer and preparation method thereof

Technical field

The present invention relates to a kind of technical field of fertilizers, particularly a kind of slowly-releasing mixes fertilizer and preparation method thereof.

Background technology

At present, the chemical fertilizer that China's fertilizer is mainly comprised of N, P, the large inorganic elements of K tri-, this chemical fertilizer can meet the growth needs of farm crop at short notice.But life-time service can make soil aggregate be destroyed, easily cause soil compaction, soil property hardening, thereby affect the growth of farm crop, the decline of quality, cause vicious cycle.Though simultaneously fertilizer is rich in organic matter, nutrient discharges slowly, cause farm crop absorb slow, fertilizer efficiency is low, between various available nutrient, do not reach active balance, due to the not science of fertilizer formula of farm crop, cause the output of farm crop not high, quality also can not get improving.Fertilizer of the present invention, adopts effective combination of organic fertilizer and mineral manure, and scientific matching can meet the growth demands of farm crop to greatest extent.

Summary of the invention

Fertilizer object of the present invention is to provide a kind of slowly-releasing to mix fertilizer and preparation method thereof.

Technical scheme of the present invention is as follows:

Fertilizer is made by the raw material of following weight part: soybean cake 70-80, corn cob 30-34, bamboo shoot shell 6-9, bagasse 13-16, Semen Maydis powder 4-5, lime 2-3, slow-release carbamide 23-25, potassium oxide 12-15, magnesium sulfate 2-3, zinc sulfate 1-2, Sodium Selenite 1-2, manganous sulfate 1-2, borax 2-3, manganous sulfate 1-2, polyvinyl alcohol 1-2, EM microbial inoculum 3-4, coating agent 4-6, water are appropriate;

Described coating agent is made by the raw material of following weight part: double pentaerythritol methacrylate 10-12, Silane coupling reagent KH-570 2-3, nano-sized carbon 0.1-0.2, medical stone powder 1-2; Its preparation method is that each raw material is mixed, and grinding distribution evenly and get final product.

The concrete steps of the preparation of fertilizer are as follows:

(1) soybean cake, corn cob, bamboo shoot shell are pulverized to slagging, mix with bagasse to add in suitable quantity of water and soak 2-3 days, obtain mixture;

(2) Semen Maydis powder is added in appropriate warm water and mixed, stir, access EM microbial inoculum, places after 1-2 days in the mixture with step 1, seals, and carries out anaerobic fermentation 20-30 days, turning 5-6 time under natural condition;

(3) by slow-release carbamide, potassium oxide heating and melting, add lime to grind 5-10 minute, obtain mixed solution;

(4) magnesium sulfate, zinc sulfate, Sodium Selenite, manganous sulfate, borax, manganous sulfate, polyvinyl alcohol are added in suitable quantity of water, be stirred well to completely and dissolve, after mixing with the mixed solution of step 3, join in the material that the fermentation of step 2 completes, stir, carry out Secondary Fermentation 5-8 days, turning during this time 2-3 time;

(5) material after step 4 has been fermented mixes with other remaining component, stirs, dry, and granulation.

Beneficial effect of the present invention:

Fertilizer of the present invention, the fertilizer that adopts organic fertilizer and mineral manure to make afterwards by fermentation, there is the common feature of organic fertilizer and mineral manure, not only be rich in organic matter, provide crop growthing development required necessary nutritive element, improve the quantity and quality of plant, also there is the soil property of improvement, improved the effect of soil water-reataining fertilizer-keeping.The fertilizer of making, fertilizer efficiency is long, also for environment, has certain promoter action, and the magnesium sulfate wherein adding is the effect with the soil of improvement magnesium deficiency.

Specific embodiments

Below in conjunction with following embodiment, the present invention is described in further detail:

The raw material that takes following weight part (kg) is made: soybean cake 75, corn cob 32, bamboo shoot shell 7, bagasse 14, Semen Maydis powder 4, lime 2, slow-release carbamide 24, potassium oxide 3 magnesium sulfate 2, zinc sulfate 1, Sodium Selenite 1, manganous sulfate 1, borax 2, manganous sulfate 1, polyvinyl alcohol 1, EM microbial inoculum 3, coating agent 5, water are appropriate;

Described coating agent is made by the raw material of following weight part (kg): double pentaerythritol methacrylate 11, Silane coupling reagent KH-570 2, nano-sized carbon 0.2, medical stone powder 1; Its preparation method is that each raw material is mixed, and grinding distribution evenly and get final product.

The preparation method's of fertilizer concrete steps are as follows:
