Abstract

The present invention relates to multielement high-efficiency organic mixed fertilizer. Stems and leaves of the plants, barnyard manure, bone powder, water solution of rare earth, water solution of trace elements, etc. are used as raw materials and are evenly mixed, the raw materials are dried after humification treatment and are added with right amount of nitrogen phosphorus chemical fertilizer, and thus, the present invention is made by disintegrating granulation. The fertilizer comprises more than 30% of organic matters, more than 20% of nitrogen, phosphorus and potassium, rare earth elements and trace elements which are required by the growth of the plants, such as iron, calcium, magnesium, molybdenum, copper, zinc, boron, manganese, etc. The fertilizer has the advantage of fast and long fertilizer effect, and has the effects of improving aggregate structures of soil and increasing soil fertility.

Description

A kind of production method of organic composite fertilizer

The invention belongs to a kind of organic composite fertilizer.

At present, the fertilizer that uses on the agricultural is divided into two kinds in organic fertilizer and chemical fertilizer.Chemical fertilizer is rich in plant nutrients such as nitrogen, phosphorus, potassium, is a kind of readily avaiable fertilizer, can promote crop growth rapidly, but its fertilizer efficiency time is short, and nutrient is single relatively, and life-time service can cause soil compaction.Usually the organic fertilizer of using mainly is a farm manure, contain organic and multiple nutrients composition, it is controlled availability fertilizer, the life-time service structure of improving the soil, but the content that the multiple nutrients composition that its fertilizer efficiency is slow, crop needs has is very low even do not have, and stores, transports, will expend more human and material resources, financial resources when using.

The objective of the invention is to overcome the above-mentioned shortcoming that farm manure, chemical fertilizer exist, provide a kind of and collect farm manure, the chemical fertilizer advantage is the novel organic composite fertilizer of one.

To achieve these goals, the present invention is achieved through the following technical solutions:

With main raw material---plant stems and leaves is cut into chip, be placed in the enough big container, pour animal excrement (perhaps chemical nitrogen fertilizer), ground phosphate rock, bone meal, sylvite then into, and, add the mixed liquid (as: salts solutions of iron, zinc, copper, calcium, boron, molybdenum etc.) of rare earth aqueous solution and trace element according to the situation of soil and the needs of crop.Above-mentioned raw materials carries out humification and handles through after evenly mixed---and under 25～70 ℃ of temperature, deposit more than one month, make its decomposition fermentation.Be to improve the effect that humification is handled, added animal excrement can be made two kinds of strain liquids earlier---high temperature cellulose-decomposting bacteria liquid (claim not only high-temperature strain liquid) and normal temperature carbon nitrogen decomposer liquid (but also claiming the normal temperature strain liquid).High temperature cellulose-decomposting bacteria liquid is with horsehit or mule, donkey excrement, after 5～15 times water dilution, at 50～80 ℃ of temperature bottom fermentations more than four days and make; Normal temperature carbon nitrogen decomposer liquid is the fecaluria with poultry, fowl, after 5～20 times water dilution, makes more than 15 days at 25～35 ℃ of bottom fermentations.

After humification is handled, take out reactant, oven dry adds the proper N phosphatization fertilizer more then, and final powder is broken into powder or makes particulate state.The raw material that is added---rare earth aqueous solution and the mixed liquid of trace element can add before the detritus processing, also can add before humification is handled back, pulverizing.

Organic composite fertilizer of the present invention, abundant raw material, with low cost, contain organic more than 30% in the fertilizer, nitrogenous, phosphorus, potassium total amount are more than 20%, contain rare earth element 0.5～2.0 ‰ that to regulate the crop physiology reaction, and contain moderate-element and trace elements such as the necessary calcium of plant growth, magnesium, boron, iron, zinc, copper, molybdenum.After this fertilizer was used, fertilizer efficiency was fast and lasting, the good result that life-time service has improved soil nodule structure, increases soil fertility, and have the transportation of being easy to, be convenient to store, use advantages such as convenient.

Be one embodiment of the present of invention below---make 1.8 tons of compoiste fertilizers with 1 ton of dried corn stalk leaf.

1, preparation bacterial classification

(1) preparation high temperature cellulose-decomposting bacteria liquid: 1 kilogram of fresh horsehit is placed in 15 kg of water, stirs, cultivated 6 days down at 65 ℃.

(2) preparation normal temperature carbon nitrogen decomposer liquid: 7 kilograms of cow dungs, 7 kilograms of pig manures, 1 kilogram of chicken manure is put into 300 kg of water, stirs, and cultivates 20 days down at 25～30 ℃.

2, preparation rare earth aqueous solution and trace element water-soluble liquid

(1) rare earth aqueous solution: being made into concentration with agricultural nitrated rare earth is 600 kilograms of 2 ‰ earth solutions.

(2) trace element water-soluble liquid: in 400 kg of water, put into 10 kilograms of zinc sulfate, 10 kilograms of manganous sulfates, 4 kilograms of boric acid, 12 kilograms of ferrous sulfate, 60 kilograms of sal epsom, 2 kilograms of ammonium molybdates, evenly mixed then.

3, batch mixing:

In 4 meters long, 2 meters wide, 2 meters dark cement tubs, put into following raw material:

(1) is cut into 1 ton on corn stalk leaf below 2 centimetres.

(2) bicarbonate of ammonia is 25 kilograms; 60 kilograms of bone meal; 150 kilograms in ground phosphate rock; 60 kilograms of potassiumphosphates.

(3) above-mentioned rare earth aqueous solution, trace element water-soluble liquid, high temperature cellulose-decomposting bacteria liquid and normal temperature carbon nitrogen decomposer liquid are mixed.

4, humification is handled

After above-mentioned raw materials stirs, seal the cement tub opening with straw screen or mat, earth in cement tub.Along with the decomposition gradually of corn stalk leaf, the temperature in the groove also progressively rises, and treats that constant temperature when temperature is raised to 65～70 ℃ keeps 7 days (with ventilation and take off the way temperature control of lid).With earth the cement notch is obturaged later on, is made that temperature remains on 25～30 ℃ in the groove, in 3 months pits the corn stalk leaf organize broken decomposition, color is light/dark balance.

5, oven dry, spike, pulverizing

Reactant after the humification processing is taken out; be put into and dry in the drying room to moisture below 10%; add 180 kilograms in urea, 280 kilograms of calcium superphosphate then; be ground into powdery; after stirring; and then make the particulate state fertilizer of 2～4 millimeters of diameters with nodulizer, pack is standby after the thorough drying.
