Description

A kind of improvement acidified soil water-holding compound fertilizer material is fertile and preparation method thereof

Technical field

The present invention relates to slow release fertilizer technical field, particularly relate to a kind of improvement acidified soil water-holding compound fertilizer material fertilizer and preparation method thereof.

Background technology

At present, China market agricultural fertilizer material, substantially there are three kinds: a kind of fertile for industrial chemicals, one is fertilizer, also having one is industrial chemicals and organic fertilizer mixing fertilizer；The shortcoming of industrial chemicals: life-time service can cause soil soil property to harden, and affects plant growth, causes the progressively underproduction；The shortcoming of organic fertilizer is: needed for plant, nutrient is not enough, can not meet the demand of production estimation；Affect crop yield；The shortcoming that mixing is fertile: organic matter and full nutrient in fertilizer formula are conflicting, this is high, and that are low, such as organic too high levels, produce granule difficulty.Additionally; China's Arid&semi-arid area gross area accounts for the 50% of territory total area; China's agricultural is again to use water rich and influential family; Water Consumption in Agriculture exceedes the 70% of total water consumption; and production efficiency is the lowest; China's annual agricultural water breach is about at 30,000,000,000 m 3, and agricultural water crisis presents and constantly aggravates situation.Water-loss reducer of soil is used alone not only increases work number of times and cost, and because water-loss reducer of soil consumption is the most less, it is difficult to be fully contacted with fertilizer so that received moisture is difficult to and nutritional labeling generation reciprocal action, largely reduces effect of water-retaining agent.Additionally, the common fertilizer water solublity used at present is the highest, rate of release is very fast, and the release phase is shorter, and uses totally basal dressing techniques more, make fertilizer nutrient rate of release poor with crop regulation of fertilizer requirement synchronicity, fertilizer nutrient loss is very big, and fertilizer nutrient utilization is relatively low, though and split application method can improve crop different growing nutrient demand, but time-consuming, it is not suitable with the requirement of modern agriculture high-efficient development.And, the fertilizer efficiency height in being manured into soil is in close relations with soil water regime, and " with fertile water transfer, promoting fertilizer with water " is highly important rich water control technique in agricultural production.

Mulch film has the effects such as insulation, water conservation, frost protection to crop, the application of ground membrane technology improves and yield and the benefit adding crops greatly, but tradition mulch film is the macromolecular compound of a kind of synthetic, degradable the most hardly, after using, place to go is not comprehended soil environment is caused the biggest pollution, affects crop root growth, and the mulch film processed is because of moist, damaged, the most not reusable edible, only as garbage reclamation, work consuming is time-consuming.

Therefore, being modified fertilizer, improving fertilizer efficiency is to reduce fertilizer use, the effective way increased operation rate.Slow-release or control-release fertilizer is exactly one of effective measures improving chemical fertilizer utilization ratio such as at present, slow-release or control-release fertilizer can efficiently control the release of nutrient, extend fertilizer efficiency period, meets utilization rate that the whole period of duration of crop to the needs of fertilizer nutrient, can improve fertilizer to greatest extent, reduces the wasting of resources and environmental pollution, to promoting agriculture and forestry volume increase, increasing peasant income, agriculture and forestry sustainable development important role, it it is the important development direction of 21 century fertilizer industry.

Summary of the invention

The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of improvement acidified soil water-holding compound fertilizer material is fertile and preparation method thereof.

The present invention is achieved by the following technical solutions:

A kind of improvement acidified soil water-holding compound fertilizer material, it is prepared by the raw materials in: carbamide 20-23, EM microbial inoculum 3-4, biogas residue 20-22, Bombyx mori L. 6-8, brown coal 8-10, sodium humate 18-22, potassium dihydrogen phosphate 12-15, chitosan 12-13, scarp 8-10, Camellia sinensis waste residue 20-30, antibiotics 1-2, bentonite 6-8, boron mud 4-6, blast-furnace cinder 6-8, polylactic acid 6-9, pentalyn 8-12, N,N methylene bis acrylamide 0.5-1, water are appropriate.

The preparation method of described improvement acidified soil water-holding compound fertilizer material, comprises the following steps:

(1), brown coal, biogas residue are dried and be ground to the mixing of 150-200 mesh, the 1.5-2 times of water taking mixed-powder weight adds in reactor, add mixed-powder and appropriate potassium permanganate is formulated as 4-8% potassium permanganate solution, stirring oxidation 40-60 minute, is heated to 90-100 DEG C, adds the potassium hydroxide of solution weight part 0.2-0.5%, stir 25-40 minute at 2000-2200rpm high speed machine, centrifugation, it is 50-60% that filtrate is concentrated into moisture content, and filtering residue is stand-by；

(2), by step (1) concentrated solution and pentalyn, N, N-methylene-bisacrylamide mix and blend, react 20-30 minute at being heated with stirring to 40-50 DEG C, by carbamide, antibiotics mixed grinding to 60-80 mesh, add suitable quantity of water stirring and melt, with reactant liquor mix and blend, join in drying oven, drying 1-2 hour at 80-88 DEG C, cooling crush crosses 200 mesh sieves, standby；

(3), filtering residue, bentonite, blast-furnace cinder mixed grinding are crossed 200 mesh sieves, put into 1-2 hour processed of stirring leaching in the citric acid solution of 0.1-0.2mol/L, standing removes liquid, oven drying at low temperature, bakes 40-60 minute at 350-400 DEG C, and discharging spray profit steam extinguishes cooling to powder body, add 3-5 times of water stirring to suspended shape, adding polylactic acid, high pressure homogenize stirs, and obtains coating liquid；

(4), sodium humate, boron mud, potassium dihydrogen phosphate are mixed, and add the water mixing and stirring of gross weight 3-4 times, obtain nutritional solution；

(5), by Bombyx mori L., scarp, Camellia sinensis waste residue co-grinding, add after the water of nutritional solution, EM microbial inoculum and gross weight 0.3-0.5 times stirs afterwards, fermentation 30-40 days of banking up at 32-38 DEG C, stand-by；

(6), fermentation material is crushed to 80-100 mesh; add chitosan mix and blend; adjustment moisture is gross weight 42-45%; the ball-type fertiliser granulates of granulator granulation diameter 1-1.2mm; that places band high-pressure nozzle and air cooking rolls on fluid bed at high temperature; coating liquid step (3) obtained repeats to be sprayed at ball-type fertiliser granulates uniformly 3-5 time by high-pressure nozzle; send into tumbling disk granulator; it is simultaneously introduced step (2) and bakes powder; after granulating and forming; within dry 8-10 hour, cool down at 48-50 DEG C, packed and get final product.

The invention have the advantage that

(1) present invention improves the acidified soil water-holding compound fertilizer material interpolation composition such as boron mud, bentonite, improves alkaline components, simultaneously isolation buffer acid-base value, regulates soil acid-base equilibrium such that it is able to effectively improve acidified soil, increase soil fertility.

(2) present invention improves acidified soil water-holding compound fertilizer material and is also added with conventional bacterial manure and inorganic fertilizer works in coordination with microbial activity composition, use multilayer coating structure release structures, external sheath liquid-state mulch film functional component, not only there is the sustained release performance of nutrition release, serve again water retention, can be that soil provides carbon after degraded, the multiple resources such as nitrogen, stimulate growth and development of plants simultaneously, increase the resistance of crop, improve effect of the nutriture of plant, collaborative internal layer bioactive ingredients, improve Soil structure further, give full play to fertilizer efficiency, promote plant growing, improve crop yield.
