Abstract
The invention discloses a nitrogen-rich carbon-based slow release fertilizer. The nitrogen-rich carbon-based slow release fertilizer is prepared from raw materials in parts by weight as follows: 8-10 parts of attapulgite, 6-9 parts of urea, 24-28 parts of chicken manure and urine, 5-7 parts of humic acid raw powder, 4-6 parts of a modified tapioca starch solution, 4-7 parts of ammonium chloride, 1-2 parts of zinc sulfate, 20-24 parts of biogas broth, 14-16 parts of rice straw and 18-22 parts of wheat bran. According to the carbon-based slow release fertilizer, ammonium chloride, urea and other ingredients with high nitrogen content are added on the basis of chicken manure and urine, biogas broth and other organic materials, and an organic and inorganic raw material mixed matching method is adopted, so that sufficient nitrogen is supplied to crops in each period after use of the fertilizer; meanwhile, after the carbon-based slow release layer enters the soil, the nitrogen fixing capacity of soil can be improved, nitrogen loss is reduced, and nitrogen absorption of the crops is further guaranteed.
Description
Technical field
The present invention relates to a kind of technical field of fertilizers, particularly rich nitrogen charcoal slow-release fertilizer of one and preparation method thereof.
Background technology
Biomass charcoal is that having very high biological chemistry stability, improve significantly after entering soil to the physico-chemical property tool of soil, is a kind of outstanding fertilizer slow release material by the plant biomass indissoluble porous solid material that formed of pyrolysis at low temperatures.But utilize the application of biomass charcoal making slow-release fertilizer little in the market; peasant mostly taking cost into account; be reluctant to use the sustained-controll-release fertiliser that price is higher; therefore charcoal slow-release fertilizer can not get the use of mass-producing; on market, widely used polymer capsule material is mostly nondegradable high molecular polymer simultaneously, and the residual meeting after using damages Soil structure.For this reason, current inventor provides a kind of novel charcoal slow-release fertilizer and preparation method thereof, the rice straw utilizing china natural resources to enrich as the raw materials of biomass charcoal to reduce production cost, according to the principle of Sustainable development in material choice, adopt the organic matter of noresidue, pollution-free, easy degraded, prepare the green charcoal slow-release fertilizer that nutritive ingredient is large, granule strength is high, the fertilizer conservation time is long.

The present invention compensate for the deficiencies in the prior art, provides a kind of rich nitrogen charcoal slow-release fertilizer and preparation method thereof.
Technical scheme of the present invention is as follows:
Fertilizer of the present invention is made up of the raw material of following weight part: attapulgite 8-10, urea 6-9, chicken manure urine 24-28, the former powder 5-7 of humic acids, modified tapioca starch solution 4-6, ammonium chloride 4-7, zinc sulfate 1-2, methane liquid 20-24, rice straw 14-16, bran chaff 18-22;
Described modified tapioca starch solution is made up of the raw material of following weight part: tapioca (flour) 45-55, vitriol oil 2-3, potassium permanganate solution 4-6, sodium hydroxide 3-5, borax 1-2, Sodium Selenite 2-3, Calcium hydrogen carbonate 2-4, water are appropriate, its preparation method is dissolved in by tapioca (flour) to double in the water of its quality, sulphuric acid catalysis is added under continuous stirring, potassium permanganate solution oxidation 50-70 minute is added after 5-10 minute, period constantly stirs, then sodium hydroxide gelatinization 15-25 minute is added, add borax again and be cross-linked 10-20 minute, Sodium Selenite is added after stirring, reaction system is heated to 60 DEG C, chelating 15 minutes also stirs, finally add Calcium hydrogen carbonate, and reaction system is heated to 90 DEG C, chelating 30 minutes, in the solution obtained, add 9 times of water to its quality dilute, cool after stirring, namely tapioca (flour) binding agent is obtained.
The concrete steps of the preparation of described fertilizer are as follows:
(1) making compost in pond by putting into after chicken manure urine, methane liquid, the mixing of bran chaff, adding suitable quantity of water and keeping water content at 40%-50%, making compost 25-28 day;
(2) step one gained is become thoroughly decomposed after jointly pulverizing with urea, ammonium chloride, zinc sulfate after material is dried and mix, be placed in granulating disc and make particle, for subsequent use;
(3) by rice straw continuous pyrolysis 2-3 hour at 550-650 DEG C, biomass charcoal powder is obtained, for subsequent use;
(4) step 3 gained biomass charcoal powder, the former powder of humic acids, attapulgite and 60% modified tapioca starch solution are mixed and stirs; mix with step 2 gained particle again after material is moistening and be placed in cylinder; after 40-50 minute, cylinder is heated to 80-100 DEG C until material rolling; in cylinder, spray residue 40% modified tapioca starch solution simultaneously; after 50-70 minute, gained fertilizer is taken out; cross 20 mesh sieves to preserve, obtain charcoal slow-release fertilizer.
The time delay heating energy of preparation process intermediate roll promotes that granular fertilizer improves surface viscosity in the process of water suction, increases fertiliser granulates slow release layer thickness, improves slow release effect.
Beneficial effect of the present invention:
Charcoal slow-release fertilizer of the present invention with the addition of again the high composition of the nitrogen content such as ammonium chloride, urea on the basis of the organic material such as chicken manure urine, methane liquid, have employed the method for organic-inorganic raw material mix and match simultaneously, supply sufficient in the nitrogen demand of each period to farm crop after Fertilizer application can be ensured, carbon-base slow release layer can improve the nitrogen fixing capacity of soil after entering soil simultaneously, reduce nitrogen loss, ensure the absorption of crop to nitrogen further.
Specific embodiments
Below in conjunction with following embodiment, the present invention is described in further detail:
The raw material taking following weight part (kg) is made: attapulgite 9, urea 8, chicken manure urine 26, the former powder 6 of humic acids, modified tapioca starch solution 5, ammonium chloride 6, zinc sulfate 1, methane liquid 22, rice straw 15, bran chaff 20;
Described modified tapioca starch solution is made up of the raw material of following weight part (kg): tapioca (flour) 50, the vitriol oil 2, potassium permanganate solution 5, sodium hydroxide 4, borax 1, Sodium Selenite 2, Calcium hydrogen carbonate 3, water are appropriate, its preparation method is dissolved in by tapioca (flour) to double in the water of its quality, sulphuric acid catalysis is added under continuous stirring, add potassium permanganate solution after 7 minutes and be oxidized 60 minutes, period constantly stirs, then sodium hydroxide gelatinization is added 20 minutes, add borax more crosslinked 15 minutes, Sodium Selenite is added after stirring, reaction system is heated to 60 DEG C, chelating 15 minutes also stirs, finally add Calcium hydrogen carbonate, and reaction system is heated to 90 DEG C, chelating 30 minutes, in the solution obtained, add 9 times of water to its quality dilute, cool after stirring, namely tapioca (flour) binding agent is obtained.
The concrete steps of the preparation of described fertilizer are as follows:
(1) making compost in pond by putting into after chicken manure urine, methane liquid, the mixing of bran chaff, adding suitable quantity of water and keeping water content 45%, making compost 28;
(2) step one gained is become thoroughly decomposed after jointly pulverizing with urea, ammonium chloride, zinc sulfate after material is dried and mix, be placed in granulating disc and make particle, for subsequent use;
(3) by rice straw continuous pyrolysis 2 hours at 600 DEG C, biomass charcoal powder is obtained, for subsequent use;
