Description
Technical field
The present invention relates to technical field of fertilizers, more particularly to a kind of saline and alkaline tibet milkwort root Special slow release fertilizer and preparation method thereof.
Background technology
The soil salinization is very serious at present, brings prodigious influence to agricultural, is unfavorable for the plantation of plant.Due to salt marsh
The physics and chemistry function of changing soil is poor, causes the microbial activity in soil very low, and plant can not normally grow, therefore gives agriculture
Industry resource brings adverse effect.China's salinization soil area accounts for about territory total area there are about more than 20 ten thousand square kilometres
2.1%.In the arable land in 100,000,000 square kilometres of China, there are about 10% soils to belong to salinization soil, in addition, also more than 2000
The salt wasteland of hectare, wherein most are not opened up wasteland and are utilized.These salinization soils how are opened up wasteland and utilized, growing surface is expanded
Product increases national income, is one of the major issue in current agricultural production.National government and scientific researcher are all paid attention at present
Reparation to salinization soil actively develops the research of various aspects and rational utilization, makes effectively soil money
Source, peanut is one of legume, major oil crops, and in oil crops, the oil yield of peanut is up to 45%~50%, far
Higher than other oil crops, the relative amount of oleic acid is up to 50% or more in peanut, and human body cardiovascular benefic can drop in oleic acid
Low blood fat and cholesterol, China are one of maximum peanut countries of consumption in the world, however peanut be suitable in Acid soil it is raw
Long, fertilizer special for peanuts on the market is also suitble to use in Acid soil mostly at present, to increase the cultivated area of peanut,
It needs to develop a kind of fertilizer specially for peanut for being suitable for using in salt-soda soil.
Invention content
To overcome the defect of the above-mentioned prior art, a kind of saline and alkaline tibet milkwort root Special slow release fertilizer of present invention offer and its preparation side
Method.
It is achieved particular by following technical scheme：.
A kind of saline and alkaline tibet milkwort root Special slow release fertilizer, organizing sub-category and corresponding parts by weight is:Phosphoric acid material pulp 18~24

0.4 part.
Preferably, a kind of saline and alkaline tibet milkwort root Special slow release fertilizer, organizing sub-category and corresponding parts by weight is:Phosphorus
22 parts of sour slurry, 9 parts of Diammonium phosphate (DAP), 13 parts of potassium carbonate, 8 parts of sodium nitrate, 8 parts of potassium chloride, 8 parts of sulphur, 6 parts of boric acid, fulvic acid 23
Part, natural crystal fertilizer 6,13 parts of green manure, 1 part of biological bacteria powder, 0.4 part of surfactant.
Further, the sulphur is the sulphur powder of granularity≤100um.
Further, the natural crystal fertilizer is one or more in potassium feldspar, celestine, zeolite.
Further, the green manure is 3 by mass ratio:1:5 hybrid giant napier, green alga, clover composition.
Further, the biological bacteria powder is 5 by mass ratio:3:1 lactic acid bacteria, bacillus subtilis and photosynthetic bacteria is mixed
It closes.
Further, the surfactant is neopelex.
A kind of saline and alkaline tibet milkwort root Special slow release fertilizer of the present invention, preparation method include the following steps：
1) green manure is crushed to the powder for being granularity≤2mm, the clear water of 3~5 times of powder and its quality is mixed, immersion 3h,
Biological bacteria powder is added, is preserved two days at 35~39 DEG C, natural crystal fertilizer is added and is uniformly mixed, room temperature is dried under reduced pressure to water content
It is 20~30%, granulation；
2) surfactant is previously added in phosphoric acid material pulp, then slurry is passed through in tubular reactor, be heated to 130
~160 DEG C, sulphur is added and is uniformly mixed；
3) mixture, Diammonium phosphate (DAP), potassium carbonate, sodium nitrate, potassium chloride, boric acid, the fulvic acid obtained by step 2) are launched
It being mixed at room temperature in horizontal mixer, the mixing time is 15~20min, and rotating speed is 12~18r/min,
Particle stirring 5-10min obtained by step 1) is added to be granulated, is dry, sieving.
Beneficial effects of the present invention：
The saline and alkaline tibet milkwort root Special slow release fertilizer of the present invention passes through being used cooperatively for natural crystal fertilizer, green manure and each fertilizer efficiency element
It realizes the control that is discharged to fertilizer, the loss of fertilizer nutrient can be effectively reduced, improve the utilization rate of fertilizer nutrient, and can be with
Reduce the labour needed for top dressing, at the same can reduce nutrient it is heavy remaining caused by environmental pollution, sulphur is in subacidity, to salt-soda soil
There is certain improved effect, reduces salt-soda soil pH value；It will produce more acid ion after being applied in soil, and it provided for peanut
The boron element provided described in the larger microelements of calcium of demand, boric acid can promote peanut to provide the absorption of calcium for soil
More organic matters promote the root system development of peanut, are effectively improved alkaline land soil structure, the phosphorus potassium of indissoluble in activated absorption soil
Compound improves the gas permeability of soil, while Peanut Root System can be stimulated to grow, and reduces the generation of pest and disease damage in peanut cultivation.
