Description
Technical field
The invention belongs to organic fertilizer technical field, particularly relate to a kind of water quality fertilizer and its preparation method and application.
Background technology
China is an inorganic fertilizer big producing country is also that an inorganic fertilizer consumes big country, most nutrition of inorganic fertilizer is by soil absorption, the specific absorption of plant is very low, cause the generation causing nitrate, nitrite to the pollution of soil, soil compaction, obnoxious flavour, soil is seriously destroyed, and therefore the pollution of inorganic fertilizer to soil is urgently administered.
Organic fertilizer is rich in the nutritive substance needed for organic substance and plant growth, can not only provide nutrient needed for plant growth, improvement soil, can also crop quality be improved, improve crop yield, promote high crop yield stable yields, preservation of fertility, can improve utilization rate of fertilizer simultaneously, reduces production cost.Abundant Appropriate application organic fertilizer can increase crop yield, culture fertility, improves quality of agricultural product, improve the validity of soil nutrient.
Application number is that the Chinese patent application of 201110196473.X discloses biological organic fertilizer of a kind of paper mill sludge production and preparation method thereof, described fertilizer adopts paper mill sludge, calcium lime powder, ferrous sulfate, magnesium sulfate, peanut muffin, rice bran powder, useless plant, biological organic fertilizer quick fermentation bacterial classification microbial inoculum, organic matter decomposing inoculant, Methionin, ammonium nitrate, monoammonium phosphate, potassium sulfate, triacontanol price quote, sodium nitrophenolate and organic activator etc., twin shaft paddle mixing and blending machine is adopted to mix, make powder or particle and make paper mill sludge organic fertilizer product through packaging.This product nutritive ingredient is complete, wherein crop growth needs can be supplied containing nitrogen, phosphorus, potassium and the various nutrient such as various trace elements and organic acid, solve paper mill sludge secondary pollution, but this fertilizer organic content is low, preparation method is loaded down with trivial details, the side effect that component too much can cause fertility mutually to restrict.In addition because this fertilizer is solid-state fertilizer, not easily absorb under drought condition.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of water quality fertilizer and its preparation method and application.Described water quality fertilizer organic content is high, does not burn seedling, has improving effect to the barren soil after using chemical fertilizer, reduce rate of fertilizer application year by year, also can keep equal fertility, plant absorption is fast, can solve the technical problem that plant under drought condition not easily absorbs fertilizer nutrient.
Technical scheme of the present invention is as follows: a kind of water quality fertilizer, and described fertilizer is made up of rubber seed oil cake and pulp-paper mill effluents; The mass ratio of described rubber seed oil cake and pulp-paper mill effluents is 30 ~ 50:70 ~ 50.Described rubber seed oil cake is also referred to as rubber seed oil cake, and existing rubber seed oil expression method first steams stir-fry rubber seed, then extracts oil, belong to hot moulding, the oil cake obtained contains the organic matters such as a large amount of protein, and heat is too high, easily burns seedling, the present invention does not steam stir-fry rubber seed, but directly extract oil after rubber seed and water mixing, belong to cold-squeezing, the rubber seed oil cake that the method obtains is manufactured with machine fertilizer, can not seedling be burnt, have governance role to barren soil.
In described water quality fertilizer, organic content is more than 40%, and proportioning different organic matter contents is different, can determine the proportioning of rubber seed oil cake and pulp-paper mill effluents in water quality fertilizer according to plant-growth situation.
The present invention makes full use of the pulp-paper mill effluents in pulp production, turns waste into wealth, environmental protection, trade effluent and rubber seed oil cake are obtained efficient organic fertilizer, organic content, up to more than 40%, does not burn seedling, is applicable to various farm crop and cash crop use.
The present invention also provides the preparation method of described water quality fertilizer.Described preparation method comprises the step preparing rubber seed oil cake, and the step of preparation pulp production slag charge and pulp-paper mill effluents prepare the step of pond sludge;
The preparation process of described rubber seed oil cake is as follows: 8 annual ~ December selects rubber seed then, rubber seed is mixed with water, then obtains rubber seed oil cake by deoiling treatment, then oil cake is carried out scorch dry after stand-by, rubber seed oil cake is dried frangible, is easy to make water quality fertilizer.
The steaming-roasting temperature of described rubber seed oil cake is 90 ~ 120 DEG C; The mass ratio of described rubber seed and water is 18 ~ 22:1.
It is as follows that described pulp-paper mill effluents prepares pond sludge step: peeled by poplar tree, then sloughs a part of resin to the poplar tree cleaning after peeling, and be cut into sheet through decatize degreasing, and gas adds water immediately after steaming degreasing carries out one section of squeezing extrusion and obtain wood pulp material;
Wood pulp material is carried out first paragraph mechanical jordaning, stores for some time after first paragraph mechanical jordaning, enter second segment and beat mill, second segment stores for some time after beating mill, obtains machinery and beats mill paper pulp, filter and obtain pulp-paper mill effluents;
Then be mixed to form water quality fertilizer with pulp-paper mill effluents mass ratio 30 ~ 50:70 ~ 50 after the rubber seed oil cake of preparation being processed into powder, obtained water quality fertilizer does not need fermentation, can directly use.
The poplar tree (latin name is Populusalba) that described method adopts, belongs to northern species broad-leaf forest class, is tamed after breeding and can plant in south, can fast-growing can fell in 5 years after plantation, can regenerate ten times after felling, output is higher, is suitable for for preparing paper pulp.
The poplar tree that the present invention adopts is GKT88 poplar, and GKT88 poplar is on the basis of introducing Taiwan White willow seedling, and breeds in conjunction with local soil, weather, environment and the plant chain domestication in Yunnan; With preventing disease and pest plants interplanting during the plantation of GKT88 poplar, do not spray insecticide, adopt GKT88 poplar to prepare the heavy metals content after paper pulp low, the fertilizer therefore obtained will cause heavy metal contamination, soil compaction barren to soil.
The present invention also provides the described application of water quality fertilizer on agricultural, forestry or cash crop, every mu of consumption of fertilizer determines the demand of fertility according to Different Crop, be 100kg if GKT88 poplar every mu of consumption is First Year, Second Year 90kg, 3rd year 80kg, apply fertilizer 70kg later every year, but can obtain the fertility executing 90kg fertilizer.
Compared with prior art, the present invention has following beneficial effect: the present invention makes full use of the trade effluent in pulp production, turns waste into wealth, environmental protection, obtained efficient organic fertilizer, and organic content is up to more than 40%, does not burn seedling, improving effect is had to the barren soil after using chemical fertilizer, reduce rate of fertilizer application year by year, also can keep equal fertility, be applicable to various farm crop and cash crop use, under drought condition, plant also fully can absorb fertilizer nutrient.
Embodiment
Below in conjunction with specific embodiment, technical scheme of the present invention is described in further details.
