Abstract

The invention discloses alkaline land improving and efficient technical field of fertilizer application, specific field is a kind of fertilizer of salt-soda soil special nutritional equilibrium, its raw material composition and corresponding parts by weight are：54~70 parts of wheat stalk, 39~50 parts of pig manure, 22~34 parts of ammonium sulfate, 15~27 parts of calcium superphosphate, 8~14 parts of potassium sulfate, 15~22 parts of furfural dregs, 2~4 parts of 13~18 parts of ardealite and trace element, although nutrient content is relatively low after wheat stalk charing, but pore structure is more flourishing, with larger specific surface area, therefore it can adsorb and load the nutrient of fertilizer, so as to delay ammonium sulfate, the speed of the release N P and K of calcium superphosphate and potassium sulfate in the soil, the utilization rate of nutrient in fertilizer is improved at the same time, chronic administration is accumulated carbon in soil element, the content of organic matter can be effectively increased, the physicochemical property of soil is improved；With reference to organic fertilizer and trace element, nutrition is more balanced, avoids inorganic salts contamination phenomenon from salt-soda soil is effectively administered at the same time.

Description

A kind of fertilizer of salt-soda soil special nutritional equilibrium

Technical field

The present invention relates to alkaline land improving and efficient technical field of fertilizer application, specific field is equal for a kind of salt-soda soil special nutritional The fertilizer of weighing apparatus.

Background technology

Salt-soda soil, which refers to, contains excessive salt and alkali component in the soil body, including solonchak and alkaline earth and other there occurs to a certain degree The general name of all kinds of soil types of salinization or alkalinization, wherein solonchak refer to containing great amount of soluble salt and make most plants The soil that cannot be grown, alkaline earth refer to that transsexual sodium ion accounts for the percentage of cation exchange capacity more than 20% and pH value is more than 8 Soil, in fact since solonchak is often interspersed with alkaline earth, both are referred to as saline-alkali soil, salt-soda soil harm by custom It is larger, it is mainly manifested in and restricts agricultural production, destroys ecological environment and influence sustainable development；Existing fertilizer dedicated to alkaline land material is Alkaline land soil fertility is improved, nitrogen and phosphorus content is higher, and there are unbalanced nutrition, the single situation of nutrient, such a situation brings one Serial environmental problem, wherein more serious is azotate pollution, the salinization for not only resulting in salt-soda soil further aggravates, and Can make in salt-soda soil that nitrate content is exceeded in crop body, though nitrate toxicity itself is small, enter after human body can produce it is carcinogenic Material nitrite, seriously endangers health.

The content of the invention

It is an object of the invention to provide a kind of fertilizer of salt-soda soil special nutritional equilibrium, to solve in above-mentioned background technology The problem of proposition.

To achieve the above object, the present invention provides a kind of following fertilizer of salt-soda soil special nutritional equilibrium of technical solution, its Raw material form and corresponding parts by weight are：54~70 parts of wheat stalk, 39~50 parts of pig manure, excessively 22~34 parts of ammonium sulfate, phosphorus 2~4 parts of sour 15~27 parts of calcium, 8~14 parts of potassium sulfate, 15~22 parts of furfural dregs, 13~18 parts of ardealite and trace element.

Preferably, the trace element is 5 by mass ratio:2:2:2：1:1 ferrous sulfate, manganese sulfate, zinc sulfate, sulfuric acid Copper, boric acid and molybdic acid composition.

Preferably, a kind of fertilizer of salt-soda soil special nutritional equilibrium, its preparation method are：

1) wheat stalk is put into vertical biomass carbonizing furnace and is carbonized, carbonization temperature is 350~450 DEG C, then Wheat stalk charcoal is sieved using 1~3mm sieves；

2) the wheat stalk charcoal screened out in pig manure and step 1) is subjected to compost using existing high temperature aerobic composting method It is extremely decomposed；

3) by the decomposed mixture prepared in step 2), ammonium sulfate, calcium superphosphate, potassium sulfate, furfural dregs, ardealite and micro- Secondary element is uniformly mixed, and is then poured the mixture into electric disc comminutor and is granulated.

The beneficial effects of the invention are as follows：A kind of fertilizer of salt-soda soil special nutritional equilibrium, although being supported after wheat stalk charing Divide content relatively low, but pore structure is more flourishing, has larger specific surface area, therefore it can adsorb and load supporting for fertilizer Point, so as to delay the speed of the release N P and K of ammonium sulfate, calcium superphosphate and potassium sulfate in the soil, while improve in fertilizer and support The utilization rate divided, chronic administration are accumulated carbon in soil element, can be effectively increased the content of organic matter, organic matter is through microorganism point Solution, P in soil H values can effectively be reduced and promote crumb structure in soil to be formed by generating organic acid and organic colloid, the reason of soil Changing property is improved, wheat stalk charcoal and pig manure co-fermentation, and wheat stalk charcoal can increase microbial activity, quickening ferment into Journey, while the loss that ammonia radical ion reduces available nitrogen is adsorbed, fermented pig manure can improve salt-soda soil fertility without germ；Furfural dregs In contain a large amount of free acids, it is loose porous, sweetening of the soil alkalescence, improve soil water permeability；Ardealite sheet can be neutralized as acidity Alkaline land soil alkalescence, and contain sodium ion in the replaceable alkaline land soil of a large amount of calcium ions in ardealite, so that in soil Exchangeable sodium ion reduces, while forms the stronger calcium colloid of cohesiveness, promotes the formation of soil aggregate structure, avoids soil plate Knot；A kind of fertilizer of salt-soda soil special nutritional equilibrium of the present invention, using wheat stalk charcoal as basic fertilizer, controls the release of N P and K Speed, with reference to organic fertilizer and trace element, nutrition is more balanced, avoids inorganic salts contamination phenomenon from salt-soda soil is effectively controlled at the same time Reason.
