Description

A kind of fertilizer additive improveing acidified soil

Technical field

The present invention relates to fertilizer additive field, is exactly a kind of fertilizer additive improveing acidified soil.

Background technology

Soil acidification (showing as the decline of soil pH value) can accelerate the elements such as nutrient element loss, soil compaction, promotion aluminium, manganese and heavy metal activation, change microbial populations in soil and activity, affect crop root and grow and nutrition absorption, grow plant pest etc., thus serious potential threat is formed to agriculture production, ecotope and human health, producing long-range impact to grain security and environmental safety, is the significant problem of the field extensive concerns such as soil science, ecology and environmental science.

Along with population increases and cultivated land area, and the raising of people's living standard, require that agricultural constantly increases product

Measure and improve the quality of products, fertilizer occupies critical role in agriculture production.The fertilizer efficiency period that slow release fertilizer can extend fertilizer is of great benefit to agricultural, can reach single fertilization, exempts operation of topdressing, volume increase, joint fertilizer, saving of labor; And increase operation rate, not only to agricultural, particularly all very great to whole national economy meaning.

Existing slow release fertilizer has three types: one is bag quilt, coating, coating class; Two is urea formaldehyde, IBDU, Oxamides; Three is add various inhibitor fertilizer.。

Current existing interpolation inhibitor slow-release fertilizer is mostly add single inhibitor product, if the patent No. is the patent of invention of 90105012.1 long-acting ammonium bicarbonates and preparation method thereof.

The process of phosphate fertilizer in soil is different from nitrogenous fertilizer, and nitrogenous fertilizer mainly decomposes too fast, and crop has little time absorb and volatilize, leaching loss; Phosphate fertilizer is easy to by soil fixing, makes crop be difficult to absorb, and needs phosphorus element activator to improve P use efficiency for this reason.

Existing fertilizer additive is meeting frowziness when fermenting, and has growing of mosquitos and flies simultaneously, is unfavorable for producing.

Summary of the invention

The object of the present invention is to provide a kind of fertilizer additive improveing acidified soil.

Above-mentioned purpose is realized by following scheme:

A kind of fertilizer additive improveing acidified soil, it is obtained by the raw material of following weight parts: montmorillonite powder 3-5, plant ash 1-2, peat soil 1-3, mud 3-6, the broken last 5-10 that falls leaves, pomegranate rind 6-15 part, Dyhard RU 100 0.3-0.5, thiocarbamide 0.1-0.2, gac 10-12, pomace 40-45, oyster shell whiting 3-5, silicon calcium powder 3-5, xylogen 1-2, EM microbial inoculum 0.1-0.2, bacillus subtilis microbial agent 0.1-0.2, composite reodorant 2-4;

Rhizome of chuanxiong 2-4, baeckea frutescen 1-3, eucalyptus fruit 1-3, psyllium 2-4, zeolite powder 3-5, straw biomass charcoal 1-3, trisodium phosphate 0.1-0.3, chitosan 1-2, Trisodium Citrate 0.1-0.3, peach gum powder 2-3, zinc chloride 0.3-0.4;

The preparation method of described composite reodorant is:

(1), after rhizome of chuanxiong, baeckea frutescen, eucalyptus fruit, psyllium are dried, rub, cross 100-200 mesh sieve, obtain Chinese medicine powder for subsequent use;

(2), after zeolite powder and straw biomass charcoal mix, ultraviolet irradiation 18-22h, mixes composite material is for subsequent use with Chinese medicine powder, peach gum powder;

(3) after all the other raw materials add suitable quantity of water mixing, be more evenly sprayed on composite material, dry in the shade, to obtain final product.

Described a kind of fertilizer additive improveing acidified soil, preparation method comprises the following steps:

(1) by after Dyhard RU 100, thiocarbamide mixing, add water suitable quantity of water, stirs, and obtains combination solution for subsequent use;

(2) in fermentor tank, inject the boiling water of appropriate about 100 DEG C, fermentor tank is put and leaves standstill 40-50 minute in the cool, put into peat soil, mud, the broken end of fallen leaves, pomegranate rind, pomace, EM microbial inoculum ferment, ferment after 10-12 days, add all the other raw materials again, ferment after 15-20 days, leach fermented liquid, stir, obtain fermentation material for subsequent use;

(3) fermentation material surface sprinkling combination solution, after drying, grinding granulation.

Beneficial effect of the present invention is:

(1) add additive montmorillonite powder of the present invention, plant ash, peat soil add potential of hydrogen, microbe colony and the Soil structure that can improve crop root microenvironment, strengthen crop disease-resistant/anti-adversity ability; The water retention capacity of soil can also be increased simultaneously, increase fertilizer efficiency, effectively improve acid soil; Make the continuable sound development of edatope;

(2) nitrification inhibitor is organically combined by the present invention, makes it produce synergy, plays larger inhibition, then adds phosphorus element activator xylogen and coordinate with all the other raw materials the absorption promoting phosphate fertilizer.Charcoal after nitrification inhibitor, phosphorus element activator and uv irradiation, zeolite powder with the use of, can more effectively be fixed in soil by nitrogen element, not easily run off, the effect of increase nitrification inhibitor, plays better slow releasing function; Add the fermenting process that composting promoter etc. accelerates compost simultaneously, improve the N content of composting production; Add the stink that composite reodorant can reduce fermentation material, avoid growing of mosquitos and flies;

(3) present method passes through uv irradiation, effectively can dredge impurity in charcoal and zeolite powder duct, change the absorption property that its pore structure composition fast and effeciently improves biomass charcoal and zeolite powder, prevent nutrient loss, effective raising plant recovery of nutrient, reach the effect of slowly-releasing, the heavy metal substance in soil can be adsorbed simultaneously, reduce heavy metal content in soil.
