Abstract

The said fertilizer is black powder prepared with gangue and middlings as basic material as well as several chemical material including phosphorus trichlorid, acetone, ethylenediamine acid, potassium sulfate, zinc powder, etc. and through crushing, mixing and sieving. It is used as base fertilizer and can improve soil, raise moisture-keeping capacity of soil, regulate soil quality and produce lasting fertilizer effect. When used in conjunction with other chemical fertilizers, it can produce ever high yield-increasing effect.

Description

The preparation method of humic acid organic fertilizer

The present invention relates to a kind of fertilizer of crops, specifically is the preparation method of humic acid organic fertilizer.

Humic acids is a kind of mixture of amorphous macromolecule compound of complexity, has certain adsorptivity, is available as fertilizer of crops, can promote plant-growth, improves the output of farm crop, also can make soil improvement agent, plant-growth regulator etc.The preparation method of relevant humic acids and that humic acids is used for the record of mixed fertilizer is more exists generally that raw material sources are few, price is expensive or complex process, equipment reach poor yields, problem that fertility is low more.Some new preparation methods have been reported in recent years, exist some weak point equally, as CN87101113 disclose with in the organic sludge with addition of additive, after finishing technologies such as bio-transformation and ammonification processing under the specific aerobic conditions of biochemical groove, realize, the problem that this method exists is that the organic sludge composition changes greatly, and corresponding additive capacity also changes thereupon, and the specific aerobic conditions of biochemical groove is anti-to grasp simultaneously, processing condition often become, and yield is low; CN88107216 introduces the method for producing humic acids with furfural dregs, comes amount to limit because of being subjected to raw material, can't produce in enormous quantities; Through explained hereafter humic acidss such as acidifyings, its raw material and processing condition are restricted by its factor with papermaking wastewater in the production method introduction of CN92106049 humic acid liquid compound fertilizer; C93102447 discloses brown coal and made humic acid fertilizer through microbial process, and is that bacterium in this method and fungi are difficult for getting and to make the humic acids component content low etc.

The object of the present invention is to provide a kind of component content height, fertility length, abundant raw material, technology is simple, equipment is few, cost is low, the humic acid organic fertilizer preparation method of easy enforcement.

Technical scheme of the present invention is: with coal drystone, middle coal is that basic raw material cooperates partly inorganic and Organic Chemicals to make, and (1) its component and proportioning (weight ratio) are: coal drystone 42-46 part, middle coal 34-38 part, phosphorus trichloride 2.5-2.9 part, acetone 1.3-1.5 part, quadrol acid 0.7-0.9 part, vitriolate of tartar 6.2-6.8 part, zinc powder 1.5-1.9 part, potassium permanganate 0.6-0.8 part, phenol 3.2-3.8 part, nitric acid 1.4-1.6 part and boric acid 1.1-1.3 part; (2) its working method is: coal drystone and middle coal carry out just broken, granularity is 1.5-2.0cm, being conveyed into the density pulverizer more further pulverizes, granularity is below the 0.2mm, weigh after travelling belt is sent in the mixing tank, above-mentioned industrial chemicals is poured in the mixing tank one by one into mixing and stirring by proportioning, cross 20 mesh sieves, promptly get 10-20 order powdered finished product.

In the above-mentioned raw materials, coal drystone and the main content of middle carbon are carbon, also contain natural sulphur in its coal drystone and play sterilization and promote soil improvement action; Containing various trace elements such as calcium, magnesium, nitrogen, phosphorus, potassium, sulphur in the middle coal, is the nutritive element of farm crop; Phosphorus trichloride and vitriolate of tartar strengthen phosphorous, the potassium amount of soil property; Potassium permanganate plays the various disease and insect effects in the soil of eliminating; Boric acid, phenol and quadrol acid form multicomponent complex with trace element, have well water-soluble and shock absorption, cooperate various nutrient elements, can satisfy, regulate and stimulate crop growth, increase fertilizer efficiency; Nitric acid can reduce the hardness of base-material; Acetone is regulated the variation of soil structure; Zinc promotes plant absorbing sunlight and regulates soil physical and chemical property.

Above-mentioned industrial chemicals is article commonly used, and chemical industry shop, various places is all on sale.

The humic acid organic fertilizer material that contains multiple element provided by the invention is one of indispensable base fertilizer in the soil, can improve the soil, improve water retention capacity, the adjusting soil property changes, and its fertility reached in soil more than 18 months, and to be used effect better with other chemical fertilizer.Its technology is simple, abundant raw material, cost are low, implements easily.
