Abstract
The invention discloses a method for producing an organic granular composite fertilizer by using crop straws, belonging to production methods of agriculture granular fertilizers. The method comprises the following steps: crushing crop straws, sequentially putting the crushed crop straws and animal manure into a biogas digester for fermentation, fermenting to obtain biogas slurry and biogas residues, pouring the biogas slurry on the crushed crop straws and the biogas residues, stirring and performing stack retting for natural fermentation, turning over when the fermentation temperature is up to 40-70 DEG C, uniformly mixing and stirring 40wt% of composted fertilizer, 20wt% of urea, 15wt% of potassium chloride and 25wt% of superphosphate, and pelleting by using a spiral extruder. The method is simple in process and low in cost and can take effect quickly, about 70% of the equipment investment can be saved, and a novel way is developed for increasing the grain yield and prompting virtuous cycle of the agriculture biological environment.
Description
technical field:
The present invention relates to a kind of agricultural fertilizer, particularly a kind of method of the organic granular compound fertilizer utilizing crops stalk and animal excrement to produce.
background technology:
China is at present in rural area, and agricultural crop straw great majority are all burnt, and does energy heating, cooks.Even crops straw returning field, because some stalk this season can not rot, during lower season sowing, the meeting of rotting is not had to have influence on seed germination.Although some area utilizes stalk to manufacture natural pond slag, utilize the fertile ground of natural pond slag, because natural pond slag is shapeless, use very inconvenient, and contained nitrogen, phosphorus, potassium are very low.
summary of the invention:
The object of the invention is to the deficiency solving the existence of above-mentioned technology, the efficiency of thorough solution crops straw returning field, change the backwards processing mode of directly burning in rural area, simultaneously solution rural area animal excrement pollution on the environment and provide a kind of with the method for producing organic granular compound fertilizer from crop stalks.
The present invention realizes with following technical scheme: comprising with agricultural crop straw is base-material, by crops stalk crushing, and the agricultural crop straw after pulverizing is made organic granular compound fertilizer through the operation of following order and formula successively: pulverizing agricultural crop straw and animal excrement are put into civil methane pond and are carried out spontaneous fermentation by (1), natural pond slag and natural pond liquid is formed after fermentation, water with natural pond liquid and mix broken agricultural crop straw and natural pond slag carries out stack retting spontaneous fermentation, stir up and down when the temperature of fermenting reaches 40 ~ 70 DEG C; (2) when fermentation is down to less than 25 DEG C, water content is down to 15 ~ 25%, pH value for 6 ~ 7 time formed become thoroughly decomposed fertile in % weighing scale, will become thoroughly decomposed fertilizer 40%, and urea 20% Repone K 15%, calcium superphosphate 25% mixing and stirring, uses extruser grain forming.
The present invention is adopted to have following beneficial effect:
1, present invention process is simple, cost is low, instant effect, profitable, with regard to extruser shaping particles one, just can save facility investment about 70%, and improve grain yield, therefore, this invention has higher popularization practical value.
2, the present invention is that base-material produces biogas, natural pond slag and natural pond liquid with agricultural crop straw, water with natural pond liquid again and mix broken agricultural crop straw and natural pond slag, make agricultural crop straw fast rotting, agricultural crop straw is in fermenting twice process, thorough fermentation maturity, can fully dissolve in being manured into soil, farm crop can fully absorb, and improve the output of farm crop.
3, this invention changes the behindhand type that stalk is directly burnt in rural area, promotes the benign cycle of ecotope of agricultural, opens and has kept away a new approach.
Embodiment is as follows:
The present invention take agricultural crop straw as base-material, first farm crop is ground into 150 orders, then the agricultural crop straw of pulverizing is made organic granular compound fertilizer through following processing step successively; (1) by % weighing scale, the agricultural crop straw 35% of pulverizing and animal excrement 65% are stirred stacking process, methane-generating pit fermentation is put into when temperature reaches 40 DEG C, methane-generating pit leavening temperature is 40 DEG C, pH value is 7, natural pond liquid and natural pond slag can be gone out successively through 30 days, water with natural pond liquid and mix broken agricultural crop straw and natural pond slag carries out stack retting spontaneous fermentation; (2) stir when leavening temperature reaches about 50 DEG C, when fermentation is down to less than 25 DEG C, water content is down to less than 15%, the fertilizer formed when pH value is 7 becomes thoroughly decomposed fertilizer, and by % weighing scale, will become thoroughly decomposed fertilizer 40%, urea 20% Repone K 15%, calcium superphosphate 25% mixing and stirring, uses extruser grain forming, packaging warehouse-in.
Claims (1)
1. one kind with the method for producing organic granular compound fertilizer from crop stalks, comprise with agricultural crop straw is base-material, farm crop are pulverized, it is characterized in that: by the agricultural crop straw after pulverizing successively through processing step below: methane-generating pit spontaneous fermentation is put in (1) broken agricultural crop straw and animal excrement, form natural pond liquid and natural pond slag after fermentation, water with natural pond liquid and mix broken agricultural crop straw and natural pond slag carries out stack retting spontaneous fermentation; Stir up and down when the temperature of fermenting reaches 40 ~ 70 DEG C; (2) when fermentation is down to less than 25 DEG C, water content is down to 15 ~ 25%, pH value for 6 ~ 7 time the fertilizer that becomes thoroughly decomposed that formed, by % weighing scale, fertile 40% will be become thoroughly decomposed, urea 20% Repone K 15%, calcium superphosphate 25% mixing and stirring, makes organic granular compound fertilizer by extruser shaping particles.
