Embodiment 1

[0040] As shown in the figure, a straw ecological compound fertilizer intelligent preparation system includes a cutting unit, a fermentation unit, an intelligent control unit, a waste heat recovery unit, a filter press unit, a grinding and crushing unit, a mixing unit, a granulation and drying unit and a finished product classification unit. The fermentation unit includes a fermentation tank 1, a biogas recovery mechanism 2, a heating mechanism 3, a heat exchange mechanism 4, a spray mechanism 5, an automatic feeding mechanism 6, a stirring mechanism 7 and an intelligent temperature control unit. The intelligent temperature control unit includes a temperature The sensor 8 and the intelligent control chip, the fermenter has a cavity for straw fermentation, the temperature sensor 8 and the stirring mechanism 7 are set in the cavity, wherein there are multiple temperature sensors 8, which can be distributed on the inner wall of the cavity and the stirring mechanism , the intellige...

Embodiment 2

[0047] A method for preparing high-efficiency ecological fertilizer by microbial fermentation of straw, using biological straw as the main raw material and animal manure as the starter, the specific preparation method is as follows:

[0048] S1. Cut the waste biological straw into straw sections with a length of 5-10cm, and load it into the fermenter from the feeding port on the top of the fermenter with an automatic feeding mechanism, and then use 10 times of the fresh animal manure according to the ratio of 2% of the straw weight After dilution and stirring with water, it is sprayed onto the straw in the tank through the spraying mechanism, and the stirring mechanism is started to mix the feces liquid and the straw evenly; when initially feeding, use the heating mechanism to rapidly raise the temperature in the tank to above 30°C, and then carry out closed natural fermentation , the fermentation period is 3-5 days; during the fermentation period, the temperature in the tank i...

Embodiment 3

[0056] A method for preparing quick-acting slow-release integrated high-efficiency ecological fertilizer by using straw microbial fermentation, the steps are the same as in Example 2, the difference is that step S4 is: add 25-30% clay dry powder to the straw powder obtained by grinding step S3 according to its weight , 15-20% inorganic fertilizer, mixed and stirred evenly, granulated by a granulator, ventilated, dried and dried to obtain an ecological compound fertilizer. Inorganic fertilizer is any one or more combinations of N fertilizer, P fertilizer, potassium fertilizer or other inorganic fertilizers acceptable to crops, and its combination ratio can also be reasonably adjusted according to the different soil properties in the area where the fertilizer is used.

Abstract

The invention discloses an intelligent preparation system and preparation method for synthesizing a quick-acting and slow-release integrated efficient ecological compound fertilizer through straw microbial fermentation. The system comprises a cutting unit, a fermentation unit, an intelligent control unit, a waste heat recovery unit, a press filtration unit, a grinding and crushing unit, a blending unit, a granulation and drying unit and a finished product sub-packaging unit, wherein the fermentation unit comprises a fermentation tank, a biogas recovery mechanism, a heating mechanism, a heat exchange mechanism, a sprinkling mechanism, an automatic feeding mechanism and a stirring mechanism. The method comprises the following steps: performing sealed fermentation on straws and animal feces; and performing water press filtration on a fermentation product, then performing high-temperature inactivation, adding an appropriate amount of inorganic quick-acting fertilizer and trace element fertilizer, rooting powder, a drought-resistant water retention agent and clay, mixing, and performing granulation and drying to obtain the compound fertilizer. By adopting the system and the method disclosed by the invention, fresh animal feces are used as a leaven which contains a lot of microorganism bacteria and digestive enzymes and can promote biological degradation and decomposition of the straws; and moreover, the animal feces are further fermented to be beneficial for opening unstable ester bonds in straw cellulose, accelerating the degradation of the straws and shortening the fermentation period.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation of agricultural straw resources, and specifically relates to an intelligent preparation system and a preparation method for synthesizing quick-acting slow-release integrated high-efficiency ecological compound fertilizer by using straw microbial fermentation. Background technique [0002] 1. Straw burning is not only a waste of resources, but also extremely harmful. [0003] Hazard 1: pollute the air environment and endanger human health. Data show that when straw is burned, the three pollution indexes of sulfur dioxide, nitrogen dioxide and inhalable particulate matter in the atmosphere reach their peaks, among which the concentration of sulfur dioxide is twice as high as usual, and the concentration of nitrogen dioxide and inhalable particulate matter is higher than usual 3 times, which is equivalent to the fifth level of the daily average concentration. When the concentration ...
