Problems solved by technology

However, there are relatively few studies on the resource utilization of hickory cattail shells
"Comprehensive Treatment of Pollution and Its Effects of Carya Cattail Pollution" (Wang Guoping, Modern Agricultural Science and Technology, 2006) suggested that the pecan cattail shell should be used as alkaline fertilizer, pesticide or fine carbon, but no specific method was proposed
Chinese Patent Publication No. CN101838163A (Effective Method for Thoroughly Cure Environmental Pollution by Bamboo Shoot Shells and Hickory Cattail Shells, Yang Jun), published on September 22, 2010, proposes mixed fermentation of anaerobically fermented rancid bamboo shoot shells and hickory cattail shells, The reduction of hickory cattail shells has been preliminarily realized, but the highest temperature in the entire fermentation process is only 45-55°C, which makes it difficult to kill E. coli and other pathogenic bacteria in the materials
Dong Minghua et al. (a process method for preparing biological fertilizers using hickory cattail shells, Chinese Patent Publication No. CN102674915A) used biological sludge and straw powder to mix hickory cattail shells, and the microorganisms in the sludge made the materials in the range of 33 to 35 Anaerobic fermentation at ℃ for 8-10 days, the product prepared by this method is not completely decomposed, the product quality is difficult to meet the requirements, and the product may burn seedlings

Embodiment 1

[0031] Step ①, material mixing

[0032] Hickory cattail shells are crushed into cattail shell powder with a particle size of 1.3mm to 1.5mm, and the cattail shell powder, cake and superphosphate are mixed evenly in a weight ratio of 55:41:4, and the pH of the mixture is 6.0 to 6.5 , and add an appropriate amount of water to adjust the moisture content of the mixture to 65%; the cake is selected from peanut cake.

[0033] Step ②, aerobic fermentation

[0034] The mixture and microbial agent I are piled up (stacks with a height of 1m and a width of 2m). After fermentation for 2 to 3 days, when the temperature of the pile rises to 60-70°C, use a turning machine to turn the pile. When the temperature of the pile drops The aerobic fermentation ends at 30-40°C, and the aerobic fermentation time is 9-12 days.

[0035] The weight of the microbial agent I is 0.5% of the mixture (including the added water, the same below), and the colony-forming unit ratio of Aspergillus niger, Sporos...

Abstract

The invention relates to an organic fertilizer and a production method thereof, and particularly relates to a method for producing an organic fertilizer by utilizing hickory hulls. The method comprises the following steps of: uniformly mixing hull powder, meal and superphosphate, inoculating the obtained mixture into a microbial inoculan I after moisture is adjusted, and carrying out aerobic fermentation under the turning condition; after fermentation, inoculating a microbial inoculan II into the material, and then carrying out piled aging, drying, crushing, sieving and packaging and the like to obtain a hickory hull organic fertilizer. Aiming at the characteristics that lignin in the hull has a high content, and is difficult to break down, trametes gallic which has strong adaptability and is capable of breaking down lignin and cellulose is added during the piled aging, paint enzymes and lignin peroxidases generated in the growth process of the trametes gallic can promote conversion of lignin to humic acid, and simultaneously, lignin wrapped cellulose is released; and after the cellulose is treated at high temperature in the aerobic fermentation process, the cellulose is changed in structure, so that the cellulose is easily utilized by microbes, the material is composted more thoroughly, and the content of humic acid in the product is increased.

Description

technical field [0001] The invention relates to an organic fertilizer and a production method thereof, in particular to a method for producing organic fertilizer by using hickory cattail shells. Background technique [0002] Hickory cattail shell is the exocarp of hickory nut, which has high lignin content, and only a few fungi can degrade lignin. Hickory cattail shells are alkaline and contain a variety of alkaloids, flavonoids, tannins and other substances. It is difficult for many microorganisms in nature to survive in them. Therefore, hickory cattail shells are difficult to degrade and rot in the environment. In the hickory processing place, there will be catkin shells about 5 times the volume of the hickory stone fruit. The accumulation of a large number of pecan shells will seriously affect the ecological environment of the hickory producing area. [0003] The research on hickory cattail shells mostly focuses on the active substances in it, such as alkaloids, pigments...
