Embodiment 1

[0028] Take 60 parts of dehydrated bamboo shoot shells and 40 parts of fermented cow dung; adjust the water content to 65%, mix evenly, and place in a fermentation tank. After the temperature rises to about 60°C, it must be turned once a day, and twice in the morning and evening when the temperature is high. After 15-25 days of fermentation, it is naturally dried to a moisture content of 10-20%, crushed, and packaged to become a finished product of bamboo shoot organic fertilizer. The bamboo shoot shell organic fertilizer is used as a base fertilizer and applied to the broccoli field in the organic vegetable demonstration area, which can significantly improve the soil structure, promote the nutrient absorption of the broccoli, improve the disease resistance and fruit quality of the broccoli, and increase the yield by 10-15% per mu.

Embodiment 2

[0030] Take 70 parts of dehydrated bamboo shoot shells and 30 parts of fermented sheep manure; adjust the water content to 60%, stack and ferment for 15-20 days, dry to about 10% water content, crush, and granulate with an extrusion granulator to form bamboo shoots The shell organic fertilizer is a finished product, and the moisture content of the granulated organic fertilizer is controlled within 5%. Applying the bamboo shoot organic fertilizer to the organic tea garden can significantly improve the soil structure, improve the organic carbon content of the tea garden soil, and promote the germination of morning tea.

Abstract

The invention relates to technology for producing an organic fertilizer by using bamboo shoot hulls serving as raw materials through mixed compositing fermentation. The technology comprises the steps of: cutting and crushing the bamboo shoot hulls, performing screw extrusion dehydration on the bamboo shoot hulls, adding fermented ruminant manures into the bamboo shoot hulls, mixing the materials uniformly, and delivering the materials in a trench type fermenter for compositing fermentation; when the temperature of the materials rises to between 60 and 70 DEG C, performing stack-turning on thematerials for oxygen supply by using stack-turning equipment, and further dehydrating the materials; in a high-temperature period, performing the stack-turning at least once each day, and after acid content of the extruded juice is adjusted, returning the juice to the composting uniformly; and after the fertilization is completed, according to different purposes, packing the composting directly or packing crushed composting to obtain the organic fertilizer, or performing extrusion granulation on the composting to obtain the organic fertilizer. The technology is simple and feasible, can realize the resource utilization of the waste bamboo shoot hulls, does not generate secondary pollution, and provides a safe and pollution-free fertilizer for agricultural production while solving the pollution problem.

Description

technical field [0001] The invention belongs to the field of comprehensive pollution control and waste recycling in the environmental field, and relates to a process for preparing a new type of organic fertilizer by using waste bamboo shoot shell resources through microbial fermentation. Background technique [0002] At present, various agricultural product processing wastes have become the enemy of the environment. However, bamboo shoot shells, as a special form of renewable agricultural resources, have great mining potential. Fresh bamboo shoot processing is a characteristic industry in more than 10 provinces (regions) in the Yangtze River Basin and south of it, such as Sichuan, Fujian, and Zhejiang. There is also a large amount of bamboo shoot shell processing waste discarded, piled up, and rotten. CN1793068A "Production process for converting waste bamboo shoot shells into organic fertilizer" and CN1887822 "Bamboo shoot shell organic-inorganic compound fertilizer and i...
