Embodiment 1

[0049] A method of utilizing apple tree pruning and eliminating fruit trees to produce bio-organic fertilizer, comprising the following processes:

[0050] Step 1, raw material pretreatment: crush the collected branches, screen the sawdust units with a length between 20 and 60mm as raw materials, and send them to the hydrothermal pretreatment reactor through the conveyor belt for hydrothermal steam pretreatment, pretreatment The specific process is as follows: Weigh 1000g of crushed raw materials, mix them evenly with water under the condition that the mass ratio of solid to liquid (sawdust and water) is 1:2, and keep the temperature in the hydrothermal system at 140°C for 30 minutes, and maintain the system pressure at 4Mpa during the reaction process. After the pretreatment, stop heating, open the main reaction tank, let the substrate enter the buffer tank and cool down for 4 hours, then collect the raw materials for the next step of fermentation;

[0051] Step 2, the prepar...

Abstract

The invention discloses a method for producing biological organic fertilizer by utilizing a pruned branch and an obsolete fruit tree of an apple tree. The method particularly comprises the following steps of a step 1, pretreatment of raw materials: crushing the apple tree and the pruned branch thereof into sawdust units, screening a sawdust raw material with the length of 20mm to 60mm, carrying out high-temperature and high-pressure steam pretreatment on the sawdust raw material, and naturally drying for 4h to 6h after the treatment is completed; a step 2, preparing a fermentation microorganism mixed microbial inoculum; a step 3, carrying out composting fermentation on the raw material subjected to the pretreatment in the step 1; a step 4, repeatedly pile-turning fertilizer fermented in the step 3, and carrying out the composting fermentation again; a step 5, packaging and storing the fertilizer. The method is used for effectively returning agriculture-forestry waste to a field and solving the pollution problems caused to an environment and soil in the stacking and incineration processes of the pruned branch and the obsolete fruit tree of the apple tree.

Description

technical field [0001] The invention belongs to the technical field of agricultural and forestry waste treatment and clean composting product development, and relates to a method for producing bio-organic fertilizer by pruning apple trees and eliminating fruit trees. Background technique [0002] Agricultural and forestry waste refers to the organic substances that are discarded during the harvesting and processing of agricultural and forestry crops, mainly including plant residues such as crop straw, leaves, fruit trees and prunings generated in the process of agricultural and forestry production. The main components are Lignocellulosic. In recent years, with the continuous development of the planting industry, etc., the amount of agricultural and forestry wastes has increased day by day. Taking the fruit tree planting base in Shaanxi Province as an example, its nearly 10 million mu of apple trees are pruned every year to produce fruit tree branch wood and eliminated newer...
