Embodiment 1

[0022] Collection of tree branches: during tree management and protection in spring and autumn, collect the stems and branches produced by pruning, and place them in a ventilated place to dry and store them properly;

[0023] Material preparation: crush the dried branches and stems into 5cm large particles with a pulverizer, and mix them thoroughly;

[0024] Site selection: On the outer edge of Karamay urban area (nursery base), select an open area with relatively flat terrain and determine it as a composting site;

[0025] Sampling calculation: take samples of the materials to be composted, weigh them, dry them at a temperature of 65°C until they reach a constant weight, measure their moisture content, analyze the organic C and total N contents, and calculate the total carbon and total nitrogen contents of the materials The ratio (C / N) value, according to the actual C / N value of the material, using urea as the regulator, calculate the mass of urea required to adjust the C / N v...

Abstract

The invention relates to a method for quickly decomposing tree branch and trunk residues, which comprises the following steps: collecting tree branches and trunks, preparing the material, selecting a place, sampling and calculating, regulating the C / N value of the material, composting fading substances and processing. The method effectively ensures the composting material to have suitable C / N value, humidity and oxygen mainly by pulverizing, regulating the humidity and C / N value of the material by immersion and increasing the hide lifting frequency, thereby implementing quick decomposition of the branch and trunk residues. The method solves the problem of nutrient loss due to slow natural decomposition and incineration of municipal tree branch cutting substances in northwest arid regions, and provides a novel method for recycling municipal garden tree branch and trunk resources.

Description

technical field [0001] The invention belongs to the technical field of litter decomposition regulation, and in particular relates to a method for quickly decomposing tree branch residues in arid and semi-arid areas. Background technique [0002] With the development of economy and society, the area of ​​urban gardens and green spaces has increased rapidly, and the amount of garden green wastes such as pruning, thinning materials, lawn grass and litter produced in the process of greening and maintenance is also increasing. Under natural conditions, the nutrient elements contained in litter are gradually returned to the soil for reabsorption by plants after decomposition, which is very important for soil fertility maintenance and plant growth. However, in the actual process, in order to keep the environment beautiful and clean, a large amount of garden green waste mainly composed of lignocellulose is cleaned up as garbage, and then centralized and unified landfill or incinerat...
