Embodiment 1

[0019] Collection of tree branches: During tree management and protection in spring and autumn, collect the stems and branches produced by pruning, and store them properly after drying in a ventilated place;

[0020] Material preparation: crush the dried branches and stems into 5cm large particles with a pulverizer, and mix them thoroughly;

[0021] 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;

[0022] 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, with urea as the regulator, calculate the amount of urea required when the C / N value of the adj...

Abstract

The invention relates to a method of quick composting tree branch and trunk residual bodies by virtue of chemical-biological combination and in particular relates to a method of quick decomposing the tree branch and trunk residual bodies in arid and semiarid areas. The method comprises the eight steps: tree branch and trunk collection, material preparation, site selection, sampling calculation, material C / N value regulation, humidity control, litter making and process treatment. With the adoption of the method, the purpose of quick composting the tree branch and trunk residual bodies is reached mainly by virtue of a mode of adding an FeSO4 solution and inoculating a microorganism straw decomposing agent, and the problems that tree branches and trunks are slow in natural decomposition and composts are generally long in wood fiber humification period of the branches and trunks are solved. The invention provides an effective method for resource utilization of tree branch and trunk residual bodies and the like with higher lignin content and cellulose content and provides a scientific basis for making urban garden greening management decisions.

Description

technical field [0001] The invention belongs to the technical field of litter decomposition and regulation, and in particular relates to a method for rapidly composting rotting tree branch and trunk residues in arid and semi-arid areas by combining chemical and biological methods. 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 ...
