Embodiment 1

[0017] Expand the tree hole: expand the tree hole at the base of the trunk in the forest land, the circular specification is 1m in diameter and 0.5m deep;

[0018] Collect litter: in autumn and winter or early spring, collect the litter in the woodland to the nearest tree hole,

[0019] Sampling calculation: Sampling the collected litter, weighed, dried at 65°C to constant weight, measured its moisture content, and analyzed the organic C and total N content, calculated the C / N ratio, and calculated the litter by the sample basket method According to the measured moisture content, calculate the dry matter per unit volume of litter, and calculate the amount of C that needs to be added per unit volume of litter when the C / N ratio is adjusted to 25:1 based on the known actual C / N ratio of litter. The amount of / N ratio regulator (the present invention selects urea as C / N ratio regulator);

Abstract

The invention relates to a method for promoting litters to decompose through microrelief modification, which comprises steps of expanding tree pits, collecting the litters, spraying microbial inoculums, covering the tree pits, irrigating and the like. The method creates proper microenvironment for decomposing the litters by adding the microbial inoculums and a C / N ratio regulator and modifying microrelief in the forest land so as to achieve the aim of quickly decomposing the litters. The method solves the problems of slow natural decomposition of litters of artificial forests, prominent fire hazard and potential nutrient loss in northwest arid areas, the simple, practical and effective technology of quickly decomposing the litters of the artificial forests in the arid areas is provided, and a novel method is provided for close-to nature management technology for the artificial forests. The method is simple and safe, is not limited by external environmental conditions, and can quickly and timely decompose the litters to increase soil organic matters and available nutrient in the forest land.

Description

Technical field: [0001] The invention belongs to the technical field of litter decomposition regulation, and in particular relates to a method for rapidly decomposing forest litter in temperate arid and semi-arid regions. Background technique: [0002] In Northwest China, in order to improve environmental conditions, reduce natural disasters, and protect urban safety, large areas of artificial ecological protection forests have been built around the city. It is very slow, which seriously restricts the material circulation, nutrient balance and soil fertility improvement of the plantation forest ecosystem, and the healthy growth of trees and the stability and sustainability of forest land are seriously threatened. In addition, with the gradual accumulation of undecomposed litter on the surface of the forest land, the increase of flammable substances also increases the fire hazard of the forest land. [0003] At present, single-layer arbor plantation accounts for a considerab...
