A method to promote the formation of uniform litter and humus layer in slope broad-leaved forest

Abstract

The invention relates to a method for promoting the formation of uniform litter and humus layers in broad-leaved forests on slopes, which includes: measure 1: thinning or pruning to transmit light, and guiding the growth of understory shrubs and herbs; measure 2: setting up biological barriers, Prevent fallen leaves from falling down the slope; measure three: excavate a storage ditch to accumulate litter and accelerate decomposition; the storage ditch is dug on the side facing the slope of the biological barrier. The invention introduces artificial measures to increase the light conditions, guide the growth of shrubs and grasses under the forest, increase the retardation and absorption capacity of the underlying surface, prevent fallen leaves from going down the slope, dig ditches to increase the storage and retention capacity of ground litter, and the ditch surface Under the action of runoff erosion, the ditch wall collapses and naturally covers and compacts the litter in the ditch, contacts and mixes with the litter, which is conducive to the full contact between soil microorganisms and litter, and promotes rotting and slope land degradation. The formation of humus accelerates the decomposition of litter and improves the speed and ability of litter to return soil nutrients, which is of great significance to the fertilization and sustainable use of forest soil.

Description

technical field [0001] The invention relates to the field of sustainable utilization of forest soil, in particular to a method for promoting the formation of uniform litter and humus layers in broad-leaved slope forests. Background technique [0002] As we all know, forest litter and humus play an important role in the material and energy cycle of forest ecosystems, and the return of litter is the main source of forest soil nutrients, an important way for forests to improve soil quality, and a key to sustainable use of forest soils. Material basis. Forest soil cannot be effectively supplemented by litter decomposition for a long time, which will inevitably lead to continuous degradation of forest land soil, which is extremely unfavorable to the current important task of national land afforestation - the improvement of forest quality. In addition, litter and humus layers also play an extremely important role in regulating forest hydrology and maintaining water and soil resou...
