Problems solved by technology

[0003] The red sandy soil in the Red Sand Ridge area is reddish brown, sandy loam or light loam, with a pH value of 4.0-5.5 and a soil thickness of 35-65cm; most of the shallower soil has been reclaimed as gardens In the shallow soil layer of some mountain back hills, sporadically grow horsetail grass or thatch, hawthorn thorns, etc., and there are pieces of exposed rock baldness, and some sparse lichens, earth horse palms and other low plants grow on the rock baldness; Ridges or gentle slopes with deep layers can be developed into arable land. However, due to the unobvious development of the red sandy soil profile, the soil is cold, the water and fertilizer retention capacity is poor, and the young seedlings do not grow old, the productivity of the crops has always been low.

Abstract

The invention discloses a three-dimensional ecological system of insect fungus sand and a construction method thereof. The ecosystem takes red sandy soil as the base, and the base is covered with humus layer and surface layer in turn; the humus layer is mainly composed of rotten leaves or fermented straw, insect sand and bacterial colonies. The construction method is mainly to pulverize the red sand soil to form a red sand soil base; add rotten leaves or / and fermented straws, add insect sand and colonies to mix in proportion, and cover the surface of the red sand base to form a humus layer; , cover the surface of the humus layer, spray bacteria liquid to form a surface layer; put in earthworms, plant flowers, grasses, grains and other crops after resting for 7 days, and introduce local surface insects to form a three-dimensional ecosystem of insect fungus sand. The three-dimensional ecosystem of insect fungus sand constructed by this method can grow vegetables and short-rooted plants within 3-6 months; medium-rooted plants can be planted in 6-12 months; long-rooted plants can be planted after 36 months to realize red sandy soil. The self-repair and virtuous cycle development of soil provide conditions for the development of ecological agriculture.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a three-dimensional ecological system of insect fungus sand and a construction method thereof. Background technique [0002] Taking Nanxiong City, Guangdong Province as an example, a kind of sandy red soil developed on the parent material of red sandstone is widely distributed in the subtropical region of my country, which constitutes a unique red sand ridge landform. Due to the soft texture of red sandstone, easy corrosion, and strong surface erosion, the terrain in these areas is broken, maoyuan, gentle slope, weathering, erosion, scouring, and soil erosion are extremely serious, and some scours expose the bedrock and form a bare The original flat and complete ground was eroded into mounds, forming the red sand ridge landform. [0003] The red sandy soil in the Hongshaling area is reddish-brown, sandy loam or light soil, with a pH value of 4.0-5.5 and a soil lay...
