一、水平沟整地模式水平沟在山坡上呈带状排列,带宽2米,带间隔2米,带内水平。每2米用打孔机打一深1-1.5米的炮眼,每炮用炸药1公斤,进行爆破整地,使爆破松裂的基岩蓄水层在2米以上,然后整平培埂,带内炮眼处即栽植穴。该模式因采取爆破整地,改变了土壤母质及风化层的物理结构,加速了土壤的成土过程,有利于蓄水保土。此模式适用于山区片麻岩地区整地造林,一般在山坡中下部、坡度15—25度之间应用。二、水平库整地模式水平库在山体上呈品字型排列,每亩设计10-12个,每个水平库放一炮或两炮,炮眼一般1.5—2米深,爆破后修成长6米、宽2.5—3米的水平库,水平库的中心挖1×1×0.5米的蓄水坑,在蓄水坑的上部修建平台,栽植果树。每库控制坡面面积55—83平方米,在左、右上角呈45度角的位置,各挖深、宽各30厘米的拦水沟,培高、宽各30厘米的拦水埂,拦水沟与沟相连,埂与埂相连。该模式既有利于拦水、蓄水、保水,又有利于坡体稳定和植被保护,同时还 First, the level of the whole pattern Ditch horizontal groove on the hillside was banded, with a bandwidth of 2 meters, with an interval of 2 meters, the band level. Every 2 meters with a punch hit 1-1.5 meters deep hole, each gun 1 kg of explosives, blasting site preparation, so that burst bedrock aquifer crack in more than 2 meters, and then leveling culture 埂, belt Within the hole at the planting hole. Due to the blasting site preparation, this model changed the physical structure of the soil parent material and the weathering layer, accelerating the soil forming process and benefiting water and soil conservation. This mode is suitable for afforestation in the gneiss area of ​​the mountainous region, generally in the middle and lower part of the hillside with a slope of 15-25 degrees. Second, the horizontal reservoir leveling model horizontal reservoir in the mountain was arranged in the font, design 10-12 acres per mu, each level library put one or two guns, the hole is generally 1.5-2 meters deep, after the blast repair 6 meters , A width of 2.5-3 m horizontal reservoir, the center of the horizontal reservoir dug 1 × 1 × 0.5 m of the storage pit, the upper part of the reservoir to build a platform for planting fruit trees. Each library control slope area of ​​55-83 square meters, in the left and right corner was 45-degree angle position, the dug deep, wide 30 cm of the ditch, Pei-high, wide 30 cm of water blocking, Ditch and ditch connected, 埂 and 埂 connected. This model is not only conducive to water, water, water, but also conducive to slope stability and vegetation protection, but also
