Fish-scale pit soil preparation and forestation method

Abstract

The invention discloses a fish-scale pit soil preparation and forestation method. The fish-scale pit soil preparation and forestation method includes the steps that firstly, a plurality of rows of crescent-shaped pits are dug in a mountainous region or a sloping field from top to bottom at intervals, the pit surfaces of all the pits are lower than an original slope surface, a contour line serves as a datum line of the edges of all the crescent-shaped pits in each row, and two adjacent rows of the crescent-shaped pits are formed staggeredly; then, a fish-scale plate is fixed to the outer side,away from the slope surface, of each crescent-shaped pit by tightly adhering to the inner wall of the pit, and degradable mulching films are laid on the inner walls of the fish-scale plates and at thebottoms of the crescent-shaped pits; finally, after seedlings are planted into the pits, the pits are filled with improved soil imported from other places. By adopting the fish-scale pit soil preparation and forestation method, the staggeredly formed crescent-shaped pits are adopted, the fish-scale plates are fixed into the pits, and the degradable mulching films are laid in the pits, so that thefish-scale pit soil preparation and forestation method has the effects of water collection and storage, water and soil loss can be effectively reduced, and the runoff utilization effect is improved;therefore, the survival rate of the seedlings is effectively increased; shrubs are adopted to weave the fish-scale plates and can be obtained from local resources, a weaving method is simple and low in cost, and the fish-scale plates are free of soil pollution, environmentally friendly, firm and durable.

Description

Technical field [0001] The invention belongs to the technical field of drought-resistant afforestation, and mainly relates to an afforestation method, to be precise, to a fish-scale pit site preparation afforestation method suitable for difficult sites, so as to improve the afforestation survival rate of difficult sites. Background technique [0002] Difficult sites refer to high and steep deserted slopes, sand eroded land, rocky desertified mountains, coastal beaches, dry river hot valleys, arid and barren rocky mountains, saline-alkali land, collapsed landslides and debris flow accumulation, heavily polluted land, mining relics, high and steep road edges Site types where afforestation is difficult such as slopes. The vegetation in the difficult site is sparse and eroded strongly, and its ecological construction and ecological restoration are very difficult. Summary of the invention [0003] The purpose of the present invention is to provide a fish-scale pit land preparation aff...
