Muddy coastal zone plant groove or plant hole afforestation method

Abstract

The invention relates to a muddy coastal zone plant groove or plant hole afforestation method. The method includes the following steps: (1), excavating strip-shaped plant grooves or plant holes for plant cultivation at a reclamation area (dredger fill is sea mud) or a muddy coastal zone planning forest zone building area, and burying an underground pipe; (2), using planting soil in the plant grooves or the plant holes in depth of 60-70cm from the surface layer, laying a blind pipe in a blind pipe trench, backfilling salty soil after externally-wrapping filter materials are filled around the blind pipe fully, and laying a saltpeter layer between a salt soil layer and a planting soil layer; (3), blending cow dung, bio-organic fertilizer and turf in a planting soil layer of a reclamation sea mud area, using cow dung, bio-organic fertilizer and plant straw bits in a planting soil layer of a clayey soil area, uniformly blending, planting arbores and shrubs, and entering a period of maintenance and water-salt directional adjustment and control. By the method, afforestation cost can be effectively saved.

Description

technical field [0001] The invention relates to an afforestation method, in particular to a method for afforestation of a planting groove or a planting hole, which is mainly aimed at the rapid construction of a protective forest belt and urban street trees in the muddy coastal zone and its reclamation area. Background technique [0002] The coast around the Bohai Sea is a plain wind, tide, drought, flood, salt, and alkali area dominated by muddy coasts, and its basic features are delta alluvial plains or marine plains formed by the alluvial of the Yellow River and Hai River. The coastline is straight, the beach is wide, the terrain is flat, saline-alkali waterlogged, the site conditions are poor, and there are few tree species suitable for afforestation, resulting in serious breaks in coastal protection forests on the 1194-kilometer mainland coastline from Jingtang Port to Qikou in Tangshan, Hebei. In recent years, due to the increasingly scarce urban land resources, coastal...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: specific burial depths of shrubs and arbor hidden pipes for planting shrubs and arbors in shelterbelts in silty areas and sea reclamation areas are proposed to solve the problems of groundwater level and desalination and salt control effect, and the concentrated distribution layer of plant roots Set stone salt in the lower part to solve the problem of secondary soil salinization in the early stage, apply cow dung, bio-organic fertilizer and peat (or plant straw debris) to improve the soil in the micro-zone of planting holes, change the water-salt state of the micro-zone soil, and regulate the water and salt through directional control achieve the purpose of exchanging time for space
