Embodiment 1
[0080] The east bank (2012) and the north bank (2013) of the artificial lake in Caofeidian District, Tangshan City, Hebei Province, with an area of 140 mu, was originally the Tanghai County Balitan Seawater Farm, which was excavated into artificial lake Qing (Qinglong Lake). The soil is coastal silt and muddy soil, and the soil soluble salt content is 1.84-3.84%. After the rainy season in the first year (after October), carry out land consolidation, digging drainage ditches, and laying water supply pipelines. In the spring of the second year, soil improvement and seedling planting operations will be carried out.
[0081] 1. Soil preparation: Roughly level the green area mechanically, and the ground height difference is less than 20cm.
[0082] 2. Digging drainage ditches: the width of the upper mouth of the drainage ditch is 3-4m, the width of the bottom is 1.0-1.5m, and the depth of the ditch is 1.5-2.0m. The area where trees are planted forms a terrace field with a width...

[0090] Hebei Xinhai Seawater Biotechnology Co., Ltd. Shrimp Breeding Farm, Nanpaihe Town, Huanghua City, Hebei Province, covers an area of 27 mu. The soil is coastal silt and silt soil with an average soluble salt content of 2.15%. Realize the improvement and greening of the year.
[0091] 1. Land preparation: As it is a greening of the factory area, the greening area is basically flat, and only the site has been cleaned up to remove building ruins, garbage, and weeds.
[0092] 2. Laying water supply pipes: Lay DE50 caliber water distribution pipes for each greening block, and leave an above-ground water outlet pipe every 50m. The water pipeline is buried 70cm below the surface.
[0093] 3. Laying hidden salt discharge pipes: Due to the greening of the factory area, it is inconvenient to dig open drainage ditches. A salt discharge pipe with a diameter of 50mm is laid for each greening block, buried at a depth of 80cm, and connected to the underground drainage system of the ...
Embodiment 3
[0100] Caofeidian Wetland Vegetation Restoration Project in Tangshan City, Hebei Province covers an area of 80 mu. The green area is made of excavated clay from mariculture ponds. The soil is not only sticky, but also has an average soluble total salt content of 4.77%.
[0101] 1. Soil preparation: Excavate the clay and dry it in winter and spring, then carry out mechanical rough leveling, the ground height difference is less than 20cm, and rotate the harrow twice to crush the large soil clods.
[0102] 2. Laying water supply pipes: Lay a DE50 caliber water distribution pipe in the east-west direction, and leave an above-ground water outlet pipe every 50m. The water pipeline is buried 70cm below the surface.
[0103] 3. Laying of hidden salt discharge pipes: a salt discharge pipe with a diameter of 50mm is buried every 15m in the north-south direction, and the buried depth is 80cm.
[0104] 4. Applying corn stalks: 33m of crushed corn stalks 3 / 667m 2 , Digging 50cm deep ...
