Embodiment 1

[0020] In early March 2005, in Dongtai City, Jiangsu Province, the inner slope, outer slope and Qingkan of the seawall were selected, and tree holes of 40×40×40cm were dug according to a certain row spacing, and cake fertilizer or compound fertilizer was applied in the tree holes 1200~1800kg / hm 2 . On the inner and outer slopes of the seawall, select 10,889 black locust saplings with a height of 70-100 cm and a ground diameter of 1-2 cm. Before planting, add water and soil to polyvinyl alcohol to make a slurry (polyvinyl alcohol, water and soil according to 1:300:60), fully immerse the root system of the seedlings in the mud and dip the roots for 1 to 5 seconds, and plant as they dip. Plant according to the row spacing of 350cm×350cm, and pour enough water to fix the roots; select poplars with a thickness of 2-3cm on the Qingkan, cut them into 4168 cuttings with a length of 30-40cm, and put the cut cuttings Soak in clean water for 4-6 hours to make it fully absorb water, the...

Abstract

The invention discloses a method for improving the survival rate of forestation for a seawall-based forest belt, which comprises the following steps of: digging tree pits and applying a base fertilizer on inner and outer slopes of the seawall in February and March; selecting high-grade robinia tree seedlings, adding water and soil into a water-retaining agent and mixing into slurry before planting, dipping seedling roots in the slurry, planting while dipping, and watering enough rooting water after planting; selecting poplars with the thickness of 2 to 3cm on a green bank and shearing into cuttings with the length of 30 to 40cm, and soaking the cuttings in clear water so as to fully absorb moisture; quickly dipping the cuttings in the water-retaining agent for 3 to 5 seconds and inserting the cuttings into the tree pits, wherein the depth is that the upper shear mouth is 1cm away from the ground, and watering enough; and cutting couch grass into blocks and planting in an open space point by point. The method for improving the survival rate of forestation for the seawall-based forest belt has the advantages of making the survival rate of forestation improved to 85-96 percent and overcoming the defects that the traditional planting mode has low survival rate of forestation, slow forestation and poor protection effect. Therefore, the seawall-based forest belt has the expected disaster-resistant and windproof effects 3 to 5 years earlier.

Description

technical field [0001] The invention belongs to the field of coastal shelterbelt planting, and relates to a method for planting tree species in coastal shelterbelt base trunk forest belts. Background technique [0002] my country's mainland coastline is 16,125km long. Within the narrow and long coastline, disastrous weather such as typhoons, rainstorms, and tornadoes cause serious harm to coastal people's lives and industrial and agricultural production. It is necessary to build a coastal shelterbelt system to resist and reduce the degree of harm. As the main part of the coastal protection forest system, the seawall base forest belt not only undertakes the functions of soil fixation and dike protection, tide protection and disaster resistance, but also has the functions of wind protection, flying salt prevention, fog prevention, fish protection and disaster avoidance. Due to the harsh coastal climate conditions, not only the high salinity content of the soil, but also the pl...
