Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with specific embodiments, but the present invention is not limited to the following examples.

[0025] Such as figure 1 As shown, strip ditches 1 are dug according to the plan on the beach to be improved. The cross-section of the excavated strip ditch 1 is trapezoidal, 1m wide at the top, 0.3m wide at the bottom, 0.6m deep, and several meters long. Strip ditch 1 is too shallow to be unfavorable for the fixing of seedlings, too deep and too wide to waste manpower, too little soil that can be improved in too narrow ditch is also unfavorable for the growth of later stage seedlings.

[0026] Such as figure 2 As shown, the water blind ditch 2 is dug at the bottom of the strip ditch 1, and the ditch soil is temporarily put aside. The water blind ditch 2 is 20 cm wide and 30 cm deep. The water blind ditch 2 is connected with the drainage well next to the transformed beach, so that The water flows direc...

Abstract

The invention provides a coastal protection forest construction method comprising following steps of digging strip-shaped grooves according to a protection forest planting mode, digging pouring blind ditches at the bottoms of the strip-type grooves, filling the pouring blind ditches with rock ballast bags; paving a seepage-proof layer on the groove walls of the strip-shaped grooves; mixing the dig groove soil with crushed straws, crushed weeds or other wild vegetations for improving the soil, and refilling the strip-shaped grooves with improved soil; piling furrowing piles on the strip-shaped grooves refilled with the soil; and removing salt, and planting nursery-grown plants. The invention has advantage that problems of low survival rate, low reservation rate and low arboreal growth speed of coastal protection forest are solved.

Description

technical field [0001] The invention belongs to the field of protection forest construction, in particular to a construction method of coastal protection forests. Background technique [0002] Coastal shelterbelts are located on the edge of the coast and are an extremely important shelterbelt construction in the country. The total length of the country's coast is 18,340 km. Because it is close to the sea, the salt content of the soil is generally above 1%, and most of the soil is relatively muddy, which brings great difficulties to the construction of shelterbelts. Over the years, the country has invested a lot of money in the construction of shelterbelts, but the retention and growth of forest belts are not optimistic. The main reason for this is that the soil has not been thoroughly improved, and the water, fertilizer, air, In hot conditions, even the salt-tolerant seedlings planted have poor growth. Combined with this reality, after repeated research and practice, we mu...
