Forestation technology using mangrove forest plant to convert pond to forestry

Abstract

The invention discloses a forestation technology using mangrove forest plant to convert a pond to forestry. The method comprises the steps of building planting ridges and water channels in a waste pond, arranging a water gate, controlling water in the water channels to communicate with outside by a gate in the water gate, wherein multiple planting ridges can be arranged according to the size of the pond; opening the gate of the water gate to enable water in the pond to change along with external water, and determining the high water mark in the pond, wherein the heights of the planting ridges are selected to be lower than the high water mark by 10cm, the bottom areas of the planting ridges are larger than the opening areas and vertical section shapes of the planting ridges are a trapezoid with a narrow upper part and a wide lower part; planting tree seeds into the planting ridges, encircling the planting ridges with a gauze element of about 20 meshes, opening the gate to communicate water in the pond with an outside water body and enable the water in the pond to change along with the tide change of the outside water body, inspecting in each month and timely replacing dead individuals. The method has the beneficial effect the tree seed survival rate of the mangrove forest is high by turning the pond to forestry.

Description

technical field [0001] The invention belongs to the technical field of mangrove afforestation, and relates to an afforestation technology for returning ponds to forests by using mangrove plants. Background technique [0002] In the past 20 years, more than 1 / 3 of the world's mangroves have disappeared. The land reclamation movement in the 1960s led to the first large-scale destruction of mangroves in my country; since the 1980s, people have opened ponds on the mangrove tidal flats for cultivation, which once again caused large-scale destruction of mangroves in my country. Studies have shown that the sharp decline of mangrove resources will not only lead to the deterioration of the coastal ecological environment, a 60% to 90% reduction in the production of marine economic animals in tidal flats, and a significant decline in offshore fish fry resources, but also cause red tide disasters, marine land erosion, and increased port deposition rates. A series of problems such as th...
