Method for planting trees in flooded areas of wetlands

Abstract

The invention relates to a method for planting trees in flooded areas of wetlands. Each planted tree is planted in a planting platform which is high in side wall openness and free of an upper cover and a lower bottom and assists a seedling support frame; each planting platform 0.5-1.5m in inner diameter and 50-70cm in height is built in a wetland in a manner that air bricks are arrayed in staggered layers; planted tree species are aquatic, hygrophilous or paludose tree species, have developed aerenchyma, are suitable for the wetlands and flooded-area waterish environments, and also have developed root systems high in roothold; each support frame is built by dwarf bamboos or sticks, and the height of a support on each tree is one fourth to one third of height of the tree. Through the method, the trees are ensured to grow fixedly and normally in the flooded environment. Besides, the method is novel, wide in use range, high in flexibility, convenient to operate and excellent in cost performance.

Description

technical field [0001] The invention relates to the field of wetland afforestation, in particular to a method for planting trees in flooded wetland areas. Background technique [0002] Wetlands, forests, and oceans are known as the three major ecosystems in the world. They are the ecological landscape with the richest biodiversity on the earth and one of the most important living environments for human beings. They are called the "kidney of the earth" and the "gene pool of species". The uniqueness of the wetland ecosystem lies in its special hydrological conditions, the interaction of land and water ecosystems, and the resulting special ecosystem functions. It has the functions of maintaining ecological balance, maintaining biodiversity and rare species resources, and conserving water sources and flood storage. The role and value of drought prevention, pollution degradation, climate regulation, groundwater replenishment, and soil erosion control. However, due to the non-per...

Problems solved by technology

However, the containers for container planting often have poor air permeability and water permeability, so that plants are often limited to the scope of the container, which is not conducive to the natural growth of their roots and the absorption of nutrients, and most of the containers used in container planting are disposable. Low, high cost, poor applicability

At the same time, the container is easy to rot and damage, the effective anti-wave fixation is poor, and it is easy to cause the loss of soil at the root of the tree; if it is not easy to rot, it may limit the growth of the root system of the tree, so the current container method is not conducive to the natural growth of plants in flooded areas for a long time

[0006] In summary, the method of planting plants in wetland flooded areas needs to be studied urgently, especially the method of planting landscape trees in wetland flooded areas is particularly needed, but has not been reported; a new method of planting is urgently needed in production practice, which can be used for The root soil and plants of newly transplanted plants are effectively fixed against waves, which is conducive to the free growth of roots in silt and soil, and is conducive to the natural growth of plants in flooded areas for a long time. At the same time, it has the characteristics of convenient operation and low cost.
