Method and device for planting trees by accumulating rain water

Abstract

The invention discloses a method for planting trees by accumulating rain water. The method comprises the following steps: spreading a culture medium at the bottom of a tree well; placing a tree seedling above the culture medium, and placing a water accumulation unit in the tree well; placing a water release unit between the water accumulation unit and the root of the tree seedling; fixing the tree seedling; placing a rain water collection unit above the water accumulation unit; and connecting the rain water collection unit with the water accumulation unit, so that rain water collected by the rain water collection unit is stored in the water accumulation unit and is supplied to the root of the tree seedling through the water release unit. According to the method disclosed by the invention, the culture medium having a moisture retention effect can effectively complete an automatic rain water collection process, an automatic water accumulation process and an automatic water release process, thereby providing required moisture for the tree seedling and ensuring survival of the tree seedling; the method effectively utilizes the water resource and saves high labor cost; and due to the effects of rain water interception and accumulation, the method can effectively relieve urban inland inundation and water discharge pressure. Besides, the invention also provides a device for the method.

Description

technical field [0001] The invention relates to the technical field of tree planting, in particular to a method and device for planting trees by accumulating rainwater, which are suitable for ecological restoration in areas with drought and severe soil water shortage and urban greening projects. Background technique [0002] The ecological environment in arid areas is fragile, and serious soil erosion, land desertification, and water resource shortage are the main environmental problems they face. Vegetation construction centered on soil and water conservation plays an important role in maintaining ecological balance and improving ecological environment in arid regions. Therefore, in order to protect and improve the ecological environment, expand the forest area, and increase the vegetation coverage, afforestation is imperative. However, due to the traditional afforestation projects, a large amount of water is required to maintain the survival rate of trees and the landscap...

In addition, there is also a method of embedding a water reservoir in the tree pit, such as patent 03105075.1 providing a water-saving tree planting method, that is, burying a sealed container with water in the tree pit, and opening a small opening at the top of the container, Insert at least one lateral root of the sapling into the water container to achieve the purpose of water supply. This method is simple to operate and can improve the survival
