Method for irrigating trees by rainwater

Abstract

The invention relates to a method for irrigating trees in a city. The method mainly solves problems that rainwater cannot seep to underground environments due to hardening of ground surfaces of a city and water required by trees is insufficient. The method is characterized in that collected rainwater directly flows to an environment under the earth surface and acts on roots of a tree; a plurality of rain collectors and a water delivery pipe for communicating the rain collectors with the environment under the earth surface are mounted on tree trucks; the natural rainwater collected by the rain collectors flows to the roots of the tree via the water delivery pipe for communicating the rain collectors with the environment under the earth surface, and the quantity of the rainwater which flows to the environment under the earth surface is controlled by the aid of a water flow switch on the water delivery pipe, so that injury on the roots of the tree due to excessive water is prevented. The method for irrigating the trees has the advantages that the problem that rainwater is stopped from flowing into soil due to hardened ground surfaces can be effectively solved, and accordingly problems that water in trees is deficient, normal vital movement of the trees cannot be kept and even the trees die are solved.

Description

technical field [0001] The invention relates to a watering method for urban trees, in particular to a method for watering trees with rainwater. Background technique [0002] For the sake of beauty, the current city pays attention to "the loess is not exposed to the air", and the ground of the whole city is covered with cement, asphalt and masonry. When paving in places with trees, some do not leave tree pools for trees, or leave tree pools very small, and this kind of ground prevents rainwater from penetrating into the ground, so the rainwater that should have been obtained by trees flows into urban sewage with the sewer deal with the system. The water supply of urban trees can be completed by rainwater, and the main channel for rainwater to enter the tree body is through the soil to reach the root system, that is to say, the main channel for trees to absorb water is the ground, however, the hardened ground blocks the rainwater from entering The channels of the soil preven...
