Water-saving and fertility-maintaining type tree planting flower bed special for roof

Abstract

The invention relates to a gardening facility, in particular to a water-saving and fertility-maintaining type tree planting flower bed special for a roof. The tree planting flower bed consists of a flower bed main body, a planting cavity, a mud isolation pad, a stainless wire net, a water inlet valve, a drainage valve, an air bag, an air filled pipe, a sealing cover, a water storage cavity, a beam, a drainage pipe, an observation window and a water inlet pipe, wherein the internal space of the flower bed main body is divided into the upper planting cavity and the lower water storage cavity by an isolation belt which is formed by the beam, the stainless wire net and the mud isolation pad; the side wall of the water storage cavity is provided with the water inlet pipe, the drainage pipe and the air filled pipe; and the outer end of the air filled pipe is closed by the sealing cover, and the inner end of the air filled pipe is communicated with the strip-shaped air bag which is positioned in the water storage cavity. In the tree planting flower bed, the root of a tree can be watered from bottom to top, so water firstly reaches a water absorbing peak section deep in soil with the densest root tips, and the utilization ratio of the water is greatly improved; meanwhile, the tree planting flower bed has the advantages of fertility maintenance and is convenient to manage.

Description

technical field [0001] The invention relates to a gardening facility, in particular to a water-saving and fertilizer-preserving special tree-planting flower bed on the roof. Background technique [0002] The flower beds for planting trees built on the roof of the building completely depend on artificial watering for their water supply because their bottoms are not directly connected to the soil of the earth. However, for many years people have only been accustomed to watering the upper surface of the soil in the flower bed, allowing the water to slowly soak into the soil and finally reach the roots of the trees. Because the root system of the tree is well developed and the root tip is usually located at a deep place, and this is just the water absorption peak section of the tree root, most of the water poured on the soil surface has been absorbed by the surface soil during the process of soaking into the deep soil. The water in the surface soil is quickly evaporated, and th...
