A controlled-release fertilizer box, a soil layer partition and an ecological tree pool

Abstract

The invention discloses a controlled-release fertilizer box, a soil layer partition and an ecological tree pool. The controlled-release fertilizer box is composed of placing parts and a closing part wherein the placing parts and the closing part are spliced with each other, a plurality of degradable fertilizer bags are placed in the placing part, wherein the spaces among the above fertilizer bags are filled with fertilizer, the controlled-release fertilizer box is buried in soil, and the fertilizer is released into the soil at different times with the difference of the degradation period of each layer of the fertilizer bags, so that requirements of a plant at different growth stages are satisfied, and the costs of subsequent plant maintenance are lowered; the soil layer partition made from the controlled-release fertilizer boxes has the advantages of not only long fertility, but also water insulation and heat preservation and soil supporting which ensures the permeability of the soil through avoiding soil layer settlement; the ecological tree pool containing the soil layer partitions has the advantages of strengths of the above soil layer partition and controlled-release fertilizer box and low management cost, and is beneficial to the long-term healthy growth of the plant.

Description

technical field [0001] The invention relates to the technical field of landscaping, more specifically, it relates to a controlled-release fertilizer box, a soil layer partition and an ecological tree pool. Background technique [0002] When planting trees on paved ground, a piece of unpaved land should be reserved around the tree, usually called a tree pond or tree hole. In order to allow the trees planted in the tree pool to grow healthily, it is necessary to ensure the soil fertility and air permeability in the tree pool soil layer. [0003] The tree pool in the prior art, such as the ecological tree pool proposed by the Chinese patent with the patent notification number CN205681975U, mainly includes a pool body, and the pool body is sequentially provided with a water-permeable layer, an aquifer and soil from top to bottom. layer, a large number of refractory plastic materials are used in the above scheme, which will not only limit the growth of trees, cause soil environm...

Problems solved by technology

[0005] Aiming at the problems that soil fertility is lost in the later stage of tree planting but fertilization is difficult, and soil air permeability becomes poor and affects the normal growth of trees in practical applications, the first object of the present invention is to propose a controlled-release fertilizer box, and the second object is to provide a fertilizer that utilizes the above-mentioned controlled fertilizer. The third purpose is to provide an ecological tree pool containing the above-mentioned soil layer partition, and the specific scheme is as follows:
