Upper cover of plant cultivation box

Abstract

The invention relates to an upper cover of a plant cultivation box. The upper cover comprises a cover body and a breathable film, the cover body is provided with a gas hole, the breathable film is arranged in the gas hole of the cover body and provided with a filter material and at least one supporting material, and the supporting materials are arranged on one side face of the filter material. The filter material is used for filtering gas passing the gas hole so that external microorganisms, bacteria and the like cannot pass the gas hole, the supporting materials arranged on one side face of the filter material are used for enhancing the structural strength of the filter material, the germ-free condition in a box body can be really maintained when the box body of the plant cultivation box is covered by the upper cover, and growth and development of plant tissues are facilitated.

Description

technical field [0001] The present invention relates to a plant cultivation box, in particular to an upper cover of a plant cultivation box. Background technique [0002] In order to facilitate the cultivation of plant tissue, plant seedlings or smaller plants, and to facilitate transportation, the planters will place the plants and their required soil or nutrients in a plant cultivation box, using the box body of the plant cultivation box and the upper The tight combination of the covers not only ensures a good airtight effect between the two, but also prevents the box body and the upper cover from being separated from each other during transportation. [0003] However, in order not to affect the normal growth and development of plant tissues, the plant culture box needs to have considerable air permeability, so usually an air hole is opened on the upper cover, and a non-woven breathable film is attached to the air hole for lifting the box. The gas exchange rate inside and...

Problems solved by technology

[0003] However, in order not to affect the normal growth and development of plant tissues, the plant culture box needs to have considerable air permeability, so usually an air hole is opened on the upper cover, and a non-woven breathable film is attached to the air hole for lifting the box. The gas exchange rate inside and outside the body, but the pores of the non-woven breathable membrane are too large, so the effect of blocking external microorganisms is limited

Therefore, when the upper cover with non-woven breathable membrane is combined with the box body, it is difficult to ensure the aseptic state in the box body, which will affect the growth and development of the plant tissue placed in the box body.
