土壤的透气保湿性,是大多数室内盆栽花木正常生长的重要因素,为此,人们进行了不断的探索。这里介绍一种笔者最近设计的“气水分流式底孔罩”。结构如图所示:它像一顶“倒置的礼帽”。帽沿下部的钵底开有数个直径20毫米的气孔,罩壁开有直径3毫米的普通斜孔(罩壁厚度≥5毫米为宜),也可缝成宽5～10毫米的百叶窗式透气孔;罩壁的底部开有一圈直径2毫米的半圆形渗水孔。这种底孔罩的透气孔是专供换气用的斜孔,孔径大,但是不会跑泥,可以有效地提高土壤的透气吸湿性。另外,由于渗水孔不兼透气功能,因此孔径可以很小,且设在罩壁
The breathable moisture retention of soil is an important factor for the normal growth of most indoor potted plants. Therefore, people have been continuously exploring. Here I introduce a recent design “gas-water split-flow cover ”. Structure as shown: It is like a top “inverted hat ”. Bottom of the brim bottom of the bowl has a number of holes 20 mm in diameter at the bottom, the cover wall opening diameter of 3 mm ordinary oblique hole (wall thickness ≥ 5 mm is appropriate), can also be slit into 5 to 10 mm wide louvered ventilation Hole; cover the bottom of the wall open a circle diameter 2 mm semi-circular seepage hole. This bottom hole ventilation holes are designed for ventilation with oblique holes, large aperture, but will not run mud, can effectively improve the breathability of soil moisture absorption. In addition, since the water seepage holes are not air-permeable, the hole diameter can be small and provided in the cover wall
