Add waterproof sandstone with a thickness of about 0.8cm, and then smooth it with a small brush; Spread the water moss evenly on the water-resisting layer, spray water to wet it, and then gently compact it by hand. The thickness of compacted water moss is about 0.5cm, not too much. It has the functions of absorbing and retaining water and preventing planting soil from infiltrating into the aquiclude.

Add planting soil and adjust the slope with a small brush. The planting soil in the foreground is not too thick for fixing moss, and the planting soil in the background is about three times as large as that in the foreground, about 3 cm; Hold the root of the plant with chopsticks or tweezers and insert it into the planting soil, hold the upper end of the plant with the other hand, and then dig up the soil to bury the root of the plant.

Plant plants as close as possible to the glass wall and arrange them closely from high to low; Put ornaments and props into the appropriate position of the glass and gently press and fix them; Break the moss into a proper size by hand, hold the false root of the moss with chopsticks or tweezers, open the leaves of the plant with the other hand, and put the moss in a proper position in the bottle.

Gently press the moss by hand to make it fully contact with the soil, and adjust the position of the moss by the way; Tilt the bottle and fill the gaps between the mosses with decorative sand, and the height of the sand should not exceed the mosses; Adding fine sand, pebbles and blue sand in turn; After putting the doll in front of the public, spray water on the micro-landscape until half of the aquiclude is filled with water, and the accumulated water cannot exceed the aquiclude.

Environmental protection bottle

Eco-bottle is to put some small animals and plants (providing oxygen) in a glass bottle, self-sufficient, without adding any food or opening the bottle, all living things can survive. This is an ecological bottle. The market for environmental protection bottles is relatively large, and the price goes up by tens of dollars.

Knowledge expansion:

Eco-bottle is "an artificially simulated micro-ecosystem formed by putting a small number of plants, animals and other abiotic substances that feed on these plants into a closed light-mouth bottle".

Eco-bottle is an interesting, dynamic and very useful tool in science teaching activities. Because most children like to raise and watch aquatic organisms such as fish in ecological bottles, this kind of raising and watching can increase knowledge, promote inquiry, enhance understanding and bring good enjoyment.
