How do you remove moss from stones? How do you make moss grow on ordinary stones?

There are many types of moss removed from stones. It can easily remove the moss by exposing it to the sun, and if you want the moss to go out of the tree, you have to pull the knife fish.

After the stew is finished, pour hot water with salt water and scald Xingtai will grow again, so it is said that the moss grows on the stone is in a damp and damp place to get the moss, and that's it, this is a fungus.

The phenomenon of moldy hair.

1.Scrape off the moss with a razor blade in advance and then clean it with moss to increase the cleaning effect.

2.For the moss in the severe area, if necessary, it needs to be wrapped in a plastic bag to allow the moss microstructure on the surface to be properly decomposed, and after it has been decomposed, the residue can be left behind.

3.In use, do not splash the moss on your eyes, if you accidentally splash it, you need to wash the part of your eyes with plenty of water.

The stone is cleaned, then exposed to the sun, poured with hot water, and then brushed with a brush.

Transplant some mossy soil and water it frequently in a cool, damp and ventilated place.

Put it in a mossy place, water it for a few days, and it will be there.

Although it is confirmed that the demand curve arises naturally from the theory of consumer choice, the derivation of the demand curve itself is not a theory that proposes consumer behavior. Simply determining how people react to change doesn't require a rigorous analytical framework. However, consumer choice theory is extremely useful.

As we will illustrate in the next section, we can use this theory to more deeply determine the factors that determine family behavior.

Instant Answer Draw budget constraint lines and indifference curves for Pepsi and pizza. Illustrate what happens to the budget constraint line and consumer optimum when pizza** rises. Use your graph to divide this change into income effects and substitution effects.

Four applications. Now that we've established the basic theory of consumer choice, we can now use it to illustrate four questions about how the economy works. However, since each problem involves family decision-making, we can address these issues with the consumer behavior model we just proposed.

Are all demand curves sloping to the bottom right?

In general, when an item** goes up, people buy less. Chapter 4 refers to this normal behavior as the law of demand. This pattern manifests itself in the demand curve sloping to the lower right.

However, as far as economic theory is concerned, the demand curve also sometimes slopes to the upper right. In other words, consumers sometimes defy the law of demand and buy more when one item rises. To illustrate how this can happen, look at Figure 21-12.

In this example, the consumer buys two items – meat and potatoes. Initially, the consumer budget constraint line was a straight line from A to B. The best advantage is c.

When the potato ** rises, the budget constraint line moves inward and is now a straight line from A to D. Now the best thing is e. It is important to note that the rise in potatoes has led consumers to buy more potatoes.

Stone mold remover can be used.

1. Remove the surface energy of the stone.

Removed contaminants. Note: Do not use a wet rag, this will expand the contamination surface;

2. Evenly apply the stone mold remover to the stone surface. and let the reaction stand for 10-30 min.

3. Deep clean with a wire brush to remove the mossy "corpse".

4. Clean with water and let it stand to dry.

5. Evenly apply the impermeable treatment agent to the stone surface.

Let the stones grow moss right away, water them more often, and block the sun with a blackout cloth.

Moss is a generic name for bryophytes, which attach to the surface of objects and spread and grow, so it is also called moss. The moss is emerald green in color, the stem is as thin as silk, and it can be attached to the dark and damp and inaccessible places such as mountain rocks, pools, roof tiles, decaying walls, and wetlands like hair, and it is a very inconspicuous but very interesting plant.

Growing environment. It grows all year round in wetlands, walls, wells, roof tiles and water.

Distribution. It is an aquatic bryophyte, emerald green, which grows in water or in the shade of land.

Application in landscaping.

Bryophytes are delicate, dense and full of vitality, and their application forms in the garden are also rich and diverse, and can be matched with different scenes, different materials, and different terrains to produce completely different effects. It is mainly used in park greening, roof greening, vertical greening and home gardening to create an elegant and unique plant landscape.

Adverse effects. Moss competes with aquatic weeds and other algae for nutrients, excessively consumes nutrients in the water body, destroys the normal material metabolism of the pond, and makes the aquaculture water body lean. Consequences of thin water:

The growth of aquatic weeds was inhibited; The destruction of the periodic growth of plankton leads to the imbalance of algae in the water body, which will affect the normal growth of crayfish, crabs and fish.

The water body with a large number of moss growth, the water quality is clear and transparent, and the sunlight shines directly on the pond, which increases the stress response of crayfish, crabs and fish, and the long-term stress response can easily lead to the decline of the immunity of the farmed animals and lead to lesions.

Moss grows and multiplies in large quantities, and it is easy to entangle crayfish, crabs, and fish, and the entangled crayfish, crabs, and fish basically cannot struggle out, and can only starve to death.

Dead moss blows to the corner of the pond or sinks to the bottom with the wind to deteriorate, in addition to emitting a foul smell, in the process of decomposition will also consume dissolved oxygen in the water body, produce a lot of harmful substances, resulting in the reduction of dissolved oxygen in the aquaculture water, ammonia nitrogen, nitrite, hydrogen sulfide and other harmful substances increase, so that the water quality becomes poor, resulting in crayfish, crabs, fish hypoxia.
