The tide soil is the secret weapon of the succulent world.

Sometimes there are continuous rainy days, and there are many muggy and humid weather, especially for meat friends in the south of the Yangtze River. In this weather, the law of dryness and dryness seems to become inapplicable.

It has to be watered. As soon as it is watered, the whole basin of soil will be wet, and it won't dry for a long time.

If you can pour very little water into it, then the whole basin of soil will become damp. What should I do about this?

Some meat friends with conservation experience know that Chao soil is actually a good thing. Because Chaozhou soil has several characteristics that meat likes very much.

First of all, there is water in it, which means that the meat can drink water, and the roots will not dry up because of lack of water.

Second, the moisture content is just right, so that the soil will not be too wet to become airtight.

Third, it can keep water in a state that is available but not enough, stimulate meat's water storage and sun protection instincts, and make meat fat and beautiful.

So what kind of soil is tidal soil?

First of all, there should be moisture in the soil, and there is an obvious sense of moisture in the hands. Then, the soil particles will not stick to each other because of moisture, and as soon as they are clenched together, their hands will immediately disperse, the hands that have grasped the soil will not stick to the soil debris, and others will not see that you have just scratched the soil if you gently pat your hands and do not wash your hands.

The water content of soil with different composition is different in fluvo-aquic soil. Yellow clay, for example, is always in a state of either mud (wet soil) or consolidated dry powder (dry soil), keeping the damp state very short, so yellow mud is not a suitable meat plant. And pure sand is not easy to show the state of tidal soil, fine sand will stick to each other as soon as it is watered, and sand sculptures are made in this way, while sand that is too coarse can only rely on a little water on the surface of sand grains and will soon return to a fully dry state.

Many meat lovers' understanding of Chao soil is higher than the humidity that meat really needs. If a hygrometer is buried in fluvo-aquic soil, the hygrometer should show 70% to 80% humidity. If the humidity shown by the hygrometer buried in the soil is already 100%, the fluvo-aquic soil is too wet to have the effect we want.

We have often heard of the method of topping the basin of tidal soil. Why should the tidal soil be put on the basin instead of watering it? Because it is very difficult for watering to produce the effect of fluvo-aquic soil. So we can artificially wet the soil and then put it on the basin to create a damp soil environment for the new meat.

By mixing and dough-style method of adding water while stirring, we can turn any plant material into fluvo-aquic soil, which is very simple. But after the basin, it is very difficult to create fluvo-aquic soil again, because you lack the means of mixing.

Noodles and meat friends all know that after pouring water into the flour, if you do not stir it, the water will not slowly infiltrate the flour, but will always gather in the place where you pour water, forming a puddle, while the flour in other places is still completely dry.

Doesn't flour absorb water? Apparently not. It is because the flour particles are very small, which makes a large number of flour particles have a very large surface area. The surface tension of water will limit the flow of water, so that the water will not infiltrate the flour, but let the water gather into droplets.

Soil with too much debris, such as peat, is similar to the form of flour, which makes it impossible to turn the soil into fluvo-aquic soil by a small amount of watering.

Another example in life is rice washing and cooking. Dry raw rice at the bottom of a pot, as long as a small amount of water is added to it, and soon all the rice is wet.

The rice particles are of the right size, which not only does not restrict the flow of water, but also causes the water film to spread along the gaps between the rice grains. However, raw rice does not absorb water, so the water gathers between the grains.

It's like wet sand. Either the rice grains are too wet to stick together, or there is too little water to stay damp for a long time.

The fluvo-aquic soil we expect is actually more like cooked rice (assuming that rice grains do not stick together). There is no water between rice grains, but there is a lot of water inside them. As the water evaporates, the water inside the rice grains is constantly released, keeping the whole bowl of rice in a damp state for a long time.

So, if you want to create fluvo-aquic soil by watering, then the soil needs to meet two important conditions.

First, there should not be too many clastic plants, which will affect the ability of water to infiltrate in the soil. Peat, coconut bran (coconut brown with long fiber is much better), plant ash and dust from all kinds of granular plants are all in this category.

Second, the particles in the soil must have internal pores in order to absorb the water between the particles, prevent the interplant water from sticking the particles together and turn the soil into wet soil. Red jade soil, gold plant stone, deer marsh soil, light stone, diatomite, volcanic rock and so on all belong to this kind of plant material.

So when you find that your soil always needs a lot of water to keep moisture in every corner of the flowerpot, it means there is too much debris in the soil. The addition of the above-mentioned granular plants with internal voids can significantly improve the situation that the soil is not easy to be infiltrated.

Red jade soil, which is often highly recommended by senior meat lovers, is a kind of plant material that can easily turn into Chao soil.

Meat friends who have red jade soil on hand can do an experiment together, use a small black square to install a small basin of red jade soil, and then pour a little water on the surface, not a lot. Then wait quietly for 10 minutes to pour out the red jade soil. You will find that the whole basin of red jade soil is in a very uniform wet state. This is the advantage of red jade soil, which is a lazy soil. if you want to water it thoroughly, no problem. If you want to make the soil damp, then you should water less. Unless you water too little at a time, you won't get wet and dry and the roots will grow up.

Red jade soil is really a very good thing. When mixing soil formula, the ability of absorbing and retaining water can be compared with red jade soil. Meat friends who have their own soil, if you are not sure whether your soil is good enough, you can also compare it with red jade soil, and you can easily judge the level of your soil.
