Let's design a semi-soil moisture basin to promote the better growth of flowers.

Oxygen and water are the two major factors for the healthy growth of plants. If the water is large, the root will rot, and if there is little water, it will wither. After three years of watering, it is difficult for many beginners to master the watering technology, ruining many flowers that should bloom. Oxygen and water, there seems to be a certain degree of repulsion, many veteran gardeners choose to use loose water-retaining medium, careful irrigation methods to balance oxygen and water, but can only be so?

I invented a new type of flowerpot, which innovates in the spatial structure, and its core is to build a stable and open humid air layer (hereinafter referred to as the humid layer) in the middle of the flowerpot, and the plant roots run through it. Thus greatly meet the needs of plant roots for air and water. That is, it can help beginners solve the problem of watering, and for veterans, it can promote the better growth of flowers.

The flowerpot is divided into two parts: inside and outside. The outer edge of the inner basin can be placed on the outer basin, and the outer basin should be significantly higher than the inner basin.

The bottom of the inner basin needs to be porous and can be perforated by itself to facilitate the extension of plant roots. A small hole is drilled on the side of the outer basin about four centimeters below the bottom of the inner basin for gas exchange and balancing water level. this position can be flexibly adjusted according to the specifications of the basin.

Put some water in the outer basin, fill the inner basin with soil, put it on top of the outer basin, and you can use it.

There are many materials that can be used. In order to facilitate understanding, a bucket and plastic basin are used as raw materials to make a steam basin, as shown in the figure:

The small hole limits the maximum height of the water, so that it cannot come into contact with the inner basin, so that a moist air layer can be formed between the bottom of the inner basin and the water surface of the outer basin.

Under normal planting, the plant roots will pass through the wet layer, and the advantages of this design are as follows:

1. Structural drought tolerance, but plant roots can obtain water from the moist layer and the outer basin until the water in the outer basin dries up.

two。 Structural waterlogging resistance, plants protruding from the inner plate of the root system, through the moist layer, moist air can provide enough oxygen, will not be drowned by water.

3. Keep fertilizer, watering leakage, fertility will not be lost, but stored in the water of the outer basin.

4. It is easy for the soil to change to water, because the plant grows to the root system of the outer basin water layer, that is, the hydroponic root that adapts to hydroponic culture, which can be planted under hydroponic culture at any time.

5. It is easy to detect soil fertility. Directly take out the water in the outer basin, steam dry the proportion of the precipitation, or directly measure the electrical conductivity and calculate the fertilizer concentration.

6. The cleanliness is high, and the soil will not scatter from the bottom during transportation, because there is no hole in the bottom of the outer basin, so just plug the side air hole with your fingers.

7. It uses less soil because the root system can absorb water and nutrients from the water passing through the outer basin, and can obtain oxygen from the wet layer, which is not simply dependent on the soil.

8. The soil is always moist, and when many roots of plants come into contact with the water through the flowerpot, capillarity will be formed and fed back to the soil in the inner pot. And the soil in the inner basin can also be connected with the wet layer to obtain water, so that the soil will not be too dry even if it is not watered.

9. It is convenient to observe the root system and take out the inner plate to observe the growth of the plant root system. Compared with the traditional planting, it will not cause damage and is convenient.

10. Micro-convection in the basin, because the specific heat capacity of water is obviously larger than that of soil, and there is a long-term temperature difference between the inner basin and the outer basin, forming a weak air flow, which is beneficial to the respiration of plant roots.

11. To alleviate the situation of fertilizer damage and seedling burning, the moisture in the moist layer comes from the natural volatilization of water. as the distilled water with the highest water potential, when the plant root loses water due to the high concentration of soil solution, the root water potential decreases, and the relative water potential difference between the moist air layer and the root system increases, which is due to the existence of the water potential difference, so that the moist layer can significantly supplement the water lost by the root system during hypertrophy and root burning. As a result, the phenomenon of fertilizer damage and seedling burning can be avoided or significantly improved, which is shown by the obvious improvement of fertilizer tolerance of potted plants.

Based on the characteristics of the wet pot structure, there are several processes when using this flowerpot. When the root system has not broken through the inner pot, it basically needs to be managed like ordinary potted plants. In addition, the outer pot should be injected with water, which only has the advantages of item 3, 6 and 10. Should not be taken lightly at this time.

When the root system breaks through the inner basin and enters the air layer, it increases the 2nd and 11th advantages.

When a large number of roots come into contact with the water surface, the advantages of items 1-11 can be fully demonstrated. If there is enough water and fertilizer in the basin, the plant can continue to grow even if it has not been cared for for a long time.
