Grow flowers to choose the right soil, 1 minute to learn to distinguish the acidity and basicity of the soil!

Judging the acidity and basicity of soil is the skill that every green friend wants to get to provide potted flowers with mutually repulsive soil acidity and basicity. Do you think your flowers will still grow well?

Here are some of the most commonly used methods of judgment.

1. According to plants

First of all, the acidity and basicity of the plants growing in the soil can be judged.

The editor summarized the flowers and plants suitable for growth in acidic soil and alkaline soil respectively.

Acidic soil: rhododendron, camellia, tea plum, red maple, magnolia, Milan, gardenia, pearl orchid, begonia, Davidia involucrata, golden flower tea, potted orange, cherry blossom, five-needle pine, Luohan pine, and most foliage plants.

Alkaline soil: pomegranate, elm leaf plum, oleander, forsythia, wood incense, Chinese wolfberry, hibiscus, seaside hibiscus, wisteria, Yingchun, clove, du pear, acacia, paulownia, fig, Tamarix, black pine, apricot, pear, rose, dragon cypress, week cypress, fairy ball, Platycladus orientalis, torch tree and so on.

Second, according to the source

According to general experience, humus soil from forests, mountains and valleys is mostly dark brown, relatively loose and fertile, and its permeability is also very good. It is an ideal acid humus soil, such as pine needle humus soil, peat humus soil and so on.

Third, according to the color

Generally, the darker soil is acid soil, and most of them are dark brown. However, the color of alkaline soil is mostly white, yellow and other light colors. In some saline-alkali land, the surface of the soil is often covered with a layer of powdered alkaline substance. Therefore, we can also roughly judge the acidity and basicity of the soil.

4. According to the texture

The texture of alkaline soil is very hard and easy to agglomerate, so when using it to cultivate flowers and plants, the water permeability is also very poor. The selected quality of acid soil is loose, and the ventilation and permeability is also very strong.

According to the feel of the hand

Because of the different texture of the soil, the touch of the soil must be different. Holding the acidic soil in your hand will give you a soft feeling. After releasing the hand, the soil is also very easy to disperse and not easy to agglomerate. And hold the alkaline soil in the hand, there is a kind of hard feeling, after release, it is very easy to agglomerate, and it is not easy to spread out.

6. According to the watering reaction

Watering acid soil, we will find that its infiltration is relatively fast, there is no white bubble, and the water surface is relatively turbid. However, after watering the alkaline soil, its infiltration is relatively slow, the water surface appears white foam, at the same time, there will be a layer of white alkaline substance on the periphery of the flowerpot.

7. According to the test paper

It is reliable to use PH test paper to judge the acidity and basicity of soil.

First of all, some soil samples are soaked in cold boiled water, part of the test paper is immersed in the soaking solution, and then taken out. Observe the change of its color, and then compare the test paper with the colorimetric card. if the pH value is 7, the soil is neutral; if the pH value is < small, it is acidic; if the pH value is > 7, it is alkaline.
