Why do most plants adapt to grow in soil?

Soil is just one of the media that meets the above three plant growth conditions, and the principle of soilless cultivation technology developed in modern times is to meet the above three conditions of the medium to cultivate plants and replace soil, for exampleAsbestos, vermiculite, etc. In nature, only soil is the most widely distributed and most common medium that meets the above three conditions, so most plants grow in soil.

The soil contains a large number of trace elements that are required by plants.

Plants can absorb the organic components of nature through their own instinctive structure to complete the normal growth process of plants. If humans can provide the environment that plants need to grow, plants can still grow without growing in the soil.

In our layman's terms, no matter what the environment, there must first be a producer of nutrients, and then there must be predators.

Moreover, there are far more makers than marauders in order for marauders to survive. And plants are the makers of this, and when you say that plants are mostly suitable for growing in the soil, you mean plants that we can see with the naked eye.

The vast majority of plants grow in soil because it contains water and minerals that are necessary for plant growth. Plants absorb water and minerals through their thick and thin roots, which are then supplied to all parts of the body. At this time, the root of the plant resembles its "mouth".

In some arid places, water is found deep underground. The roots of the plants there tend to be very long, reaching deep into the soil to "drink" water. Solid soil allows plants to take root.

At this time, the roots are like the "feet" of the plant, grasping the soil and helping the trunk to stand up straight, so that it will not be blown down by wind and rain.

There are two main types of plant roots, one of which has a particularly thick taproot, while the other type of root is about the same length and thickness, like a whisker. Soil culture is actually a new type of cultivation technology that uses an artificial root environment to replace soil. Soilless cultivation has many advantages.

First of all, it avoids the accumulation of pest and disease residues and salinity in the soil, so crops are not sensitive to pests and diseases. Soilless cultivation does not require heavy labor such as tillage, fertilization, and weeding, which can save a lot of manpower, time and agricultural machinery. Because soilless cultivation does not apply manure and urine, does not use sewage, and does not use a large number of pesticides, the vegetables it cultivates are pollution-free.

On the other hand, because soilless cultivation is not affected by natural conditions, it can be produced all year round and realize automatic operation, so it provides the possibility of factory production of agricultural products. People also apply soilless cultivation techniques to the cultivation of flowers, especially on balconies, which can grow vegetables and flowers, providing conditions for the development of home farming.

Because the soil is very rich in nutrients, and the soil can also provide a lot of nutrients for these plants, most plants live in the soil.

Because plants need to meet three conditions for growth, sunlight, water, and air, and the soil contains a large number of trace elements, food can be absorbed.

Because the fertility in the soil is relatively sufficient, it can ensure the normal growth of crops, and then can increase the yield of crops.

Because these plants can absorb a nutrient they need in the soil, they will grow in the soil.

Our most common plant cultivation substrate is soil, the growth of most plants is inseparable from the soil, even if some plants can be hydroponic, but usually the growth of plants protected by hydroponics is always not as good as soil culture.

Soil is the main material basis for the survival of plants, which can provide the necessary water, fertilizer, heat and gas for the growth of flowers and plants, mainly because the composition of soil includes organic matter and minerals.

Soil air and soil moisture, minerals are the most basic substances that provide a variety of nutrients to plants. Organic matter can not only provide nutrients to plants, but also play a very important role in improving the aggregate structure and physicochemical properties of soil, as well as water supply, water retention, temperature stabilization, ventilation, etc.

Soil moisture is essential for plant growth and growth, and soil air is the oxygen needed by plants to learn absorption and microbial life activities**, and it is also a necessary condition for the further weathering of minerals in the soil and the release of nutrients from the conversion of organic matter.

Relevant scientific experiments have proved that the soil suitable for plant growth, if calculated by volume, organic matter accounts for about 12%, minerals account for about 38%, soil moisture and soil air account for about 15% to 35% respectively, it is reported that when plants grow, the most suitable amount of water accounts for 25% of the soil volume, and the air accounts for the same.

<> some flower friends in the maintenance of plants, a long time does not change the pot and soil, the physical and chemical properties of the soil deteriorate, which is also lacking in nutrients, water permeability and aeration are relatively poor, continue to use the plant will grow poorly, less flowering, yellowing leaves, some even do not flower, so if you want to raise a good plant, you must pay attention to replacing the soil after a long time.

Garden soil (vegetable garden soil, pastoral soil).

Also known as top-ripened loam, it generally refers to the soil used to grow vegetables and fruits in the vegetable garden. Advantages: due to frequent fertilization and tillage, the fertility is high, the aggregate structure is good, and it is neutral, slightly acidic or slightly alkaline.

It is the main raw material for the preparation of culture soil. Disadvantages: The surface layer of the soil is easy to compact, resulting in the evaporation of soil moisture and the decrease of oxygen content, and it is easy to cause water accumulation in the pot, which affects the respiration of plant roots.

It is definitely not possible to use it directly to raise flowers. Usage: It can be used as a flower bed or prepared culture soil, and when cultivating plants, it is necessary to cover the surface with other loose and breathable soil media.

It is suitable for planting jasmine, sunflower, triangular plum, chrysanthemum and other plants with tenacious vitality.

Humus. It is also called leaf soil, which is made by using various plant leaves, weeds, etc. mixed with garden soil for fermentation, and after full fermentation, it can be used by drying in the sun. Pros:

It contains a lot of organic matter, loose and fertile, has good air permeability and drainage, and has a slightly acidic pH. The high temperature in decomposition and fermentation can kill the germs, insect eggs and weed seeds, etc., and reduce the harm of diseases, insects and weeds. Cons:

The production occupies a large area and the fermentation cycle is long. Usage: General humus can be used with garden soil and mountain mud.

It can be used to cultivate orchids, orchids and cyclamen. <>

Landslides. This kind of soil is commonly known as orchid soil, which is formed by mixing with the topsoil of the mountain soil after the leaves fall in the mountains, and the difference between the humus soil and the humus soil is black soil, and the mountain mud is loess. It is good potting soil.

Advantages: loose soil, acidic. The texture is relaxed, not only breathable, drainage, but also water and fertilizer retention, and the soil contains high organic matter.

Disadvantages: Compared with humus, the texture is more sticky and heavier, and the humus contains less, and the nutrients are not as good as humus. Usage:

It is often used for cultivating orchids, azaleas, camellias, osmanthus, etc., which like acidic soil, and can be used as stump bonsai cultivation soil. <>

Pond mud is a sedimentary soil that has been deposited on the bottom of a pond or lake for many years, and its color is gray and black.

Advantages: Contains decaying and decomposed aquatic animal and plant remains and excrement, rich in organic matter, sufficient nutrients, well drained, neutral or slightly acidic. Cons:

Climate affects water quality, and soil needs to be replaced every 1 2 years. And it will have a peculiar smell when placed indoors, which is not suitable for indoor planting. Usage:

Generally, in autumn and winter, dig out the pond mud or silt, dry it and break it by hand. Pond mud can be used alone or mixed with coarse sand, mixed ash or other adjuncts and is the main cultivation mechanism in South China. It is often used as soil for the cultivation of orchid and white orchid.

After being mixed with yellow clay in half, it can be used as soil for the cultivation of aquatic flowers such as lotus and water lily. <>

1. Sandy soil.

It is suitable for planting toon, cactus, aloe vera, sand jujube, lentils, grapes, salix, camel thorn, poplar, eucalyptus, sedum, desert rose.

Pineapple and other arid areas, tropical plants, or spring orchid, Mo orchid, Hui orchid, Cattelan, Dendrobium orchid.

Epiphytes such as vanilla and phalaenopsis.

2. Clayey soil.

You can plant lotus, lotus, and banyan trees.

Bauhinia, rice and other plants. Because the clay soil particles are small, the water and fertilizer retention ability is strong, and the water seepage rate is slow, these plants will grow better in such a soil environment, and the root system can be protected to meet the needs of the soil. Among them, the root system of the bauhinia and banyan trees sprouts, and the clayey soil is conducive to rooting.

Lotus, lotus and rice seep slowly in clayey soils and retain water well.

3. Loam. Suitable plants include camellias, cannas, and moon flowers.

Pothos, osmanthus tree, lily bamboo, lemon, bird of paradise, monstera, impatiens, jasmine.

Spider plants and lilies.

and other clay soils, sandy soil is suitable for species, suitable for growing ornamental plants and various crops.

The properties of three types of soils

The properties of sandy soil: high sand content, coarse particles, fast water seepage, poor water retention performance, and good aeration performance. Sandy soil can be divided into gravel sand, coarse sand, medium sand, fine sand and silt according to the different particle content.

The properties of clayey soil: low sand content, fine particles, slow water seepage, good water retention performance, poor aeration performance.

The nature of loam: it has the advantages of clay and sand, good aeration and water permeability, water retention and thermal insulation performance, drought and waterlogging resistance, strong stress resistance, wide adaptability, long cultivation period, easy to cultivate into high-yield and stable yield soil, and is also an ideal agricultural soil.

1. Soil is used as a medium for the growth and fixation of plant roots;

2. Soil can provide mineral elements for the growth of plants;

3. There are many microorganisms in the soil, which can decompose the corpses, excrement, litter and leaves of animals and plants, and decompose them into small molecule absorbable components for plant utilization; In addition, there are some bacteria that form a symbiotic relationship with the root system of plants, which is conducive to the growth of plants;

4. Compared with hydroponics, loose soil is conducive to root respiration, thereby promoting the absorption of nutrients by roots.

Hello, if the soil is completely unsuitable for plant growth, you can carry out soil remediation. Soil remediation methods: soil remediation is soil improvement, soil remediation:

It is the addition of soil elements, organic matter, etc. to the soil. Such as natural fertilizers (organic compost), peat soils, or chemical fertilizers, these soil modifiers improve their ability to support plant life. Qi Shu.

There are many reasons why plants grow in the soil.

First of all, soil is the foundation of plant growth, which contains the nutrients and water needed by plants, which can provide a good environment for plants to grow.

Secondly, there are microorganisms, fungi, earthworms and other organisms in the soil, which can work together to build a complex soil ecosystem, which can help delay the soil to improve soil structure and quality.

In addition, the sun's light and climatic conditions also affect the growth of plants. In general, soil nutrients, water, organic matter and other elements and natural environmental factors are the key factors affecting plant growth.

Soil is the foundation of plant growth, which contains water, nutrients, and air, which are necessary for plant growth, among other things.

1.Nutrients in the soil: The nutrients needed for plant growth come mainly from the minerals in the soil. These minerals, when dissolved in water, can provide the necessary nutrients to the plant.

2.Water: Plants need water for photosynthesis, and water can also provide oxygen in the soil so that the plant's roots can breathe.

3.Temperature: Plants need to be grown at the right temperature. If the temperature is too high or too low, the plant may be harmed or stop growing.

4.Light Divine Land: Plants need light to photosynthesize, which makes food and energy.

In conclusion, soil provides the environment necessary for plants to grow, including nutrients, water, temperature, and light. These factors interact so that plants can grow and flourish in the soil.

The soil is weathered from rocks, and microorganisms enrich the inorganic salts in the orange yard, and then the plants are iterated and then use these substances vertically to synthesize nutrients for their own growth. The above-ground part is just an extension of the underground part.
