1. Soil can not only fix plants, but also affect the growth and development of flowers through the water, nutrients, air and temperature in it, so soil is the basis for flower growth.
2. The influence of soil quality on flowers is different soil types.
Effects on flower fertility In general, most flowers require growth in humus.
abundant, loosely aerated and well-drained soil.
3. The soil provides the growth environment for the roots of the plants, keeps them warm and moisturized, and can assist the roots to fix the plants. Soil is a good "storeroom" in which water, air, mineral elements can be stored, which are necessary for the growth of plants, which are ingested directly from the soil. In addition, the soil contains a large number of other organisms, such as microorganisms and invertebrates.

Learn the first lesson of gardening, starting from the understanding of soil, and take everyone to understand the role of soil on plants.

1. Crop production function: soil can fix plant roots, has natural fertility, can promote crop growth, and carry out agricultural production. This is one of the earliest recognized functions of soils, including agriculture, forestry production, food crop and cash crop production.
2. Animal and plant habitat function: for the purpose of protecting rare animals and plants, to ensure that the soil can provide habitat for plants and animals. Soils, whether as or possibly as habitats for some particular or rare species, have high conservation value.
The function of soils as habitats for plants and animals (or potential habitats for plant and animal communities) plays an important role in protecting and enhancing biodiversity.
3. Regulatory function: the function of soil as a component of nature and the interaction with other environmental factors. It includes the function of water circulation, that is, the quantity and quality of water infiltration and retention of soil in the water cycle.
Nutrient cycling function, that is, the ability to supply plant nutrients in nutrient cycling; Carbon storage function, that is, the storage function of soil for organic carbon and inorganic carbon in the carbon cycle, especially the storage function of organic carbon; Buffer filtration function, that is, the buffer filtration function of soil for heavy metals; Decomposition and transformation function, that is, the decomposition and transformation function of soil to organic pollutants.

Protection, the root system of plants will firmly grasp the soil, which can prevent soil erosion and prevent desertification; Improve the soil, the dead leaves of plants will become nutrients after decay, so as to promote the growth and development of plants; Increase nutrients, some leguminous plants have rhizobia in their roots, which can play a role in nitrogen fixation; Purifying effect, the soil also has a good promotion effect on plants, making the air more fresh and natural.
Plants actually have a good protective effect on the soil, while the plant grows and develops, the root system of the plant will firmly grasp the soil, which can prevent soil erosion, especially in the desert, can grasp the water source to the greatest extent, so as to prevent desertification.
At the same time, plants can also play a role in improving the soil, many plants after the evolution of time, fallen leaves and dead branches will fall on the soil, after a period of fermentation, will make the soil more fertile, so as to provide the nutrients needed by plants, so as to continue the cycle.
At the same time, some leguminous plants will have some rhizobia in the roots, which grow and develop in the soil for a long time, which can play a role in nitrogen fixation, which can improve the acidity and alkalinity of the soil, make other plants grow more luxuriant, and greatly improve the nutrient content of the soil.
At the same time, the soil also has a good protective effect on plants, and plants absorb carbon dioxide in the air and release oxygen in the case of photosynthesis, which can provide nutrients and water needed for plant growth, and can also play a good auxiliary role in greening, making the air more fresh.

In the process of plant growth, the soil mainly plays four roles: 1. It plays a supporting role, so that crops can be more easily exposed to the light source; 2. Provide water and oxygen necessary for crop growth; 3. Provide nitrogen, phosphorus, potassium and other nutrients; 4. It plays a buffering role for high concentration of nutrients and dense microorganisms.
The supporting role of the soil.
It provides mechanical support for green plants to take root and sprout in the soil, and the root system to stretch and intersperse in the soil, so as to ensure that the aboveground parts of green plants can stand stably in nature.
Supply of soil moisture and organic acids.
Soil is a granular structure composed of large and small particles such as mineral particles and soil organic matter, and water and air are held in the crevices of the particles. The interstitial water and air in the soil aggregate structure can be utilized by crops.
It is important to maintain a moderate amount of moisture and air between the particles of the soil, and to drain well and at the same time adequately supply water. In other words, it is necessary to keep the soil loose and moist.
The supply of nutrients in the soil.
Soil species contain nutrients necessary for crop growth, and the mineral ions of these nutrients are combined with humus in the soil, and some nutrients such as K and N are easy to be lost, and some nutrients such as P, Ca, and Mg are easy to be fixed by the soil and are easily absorbed by crops. Soil also has the ability to conserve water, maintain soil moisture, and supply nutrients.
In addition to fresh animal and plant remains (coarse organic matter), there is also brown or black organic matter with a definite structure and no fixed form, which we call humus. The mineral nutrients of the soil in humus are bonded together with humic acid to form a humus complex, which can retain inorganic nutrients or make soil agglomerates, and improve the nutrient retention ability of the soil.
Clay and humus have a small particle size, so they have a larger surface area than the same volume of gravel, and a large amount of nutrients can adhere to them. Nitrogen and potassium can then be adsorbed on the surface of humus and gradually absorbed by crops. This is also the reason why soils with high humus content tend to retain water and fertilizer, while sandy soils tend to lose nutrients.
Soil can act as a buffer environment.
When the environment in which crops grow changes drastically, the soil can provide a buffer for plants: 1. The temperature change range is reduced; 2. When nutrients and pH change drastically, the soil can play a role in chemical buffering; 3. The soil can maintain a diverse microbial environment, and when the pathogenic bacteria increase sharply, it can properly buffer the damage caused by the pathogenic bacteria. For the healthy growth of crops, it is important to improve the buffering capacity of the soil.

The soil provides the environment for the roots of plants to grow. The water, air, and mineral elements necessary for plant growth are taken directly by plants from the soil.
Soil is the loose surface layer on the lithosphere where plants can grow, and it is the substrate for the life of terrestrial plants. It provides mineral elements and water essential for plant life, and is an important place for the exchange of matter and energy in the ecosystem. At the same time, it is itself the product of the interaction between the biological part and the inorganic environmental part of the ecosystem.
The soil contains a large number of other organisms, such as microorganisms and invertebrates. Microorganisms can decompose organic matter (plants cannot directly absorb organic matter) and turn it into inorganic matter that plants can directly use, providing nutrients for plant growth; Invertebrates, such as earthworms, can achieve the purpose of turning the soil through their physiological effects (exercise, etc.), so that the soil void is enlarged, and the air content is increased, and the earthworm manure can provide direct nutrients for plants.
Soil is the basis for plant growth and development. The ability of the soil to supply water, fertilizer, gas and heat needed for the normal growth and development of plants is called soil fertility. These conditions of the soil affect each other and restrict each other, such as more water, the soil has poor aeration, less organic, and easy to lose; On the contrary, the soil moisture is too low and cannot meet the water needs of medicinal plants.
At the same time, due to the strong activity of aerosic bacteria, the organic matter of the soil decomposes too quickly, which will also cause nutrient insufficiency. All kinds of plants have certain requirements for soil pH. Most plants are suitable for growing on slightly acidic or neutral soils.
Plant growth and development need to be nutriently guaranteed, and nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, boron, zinc, molybdenum and other nutrients need to be absorbed from the soil, especially nitrogen, phosphorus and potassium. In the cultivation process, attention should be paid to balanced fertilization, and at the same time, attention should be paid to the use of farmhouse fertilizer to facilitate soil improvement.

Summary. Hello, I have helped you find the result: soil is a natural substance composed of organic matter below the surface, which is the cornerstone of the ecosystem and the foundation of organic farming.
There are three main uses of soil:1Agricultural Production:
Soil provides nutrients for the cultivation of a wide variety of plants and is the foundation for the growth of crops. 2.Environmental Protection:
Soil has the functions of regulating soil erosion, controlling flooding, fixing bedrock and plants, etc., and can resist the invasion of natural disasters and improve the climate and environment. 3.Other uses:
Soil can also be used as a building material, such as to make concrete and bricks, and can also be used to landfill to dispose of large quantities of toxic and harmful waste materials. In addition, soils have the role of maintaining ecosystems, supporting the survival of a large number of biological species, as well as providing nutrients for plants and other organisms, as well as absorbing and processing microorganisms.

I don't know if it's important But you can only say that they are all equally important, but because they are related to the physiological characteristics of plants, it is not and does not exist that no one is important, it can only be said that they promote each other, and what I said downstairs is also very right, Nitrogen, phosphorus and potassium are large elements, but the role of trace elements is also equally important, and you should know the barrel effect, if plants grow normally, the nutritional physiology of plants must be reasonably matched in order to reproduce normally, for example, for example, nitrogen and phosphorus, these two nutrients The role of nitrogen is to lay the foundation for the reproductive growth or normal growth of plants, but phosphorus can promote germination, which is why sometimes when phosphorus fertilizer is applied at the time of sowing, it can improve germination rate and germination potential, and there is potassium underneath, and its role can improve the plant's ability to adapt to the environment. For example, adversity, pests and diseases, mechanical damage, and many others, but it doesn't mean that these three important trace elements are the same, and each nutrient has a specific function, and no one is important or who is not. There was an experiment in which I used a nutrient for a long time, and the result was that the plant died, and the reason was very simple, poisoning.
Plants and animals have an associated relationship with the soil. Because both plants and animals live in nature, the "spatial chain" connects plants and animals. Together with abiotic factors such as water, soil, temperature, sunlight, air, etc., the biosphere on the earth's surface is formed. >>>More
