1. Water and water are the most important substances in the cells of plants, which can promote the circulation of substances between cells, and can also provide a certain amount of energy for the life activities of the whole organism.

2. Light and light are necessary conditions for plant survival, which can promote the normal progress of photosynthesis, ensure the synthesis of water, carbon dioxide and chlorophyll, ensure the growth and development of leaves and flowers, and the color can be more vivid and bright, and will also play a role in raising the temperature to avoid hindering the growth rate. 3. Temperature is one of the conditions to promote plant growth, temperate and tropical plants, cold resistance will be relatively weak, high temperature is needed to ensure normal growth, frostbite and frostbite will not occur, some plants have weak high temperature resistance, high temperature will lead to dormancy, growth rate becomes sluggish.

4. Air and air are also indispensable substances in the growth process of plants, nitrogen is easily absorbed by the soil, and is also easily absorbed by the roots of plants, which plays a role in promoting growth, oxygen and carbon dioxide are important guarantees for maintaining photosynthesis and respiration, and carbon can also promote the synthesis of organic substances. 5. Soil soil is the environment on which the growth of plant roots depends, with sufficient content of nutrients, minerals and humus, high drainage and air permeability, the growth of plants, and can also play a role in fixing plants, heat preservation and moisturizing, and the soil also contains a large number of microorganisms, which can decompose nutrients and ensure that the land is more fertile.

The growth of plants needs light, air, nutrients, water, temperature, soil, etc., among which light can make plants photosynthesize, and the raw materials of photosynthesis are water and carbon dioxide, which can make plants synthesize organic matter and promote their vigorous growth, and plants have a higher demand for nutrients such as nitrogen, phosphorus and potassium.

1. Light

Light is the basic need for plant survival, most of the energy and energy required by plants are obtained from sunlight, light can promote plant photosynthesis, make it synthesize organic matter, is conducive to the vigorous growth of plants, and plant leaves are important organs for photosynthesis.

2. Air

Plants need air during growth, and carbon dioxide in the air is the raw material for plants to synthesize organic matter, and oxygen allows plants to carry out aerobic respiration, which can enable them to decompose the organic nutrients stored in the body into ethanol, carbon dioxide and lactic acid through step-by-step reactions, which can maintain the normal growth of plants.

3. Nutrients

The growth of plants needs nutrients, among which nitrogen, phosphorus and potassium and other elements have a high impact on the growth of plants, nitrogen is the composition of protein, chlorophyll and nucleic acid in plants, phosphorus can synthesize proteins and enzymes required by plants, and potassium can improve plant disease resistance and lodging resistance.

4. Moisture

Plants need sufficient water in the growth, water can make the plant grow luxuriantly, provide conditions for its photosynthesis, and plants are divided into aquatic plants and terrestrial plants, aquatic plants mainly grow in water, and terrestrial plants are divided into water-loving plants and drought-tolerant plants, drought-tolerant plants have less water requirements.

Plant growth needs sunlight, temperature, nutrients, water, among which light is an important factor in plant growth, most plants like sunlight, a small number of shade-loving plants also need to be exposed to sunlight, and the temperature will affect the flower bud differentiation of plants, and the temperature is too low will lead to the death of some plants.

1. Sunshine

Plant growth needs sunlight, sunlight is the most important factor in the growth process of plants, even shade-loving plants have to receive light to grow, when breeding plants, you need to place them in a bright place in the spring, autumn and winter, and in the middle of summer, you should do a good job of shading measures for plants.

2. Temperature

Plant growth needs temperature, temperature is an indispensable factor in plant growth, because the temperature can affect the flower bud differentiation of plants, and when the temperature is too high, it will lead to the death of some plants that are not heat-tolerant, and when the temperature is too low, it will make some plants with poor cold tolerance die.

3. Nutrients

Plant growth needs nutrients, most plants grow in the soil, because the soil contains nitrogen, phosphorus, potassium and other mineral elements, which is conducive to plant absorption and growth, and some plants that can grow in water, also because the water contains the nutrients needed by plants, when breeding plants, they need to be fertilized regularly.

The growth of plants needs light, air, nutrients, water, temperature, soil, etc., among which light can make plants photosynthesize, and the raw materials of photosynthesis are water and carbon dioxide, which can make plants synthesize organic matter and promote their vigorous growth, and plants have a higher demand for nutrients such as nitrogen, phosphorus and potassium.

Plants need light, water, temperature, soil, etc. to grow. Sunlight is the basic guarantee for maintaining the normal growth of plants, which can promote photosynthesis and increase the surrounding growth temperature. Water is the most basic component of plant cells, which participates in various life activities and plays a promoting role.

Temperature can affect the growth rate of plants, and it can also change the growth form of plants.

Sunlight is the most basic guarantee to maintain plant growth, which can promote the normal progress of photosynthesis, speed up the synthesis of nutrients, and can also increase the growth temperature around plants, avoid frostbite and slow down the growth rate. However, in the process of breeding, it is necessary to do a good job of shading treatment to avoid partial burns of the leaves.

The appropriate temperature can promote the growth of plants, ensure the normal life activities of the body, will not enter a dormant state, hinder the speed of growth and development, the appropriate temperature difference between day and night, can shorten the opening time of flowers, increase the brightness of flower color, and for succulents, it is conducive to better brocade.

Water is an important substance in the composition of plant cells, it can exist anywhere in the plant body, ensuring normal osmotic pressure in the cells, and there will be no stomatal closure, resulting in atrophy, dryness, and yellowing of leaves. However, in an environment where there is too much water, it can lead to root rot.

Suitable soil environment is the key to promote the growth and development of plant roots, some plants prefer alkaline soil, some plants prefer acidic soil, only in the soil environment with high content of nutrients, minerals, humus, good drainage and air permeability, the growth rate of plants will be accelerated.

The growth of plants requires light, water, temperature, air, minerals, etc., which can promote photosynthesis and synthesize a large number of nutrients for themselves to ensure normal growth. The appropriate temperature can promote the differentiation of flower buds, speed up the flowering speed, ensure the integrity of the flower type, and make the flower color more vivid. Air is able to maintain the normal process of photosynthesis and respiration.

Different plants need different wavelengths of light to receive light, and light can promote the photosynthesis of plants, accelerate the formation of water, nutrients and oxygen, and ensure their normal growth. At the same time, light can bring heat, increase the temperature of the growing environment, and avoid frostbite in plants.

Water is an indispensable substance in the process of plant growth, which can ensure the fine and normal growth of the most basic cell structure, ensure normal osmotic pressure, and promote the transport of nutrients. Different plants have different water needs, and different growth stages have different water needs, so it is necessary to control the water content.

Temperature is to promote the growth of plants, the differentiation process of flower buds, provide sufficient heat energy, through a series of reactions, into internal energy or chemical energy, appropriate temperature difference, can also improve the speed of plant flowering, to ensure that the flower type can be complete, the flower color is more colorful, and the flowering period is extended.

The oxygen and carbon dioxide gas contained in the air can ensure the growth of plants, ensure the normal progress of photosynthesis and respiration, realize the mutual conversion of oxygen, carbon dioxide and water, and play a role in purifying the air. The humidity of the air should also be controlled within the appropriate range to ensure that the plants do not suffer from water shortage.

Minerals in the soil are the most important and nutritious nutrients for plant growth, a large number of nitrogen, phosphorus, potassium, calcium and other trace elements, can improve the content of organic matter and minerals in the soil, promote the growth of stems, branches and leaves, and can also ensure the normal blooming of flowers, accelerate the formation of xylem.
