1. Advantages:
1. Wind can spread pollen and plant seeds, helping plants pollinate and reproduce.
2. Wind power is a clean energy source. Wind installations have become more advanced, mass production has reduced costs, and in the right places, wind power is now cheaper than other generators.
2. Disadvantages:
1. Spread of pathogens and spread of plant diseases. High-altitude winds are the weather conditions that allow pests such as armyworms, rice leafhoppers, rice leafrollers and migratory locusts to migrate long distances.
2. Strong winds also cause soil erosion, shift sand dunes and damage agricultural land. Indiscriminate reclamation of drylands will lead to land desertification due to wind. The windsHeavy rains and snowstorms in pastoral areas can disperse herds and worsen frost damage.
Detailed information
Wind is a natural phenomenon on Earth, caused by the heat of solar radiation. When the sun shines on the Earth's surface, different parts of the Earth's surface are heated differently, resulting in temperature differences that cause convective movements in the atmosphere to form winds. Wind energy is the kinetic energy of the air. The magnitude of wind energy depends on wind speed and air density. Global wind energy is approximately 2.74 x 109 MW, including 2 x 107 MW of available wind energy, or 10 times the total amount of hydropower that can be developed and used on Earth.
The kinetic energy formed by the air flow is wind energy. Wind energy is a form of cosolar energy inverted. Solar radiation causes uneven heating of the Earth's surface, causing uneven distribution of pressure in the atmosphere, causing air to move in the horizontal direction and the formation of winds. Wind formation is the result of air movement.

Advantages:
1. propagation Pollen and plant seeds help plants pollinate and reproduce.
2. Wind plays an important role in improving the environment of agricultural land. The air flow forms wind, which transports and exchanges carbon dioxide, oxygen, heat, etc. in the air. Create conditions conducive to crop growth.
3. Wind power is a clean energy source. Wind turbine installations have become more advanced, mass production has reduced costs and, at the rights places, wind power is now cheaper than other generators.
Disadvantages:
1. Disadvantages of wind energy for agriculture. Wind actually plays a dual role in agriculture. It can spread pathogens, spread plant diseases, cause crop failure, break trees, drop flowers and fruits, etc., thereby harming production and people's lives.
2. Strong winds also cause soil erosion, shift sand dunes and damage agricultural land.
3. Indiscriminate reclamation in drylands will lead to land desertification due to wind. Strong winds and snowstorms in pastoral areas can disperse herds and worsen frost damage.
Detailed informationForms of use of wind energy:
The main form of use of wind energy conassists in converting the kinetic energy of atmospheric motion into other forms of energy. Wind moves air horizontally. Air movement is mainly caused by the different intensities of solar radiation received at different latitudes of the Earth.
At the equatorIn areas at low latitudes, the altitude angle of the sun is large, the duration of sunshine is long, and the intensity of solar radiation is strong. The ground and atmosphere receive more heat and the temperature is higher in high latitude areas, the altitude angle of the sun is higher. small, the sunshine time is short and the ground and atmosphere receive heat. Low temperature.
This temperature difference between high and low latitudes forms an atmospheric pressure gradient between northern and southern China, causing horizontal air movement.
