There are a large number of plants growing on the earth, and they have a crucial impact on our human existence. Provides us with food, oxygen, etc. Green plants are very important to us and we should learn how to protect and use them.

Photosynthesis of plants is to absorb energy from sunlight to synthesize organic compounds such as starch. Humans can obtain food through green plants, and it is because of the existence of plants that other life on earth can survive and multiply. Plants can adjust the carbon and oxygen balance of the air. Garden plants in urban green spaces absorb carbon dioxide in the air through photosynthesis, making our air fresh.

To protect green plants, first of all, it is necessary to plan rationally, delimit the development area of ​​green plants, and gradually expand the area of ​​green plants. The second is to strengthen fertilizer and water management, apply enough fertilizer, achieve balanced fertilization, rational water supply, and promote the growth of green plants.

In addition, it is necessary to strengthen the control of pests and diseases to ensure the healthy growth of green plants. Common plant diseases are powdery mildew, leaf spot, gray mold, rust, blight, soot and so on. Among them, powdery mildew, leaf spot and botrytis can be prevented by spraying dysenzine before the onset, and treated with carbendazim during the onset. Rust disease can be treated by spraying fenugreek, blight disease can be treated by spraying thiophanate methyl, and soot disease can be treated by spraying carbendazim.

Finally, it is necessary to strengthen management and protection to avoid trampling or destruction by humans and animals. Establish special protected areas to protect some vulnerable green plants. Arrange fixed personnel to repair protected areas to protect green life on earth.
