Regarding plant protection, what is plant protection

As long as it doesn't break.

Each plant will protect itself in its own unique way through its own different forms and characteristics, such as:

1. There are thorns on the peduncle of the moon.

2. The leaves of nettles are covered with poisonous prickly hairs.

3. The leaves of the lycium are thorny.

4. Roses and amaranth have thorns on their bodies.

5. Gently touch the mimosa, it will look like a shy little girl.

6. Eucalyptus, oleander, and tomatoes emit a special smell during their growth, and so on.

The most dense spine of a plant is often the youngest part of the body, which grows before insects multiply to ward off their damage.

Plants have different ways to protect themselves: for example, there are thorns on the peduncles; The leaves with nettles are covered with venomous stinging hairs; spine of the bony lobes; cacti and so on.

1. There are thorns on the peduncle of the moon.

2. The leaves of nettles are covered with poisonous prickly hairs.

3. The leaves of the lycium are thorny.

4. Roses and amaranth have thorns on their bodies.

5. Gently touch the mimosa, it will look like a shy little girl.

6. Eucalyptus, oleander, and tomatoes will emit a special smell during growth.

Roses, with thorns on their bodies, are a way to protect 1

And the mimosa, if you touch it gently, it will look like a shy little girl, and that's also a way to protect yourself

It refers to the use of integrated measures to protect plant health, improve yield and quality, and reduce or eliminate pests, weeds and other undesirable organisms. Plant protection is an important part of the agricultural production process, which aims to ensure the normal growth and development of crops, improve the yield and quality of crops, and protect the ecological environment and human health.

Explanation and methods of plant protection:

Plant protection includes prevention, diagnosis, monitoring, and management. Among them, prevention is the most important link, including the use of biological, physical, chemical and other means to reduce the possibility of pests and diseases. Diagnosis is to identify and classify diseases, insect pests and other problems in order to take correct control measures.

There are many ways and means of plant protection. In addition to traditional chemical pesticides, biological pesticides and other means, there are also the use of natural enemies, antagonists, traps and other methods for biological control, the use of cover, light, temperature and other measures for physical control, and the use of tillage system, intercropping, crop rotation and other measures for agronomic control and other methods, these means are to achieve the purpose of plant protection.

Plant protection not only protects the growth and development of crops, but also protects the natural ecological environment and human health. For example, the excessive use of chemical socks to detect pesticides in agricultural production will cause pollution and harm to soil, water, air, animals and plants, etc., while biological control and agronomic control are more environmentally friendly and sustainable, which is conducive to protecting the environment and the healthy development of the ecosystem.

1. Protect the ecological environment and prevent land desertification.

2. Establish a management system for nature reserves suitable for the construction of the ecological environment at this stage.

3. Treat natural ecological resources correctly and implement a green economy.

4. Advocate green consumption and save material resources.

Most of the above content is basic policy information).

5. In fact, as long as we start from ourselves, take care of the environment, do not use disposable items, and protect plants.

Plants convert solar energy into chemical energy through photosynthesis and store it in plants for use by humans and other animals. Maintain water sources and maintain the natural circulation of water bodies to reduce drought and flooding. Regulate the climate, prevent soil erosion, and mitigate natural disasters such as mudslides and landslides.

Protect the environment, purify the air and monitor pollution. It provides opportunities for human society to adapt to natural changes and raw materials (selection value), etc. Maintain the sustainable use of biological species and ecological balance.

Question 1: Give an example of how we can protect plants Protecting plants is part of the round skin of caring for nature, and protecting plants is protecting our environment. You can start with the small things around you.

If you don't trample on the lawn, don't damage the flowers and trees. Promote the benefits of protecting plants. You can also learn more about plants and enhance your interest in caring for plants.

Not only do you learn by yourself, but you also have to influence others to learn together. You can also grow some flowers by yourself, which not only beautifies the environment, but also improves your plant knowledge. These are concrete actions to protect plants.

Question 2: How should we take care of plants? Protecting the environment, this is of great significance to control pollution, such as finding out whether there is a local pollution source, reflecting to the relevant departments, and supervising the solution of the problem, which is also a social practice in the park, setting up a brand to protect the flowers and plants of the digging friends, if it is a rural area (the farmer uncle will think that this is a mallet to do), it is also a social activity.

Distribute leaflets, it is best to notify the local ** to build momentum, if you can be on TV and newspapers, mention the teacher's vision when you report it early, and you will directly get a full score.

Question 3: How should we protect rare animals and plants, please put forward two suggestions: 1. Reduce the damage to the ecological environment;

2. Reduce hunting and crack down on poaching and other behaviors;

3. Restore the damaged ecological environment and strengthen the construction of protected areas.

Question 4: How should we protect animals and plants, write three sentences to protect wetlands. Protecting forests. Take care of a flower, a grass, and a tree around you.

Take a walk in nature and you can see plants everywhere, in the park, in the grass, in the fields, on the mountain peaks... Plants are everywhere, they accompany us and nurture us.

Plants and people are very closely related, human beings can't do without them, and their failures can be very useful! The grain we eat every day is barley, and the sorghum is processed into a grain when it is processed to remove the husk. For example, the rice we eat every day is made from rice peeling, and it is indispensable every day.

Vegetables, fruits, etc. are also made by plants! The drinks we drink, tomato juice, coconut water, etc., are made from plants. Don't underestimate plants, you see!

The clothes we wear also depend on it, the clothes are made of cotton spun into cloth, the usual cover of the quilt, the bed sheets, are all ** plants. During the New Year's holidays, people always buy some flowers and bonsai to decorate their homes. In addition, trees can also photosynthesize, absorb carbon dioxide, release oxygen, bring us clean air, and prevent noise.

Plants are widely distributed, in the vast sea, in the scorching desert, but with the pollution of the environment, the survival of plants has been greatly threatened, and some plants have become extinct.

The relationship between plants and people is very close, and we must protect the environment and create a better world for plants, so that they can grow freely.

Plant protection is also called plant medicine. Cultivate senior scientific and technical talents who have the basic theories, basic knowledge and basic skills of plant protection science, and can be engaged in technology and design, promotion and development, operation and management, teaching and scientific research of plant protection in agriculture and other relevant departments or units.

In the "Catalogue of Disciplines and Majors for Conferring Doctoral, Master's Degrees and Cultivating Graduate Students" formulated and promulgated by the Discipline Evaluation Group of the Academic Degree Committee, plant protection belongs to one of the first-level disciplines in the discipline category of agronomy, and there are three second-level disciplines, namely: plant pathology, agricultural insects and pest control, and pesticide science (which can be awarded degrees in agronomy and fiber).

1. Conscientiously achieve the "three ones": make a community environmental protection publicity to the family. Take part in a white trash pick-up activity. Contribute to the protection of the community's environment.

2. Do not climb and break flower branches; Don't press or kick trees. Do not pour dirty water or garbage into the forest belt. Don't scribble on trees; Do not dry clothes on trees or flowers. Do not play or trample on the ornamental lawn.

3. It is necessary to strengthen the courage to stop uncivilized behavior. Not only should we not damage the greenery ourselves, but we should also say "no" to uncivilized behaviors that destroy the greenery and stop them in a timely and proper manner.

4、.Actively assist the property management and other departments to do a good job in the greening, beautification and purification of the community. Remove or effectively control the pollution generated in daily life, less damage to the environment, more care, build a green home, and create a better park.

5. Don't cut down indiscriminately and cherish rare species.

6. Rational planting, as little as possible use of chemical pesticides, fertilizers.

7. Introduce alien species reasonably and prudently, control air pollution, and prevent acid rain from corroding green plants. 8. Reduce chlorine emissions, prevent the ozone layer from being destroyed, and avoid direct irradiation of green plants by ultraviolet rays.
