I went to the organic vegetable store on the weekend. The price of organic vegetables is really not cheap. The boss explained: "These vegetables are grown without the use of pesticides in the whole process. If nothing else, weeding alone costs a lot of labor costs a year." It makes sense, I hear it again and again.Recalling that when I was a child, I went to help out in the fields on my off days, and the most I did was weeding. At that time, it was all manual operation, with a hoe and hand pulling, and the weeds had to be pulled on a sunny day, so that the pulled grass would be killed by the sun quickly and would not come back to life. A person, working hard, can't do an acre of land in a day.
Gradually, something called "herbicide" became familiar to farmers, and "herbicide", as the name suggests, is a chemical agent that can get rid of grass. When it was first used, everyone felt that it was very good. Just spray the herbicide lightly on the weeds, and it didn't take long for the weeds to die on their own. Save farmers a lot of time. But long-term use, the harm has gradually emerged. Extensive use of herbicides kills weeds, but also kills a large number of natural enemies of pests, destroying the ecological balance of farmland. The soil is compacted, which damages plant roots, penetrates into the ground, pollutes water sources, and affects health.
The use of herbicides has been gradually reduced, and other methods of weed control have emerged. "Grass-proof cloth" is a method that has been used more in recent years. Weed control cloth, also known as "grass suppression cloth", is to spread PP or PE plastic cloth on the ground to prevent weeds from growing. The advantages are environmental protection, maintaining soil moisture and increasing crop yield. The disadvantage is that the cost is high and cannot be degraded.
Artificial intelligence technology is in full swing, and many technologies have been transformed into products. The sweeping robots that are widely used by everyone, the cutting surface robots that often appear on the Internet, the installation robots that are widely used in factories, the medicine delivery robots used in hospitals, and the high-end surgical robots. If there is an intelligent weeding machine, farmers only need to set the parameters of the robot, and the weeding machine itself can remove the weeds in the field without harming the crops and polluting the land and the environment. Farmers can also be freed from the drudgery of weeding.
