What are the disadvantages of traditional agriculture?

Farmers have been described by writers as "facing the loess and facing the sky" since ancient times. The Xialiba people who deal with mud all day are dirty and tired at work. But modern farmers will face all kinds of advanced instruments and tools, control satellites and operate computers.

Farmers have really become the "masters" of the land, not the "slaves" of the land.

In the clean operation room, farmers only need to press different buttons, and the combine can harvest corn. Because of the use of a system combining global positioning satellite and computer to engage in "precision agriculture" farming, the monitor calculates the yield of each corn during harvesting, and the GPS receiver accurately records the position of each corn, and the result is the yield map of this land. Before sowing after harvest, the soil sampler inputs the soil data into the computer, and the GPS receiver records the sampling position and draws the soil map. The computer compares the yield with the soil map, and then fertilizes and sprays drugs according to different requirements through the sprayer controlled by the global positioning satellite system.

One of the biggest shortcomings of traditional irrigation technology is that crops can only be irrigated passively. These crops are more pitiful than babies who can't talk. When babies are full of milk, they turn their heads and refuse to eat any more, but these crops cannot express themselves. They often drink too little water or too much water. At present, scientists are helping crops "learn to drink water". It turns out that plants have great ability to absorb water from soil. When water is scarce, this suction will destroy the water column in the crop stem. Therefore, scientists use this characteristic of crops to connect plants with computer-controlled irrigation systems, so that plants can "decide" when to turn on the tap. The same is watering. This method not only saves water, but also saves time and effort. The most important thing is to let the crops "drink water" themselves. Isn't this more conducive to their growth? Of course, robots are indispensable to agriculture. It can be called "new farmers".

With the rapid growth of the world population and the rapid development of the global economy, traditional agriculture has come to an end, and only advanced science and technology can find a way out for agriculture.
