It is said that American agriculture is advanced. Let's see how American agriculture works.

From the current impression of the Chinese people, the perception of American agriculture is basically highly mechanized and genetically modified. So specifically, is it true that American agriculture is as mentioned above? Science promotes agriculture here can say clearly, really so! Let's talk about it briefly from the above two aspects.

genetically modified corn

According to Science and Technology Daily, in the past 22 years (counting from the commercial planting of genetically modified crops in 1996), genetically modified crops in the United States have become more and more widespread and popular with farmers. It took only a few years from initial disapproval to gradual full acceptance. Now the penetration rate of genetically modified soybeans, corn, cotton and rape in the United States has reached more than 90%, and this momentum has not stopped at all.

In the future, the planting area of genetically modified crops and the types of crops in the United States are expected to increase further. Acceptance of genetically modified crops in the United States also varies widely among countries, but in the United States alone, people have diluted their views on genetically modified crops because it is difficult for supermarkets to see agricultural products without GMO labels.

The advantages for GM crops are obvious, such as easier weeding and higher yields. Weeding in corn fields is a big problem in our country. Basically, closed herbicides are used before seedling to kill weeds that are about to emerge. However, a problem that cannot be ignored is that weeds after seedling are also a major factor in corn yield reduction.

American farmers simplify the problem by growing genetically modified corn, which is highly effective at weeding at any stage of corn growth.

mechanization

This mechanization is different from the small-scale mechanization mentioned in our country. Here we can look at a set of data. The United States has 2.2 million people planting and 2.2 million agricultural products, which is equivalent to one farm per person, with an average planting area of thousands of acres. With such a large amount of farmland, how can we satisfy, cultivate and harvest without highly mechanized farming? So in the United States this mechanization is everywhere.

For example, at the harvest stage, China grows late-maturing varieties that yield higher yields because they have a longer growth period, whereas Americans seek early maturity rather than late maturity because early-maturing corn dries faster and is more suitable for mechanized harvesting. At the same time, planting genetically modified corn in large areas simplifies weeding and farmland operations.

This mechanization is not limited to this. For example, straw returning, fertilizing, spraying and watering are all completed by mechanization. In fact, what is expensive in the United States is not machinery but manpower. Sometimes it is not possible to find manpower by spending money. This is the state of America, the state of American agriculture!

There are still many differences between American agriculture and China's agriculture. For example, American summer is basically two crops, corn and soybean. When planting, they are basically rotated. This farming method avoids the continuous cropping phenomenon that often occurs in Chinese agricultural planting.

In fact, the United States is not only leading the industry, but agriculture is also at the forefront of the world. Looking at American agriculture, sometimes I have to say with emotion that the United States is the real "agricultural power".

Here is science rejuvenates agriculture, welcome to add attention, take you to grow knowledge together.
