Slogan of buying seeds

In the past, people basically grew their own fruits and vegetables. Now, the words "No seeds left" are written on the packaging bags of most fruit and vegetable seeds. Some people say that this is specially used by seed companies to make money. If farmers want to buy every year, they can make money every year, can't they? Seed companies want people to buy seeds every year, but it is also true that many crops can't keep their own seeds. Many seed companies use hybrid seeds for sale to obtain economic benefits.

Hybrid background can indeed inherit the excellent characteristics of parents, with the characteristics of drought resistance, cold resistance, pest resistance and high yield, and has many advantages compared with ordinary seeds.

Using hybrid offspring can effectively avoid the situation that farmers keep their own seeds. This is because the composition analysis of the next generation caused by hybrid seeds leads to uneven quality and poor stress resistance of hybrid species. For farmers who want to sell agricultural products, this seed has no production value.

But not all seeds will not die. Crop seeds such as carrots, spinach and garlic can exist alone. Even if the words "no self-esteem" are written on the package, individual wheat can leave its own seeds, but the yield will be reduced.

Leaving no seeds mainly depends on the use of crops. If you only eat in your own home, it doesn't matter much if you don't leave any seeds, but if you want to grow and sell agricultural products on a large scale, it's safer for Hui small farmers to go to regular agricultural stores to buy seeds.

I used to grow all kinds of crops at home. Basically, the seeds planted in the previous year were all better crops this year. However, the crop seeds sold in the market and the crops planted in the future are better than those planted at home in terms of yield and disease resistance. To this end, people have given up the habit of storing crop seeds.

But we rural people have the habit of saving! Crop seeds sold in the market are usually more expensive. Therefore, some rural people will use the seeds of crops purchased in the market to intelligently plant various crops as reserve varieties for next year. For example, my family used to make an appointment to buy rice seeds in the market after harvest. As a result, the harvest of that year was directly reduced by half, and many empty shells appeared on the rice.

Since then, my family no longer reserves the seeds of crops bought in the market. Later, we found that the packaging of crop seeds bought in the market was written with the words "No seeds" or "No more planting". Then why? Isn't the crop that grows with seeds "that son"?
