Problems solved by technology

[0003] The main reasons for the problem are as follows: 1. The growth of population, the increase of demand, in order to increase the yield, the unrestrained application of chemical fertilizers and pesticides; 2. The lack of organic matter in the soil, the harm of pests and nematodes to crops is becoming more and more Obviously, farmers increase the amount of pesticides to kill pests, entering a vicious circle; 3. The rapid development of industry leads to the discharge of a large number of three wastes, which aggravates soil degradation
