Problems solved by technology

[0003] The pollution-free corn is a new type of corn. This type of corn has higher nutritional value, less environmental pollution during the cultivation process, and almost no pesticides in the corn itself. It is a new type of green corn. crops, but the pests and diseases of such products are also serious, but due to the difference in products, the control of pests and diseases will also have subtle differences. If the control is carried out in an ordinary way, the effect will definitely be very poor
