Problems solved by technology

[0004] The production period of crops also happens to be the period of high incidence of diseases and insect pests and the growth period of weeds. How to achieve the three in parallel has always been a research problem to be solved, because if no measures are taken, fertilizers will also play a role in promoting the growth of weeds , and during the production period of crops, the protection of crops against pests and diseases is weakened, and they are easily damaged by pests and diseases, resulting in irreparable losses
