Problems solved by technology

Although rice is a crop resistant to continuous cropping, since the production of organic rice cannot be controlled by chemical agents, long-term continuous cropping will also lead to the accumulation of pathogenic bacteria in the field and increase the density of insect populations. To control the occurrence of pests in the field, various methods such as soaking seeds in Chinese herbal medicine liquid and preventive spraying of botanical pesticides are used to prevent and control pests and diseases. Severely reduced yield, even cultivation failure
