What environmental protection measures are there?
Firstly, selecting and planting high-quality rice varieties resistant to pests and diseases is a powerful means to control pests and diseases, and it is also an important part of key measures in the integrated control system. The second is agricultural control, that is, according to the physiological and ecological characteristics of pests and the relationship between their occurrence and related agricultural factors, under the premise of ensuring non-toxic, high-yield and high-quality cultivation, combined with the improvement and perfection of various agricultural measures, the rice farmland ecosystem is regulated to achieve the purpose of controlling some pests. In the application of agricultural control technology, we should flexibly weigh and grasp the advantages and disadvantages based on the integrity and dynamics of farmland ecosystem and the interaction of related components.

Agricultural control techniques mainly include tillage and harrowing measures to improve the physical and chemical properties of soil and affect the habitat and living conditions of pests; Scientific fertilization, full application of organic fertilizer, rational application of chemical fertilizer, scientific adjustment of the reasonable proportion and dosage of nitrogen, phosphorus and potassium fertilizer, attention should be paid to avoiding blind application of nitrogen fertilizer to promote the vigorous growth of rice, so as to enhance the resistance of rice to pests and diseases and its self-compensation ability after being injured. The applied organic fertilizer should be fully decomposed, otherwise it will easily cause the harm of underground pests such as grubs; Scientific irrigation, adjusting soil moisture and farmland microclimate to make it suitable for the normal growth and development of rice can control the occurrence and harm of some diseases and insect pests; Implement reasonable close planting, establish reasonable population structure and promote rice health. In addition, artificial physical control can be carried out, that is, the egg mass of rice stem borers can be removed in time, and the dead seedlings and white ears can be removed. Where conditions permit, the moth-trapping lamp with frequency vibration can be used to trap and kill borers. Generally, setting a lamp on 4 hectares can reduce the population base.
