Controlling Temperature and Humidity in the Environment to Prevent the Production of Rice Viruses In recent years, environmental and climatic changes caused by external factors have caused great inconvenience to the agricultural production process, including changes in temperature, precipitation, and sunlight. It has directly and indirectly affected the occurrence and epidemic of crop pests and diseases. In recent years, the occurrence of diseases and insect pests has become increasingly serious. The change of temperature and humidity in the environment has a great influence on the pathological changes of rice. This paper uses the temperature and humidity self-recording device to detect the temperature and humidity in the environment to understand the temperature and humidity changes and the changes of rice virus. influences.
Temperature is a source of heat energy to maintain the body temperature of insects. Insects can be stopped or even died due to low temperatures. By using the temperature and humidity monitor to monitor and control the temperature and humidity in the environment, it is possible to control the death, sickness, and death of the pest. As far as S. chinensis is concerned, when the temperature in the environment in January is between 4 and 20°C and lasts for 2-3 days, the mortality rate of overwintering larvae of S. indica can reach 95% or more. At this time, it is the best time to eradicate SBPH, but with the continuous increase of CO2 emissions in recent years, the temperature is increasing continuously. It is estimated that if the amount of CO2 emitted is emitted at the above speed, then it is expected to be 300. After the year, most of the larvae of S. japonicum will survive, directly affecting rice yield.
However, at high temperatures, it is detrimental to the growth of this pest. Above 35°C, adult ecloses are often malformed and larvae cannot hatch. The temperature of paddy fields lasts for more than 35°C for several days, and the larval mortality rate can reach 80%-90%. It is possible to monitor the temperature and humidity in the environment by using a temperature and humidity recorder to understand whether or not the change in temperature affects the IIC.
Although the high temperature has a certain degree of control for the pupa, but for the other diseases, the high temperature is to promote their growth, rice sheath blight is a disease of high temperature and high humidity, when the temperature reaches 22 °C or more, When the humidity reaches 90%, rice sheath blight will break out. At this time, self-reporting thermometers and hygrometers were used to measure and carry out appropriate factors in the control environment to avoid the occurrence of rice sheath blight.
