Problems solved by technology

[0002] Rice high temperature heat damage generally refers to the young panicle differentiation stage, heading flowering stage and grain filling maturity stage, when the temperature exceeds the upper limit of the normal growth temperature of rice, it will affect flowering and fruiting, resulting in the increase of empty grain rate, reduced yield or even no harvest; so the high temperature heat damage of rice Control is very important. Rice is extremely sensitive to temperature during the budding and heading stages. The most suitable temperature is 30°C. If the daily average temperature exceeds 30°C, it will have adverse effects. If the booting stage encounters continuous high temperature above 36°C, Rice flower organs are underdeveloped, pollen is poorly developed, and the vitality is reduced; if the heading stage is exposed to high temperatures above 36°C, heat damage will occur, affecting loose pollen and elongation of pollen tubes, resulting in the inability to fertilize and form empty shell grains, resulting in a decrease in seed setting rate and dryness. Low grain weight, or even no harvest

Abstract

The invention provides an early warning device and method for rice heat injury. The method comprises a step of randomly selecting a plurality of temperature monitoring positions in a rice planting land and installing a monitoring device at each temperature monitoring position, a step of inserting soil temperature sensors and soil humidity sensors of the monitoring devices into rice planting soil,monitoring the temperature and humidity of roots of rice in real time, and meanwhile, allowing an air temperature sensor to monitor the temperature in air in real time, a step of inserting the soil temperature sensors and the soil humidity sensors into the rice planting soil, monitoring the temperature and humidity of roots of the rice in real time, and meanwhile, allowing the air temperature sensor to monitor the temperature in the air in real time, a step of comparing an average value of the acquired temperature data with a standard temperature, and a step of selecting different countermeasures according to the degree of high-temperature heat injury after comparison. According to the early warning device and method for the rice heat injury, the data acquisition is accurate, and differentcountermeasures can be selected according to the range of different acquired high-temperature data.
