Temperature measurement plays an indispensable role in the agricultural field, running through all aspects of agricultural production and having a profound impact on the growth, development, and yield of crops.
During the sowing stage, different crop seeds require suitable temperature conditions for germination. For example, corn seeds generally start to germinate at around 10 - 12℃, while the minimum germination temperature of rice seeds is about 10 - 12℃, and the optimal temperature is 30 - 32℃. Farmers can use temperature measurement to select the appropriate sowing time to ensure that the seeds can germinate smoothly. During the seedling - raising process, temperature control in greenhouses is particularly crucial. For vegetable seedling - raising, such as tomatoes and cucumbers, precise temperature control is required. The daytime temperature is generally maintained at 20 - 25℃, and the nighttime temperature is 15 - 18℃, which can promote the healthy growth of seedlings and improve the quality of seedlings.
During the growth process of crops, the monitoring of field temperature is also of great significance for the prevention of pests and diseases. Certain pests and diseases are prone to breeding and spreading within specific temperature ranges. For example, wheat rust is prone to epidemic when the temperature is 15 - 20℃ and the humidity is high. Through temperature measurement, farmers can take pest and disease prevention measures in advance. In addition, during the fruit - ripening stage, temperature also affects the quality of the fruit. For example, during the ripening period of grapes, if the temperature is too high or too low, it will affect the sugar accumulation and color. Therefore, accurate temperature measurement can help farmers optimize the agricultural production process and improve crop yield and quality.
