China has always been a large agricultural country. Research on agriculture has continued from one of its past. Agriculture is the foundation of everything and is the promoter of social progress and scientific and technological civilization. Therefore, modernization also requires agricultural modernization. The most important thing in agriculture is the growth and yield of plants. If the crop is good and the yield is high, farmers will increase income. The increase in peasants' income represents an increase in the national economy. It represents a gradual increase in the pockets of the people. What are the influencing factors in the process of plant growth? At present, studies have shown that 52 factors affect the growth of crops, such as soil organic matter, soil moisture and soil temperature, humidity, root depth, illuminance, wind speed, and so on. Of course, some factors have a great influence, such as soil moisture, soil temperature, and some factors such as wind speed. So how do we study the impact of these factors on crop growth?
Effects of temperature on plant growth: Plants can grow only within a certain temperature range. The effect of temperature on growth is comprehensive. It can affect the growth of plants by affecting metabolic processes such as photosynthesis, respiration, and transpiration, as well as affecting the growth of plants by affecting the synthesis and transportation of organic matter, as well as directly affecting soil temperature and temperature. Affect the growth of plants by affecting the absorption and transport of water and fertilizers. The temperature and humidity recorder can record the temperature of the current environment in time, allowing us to have a thorough understanding of the temperature changes. Moreover, some studies have shown that the temperature difference between the nighttime temperature and the nighttime temperature is large, which is conducive to promoting the vegetative growth of plants. The high daytime temperature helps to increase the photosynthetic rate under strong light, and provides sufficient substances for growth; the lower night temperature can reduce the consumption of organic matter by respiration. In many places, greenhouses are now grown. A very favorable factor for growing greenhouses is that greenhouses can provide the temperature and humidity you want. You can put a temperature-humidity light recorder manufactured by Top Instruments in the greenhouse to keep you informed of the greenhouses. The environmental parameters are then adjusted at any time, temperature, light and humidity.
The effect of humidity on plant growth: Long-term recording data from the recorder confirms that air relative humidity or saturation difference is one of the important factors affecting plant water uptake and transpiration. When the relative humidity is small (the saturation difference is large), if the soil moisture is sufficient, the plant transpiration is more vigorous and the plant growth is better. If the air humidity is under saturation conditions for a long time, the growth of plants will be inhibited, which will result in the decrease of the grain filling rate of grains, the aggravation of the cotton bud bells, the decrease of cotton vitality and the quality of cotton harvest. Relative humidity is too small, it will increase the soil drought or cause atmospheric drought, especially in the conditions of high temperatures and lack of soil moisture, the water balance of the plant is destroyed, water does not make ends meet, will hinder growth and cause reduced production. This shows that soil moisture has a profound impact on the growth of plants. Similarly, the temperature and humidity autograph is an indispensable instrument when we study the growth and moisture of plants.
