Changes in Soil Moisture and Temperature on the Covered Mulch Membrane: Analysis of Spring Corn and Peanut Planting will use cover film to increase the temperature and humidity of the soil to meet the growing needs of corn and peanuts. There is a 0-100m soil layer of mulch land that is measured to understand the effect of plastic film on soil temperature and humidity.
In the process of operation, a control group is used to conduct the test, and a soil moisture temperature measuring instrument is used to measure different stages of corn at different stages (the current temperature mainly studies soil layers of 5cm, 10cm, 15cm, and 20cm, and soil moisture The research level is mainly the temperature and humidity changes of 0-20cm, 20-40cm, 40-60cm, 60-80cm, and 80-100cm soil moisture, which are measured and analyzed.
Through the use of temperature and humidity monitoring instrument to analyze the results of the analysis can be: whether sunny, cloudy, cloudy, rainy days, mulching film in the early growth stage of corn have a warming and heat storage effect, can improve the soil tillage temperature conditions. However, the effects of warming are different in different weathers. The effect of warming is: sunny> cloudy> cloudy> rainy. The warming effect of sunny days is the best. The effect of warming at 5cm can reach 8.43°C. The worst temperature increase effect is in rainy days, and the best temperature increase effect in rainy days is at 20cm.
The mulching film itself can increase the ability of the soil to retain water and water, accumulate natural precipitation in different periods and preserve it in the soil for the critical period of the crop, effectively promoting a virtuous circle of soil-crop moisture. The contradiction between the large amount of precipitation in the early stage of spring maize growth and the inconsistent development of maize was solved. The deeper the detection depth, the higher the soil moisture content.
From the above, it can be seen that Voldemort can increase the temperature and humidity of the soil to a certain extent. Therefore, it is advisable to use covered mulch in arid areas to increase the amount of water stored in the soil. This can reduce the impact of insufficient rainfall on crops. loss.
