Multi-point Soil Temperature and Humidity Recorder to Analyze the Impact of Film Coverage

Film-covering cultivation methods and green fertilization, because of the effect of hot water film, green manure forms a layer of physical isolation, hindering the heat exchange and heat absorption effect between the top soil, to a certain extent, resulting in mulching and green fertilization cultivation The phenomenon of the greatest difference in surface soil temperature and contrast between soils and soils can be known from the related measurements and analysis of multi-point soil temperature and humidity recorders.

There were significant differences in soil temperature and control in the four layers (0-5,>5-10,>10-15,>15-20 cm) of plough layer in the mulching and application of green manure cultivation methods and plastic film mulching cultivation methods. The multi-point soil temperature and humidity recorder found that the difference between the soil temperature and the control in the cultivating methods of applying green manure was not covered by plastic mulching, and the cultivation methods of applying green manure and mulching film were significantly different.

The above reasons are mainly caused by the harvesting of green manure, and then the ridges are buried in the soil tillage layer of 10-15cm in the soil because the green manure is a living plant and contains more water. The results of comparison of soil temperature and humidity recorders at four soil layers in different cultivation methods showed that the difference between the mulching and the application of green manure and common cultivation methods was the most obvious, followed by the mulching method. The green manure cultivation method is the smallest.

Using a multi-point soil temperature and humidity recorder to analyze and analyze the above-mentioned various situations, the application of green manure cultivation method, because the spring drought is low temperature, and the green manure is 10-15 cm in the surface layer of the soil, but it is not the protective function of the protective film and the plastic film. The moisture of green manure gradually evaporates, and the green manure only forms the effect of irrigation and straw mulching, resulting in the phenomenon that the soil surface temperature and contrast of the manure applying fertilizer model are less different.
