Rapid Soil Moisture Temperature Analyzer Analysis of Advantages of Corn Dryland Coating Technology

Covering cultivation techniques can improve the hydrothermal status of the plough layer, increase the utilization of water resources and the yield of crops, especially in arid regions, and its role is considerable. Previous studies have focused on the effects of cover cultivation on soil moisture, temperature, nutrients, biomass, and crop physiological characteristics and yield from a single perspective, but have produced full-film double-furrow planting in cover cultivation, especially in semi-arid areas. There are not many research reports on the comprehensive effects of soil water and heat, production, and sustainability. The mechanism of yield increase is still unknown, and it needs further study. This study was to study the comprehensive effects of soil moisture and heat production and yield increase of maize cultivation in dry land, and to elucidate its influence mechanism on the changes of soil water and heat environment, and provide theoretical basis and technical support for high yield and stable yield cultivation of dry farming maize. For the relevant data of soil moisture, a rapid soil moisture temperature instrument was used for the determination.

Through the rapid soil moisture measurement, it was found that the "warming up theory" of dry film mulching cultivation indicated that mulching can significantly increase the soil temperature in the early growth stage of crops, and promote the early emergence of crops, seedlings, seedlings, and seedlings. The positive effect of the warming effect of the cover cultivation is due to the different diurnal and seasonal characteristics of the different field cover treatments, the different soil depths, and the different effects on the crop growth and development. In the study, there are also reports that the effect of mulching film coverage under winter low temperature and short days of sunshine is not as good as straw coverage. Therefore, choosing the optimal coverage method according to the climate type is the right way to effectively exert the effect of covering warming.

The rapid soil moisture temperature instrument measured the moisture content of the corn field under the plastic film. It was found that the mulching film in the dry land improved the moisture condition in the top soil of the corn, and the soil moisture in the 0}20 cm soil layer could receive rainfall at the end of the rice growth period. Recharge, corn growth and development of the soil water consumption is mainly concentrated in the 20-100cm soil layer. The efficient regulation of soil moisture under cover cultivation requires in-depth research.
