Effect of Different Film Covering Methods on Soil Moisture of Maize

Effect of Different Film Covering Methods on Soil Moisture of Maize

Jianning County has experienced drought year after year with scarce rainfall. To ensure food production, drought- and water-saving techniques and measures have been widely used and have achieved good results, of which mulching is one of the most effective means. In order to further explore the role of mulch-covered drought and water saving, it was decided to carry out different mulching model tests on corn crops in Jianping County in order to develop the mulching model that is most suitable for Jianping County through this experiment, and to further improve the techniques of dryland and water conservation. Promote drastic development of dry farming. Our trial sites were located in the test site of Quedu town and the Agricultural Center. Each test site was set up with 5 plots: bare land, autumn cover, half cover, spring cover, and spring cover. . At the same time, soil moisture was measured in five plots of arable soil. A wireless moisture monitoring system was used to measure soil moisture. The wireless public opinion monitoring system is also called the GPRS soil moisture monitoring system, which realizes wireless transmission through GSM, radio station modules, and the like. The value of water content was used to determine which model had the best drought- and water-saving effects.

Due to the better soil moisture in autumn, the soil moisture in the spring coating is poor, and there is very little precipitation in winter. Therefore, the soil moisture content in spring on May 3 is much higher than that in the spring, and the total film and half The film is not very different. Using a multi-functional soil moisture recorder, the soil water content was greatly decreased due to the large amount of water required during the jointing stage, and the precipitation was less. From the results of determining the soil moisture content on June 25, the autumn coating was larger than the spring coating. The semi-membrane is larger than the whole membrane. Because the base value of the autumn coating is high, the half-film can absorb natural precipitation while retaining water. The numerical value of moisture content on July 23 is basically the same as the previous measurement.

1. From the numerical analysis of soil water content, it is concluded that the autumn coating is better than the spring coating, and the half coating is better than the full coating. 2. The best performing of the five modes is the fall over the half film, which not only maintains the better autumnal mood but also accepts precipitation at any time. Under the same drought conditions, this model has the highest moisture content and the highest natural maize yield. 3. To cover the semi-film in autumn, we must grasp the timing of filming, the adjustment of ridge spacing, plant spacing, and the protection of winter mulch. These will continue to be explored in the agricultural production of Jianping County to form a complete set of autumn and semi-film droughts. For water-saving cultivation techniques, serve agricultural development.
