The Study Of Precision Hardware And Software Technology Of Drip Irrigation System For Wine Grape

Hexi Irrigation Areas of Gansu province is a high quality wine grape area in China. In this experiment, the research object is Cabernet Gernischet wine grapes in MoGao ecological garden in Huang yang zhen of Wuwei. And focuse on developing the Water-saving irrigation automation software and hardware control device using the technology of computers, wireless communications, sensors, automatic control technology. Besides, this paper makes a deep study of the water dynamics and temperature effect as irrigation mulching and coated drip irrigation in Hexi Corridor changes under the condition of Water-saving automatic control. The main results are as follows:After careful study and analysis, this paper developed a joint based on local and remote control, automatic irrigation data acquisition hardware and software irrigation control system, which can detect the different crop soil moisture temperature changes automatically by GCM2010S solar data acquisition system and send the data to your mobile phone or a remote PC control database through the GSM network or over the remote, achieving the automation of agricultural irrigation, intelligent, precision control, water control for the realization of modern agriculture provides a solution.Base on status of large area cultivation of brewing grape and water shortage in Hexi irrigation areas of Gansu Province; using GCM2010S solar data acquisition system while the effects of different water saving measures on soil water content and temperature in droughty desert region were studied in this paper. Main findings are as follows: Firstly, straw mulching significantly reduced the soil moisture evaporation and enhanced the ability of soil water storage and preservation; Secondly, the increases of soil temperature were weakened, so the affects of Straw Mulching to 0~20cm soil temperature obviously reduced when it cools severely, however the inferences decreases with the increased of soil depth; Thirdly, sand-mixed layer soil is unfavorable to water infiltration and favorable to water storage and preservation.
