土壤墒情监测系统在有机葡萄灌溉中的应用

Application of Soil Moisture Monitoring System in the Irrigation of Organic Grape

为了在有机葡萄栽培中实施精量灌溉,提高果实品质,尝试利用土壤墒情监测系统技术。土壤墒情监测系统综合集成了先进的监测设备、网络技术和专家知识经验,能够完成对土壤墒情的实时监测与灌溉决策。将这项技术在上海市奉贤区的1个有机葡萄种植园进行示范,取得了良好的效果,平均每亩增收26%,葡萄可溶性固形物提高了2～3Brix,水分利用效率提高40%,同时劳动生产率提高40%,经济效益显著。本文介绍了该系统的结构、工作原理、布设和调试方法等内容,并结合葡萄各生长期的需水量,对1个大棚1年内的土壤墒情监测数据进行了简要分析。

To carry out accurate irrigation during the cultivation of the organic grapes and develope the fruit quality,we tried to use the soil moisture monitoring system.We integrate advanced monitoring equipment,network technology and expert knowledge and experience into the soil moisture monitoring system,and enable it to monitor the soil moisture content in real-time and make irrigation decisions.Demonstration in a organic grape planation in Fenxian district of Shanghai showed that,the average yield per mu increased by 26%,the soluble solids of the fruit increased by 2~3 Brix,the water use efficiency increased by 40% and the labor efficiency increased by 40%,bringing significant economic benefits as a result.In this article,we described the structure,working principle,layout and adjustment method of the system.And we gave a brief analysis to the soil moisture data of a vinyl house in one year,considering the water demand in each grape growth period.
