In recent years, Shilin County, Yunnan Province has established several advantages such as good light and heat resources, relatively rich and abundant land, adjustment of planting structure, and early maturity of agricultural products. And other characteristic industries. The plateau ecological agriculture has troubled the local government for a long time in the management of water and fertilizer. In 2017, the local government introduced Topun Cloud Farming rainwater supplement irrigation, water and fertilizer integration technology, of which 1,500 acres of IoT water and fertilizer integration technology demonstration area was built; conventional water and fertilizer integration technology demonstration Area 500 acres; 150 acres of small water cellar demonstration area in the field.
The Shilin County Water and Fertilizer Integration Project in Yunnan Province covers three bases including Lianhong Apple Orchard, Jinlizi Big Cherry Orchard, and Ginseng Fruit. According to the conditions of different bases, water and fertilizer integration technology should be implemented according to local conditions.
The apple orchard and cherry orchard use compensation drip irrigation mode, which is easy to operate, and solves the problem that traditional dripper cannot automatically fertilize, the artificial fertilization caused by automatic irrigation is difficult, the fertilization is uneven, the labor cost is high, the fertilizer waste is serious, and it is not convenient for science and automation. Management issues.
The ginseng orchard adopts the patch drip irrigation mode. The dripper can be accurately installed at the root of the crop, ensuring precise control of water and fertilizer.
The integrated water and fertilizer system has a management cloud platform and a mobile APP. Managers can view the orchard soil data (soil moisture, pH, EC), orchard status, video images, agricultural management, inventory management, and harvest through the mobile APP or the management cloud platform. Management, and one-click control of water and fertilizer programs through the webpage or APP to achieve automatic irrigation.
In March 2018, the leaders of the provincial and municipal soil and fertilizer stations visited Shilin County to investigate the application of water and fertilizer integration. Experts said that the demonstration application of stone forest water and fertilizer integration technology has set a benchmark for the construction of water and fertilizer integration in sloping fields in Yunnan Province and solved the traditional water and fertilizer integration Many of the system's shortcomings are important technical means to achieve ecological green agriculture on the plateau.
