设计了水肥一体喷杆喷灌机整体结构，根据灌水定额和多孔管路沿程压力分布理

The overall structure of the water and fertilizer integrated spray rod sprinkler irrigation machine was designed. Based on the irrigation theory and the theory of pressure distribution along the porous pipe, the main components such as pipes, pumps, and spray rod mixed fertilizer system were designed and selected; and in 2019 In December, the consistency of the spray volume of the nozzle, the consistency of the fertilizer liquid concentration of the nozzle, and the uniformity of irrigation were tested in the Pengyu Family Farm Test Field (N35 ° 0′44.17 ″, E117 ° 01′21.30 ″) of Longzhuang Village, Suozhen Town, Tengzhou City. The pressure of the water pump is three levels: 0.3MPa, 0.4MPa and 0.5MPa. The position of the rain gauge is divided into four levels: 0m, 50m, 100m, and 150m. The spray volume of each nozzle and the index of fertilizer concentration are tested and analyzed.

The overall structure of the water fertilizer one-body spray spray machine is designed, and according to the theory of pressure distribution of water filling quota and porous pipe along the way, the design and selection of major components such as pipeline, water pump and spray rod mixing and fertilizer system are carried out, and in December 2019, it was designed and selected in Tenzhou City-level Sozhen. Longzhuang Village Pengyu family farm test field (N35?0'44.17", E117?01'21.30") to carry out the spray head injection consistency, nozzle fertilizer concentration constant, irrigation uniformity test. The pump pressure takes 0.3MPa, 0.4MPa, 0.5MPa three levels, the position of the rain barrel is divided into 0m, 50m, 100m, 150m four levels, the test determines and analyzes the spray head spray, fertilizer concentration index.

According to the theory of irrigation quota and pressure distribution along the porous pipeline, the design and selection of main parts and components such as pipeline, water pump and spray bar mixed fertilizer system were carried out. In December 2019, the consistency of spray rate was carried out in Pengyu family farm test field (N35 ° 0 ′ 44.17 ″, E117 ° 01 ′ 21.30 ″) in Longzhuang village, Suo Town, Tengzhou City , the experiment of the consistency of fertilizer concentration and the uniformity of irrigation. The pressure of the water pump is 0.3MPa, 0.4MPa and 0.5MPa, and the position of the rain gauge is divided into four levels, i.e. 0m, 50m, 100m and 150m. The spray amount and fertilizer concentration index of each nozzle are tested and analyzed.
