大棚蔬菜育苗喷灌设备-PGJ-1全自动变轨喷灌机操作原理

普通型双臂自走式喷灌机转为温室灌溉设计，喷灌均匀度高，水滴雾化状况可根据使用目的进行调整，除常规灌溉外还可进行施肥和试药等多种作业。PGJ-1全自动变轨喷灌机悬挂在温室上部的双轨道管上，利用微电脑和磁性号进行控制，并加以遥控装置，自动化程度很高，能够根据用户的选择实现：正向运行、反向运行、连续喷灌，及相应的正向喷淋、反向喷淋以及往返喷淋。喷灌机双臂喷灌管上每个喷头内含有三种不同流量和雾化程度的喷嘴，轻轻转动该喷头就可选择合适的喷嘴。

可以选择使用PGJ-1全自动变轨喷灌机转移系统，将喷灌机从一跨转移到另一跨进行灌溉工作，从而用一台喷灌机完成多跨温室的灌溉任务，以节约投入。PGJ-1全自动变轨喷灌机解决了蔬菜生产中存在的节水灌溉技术问题，获得了很大的社会效益和生态效益，对加强产业的转型升级具有重要作用与意义。

水肥一体化技术是将灌溉与施肥技术融为一体的农业新技术，是当前设施蔬菜生产的关键技术，其可以实现jing准灌溉、jing准施肥，具有节水、节肥、节药、节地和省工、改善土壤及微生态环境。应用水肥一体化技术种植蔬菜，具有生长整齐一致、定植后生长恢复快、提前收获、收获期长、丰产、对环境气象变化适应性强等，可促进设施蔬菜产量的提高和品质的改善。经生产实践，该技术可使番茄、甜瓜平均增产28.8%和22.6%，水肥利用效率平均提高44.3%和29.8%。

Operation principle of pgj-1 automatic track changing sprinkler irrigation equipment for greenhouse vegetable seedling

The ordinary double arm self-propelled sprinkler irrigation machine is designed for greenhouse irrigation, with high uniformity of sprinkler irrigation, and the atomization status of water drops can be adjusted according to the purpose of use. In addition to conventional irrigation, it can also carry out various operations such as fertilization and drug test. Pgj-1 automatic track changing sprinkler irrigation machine is suspended on the double track pipe in the upper part of the greenhouse. It is controlled by microcomputer and magnetic number, and is equipped with remote control device. It is highly automatic and can be realized according to the user's choice: forward running, reverse running, continuous sprinkling, and corresponding forward spraying, reverse spraying and back and forth spraying. There are three kinds of nozzles with different flow rate and atomization degree in each nozzle on the double arm sprinkler irrigation pipe of sprinkler irrigation machine. The appropriate nozzle can be selected by turning the nozzle gently.

We can choose to use pgj-1 automatic orbit changing sprinkler transfer system to transfer the sprinkler from one span to another for irrigation, so as to complete the irrigation task of multi span greenhouse with one sprinkler irrigation machine, so as to save investment. Pgj-1 automatic track changing sprinkler irrigation machine solves the technical problems of water-saving irrigation in vegetable production, obtains great social and ecological benefits, and plays an important role and significance in strengthening the transformation and upgrading of the industry.

Water and fertilizer integration technology is a new agricultural technology which integrates irrigation and fertilization technology. It is the key technology of current facility vegetable production. It can realize Jing quasi irrigation and Jing quasi fertilization. It can save water, fertilizer, medicine, land and labor, and improve soil and micro ecological environment. The application of water and fertilizer integration technology to plant vegetables has the advantages of uniform growth, fast recovery after planting, early harvest, long harvest period, high yield and high quality, and strong adaptability to environmental and meteorological changes, which can promote the improvement of vegetable yield and quality. Through production practice, the average yield of tomato and melon increased by 28.8% and 22.6%, and the water and fertilizer utilization efficiency increased by 44.3% and 29.8% respectively.
