大棚蔬菜育苗噴灌設(shè)備-PGJ-1全自動變軌噴灌機操作原理

普通型雙臂自走式噴灌機轉(zhuǎn)為溫室灌溉設(shè)計，噴灌均勻度高，水滴霧化狀況可根據(jù)使用目的進行調(diào)整，除常規(guī)灌溉外還可進行施肥和試藥等多種作業(yè)。PGJ-1全自動變軌噴灌機懸掛在溫室上部的雙軌道管上，利用微電腦和磁性號進行控制，并加以遙控裝置，自動化程度很高，能夠根據(jù)用戶的選擇實現(xiàn)：正向運行、反向運行、連續(xù)噴灌，及相應(yīng)的正向噴淋、反向噴淋以及往返噴淋。噴灌機雙臂噴灌管上每個噴頭內(nèi)含有三種不同流量和霧化程度的噴嘴，輕輕轉(zhuǎn)動該噴頭就可選擇合適的噴嘴。

可以選擇使用PGJ-1全自動變軌噴灌機轉(zhuǎn)移系統(tǒng)，將噴灌機從一跨轉(zhuǎn)移到另一跨進行灌溉工作，從而用一臺噴灌機完成多跨溫室的灌溉任務(wù)，以節(jié)約投入。PGJ-1全自動變軌噴灌機解決了蔬菜生產(chǎn)中存在的節(jié)水灌溉技術(shù)問題，獲得了很大的社會效益和生態(tài)效益，對加強產(chǎn)業(yè)的轉(zhuǎn)型升級具有重要作用與意義。

水肥一體化技術(shù)是將灌溉與施肥技術(shù)融為一體的農(nóng)業(yè)新技術(shù)，是當(dāng)前設(shè)施蔬菜生產(chǎn)的關(guān)鍵技術(shù)，其可以實現(xiàn)jing準(zhǔn)灌溉、jing準(zhǔn)施肥，具有節(jié)水、節(jié)肥、節(jié)藥、節(jié)地和省工、改善土壤及微生態(tài)環(huán)境。應(yīng)用水肥一體化技術(shù)種植蔬菜，具有生長整齊一致、定植后生長恢復(fù)快、提前收獲、收獲期長、豐產(chǎn)、對環(huán)境氣象變化適應(yīng)性強等，可促進設(shè)施蔬菜產(chǎn)量的提高和品質(zhì)的改善。經(jīng)生產(chǎn)實踐，該技術(shù)可使番茄、甜瓜平均增產(chǎn)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.
