Research On The Precision Irrigation System Of Membrane Bag Irrigation Based On Internet Of Things Technology

China has a large population while with little water resource,the water supply and demand are tight,water resources is an important bottleneck of restricting the sustainable development of the future in China.China is an agricultural country,the traditional agricultural water consumption has been huge and irrigation water use efficiency is not high,water resources are badly wasted,intensifying the contradiction between water supply and demand in our country.Therefore,actively promoting new technology of high efficiency water saving irrigation,the internet of things technology is applied to the water saving irrigation,so as to realizing the irrigation system automation and information to demand precising control irrigation of crops,improving the efficiency of water use efficiency and crop production.It is also a development trend of the future water saving agriculture in China and an effective method to solve the shortage of water resources.Membrane bag irrigation technology is a new type of ground water,the irrigation technology has the characteristics of water saving,energy saving,saving both time and labour.It has a high research value and broad application prospects.The field application of membrane bag irrigation technology is still in the exploratory stage.To explore membrane bag irrigation technology field practical application and value of popularization,adopting the combination of theoretical analysis and experimental research methods,studied the membrane bag irrigation soil moist and membrane bag irrigation field experimental research respectively,explore the membrane bag irrigation soil moisture uniformity,daejeon membrane bag soil moisture change rule and the membrane bag water production efficiency,the internet of things technology is applied to membrane bags of precision irrigation decision,solving membrane bags field of timeliness and dynamic as well as the reference data of blindness caused by irrigation decision problem.The results show that:(1)The film hole diameter is 0.5 mm,film hole spacing 30 cm and 50 cm,membrane bag irrigation of 60 and 100 litres of water,the membrane bag irrigation soil moisture uniformity is higher at more than 70%,belonging to high uniformity ground water-saving irrigation technology.At the same time considering the problem of irrigation water and film hole spacing,balancing membrane bags irrigation timeliness and irrigation effect,can further improve the quality of film bag irrigation and irrigation water use efficiency.(2)Membrane bag irrigation daejeon after each observation point,each layer of soil moisture content change trend showing roughly the same rule,namely the earth point of soilmoisture content at the end of the film bag to infuse water gradually decreases with time.About water membrane bags with horizontal distance is different,each observation point each layer and the changes of soil moisture content has certain differences,mainly because the membrane bag irrigation and technical characteristic of the structure and the way of water supply.The same water treatment of membrane bag irrigation and corn factor is better than that of furrow irrigation in open field control group,the yield of per mu yield is about 7.60%on average,membrane bag irrigation technology has certain water production efficiency.(3)Membrane bag precision irrigation in open field in the main irrigation decision is based on the soil moisture data and meteorological data information,monitoring equipment of internet things to ensure the reliable data source and data quality.(4)Building the membrane bag precision irrigation system based on internet of things technology,membrane bag precision irrigation decision model is established,it can realize membrane bag of irrigation time,total system irrrigation water,a single membrane bags accurate forecast irrigation water.With the rapid development of information technology,especially the internet of things technology in the application and popularization of agricultural production,agricultural production gradually incline to accurate,efficient and green development.Membrane bag precision irrigation system based on internet of things technology research trend information for water saving irrigation technology,intelligence,automation,control and accurate to provide scientific reference.
