Design And Implementation Of Kiwifruit Fertilization System Based On Andriod

“Internet+” modern agriculture is the technical support for sustainable development of agriculture and the strategy of rural vitalization,and it is a new driving force for the development of smart agriculture.These years,there are problems in the fertilization methods of fruit growers in China,such as fertilizing based on experience and habits,inconsistent fertilization standards,coexistence of excessive and insufficiency in fertilizer.This paper takes kiwifruit industry as an example,which is characteristic agriculture of Shaanxi Province's,uses Arc GIS for Android technology,adopts the nutrient balanced method which made this system more accurate in calculation and more valuable,and combines Android smart terminals,then,design a Android-based kiwifruit fertilization system.The system can reflects the development of digitalization and informatization,and is basing on years of soil testing and formulated fertilization.The results provide theoretical basis and technical support for the mapping in nutrients,orchard management,smart fertilization and sustainable development of fruit industry.This research mainly achieved the following results:(1)Developing the application of kiwifruit smart fertilization system.Combining high technology of "Internet +" modern agricultural and advanced theory smart agriculture,at the same time,Arc GIS for Android that belongs to mobile GIS technology is combined with nutrient balanced fertilization model,and aiming at smart fertilization,to achieve kiwifruit fertilization System in Android Studio platform,combining spatial query with attribute query,with a view to provide scientific basis and technical support for the application and popularization of soil testing and formulated fertilization technology;(2)Deep coupling between fertilization model of kiwifruit and mobile GIS.Developing a recommendation system for fertilizing fruit trees center on kiwifruit,which is different from previous fertilization systems that center on crop.It is special that fertilizing in fruit trees,so,it is necessary that Random Forest algorithm is used to predict spatial distribution of soil nutrients in kiwifruit orchards,then,establishing nutrient balanced fertilization model of kiwifruit,combining mobile GIS technology,to achieve precision fertilization;(3)The kiwifruit fertilization system is rich in functions.The appication not only provides recommendation of fertilizer rate in kiwifruit,but also provides mapping location,soil nutrient information in orchard,management knowledge of kiwifruit growth,agricultural technical services such as fertilizer trading,etc,and some extra functions such as kiwifruit fertilization technology videos and so on.The system basically meets the business needs of fertilizing in kiwifruit,and it can be developed into a full-scale smart management expert system in kiwifruit;(4)The application of kiwifruit fertilization system has broad prospects.The system has successfully built an appication architecture,and constructed a nutrient balanced fertilization model of kiwifruit.It has been applied in practical production and has practical significance and practical guidance.In the future,with the expansion of field experiments in kiwifruit,and the advancement of technology of measuring soil,the fertilization model will be more close to the actual production and application of kiwifruit.Therefore,the development space of kiwifruit fertilization application is huge.
