摘 要：
[Purpose]Family farm,a new type of agricultural production,is being developed vigorously in China.In this way,precision fertilization becomes an important research direction and technical difficulty to meet the needs of modern production management of family farm.With the development of smart phones and mobile Geographical Science Information(GIS)technology,it is more convenient to make real-time and accurate management of farm nutrients.[Method]Therefore,the mobile terminal APP combined with the website management system are the main technical means to achieve accurate fertilization on family farms.In this system,the Kriging interpolation is carried out on the soil nutrient data of the sample points,and then the soil data of the whole plot is analyzed by the nutrient balance fertilization model.Afterwards,the precise fertilization vector can be obtained and will be exported to the mobile terminal.Finally,the system can synchronize the fertilization decision to the Web and this would guide the variable fertilizer applicator to carry out the scheme.[Result](1)The whole system records data through the mobile terminal and manages the land parcel.And then the system uses the data management layer to synchronize the data and upload it to the server in order to generate the recommended fertilization scheme which will be exported to the phone APP and the variable fertilizer applicator;(2)The system carried out preliminary experiments in three experimental bases in Henan Province,Hebei Province and Beijing,and verified the practicality of the system from information collection,entry to nutrient management,and generation of fertilization programs;(3)Relative to traditional fertilization utilization,the precise fertilization scheme of the system can save an average of about 1.2 kg/mu of pure nitrogen.[Conclusion]Compared with the traditional management system,this system is more flexible,more convenient,more efficiency and requires lower skills for users.In this way,the widespread of this system can reduce chemical fertilizer dosage,save costs and reduce environmental pressure,which is of great significance to promote the informatization and modernization of agricultural.
