Method for making soil fertilization prescription diagram, soil accurate fertilization prescription diagram and application

Abstract

The invention relates to a method for making a soil fertilization prescription diagram, a soil precise fertilization prescription diagram made according to the method and application in the aspect ofsoil precise fertilization. The method at least comprises the following steps: collecting soil data: collecting a soil sample at a soil sampling point, recording the latitude, longitude and number ofthe soil sampling point, and investigating field planting information; Wherein the soil data are arranged, the content of soil nutrients in the soil sample is analyzed, and the fertilizing amount required for achieving the target yield is predicted according to an agricultural model; And processing the soil data: importing the soil data into a GIS (Geographic Information System) for spatial interpolation processing to obtain a vector soil fertilization prescription diagram. According to the method and the application of the soil fertilization prescription chart, the problems of low fertilizerutilization rate, high production cost, cultivated land damage and the like in existing agricultural production are solved, the production cost is greatly reduced, the production benefit is improved,and the purpose of cultivated land protection is achieved.

Description

technical field [0001] The invention relates to the field of precision agriculture, in particular to a method for making a soil fertilization prescription map, a soil precision fertilization prescription map and its application in soil precision fertilization. Background technique [0002] In the current traditional agricultural production, most of the production adopts unified management and unified fertilization, which not only causes waste of fertilizers and increases in production costs; reduction and insufficient arable land productivity. [0003] In recent years, with the integration of agricultural land, the gradual formation of family farms and agricultural scale management entities, precision agriculture has developed rapidly. The concept of precision agriculture can greatly reduce production costs, improve production efficiency, and achieve the purpose of farmland protection. However, the existing technology is still limited by many factors such as planting metho...
