Problems solved by technology
[0003] The existing grid-based or non-grid-based Digital Soil Mapping (DSM) has the problem of mixing input information units, making the mapping results unsuitable for direct use to guide the implementation of precision agriculture. Land plots are the basic management of agricultural production activities. Units have realistic geographical significance for agricultural applications, therefore, the present invention proposes a method for digital mapping of soil nutrients in China's floodplain agricultural areas based on plots to solve the deficiencies in the prior art

Embodiment Construction
[0021] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the examples, which are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.
[0022] This embodiment proposes a method for digital mapping of soil nutrients in China's floodplain agricultural areas based on plots, including the following steps:
[0023] Step 1: Use remote sensing monitoring technology to obtain mid-to-high resolution satellite image data within the monitoring time in the research area, as the basis for judging the attributes of plot data, and then fuse the obtained mid-to-high resolution satellite image data, and then from the fusion data The CNN method is used to automatically extract the boundaries of each plot in the research area. The process of the CNN method is as follows: firstly, by superimposing road and river maps in the research area...

The invention discloses a plot-based soil nutrient digital mapping method for agricultural areas in China proluvial plains, and the method comprises the following steps of acquiring data using the remote sensing monitoring technology, automatically extracting the boundaries of the plot, performing spatial decomposition and typical point generation, establishing a relationship between the plot-based soil nutrient content and the landscape, establishing and implementing a prediction model, and evaluating the prediction accuracy of the prediction model. The invention can achieve more fine soil nutrient data acquisition by using remote sensing monitoring technology, GPS and GIS technology, and the plot-based soil nutrient digital mapping can effectively reduce the number of mapping units in complex agricultural areas, thereby improving the prediction algorithm efficiency by about 4 times, and also achieving better results at the level of details. The plot-based soil nutrient digital mapping has good accuracy of prediction and calculation efficiency, and can be used to draw fine-resolution details of surface soil nutrients.
Description
technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for digital mapping of soil nutrients in China's floodplain agricultural areas based on plots. Background technique [0002] Soil nutrients are the most important soil components, which directly affect plant growth and the supply of raw materials for human life. Precision Agriculture (PA) aims to precisely manage the planting environment through changes across time and space, and provide effective guidance for the application of chemicals and fertilizers, helping Implementers reduce production costs and soil pollution, fine-grained mapping of soil nutrients in large areas is crucial in the decision-making process of precision agriculture, digital soil mapping (DSM) is a relatively effective method, when soil cannot be obtained quickly and cheaply The fine-scale soil information required by PA can be obtained when the characteristics are used. [0003] The existing...
