Problems solved by technology

[0005] Traditional agricultural database organization methods and commonly used geographic grids cannot meet the needs of precision agriculture, and multi-source heterogeneous agricultural grid data also put forward higher requirements for the construction of precision agriculture databases. Therefore, the selection of grids that meet the requirements of precision agriculture The original intention of the present invention is to develop a grid-based agricultural data organization method and data conversion method, so as to realize the information management of precision agriculture

Embodiment Construction

[0048] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0049] like figure 1 As shown, a grid-based precision agriculture database design method of the present invention, the implementation steps are as follows:

[0050] Step (A), determine the application area, and obtain the farmland range according to the actual operation area. The farm in the implementation case is located in a province in Northeast my country. This area is dominated by planting and mainly produces wheat and soybeans. The range of farmland in the implementation of the method is represented by the farmland area layer data.

[0051] Step (B), according to the range of farmland obtained in step (A), combined with the standard system of precision agriculture, determine the unit size of the geographic grid and its hierarchical rule system. In this step, when establishing the geographic grid of the actual area, the grids that do not belong...

Abstract

The invention discloses a grid-based precise agricultural database implementation method, which comprises the following steps of: (A) determining an application area, and obtaining a farmland range according to an actual operation area; (B) establishing a geographic grid according to the farmland range obtained in the step (A); Step (C), hierarchical grid coding is carried out on the geographic grid established in the step (B); (D) according to the geographic grid established in the step (B) and the layered grid coding rule designed in the step (C), obtaining geographic grid data in a range; And step (E), agricultural grid data storage: all data in the agricultural grid database are attribute data of grids, and the main data comprise geographic basic data, crop data, soil data, pest and disease damage data and the like. The requirements of precise agriculture on data are effectively met, precise formula fertilization is achieved, and the purpose of increasing both production and incomeis achieved.

Description

technical field [0001] The invention belongs to the technical field of precision agriculture database design, and in particular relates to a grid-based precision agriculture database implementation method. Background technique [0002] Traditional farmland nutrient management strategies use farmland random soil sampling analysis to determine the average value of soil nutrients, and use these determined average nutrient values ​​to guide farmland nutrient management. The average value is used to represent the soil nutrient status of the entire farmland, and a single amount of fertilizer is applied uniformly. Under the premise that the effective nutrients in the soil are low and the price of chemical fertilizers is low, this uniform fertilization method can be accepted, because the input of nutrient cost is not a key factor to consider . However, with the development and influence of various factors in the social environment, the input cost of agricultural production has incr...
