Embodiment Construction

[0056] The overall technical idea of ​​the present invention is to first divide the whole area (such as a county) into units with consistent soil types, clear land use patterns, and clear administrative affiliation. For the target plot designated by the grower, determine the unit it belongs to, and estimate the soil property parameters based on the sampled units adjacent to the unit it belongs to. In addition, according to the estimated results, calculate the soil fertilizer scheme corresponding to the target plot, and inform the grower.

[0057] The technical solutions of the present invention will be described in detail below using specific examples and referring to the accompanying drawings, which are not considered to limit the present invention.

[0058] In order to solve the technical problem of providing the soil fertilizer scheme of the target plot in real time for the growers of each plot, the present invention provides a system 100 for real-time feedback of the soil ...

Abstract

The present invention discloses a soil attribute parameter estimation method, a fertilizer application program recommended method and a fertilizer application program recommended apparatus. The estimation method is as follows: a block formed by superposition of a soil map, a land use actuality map, an administrative map and a sampled point bitmap is used for generating fertilization guide units; sampled fertilization guide units at the periphery of a target fertilization guide unit are identified, sampled fertilization guide units with first key fields same as a first key field of the target fertilization guide unit are selected as an estimation range; when the first key fields of the all the sampled fertilization guide units at the periphery of the target fertilization guide unit are not same as the first key field of the target fertilization guide unit, sampled fertilization guide units with second key fields same as a second key field of the target fertilization guide unit are selected as the estimation range; and soil attribute parameters of the sampled fertilization guide units in the estimation range are used for assignment of soil attribute parameters of the target fertilization guide unit.

Description

technical field [0001] The invention relates to the field of soil fertilization, in particular to a method for estimating soil property parameters and a method for recommending fertilizer matching schemes. Background technique [0002] Soil is the basis for the production of crops. Due to the influence of various factors such as planting methods, fertilizer distribution, and cultivation, there are large differences in soil property parameters in different plots. In the process of refined planting, it is necessary to implement differentiated cultivation and fertilization programs according to the different soil conditions of each plot, so as to adapt to local conditions and increase production. It can be seen that it is particularly important for the growers of each land plot to know the soil attribute parameters of the cultivated land in advance for scientific and efficient agricultural production activities. [0003] However, for the acquisition of soil property parameters...
