Embodiment Construction

[0021] figure 1 A schematic structural diagram showing a corn yield performance evaluation system according to an embodiment of the present invention. Such as figure 1 As shown, the corn yield performance evaluation system includes:

[0022] Data import and preprocessing module: This module mainly completes the import and preprocessing of relevant basic data. The data to be imported mainly include regional test data of corn varieties, statistical data of corn planting area and total corn production in each county (district). The preprocessing to be completed is mainly the verification of data and the regression analysis of the average yield characteristics of each variety, and the calculation of the average corn yield of each county;

[0023] Area selection module: In this embodiment, the calculation of the county-level yield performance of new corn varieties is carried out with the county (district) as the basic unit, and the interested counties should be selected first. ...

Abstract

The invention discloses a novel technical method of evaluating new variety production performance of corn. The production of the corn variety and the average production of planting environment have a remarkable linear correlative relationship; therefore, based on the statistical analysis of corn variety regional testing data, the invention extracts all various production characteristic parameters and establishes an interaction comprehensive model of variety-experiment environment, and then popularizes and obtains an interaction model of variety-large field environment according to the difference coefficient between the experiment region and the large field planting and management level, so as to give a quantitative evaluation for the production performance of the target planting environment such as the corn variety, an evaluation unit is accurate to the county level and concrete variety; therefore, the invention can provide a new method of approving evaluation and accurate marketing for the corn variety, reduces indeterminacy and loss in the corn popularization process and really realizes local conditions.

Description

technical field [0001] The invention belongs to the technical field of planting industry informatization, and in particular, the invention relates to a crop yield performance evaluation system and method. Background technique [0002] When a new crop variety is bred, such as corn, wheat, rice, etc., it is necessary to make a reasonable evaluation of the yield of the crop variety, so that it is of great significance for the promotion and planting of the crop variety. Traditional crop yield performance evaluation methods are limited to crop-level yield performance evaluation, without taking into account the differences among different varieties of the same crop. Many traditional production estimation methods can be summarized into empirical production estimation method, element determination method, satellite remote sensing prediction method, regression model prediction method and so on. In addition, the traditional methods for evaluating the yield of new varieties are mostly...
