[0106] (2.4) determ...

Embodiment 3

[0110] The method for utilizing the lodging resistance index to assist rice breeding provided by the embodiments of the present invention is as follows: figure 1 As shown, as a preferred embodiment, such as image 3 Shown, the calculation of the upright rice skewness that the embodiment of the present invention provides is specifically:

[0111] S201, delineate four directions of east, west, south and north, and use the ground plane as a horizontal line to measure the skew angle of rice in the four directions respectively;

[0112] S202, obtain the initial upright angle of planting rice, count it as angle A, 0°≤A≤90°;

[0113] S203, using an angle measuring instrument to measure the skew angle of the rice planted after experiencing the harsh environment, counting it as angle B, 0°≤B≤90°;

[0114] S204, using the formula "C=A-B" to calculate the skew angle of the erect rice, where C is the skew angle of the erect rice;

[0115] S205, calculating the skewness of the erected r...

Abstract

The invention belongs to the technical field of rice cultivation, and discloses a method and a system for assisting rice breeding by utilizing a lodging-resistant index. The system for assisting ricebreeding by utilizing the lodging-resistant index comprises an initial angle calculation module, a rainfall monitoring module, a wind power monitoring module, a central control module, a skew angle calculation module, a single plant lodging index calculation module, an average lodging index calculation module, a lodging-resistant rice screening module, a yield calculation module, a high-yield ricescreening module, a rice hybridization module and a rice selfing module. The formulation of the preliminary identification index of the lodging resistance of rice is based on the lodging process of the rice under simulated natural conditions, and the lodging resistance of a plant population can be quantitatively evaluated; and high-yield factors are taken into consideration during rice variety breeding, lodging resistance and high yield can be combined, and the lodging resistance and yield of the bred new rice strain are higher.

Description

technical field [0001] The invention belongs to the technical field of rice cultivation, and in particular relates to a method and system for assisting rice breeding by using lodging resistance index. Background technique [0002] At present: Lodging refers to the phenomenon that the upright crops are skewed in pieces, and even the whole plant falls to the ground. Lodging can reduce the yield and quality of crops and make harvesting difficult. When the rice is seriously lodging, the yield can even be reduced by more than half. Lodging mostly occurs in the middle and late stages of crop growth. The earlier the rice lodging after jointing, the greater the loss. The measures to prevent lodging in the prior art are mainly to select lodging-resistant rice varieties for cultivation, but the screening of rice lodging-resistant varieties is mainly determined by visual observation or genetic testing; there is no specific quantitative standard for determining lodging-resistant vari...
