[0099] Example 1
[0100] The method of using 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, the method for measuring the initial vertical angle of planting rice provided by the embodiment of the present invention includes: fixing the horizontal movement ruler of the angle measuring instrument to an appropriate height H of the vertical ruler according to the height of the rice, and recording the horizontal movement of the rice. The width F of the ruler can be calculated using the arctangent function formula DEGREES(ATAN(F / H)) to obtain the vertical angle of rice.

[0109] Example 3
[0110] The method of using 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 As shown, the calculation of the vertical rice skewness provided by the embodiment of the present invention is specifically:
[0111] S201: Delimit the four directions of east, west, south and north, and use the ground plane as the horizontal line to measure the rice skew angles in the four directions respectively;
[0112] S202: Obtain the initial vertical angle of planting rice, and count it as angle A, 0°≤A≤90°;
[0113] S203: Measure the skew angle of the rice planting after experiencing harsh environments with an angle measuring instrument, and count it as angle B, 0°≤B≤90°;
[0114] S204, use the formula "C=A-B" to calculate the skew angle of the upright rice, where C is the skew angle of the upright rice;
[0115] S205: Calculate the skewness of the upright ri...
