Analysis of the result of the regional experimental Shaxian point of the late ripening group of early rice in the middle and lower reaches of the Yangtze River in 2022

A comparative analysis of the main economic characteristics of the regional tests of 8 early varieties shows that the early output of Qiliangyou is 7102.5 kg·hm⁻²,ranking first, with a yield increase of 2.04% compared with the control, and the increase in yield is not significant, and the yield of Suiyou636 is 7042.5 kg·hm⁻², compared with control, the production increase was1.18%, and the production increase was not significant. The output of the middle and 97 was 6192.5 kg·hm⁻², compared with control output of 11.03%, and the production reduction was extremely significant. The output of Lingliangyou078 was 6385.05 kg·hm⁻², compared with the control, the yield was 8.26%, and the production reduction was extremely significant. The rest of the varieties reduced production to varying degrees compared with the control varieties. The analysis of the results shows that Qiliangyou early output is relatively prominent, and the fertility period Moderate, comprehensive characteristics are balanced, and have a certain potential for promotion. It is recommended to enter the next stage of testing.
