Abstract

Abstract:

In order to clarify the effects of different seedling cultivation methods on the main agronomic traits and yield of winemaking sorghum, the sorghum variety Yinuohong 8 was selected as the experimental material, and the development process, traits and yield components of sorghum seedlings were compared and analyzed from 2022 to 2023. The results showed that the root number of seedlings in sorghum was higher in traditional sowing method than that of other seedling cultivation methods. Under the floating seedling cultivation method, the hundred-seedling weight and seedling emergence rate of sorghum were higher than those of other treatments. The traditional sowing method extended the sowing-transplanting period and the whole growth period, shortened the period from transplanting to heading stage, and had the lowest yield. The floating seedling cultivation method can achieve high yield by increasing the panicle weight. There was a significantly negative correlation between sorghum yield and the number of days in the sowing-transplanting period, and the correlation coefficient was -0.93. Therefore, combined with the production needs of sorghum in various places and according to local conditions, it is recommended to use floating seedling cultivation method for the best effect.

Key words: winemaking sorghum, seedling cultivation, agronomic characters, yield
