Influence of sowing time and density on the yield and yield components of Yangmai 25
In order to explore the suitable sowing period and density conditions for the promotion and planting of Yangmai 25 in the central Anhui region,and to further improve the high-yield cultivation technology of Yangmai 25,this study analyzed the effective panicle number,grain number per panicle,thousand grain weight,and yield of Yangmai 25 under different sowing period and density conditions.The results indicated that both sowing time and density could affects the yield structure of Yangmai 25.With the delay of sowing time,the effective panicle number,grain number per panicle,and thousand grain weight of Yangmai 25 showed a trend of first increasing and then decreasing.The yield was higher in the sowing treatment from November 2nd to 9th.As the density increases,the effective number of ears of Yangmai 25 gradually increases,the number of grains per ear first increases and then decreases,and the thousand grain weight gradually decreases.The yield was higher when the basic seedling density was 2.55-2.70 million/hm2.Under suitable sowing date and density conditions,the yield components of Yangmai 25 were coordinated,which was beneficial for high yield.The experimental results provided sowing date and density affects for high-yield cultivation of Yangmai 25 in the study area and the similar ecological location.
