摘要
Abstract
Liuyang Black Soybean is a high-quality local germplasm resource and characteristic agricultural product of Liu-yang City,Hunan Province.To refine the high-yield cultivation techniques for Liuyang Black Soybean,a field experiment was conducted in 2023 in Jintian Village,Daxu Town,Liuyang City,Hunan Province.The experiment compared and ana-lyzed the agronomic traits,yield,and yield components of Liuyang Black Soybean under different sowing dates and planting densities.The results showed that both sowing date and planting density significantly affected the yield of Liuyang Black Soybean.As the sowing date was delayed,the yield exhibited a trend of increasing initially and then decreasing.With in-creasing planting density,the yield of spring-sown and summer-sown Liuyang Black Soybean also showed a trend of in-creasing initially and then decreasing,while the yield of autumn-sown soybean gradually increased.Comprehensively,the suitable sowing period for Liuyang Black Soybean is summer sowing,and the suitable planting density is 180 000 plants per hectare.关键词
