Not bad performance. Liangyu 88 developed well in the early stage of seeds in the Huang-Huai-Hai region, with strong soil forming ability, and the seedling rate of single seed sowing was over 96%. The Huanghuaihai region starts from the Great Wall in the north, reaches the northern foot of Tongbai Mountain and Dabie Mountain in the south, borders Taihang Mountain and Funiu Mountain in the west, and borders Bohai Sea and Yellow Sea in the east. Its main body is the Huang-Huai-Hai Plain (North China Plain) alluvial by the Yellow River, Huaihe River, Haihe River and their tributaries, and the hills in the south-central Shandong Peninsula adjacent to it.
