Abstract:
Super high-yield is an attractive research field recently as the soybean demand increases.However，the practice of super high-yield is difficult to be repeated as the lack of knowledge of cultivar and the management of super high-yield performance.To understand the specific performance of super high-yield cultivar，we compared the super high-yield cultivar Liaodou 14 and ordinary cultivar Liaodou 11 under different fertilizer levels（150，300 kg hm-2(NH4)2HPO4）and planting densities（7.5，15.0，22.5×104 plants hm-2），the results showed that the plant height of super high-yield cultivar Liaodou 14 was stable under different treatments，and the plants had a lower height of lowest pod，and more branches under the higher fertilizer level.The LAI reached the maximum at podding stage，then decreased stably，and maintained a relative high LAI in the late stage of growth.Significant yield differences were observed among different plant densities，but no significant difference existed under different fertilizer levels.Super high-yield soybean Liaodou 14 can perform better only under the optimal management.
