1僵花球又叫先期现球、早花球。这种花球僵小,有时小到豆粒大小,主要发生在小苗期,茎叶尚未完全长足就长出了小花球。其发生的原因是:秋播过晚、温度降低,通过春化阶段过速,就会先期现球;陈、弱、病害的种子,播种后生长势弱,茎叶不旺盛,及早通过春化阶段,造成植株营养不良,亦会形成早花球;播种早熟种,如播种过迟,叶丛尚未充分成长 A stiff flower ball is also known as the early ball, early flower ball. This flower ball stiff, and sometimes small bean size, mainly in the seedling stage, stems and leaves have not yet fully grown on a small flower ball. The reason for this is as follows: autumn sowing, the temperature decreases, through the vernalization stage over speed, will be the first ball; Chen, weak, disease seeds, seeding growth is weak, stems and leaves are not strong, early through the vernalization Stage, causing plant malnutrition, will also form early flowering ball; sowing precocious species, such as sowing too late, the leaves and plexus have not yet fully grown
