甜菊也叫甜叶菊,属菊科植物,种子细小,千粒重仅有0.25—0.4克,幼芽顶土力弱,出苗率低,幼苗生长缓慢,对育苗技术要求较高。育苗不当,出苗率只有10—20％,甚至全不出苗,使栽培计划落空。我们的经验是:精细整地和播后浅盏土是育好苗的基础;加强苗床管理,保持床面湿润是育苗成败的关键。 Stevia, also known as stevia, is an Asteraceae, small seeds, grain weight only 0.25-0.4 grams, top soil weak sprouts, low emergence rate, seedling growth is slow, higher requirements for nursery. Improper nursery, emergence rate of only 10-20%, or even no emergence, so that the plan of cultivation fell through. Our experience is: Fine preparation of soil and sowing shallow soil after sowing is the basis of nursery seedlings; strengthen seedbed management, keep the bed moist is the key to the success or failure of nursery.
