摘要:通过栽植密度和施肥量二因素四水平三重复随机区组试验结果:对茎叶生物量积累最具优势的组合为密度105万株/hm^2和施肥量240 kg/hm^2,增量为652 mg/d;对单根生物量积累最优组合为密度60万株/hm^2和施肥量240 kg/hm^2,单根重达14.88 g。本试验结果可为党参种植及田间管理提供参考。
Study on the biomass dynamic changes of Codnopsis pilosula(Franch. ) Naff. under the different planting density and fertilizing amount of the four levels respectively via the random methods have showed out : the best combination for the stems and leaves are 1.05 million plant/hm^2 and 240 kg fertilizer/hm^2. Its biomass accumulation can achieve 652mg/d; That for the root are 0. 6 million plant/hm^2 and 240 kg fertilizer/hm^2 and the weight of every fresh root achieved 14.88g. The results will be helpful to cultivating and fertilizing of Codnopsis pilosula.
