施用化肥对人参产量性状的影响

根据当前人参生产中化肥的施用现状，对人参施用化肥后的产量、单支重、等级等主要指标进行了研究。结果表明：磷钾肥配合施用，人参可增产73．3％；磷、钾、铜、锰、锌肥配合施用，可增产87．7％；平均单支重分别增加21．4g和25．6g；平均等级达到2级；特等参和一等参率分别增加44．0％和46．0％；微量元素以混合施用效果最好，增产24．0％；其次为施锰处理，增产17．1％。

Effect of Inorganic Fertilizers on Yield Properties of Ginseng

On the basis of the current application of inorganic fertilizer to ginseng cultivation, we made a study on such indexes as yield, weight of single root, grade and rate of desiccation of ginseng This study showed that when P and K fertilizers were applied together, ginseng yield increased by 73 3%; when P, K, Cu, Mn and Zn were applied together, yield increased by 87 7%; weight of single root increased by 21 4?g and 25 6?g separately; average grade reached grade 2; rates of special grade and grade 1 increased by 44 0% and 46 0% When such elements were applied in a mixed way, the best result was reached, with an increasing yield of 24 0% Under the condition of applying Mn alone, an increasing yield of 17 1% was obtained
