本文根据当前人参栽培上无机肥施用现状,对人参施用无机肥后的产量、单支重、等级、折干率等主要指标进行了探讨.研究表明,磷钾肥配合施用,人参可增产73.3%,磷、钾、铜、锰,锌肥配合施用增产87.7%;平均单支重分别增加21.49g和25.6g;平均等级达到2级;特等参和1等参率分别增加44%和46%;折干率增加2.61%和2.84%.微量元素以混合施用效果最好,增产24.0%,其次为施猛区增产17.1%. According to the present status of inorganic fertilizer application in ginseng cultivation, this paper discussed the main indexes of yield, single weight, grade and dryness rate of ginseng after applying inorganic fertilizer. The results showed that with the application of P and K fertilizer, the yield of Ginseng increased 73.3%, and the yield of P, K, Cu, Mn and Zn fertilizer increased 87.7%; the average single branch weight increased 21.49g and 25.6g respectively; Reached grade 2; the participation rate of primary participation 1 and so on increased by 44% and 46% respectively; the drying rate increased by 2.61% and 2.84%. The best effect of mixed application of trace elements, an increase of 24.0%, followed by Shi Meng District 17.1% increase.
