目前,日本,朝鲜等国均采用农田栽培人参。通过人工配土施用大量有机肥料,以求改良土壤和取得高产优质的人参。我所二十年来,对农田改上培肥进行栽参,取得了显著效果。资料表明:土壤中的氮素营养是人参合成氨基酸,蛋白质的重要物质来源。力了经济合理补给人参生育期间所需的氮素营养及了解氮素在人参主要器官的分布情况,找出施肥整地后,来自土壤和肥料的氮素营养比率:试验采用了同位素
At present, Japan, North Korea and other countries are using farmland cultivation of ginseng. Apply a large amount of organic fertilizer through artificial soil, in order to improve the soil and obtain high yield and high quality ginseng. In the past 20 years, I have cultivated ginseng by changing farmland into fertilizers and achieved remarkable results. Data show that: soil nitrogen nutrition is ginseng amino acids, proteins, an important source of material. In order to find out the distribution of nitrogen in ginseng’s main organs during economic growth, find out the ratio of nitrogen nutrition from soil and fertilizer after fertilization and soil preparation: the experiment uses isotopes
