1982年秋,中国科学院土壤微量元素分析考察团,以林土所方肇伦付所长为团长、南京土壤所唐丽华同志和笔者为团员一行三人,前往友好邻邦朝鲜民主主义人民共和国进行了为时两周的考察。承朝方的周密安排和热情接待,我们对朝鲜科学院地质地理所、植物所、咸兴分院无机化学所、农科院土壤所、沙里院农业大学、朝中友谊合作农场以及其它许多单位进行了参观访问或业务交流。收获是多方面的,在此我仅将所了解到的朝鲜微量元素土壤农化研究方面的情况向读者作一简单介绍。 朝鲜对微量元素土壤农化研究投入了很大力量,至今大致开展了以下三个方面的工作:(1)科学院地质地理所对西部地区土壤微量元素全量与可溶态含量的分析研究;(2)农科院土壤所与各农大土壤室对各地有效态微量元素含量和施肥效果的研究;(3)每4年一次全国性土壤有效态微量元素普查工作。
The autumn of 1982, the Chinese Academy of Sciences soil trace element analysis delegation to forest and land Fangzhao Lun paid director as head, Nanjing Institute of soil by Comrade Tang Lihua and the author as a member of a trip to the friendly neighbor Democratic People’s Republic of Korea for the time being Two weeks of inspection. Thanks to the careful arrangement and warm reception of the DPRK, we visited the Institute of Geology and Geography of North Korean Academy of Sciences, the Institute of Inorganic Chemistry of the Xianxing Branch, the Institute of Inorganic Chemistry of the Academy of Agricultural Sciences, the Institute of Soil Science of the Chinese Academy of Agricultural Sciences, the Agricultural University of Salliya, the DPRK-China Friendship Cooperation Farm and many other units Visit or business exchange. The harvest is multifaceted, and I hereby give a brief introduction to the reader about what we have learned about North Korean trace element soil agronomy research. North Korea has devoted a great deal of effort to the research of trace element soil agriculture. Up to now, the following three aspects have been carried out: (1) Analysis of total and soluble trace elements in soil in western China; (2) ) Institute of Soil Science and Agricultural Sciences of the soil chamber on the effective state of trace elements and fertilization effect of the study; (3) Once every 4 years, the national soil available trace elements survey.
