1983年秋至1984年春初的冬季,吉林省与黑龙江省普遍发生了严重的人参根部冻害,尤其是秋季新移植的人参受害更重。受害面积高达数十万平方米,损失严重。冻害的主要表现是烂芽胞,烂芦,有的主根颇似烫熟样。为了防止人参生产遭受冻害损失,我们对1983年冬季期间人参休眠期的冻害,进行了冻因分析,并提出以下预防措施,供参考。 In the winter of 1983 to the beginning of 1984, severe ginseng roots frost damage occurred in Jilin Province and Heilongjiang Province, especially in the autumn. Damaged area of ​​up to hundreds of thousands of square meters, the loss is serious. Frost damage is the main manifestation of rotten spores, rotten roots, and some of the main root quite like cooked. In order to prevent the loss of frost damage caused by ginseng production, we conducted a freeze-thaw analysis on the frost damage during the ginseng dormancy period in 1983 and proposed the following preventive measures for reference.
