中药当中有很大的一部分,多数是根、根莖和种子类生药,很容易發生虫害。由于害虫的繁殖力很大,蔓延非常迅速,在短时間內,就能把大批的药材蛀蝕破坏,造成很大的損失。而且由于害虫在生活过程中所排泄出来的水分和散發的热量,使得药材的含水量和温度上升,給微生物也創造了活动的条件,这时药材往往还容易發霉,所以俗諺常說,“虫霉不分”。自然在这种情况下,药材中所含的有效成分也不能不受到影响,而被破坏。因此,如何在貯藏过程中防治蛀虫是个大問題。目前国內貯藏中药,每年因虫害造成的損失是相当大的。当然設备不完善也是一个原因,但在方法上和管理上也存在不少缺点。要是貯存方法得宜,並且经常常加以檢查,發現害虫滋生能及时的扑灭,就能大大减少害虫的發生。 There are a large number of Chinese medicines, most of which are raw medicines such as roots, rhizomes and seeds, which are prone to insect pests. Due to the great reproduction of pests, the spread is very rapid. In a short period of time, a large number of medicinal herbs can be destroyed and destroyed, causing great losses. And because the moisture and heat released by pests during their lives increase the water content and temperature of medicinal materials, they also create conditions for microorganisms. At this time, medicinal materials are often easy to mold. Therefore, they often say, “ Insect mold is not divided.” Naturally, in this case, the active ingredients contained in the medicinal materials cannot be affected and destroyed. Therefore, how to control locusts during storage is a big problem. At present, domestic storage of Chinese medicine, the annual loss due to insect damage is considerable. Of course, imperfect equipment is also a cause, but there are also many shortcomings in terms of methods and management. If the method of storage is appropriate, and it is often checked, it is found that the breeding of pests can be extinguished in time, which can greatly reduce the occurrence of pests.
