Zhejiang Agricultural University, Hangzhou Fruit Company, Jiangxi Yichun Agricultural School, Yichun Agricultural Bureau and other successive research on the decoction of Chinese herbs to prevent citrus rot. The application of Jingwu, dandelion, galangal, pepper, curcuma, garlic, tea withered, soap horn, eucalyptus leaf, Momordica charantia, neem bark, pepper rind, Qumai, maitake, and other herbs, in order to decoction, soaking method to obtain juice, and with a variety of herbal compositions, used to deal with the post-harvest citrus, have achieved a certain degree of preservation effect, in which galangal, garlic, eucalyptus leaf, etc., the effect is more obvious, such as decoction with wormwood gum together with the If the decoction is combined with shellac, the preservation effect is even better. Fruits and vegetables with this kind of herbal decoction antiseptic, low decay rate, weight loss is also less, fruit appearance full, shiny, delicious flavor, sweet and sour suitable.

Therefore, there is a need to further analyze, identify and purify the active ingredients of Chinese herbs, and to take a step deeper to make anti-seedling determination and storage application test, so as to improve the theoretical and practical application. Because of the existing test in the test plant species is not much, there may be a better effect of Chinese herbs have not been found, which is to be further to test, wide open thinking, a large number of screening, in our country's natural substances to dig, to explore, in order to screen out the antimicrobial effect of a stronger, greater role in preservation of freshness, non-toxic, no side-effects of the excellent biological preparations for fruits and vegetables preservative freshness to add new varieties.
