The invention discloses a natural fruit and vegetable sterilizing fresh-keeping agent, preparation and a use method thereof, which belongs to the technical filed of sterilizing fresh-keeping agent. Every 1L sterilizing fresh-keeping agent comprises the following compositions by weight: 0.1 to 20 grams of grape seed extract, 1 to 50 milliliters of absolute ethyl alcohol, 0 to 0.5 milliliter of Tween-80, and the balance being sterilized water. The method for preparing the sterilizing fresh-keeping agent comprises the following steps: under the conditions of normal temperature and normal pressure, the grape seed extract, the absolute ethyl alcohol are added into the sterilized water, the Tween-80 is added to the mixed solution, and the sterilized water is added into the mixed solution for constant volume; and a glass rod is used for stirring the mixed solution uniformly to obtain the natural fruit and vegetable sterilizing fresh-keeping agent. The use method comprises the following steps: fruits and vegetables are soaked in the natural fruit and vegetable sterilizing fresh-keeping agent, or are soaked at negative pressure, and then the fruits and vegetables are taken out and are dried for further storage. The natural fruit and vegetable sterilizing fresh-keeping agent well solves the problems of rot and reduced quality after picking for the fruits and the vegetables, has low cost, and can effectively reduce use and residual quantity of chemical agents without causing environmental pollution, thereby having great value for development and application.

The invention discloses a method for preparing medicinal material gastrodia elata. The method includes the following steps that 1, tubers of gastrodia elata are taken and washed to remove soil; 2, the tubers, processed in the step 1, of the gastrodia elata are soaked in a NaCl water solution; 3, the tubers, processed in the step 2, of gastrodia elata are cleaned and naturally dried to obtain the medicinal material gastrodia elata. According to the medicinal material gastrodia elata prepared through the method, the medicine yield is 30-38%, measurements of the shape, properties, thin-layer chromatography identification, water content, alcohol extract and gastrodin content all meet quality standards of the astrodia elata item in Pharmacopoeia of the People's Republic of China, generally, the medicinal material gastrodia elata does not fade or is damaged by worms after being placed for one year, and the nitrite content meets related standards. The provided method solves the problem that the tubers of the gastrodia elata rot or mildew in large quantities in a natural drying method, can replace a sulfur fumigation method and a drying method and has high application value.

The invention provides a storage method for improving the germination rate of seed potatoes, which belongs to the technical field of crop seed storage, and comprises the following steps: S1: performing callus treatment on freshly harvested potato seed potatoes for 5-8 days; S2: treating the seed potatoes in step S1 Soak for 5-20min with the pretreatment agent containing the plant extract of the genus Typhoid, and dry in the dark; S3: put the seed potato in step S2 in a mesh bag or a packing box, and store it in a cold storage. The content of isochlorogenic acid in the used Dinggong genus plant extract of the storage method of the present invention is high, and the productive rate of the prepared N-cocoyl compound amino acid is high; the method can reduce soluble starch synthase, polyphenol oxidase and peroxide Enzyme activity, inhibits the growth and reproduction of microorganisms in seed potatoes, prolongs the dormancy period of tubers, and in the process of releasing dormancy of seed potatoes, the activities of soluble starch synthase, polyphenol oxidase and peroxidase increase, increasing the germination rate.
