Abstract

The invention discloses a method for restraining potatoes from sprouting, and belongs to the technical field of storage and fresh-keeping of agricultural products. The method comprises the following steps of selecting potatoes, performing healing treatment, performing ultraviolet irradiation, loading the treated potatoes into woven bags, stacking the woven bags, compounding a bud inhibitor, performing treatment, covering stacks with a plastic curtain, performing sealing, performing storage, and performing removal from a warehouse for selling, wherein a bud inhibitor is compounded from one or several kinds of citionella oil, coriander seed oil, mint oil, citronellal, linalool. Through the adoption of the method, the sprouting of the potatoes in the storage process can be effectively restrained, and the storage period can reach 12 months or above. The bud inhibitor adopted by the method is made from natural plant components, so that the bud inhibitor is natural and harmless; and an ultraviolet treatment technique adopted by the method is low in cost, green and safe, and simple to operate.

Description

technical field [0001] The invention belongs to the technical field of storage and preservation of agricultural products, and in particular relates to a method for inhibiting potato germination. Background technique [0002] Potatoes are annual herbaceous plants of the genus Solanum in the family Solanaceae, also known as ground eggs, yams, and potatoes. Potatoes are rich in 8 essential amino acids, carotene, thiamine, riboflavin, niacin, and vitamin C. They are rich in nutrients. They are known as "underground apples" and "second bread". It is one of the most important high-yielding crops for both grain and vegetables in the world. In recent years, with the development of food diversification, non-staple food and processed products using potatoes as raw materials have increased rapidly. [0003] The main problem with potatoes during storage is germination. After the potato is harvested, there will be a dormancy period of about 45 days. At this stage, its growth will temp...
