Abstract

The invention relates to a method for keeping watermelon stems fresh and green. Fresh-keeping and green-keeping preparation agent is constituted by complex phosphate water solution, 6-benzyladenine (6-BA) and ginger and garlic complex liquid. After a watermelon is picked, the watermelon stem is dipped in the fresh-keeping and green-keeping preparation agent for 10 seconds and then dried, and the watermelon is stored in the environment with the temperature of 14 DEG C to 16 DEG C. The method provided by the invention has the advantages that wounds of watermelon stems can be promoted to heal quickly, so that the wounds can be prevented from being infected by microorganism; and more than 95% of watermelon stems can keep green obviously during the fresh-keeping period of 3 months and do not droop or wilt, so that the appearance condition and the commodity value of watermelons which are stored can be improved remarkably.

Description

[0001] technical field [0002] The invention belongs to the technical field of fresh-keeping of fruits and vegetables, and in particular relates to a fresh-keeping and green-keeping method for watermelon stems. Background technique [0003] Watermelon, also known as water melon, cold melon, summer melon, is the fruit of Cucurbitaceae watermelon. Because it was introduced from the Western Regions in the Han Dynasty, it is called "watermelon". Watermelon is a traditional summer heat-quenching product in my country. Over the years, the planting area of ​​watermelon in China has been stable at about 20 million mu, with an annual output of more than 30 billion kilograms, ranking first among all kinds of fresh fruits. However, due to climatic reasons, it is difficult to cultivate watermelon all year round in most parts of the country, and it is difficult to preserve it for a long time. Consumption cost of watermelon. On the other hand, many areas in the north are also the main ...
