Watermelon rich in iodine and production method thereof

Abstract

The invention discloses a watermelon rich in iodine and a production method thereof. The method comprises the following steps: under routine management and cultivation conditions, a biological agent containing iodine is applied to the surfaces of the leaves of the watermelon since the fifth or sixth day after the watermelon is pollinated, and 600 ml of biological agent is used every time and is diluted with water, which is 120 to 180 times of the biological agent, before being sprayed; the biological agent is sprayed and applied to the surfaces of the leaves of the watermelon; and the biological agent is sprayed once every other 6 to 8 days, the number of spraying times of the biological agent is 3 to 4 in total, and finally the watermelon fruit rich in iodine is obtained. The production method of the watermelon provided by the invention not only solves the domestic ubiquitous problem of iodine deficiency, but also solves the problems that the iodine content of iodized salt is greatly reduced because the iodine content of the iodized salt is likely to be affected by external factors; and the iodized salt is not easy to preserve. The iodine content of the watermelon rich in iodine, produced through the production method, is improved to a great extent and increased by more than 200 times as compared with that of a watermelon produced through a traditional method; and the production method of the watermelon rich in iodine is applicable to the regions of iodine deficiency in our country and has a positive significance for improving the iodine levels of crowds and preventing and treating diseases.
