Iodine-contained sweet potato planting method

Abstract

The iodine containing sweet potato planting process includes the following steps: 1. raising sweet potato seedling with high quality seed sweet potato; and 2. preparing land, forming furrow, applying solid organic iodine fertilizer in 15mg / m2-150 mg / sq m and abundant base fertilizer, stem planting, covering the land with rice straw, and applying organic fertilizer and composite fertilizer during the growth period of sweet potato. The iodine containing sweet potato provides people with iodine. What is more important is that the residual iodine can increase iodine content in the soil, improve the ecological environment in iodine deficiency area, and prevent and treat iodine deficiency diseases effectively.

Description

technical field [0001] The invention relates to a method for planting iodine-containing sweet potatoes. Background technique [0002] Iodine is an essential trace element for the human body. More than one-third of the iodine in the human body exists in the form of thyroid gland. There must be 3 or 4 iodine atoms in each molecule of thyroid gland. Without iodine, the thyroid gland cannot synthesize thyroxine, which can promote protein synthesis. , activate more than 100 enzymes, regulate energy conversion, accelerate growth and development, maintain the structure of the central nervous system and other biological functions, so iodine deficiency in the human body will lead to a series of physiological disorders and abnormal biological functions, especially iodine deficiency in infants during growth and development , can cause intellectual disability, and this kind is called as " iodine deficiency disease " (IDD) because of the overall influence that iodine deficiency causes t...

Problems solved by technology

However, it has also been exposed in practice for many years that there are some obvious defects in this measure: the one is that the inorganic iodine added in table salt is volatile, and part of the iodine will be lost during storage, transportation and cooking, so the concentration of iodine added in table salt is very low. In addition, there are obvious individual differences in the absorption of inorganic iodine in salt by the human body, so that it is difficult to quantitatively evaluate its biological effectiveness; second, the iodine in the organism has the characteristics of double thresholds, that is, high iodine or low iodine Iodine will have different properties and different degrees of biological effects on the body. High iodine intake can also cause disease. Studies have shown that thyroid cancer is also related to excessive intake of iodine. People of different ages and categories, such as children, adults, The daily iodine requirements of pregnant women and lactating mothers are very different (Table 1). When iodine supplementation is implemented for the people who are really iodine deficient, it is also necessary to give iodine supplements to those who are not deficient in iodine, and even a small number of people who have excessive iodine intake People forcibly supplement iodine. According to the relevant data, the high iodine disease caused by excessive iodine intake has been published in China in recent years. 1 United Nations Children's Fund (UNICEF), World Health Organization (WHO) and international
