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. People

Embodiment 1

[0026] 1) Select a good variety, rub the skin of the spinach seeds, soak them in cold water for 22 hours, and change the water once in the middle. After soaking the seeds, remove the seeds and place them in a low-temperature cold storage at 4°C to accelerate germination for 2 days, and then sow the seeds after they germinate;

[0027] 2) Select land with fertile soil and good thermal insulation and water retention, intensive plowing and fine raking, leveling and making furrows, watering before sowing, and after the water seeps down, spread the germinated seeds on the furrow surface, evenly covering 1.5 cm For fine soil, cover the border surface with crop stalks after sowing, cool down and moisturize, prevent heavy rain, and ensure that the seedlings are uniform. After emergence, thin the seedlings where the seedlings are too dense. Ground temperature, watering time in the morning or evening;

[0028] 3) Before the spinach seeds are sown, apply enough base fertilizer, and appl...

Embodiment 2

[0030] 1) Choose a good variety, rub the skin of the spinach seeds, soak them in cold water for 24 hours, and change the water once in the middle. After soaking the seeds, remove the seeds and place them in a low-temperature cold storage at 5°C for 3 days to accelerate germination, and then sow after the seeds germinate;

[0031] 2) Select a plot with fertile soil and good thermal insulation and water retention, intensive plowing and fine harrowing, leveling the border, watering before sowing, and after the water seeps down, spread the germinated seeds on the border surface, evenly covering 2 cm For fine soil, cover the border surface with crop stalks after sowing, cool down and moisturize, prevent heavy rain, and ensure that the seedlings are uniform. After emergence, thin the seedlings where the seedlings are too dense. Ground temperature, watering time in the morning or evening;

[0034] 1) Choose a good variety, rub the skin of the spinach seeds, soak them in cold water for 24 hours, and change the water once in the middle. After soaking the seeds, remove the seeds and place them in a low-temperature cold storage at 4°C for 3 days to accelerate germination, and then sow the seeds after they germinate;

[0035] 2) Select a plot with fertile soil and good thermal insulation and water retention, intensive plowing and fine raking, leveling the border, watering before sowing, and after the water seeps down, sow the germinated seeds in a row on the border surface, covering 2 cm evenly Fine soil, with a row spacing of 12 cm. After sowing, cover the border with crop straw to cool down and moisturize, prevent heavy rain, and ensure that the seedlings are uniform. After emergence, thin the seedlings where the seedlings are too dense. Keep the soil moist to reduce the ground temperature, and water in the morning or evening;

Abstract

The invention discloses a planting method of a spinage rich in iodine, comprising the following steps: 1) a good-qualified variety is selected and the spinage seed is peeled and placed in cold water which is replaced for one time, exposed in low temperature of four to five Celsius system for sprout acceleration after being immersed and is planted after the seeds sprout; 2) fertile soil block of good temperature and water conservation is selected, carefully plowed and harrowed. Seeds with sprouts are widely distributed or planted in rows on the bed surface, seedlings are thinned after coming out at the place where seedling are too close to each other to keep the sol wet; 3) basic fertilizer is applied before spinage is planted, solid iodine organic fertilizer is applied on the soil surface at one time or liquid iodine fertilizer is periodically sprayed before spinage is picked. Owning to the adoption of the invention, not only spinage containing iodine can be nursed, but also the iodine fertilizer left in the soil and the spinage root rich in iodine can increase the iodine background content in the soil and the surroundings so as to gradually improve the environment in the area short of iodine and enhance the iodine content in food chain.

Description

technical field [0001] The invention relates to a cultivation method of iodine-enriched spinach. Background technique [0002] Iodine is an essential trace element for the human body. It plays an extremely important role in the metabolic process of the human body. More than one-third of the iodine in the human body exists in the form of the thyroid gland. Without iodine, the thyroid gland cannot synthesize thyroxine. It has biological functions such as promoting protein synthesis, regulating energy conversion, accelerating growth and development, and maintaining the structure of the central nervous system. Therefore, iodine deficiency in the human body will lead to a series of physiological disorders and abnormal biological functions, especially when babies are iodine deficient during growth and development. It can cause intellectual disability, and the overall impact on the human body due to iodine deficiency is called "iodine deficiency disease" (IDD). [0003] According ...
