Problems solved by technology

However, many people cannot adapt to the special fishy smell of kelp, so kelp also has certain limitations as an iodine-rich material, so it is necessary to develop iodine-rich materials suitable for different groups of people
[0011] The patent of CN99120407.7 has reported a kind of iodine-containing fertilizer for fruit and vegetable crops and its manufacture method. However, the process of making iodine fertilizer by this method is complicated, and the energy consumption is extremely high in the preparation process of the fertilizer, which makes the use cost of this fertilizer extremely high, and the iodine content in the fruit and vegetable crops obtained by using this fertilizer is all lower than 20mg/kg, the conversion output and input ratio of its iodine are to

Abstract

The invention discloses an iodine-rich spinach special-purposed fertilizer. The iodine-rich spinach special-purposed fertilizer is prepared from well mixed materials of an iodine source and fertile substances satisfying spinach growth nutrient demand characteristics. The fertilizer comprises the components of, by weight: 1-5 parts of the iodine source (calculated according to the weight of iodine), 3000-5000 parts of an organic fertilizer; 20-30 parts of an NPK fertilizer, 0.34-0.45 parts of an zinc-containing compound (calculated according to the weight of zinc), 0.094-0.2 parts of an iron-containing compound (calculated according to the weight of iron), and 0.1-0.168 parts of a boron-containing compound (calculated according to the weight of boron). The invention also discloses a method for cultivating spinach with the iodine-rich spinach special-purposed fertilizer. The method comprises the steps of: fertilizer preparation, soil preparation and fertilizer application, seed preparation, sowing, managing, and harvesting. The preparation method of the fertilizer provided by the invention is simple. With the fertilizer, iodine-rich spinach can be cultivated. The spinach provided by the invention has high biological iodine content, and extremely high safety.

Description

technical field [0001] The invention relates to a special iodine-rich spinach fertilizer and a method for cultivating spinach, belonging to the technical field of fertilizers. Background technique [0002] Iodine is an essential trace element for the human body, known as the "intellectual element". It participates in the synthesis of thyroid hormones and plays a very important role in human nutrition. WHO recommends that adults should consume 150 μg / d of iodine, and pregnant women should take a slightly higher iodine intake of 200 μg / d, and children should reduce their iodine intake accordingly. [0003] Iodine deficiency in the human body can cause a series of diseases, such as goiter, premature birth, stillbirth, congenital deformities, deafness, dumbness, dementia, etc. can all be caused by iodine deficiency. Iodine deficiency disorders are endemic diseases with the widest distribution and the largest number of cases in the world, and my country is one of the areas with...
