Special fertilizer for iodine-rich and iron-rich paddy rice and preparation method of special fertilizer

Abstract

The invention discloses special fertilizer for iodine-rich and iron-rich paddy rice. The fertilizer is prepared from raw materials such as laver, kelp, mussel, prawn shells, shells, nitratine, air potatoes, Enteromorpha, organic raw materials, fly ash, pig blood, poultry and livestock manure, a urea-iron complex, diaminoferric xanthohumate, ferrous sulfate, compound microelements, animal amino acids, composite microbial strains and the like. The invention further provides a preparation method of the fertilizer. The method comprises steps of crushing, fermentation, drying, granulation and the like. The content of iodine and the content of iron in the fertilizer are increased, absorption and accumulation of iodine and iron elements by the paddy rice are promoted, the iodine-rich and iron-rich paddy rice is cultivated, the content of iodine and the content of iron of rice produced from the produced iodine-rich and iron-rich paddy rice are substantially increased, sources are wide, the price is low, waste can be turned into wealth, the preparation method is simple and easy to implement, the use amount of chemical fertilizer can be reduced, and the fertilizer and the method have the advantages that the economic benefit can be increased and the environment can be protected.

Description

technical field [0001] The invention relates to the field of pesticides and chemical fertilizers, in particular to a special fertilizer rich in iodine and iron for rice and a preparation method thereof. Background technique [0002] Iodine is an essential trace element for the human body. Too much or too little iodine in the human body can cause thyroid disease. At present, iodine deficiency is a serious world health problem in the whole world. At least 118 countries are seriously endangered by iodine deficiency, and nearly 1.6 billion people live in an environment of iodine deficiency. The iodine content in the whole grain is very low, which is extremely unfavorable to the crowd who need iodine supplementation as the main element, so countries all over the world adopt iodized salt method to prevent and control iodine deficiency one after another. [0003] However, there are taboos for eating iodized salt: avoid high temperature, high temperature will affect the stability o...
