Abstract

The invention discloses an iron-rich and strontium-rich special fertilizer for paddy rice. The iron-rich and strontium-rich special fertilizer for paddy rice is prepared from raw materials such as humic acid, livestock manure, organic substances, porcine blood, iron-containing compounds, L-asparaginic acid chelate strontium, complex trace elements and a fertilizer binder. The invention also provides a preparation method of the fertilizer. The preparation method comprises the steps such as crushing, fermenting, drying and pelletizing. By adding the content of iron and strontium in the fertilizer, the paddy rice is prompted to absorb and accumulate iron and strontium elements, iron-rich and strontium-rich paddy rice is cultured, the iron content and the strontium content in the paddy rice prepared from the produced iron-rich and strontium-rich paddy rice are greatly improved; secondly, the iron-rich and strontium-rich special fertilizer for paddy rice is wide in raw material source, low in price and rich in natural organisms, and can change waste materials into things of value; and the preparation method is simple and practicable, also can reduce the usage amount of the chemical fertilizer and has the advantages of improving economic benefits and protecting the agricultural environment at the same time.

Description

technical field [0001] The invention relates to the field of pesticides and chemical fertilizers, in particular to an iron-rich and strontium-rich rice special fertilizer and a preparation method thereof. Background technique [0002] Iron is an essential trace element for the human body. Its main function is to combine with hemoglobin and myoglobin to form red blood cells, and participate in the transport and exchange of oxygen and carbon dioxide in tissues. Iron deficiency can lead to the occurrence of iron deficiency anemia and adverse pregnancy. According to WHO data, nearly 3.7 billion people in the world are iron deficient, and iron deficiency has become a serious nutritional problem affecting 30% of the world's population, especially those countries and regions where plant foods are the main food. Although iron deficiency can be effectively controlled through food additives and ingested tablet medications, it is difficult to implement in developing countries due to t...
