Iron-rich fertilizer special for rice and preparation method thereof

Abstract

The invention discloses an iron-rich fertilizer special for rice. The iron-rich fertilizer is prepared from the raw materials including feces of livestock and poultry, an organic raw material, pig blood, a urea iron complex compound, diaminoferric xanthohumate, ferrous sulfate, iron amino acid chelate, zinc-amino acid chelate, molybdenum amino acid chelate, copper amino acid chelate, sodium tartrate, a sucrose manganese complex, ammonium molybdate, potassium chloride, boric acid, cobalt chloride, sodium selenite, a fertilizer binder, composite microbial strains and the like. The iron-rich fertilizer special for rice is prepared by fermenting natural organic matters, has the advantages of low pollution, high waste utilization ratio and the like, is rich in iron element, can be used for culturing iron-rich rice rich in iron element, and avoids various symptoms caused by iron deficiency of rice, and an effect of supplementing iron for a human body is achieved by eating of the iron-rich rice; when the fertilizer disclosed by the invention is used by mixing with nitrogen, phosphorus and potassium fertilizers, a synergistic effect is achieved, various indexes of rice are superior to that of the rice of the same variety using a common chemical fertilizer, and the yield increasing effect is obvious; and the usage amount of the fertilizer can be reduced, and the utilization ratio of the fertilizer can be improved.

Description

Technical field [0001] The invention relates to the field of pesticides and fertilizers, in particular to a special fertilizer for iron-rich rice 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 iron deficiency anemia and poor pregnancy. WHO data shows that nearly 3.7 billion people in the world lack iron, and iron deficiency has become a serious nutritional problem affecting 30% of the world’s population, especially in countries and regions where plant-based food is the main food. Although iron deficiency can be effectively controlled through food additives and ingestion of tablet drugs, it is difficult to implement in developing countries due to the high costs. [0003] Rice is the second largest food crop in th...

Problems solved by technology

However, like other GM crops, the biosafety of GM rice is still worrying, and there are still many obstacles to the commercial application of GM rice.

In addition, the introduction of exogenous genes also has the problem of efficient and stable expression

In addition, for phytase transgenic rice, due to the poor heat resistance of phytase, the protein activity is greatly reduced after rice cooking, so it is difficult to achieve the expected effect in practice.

Now a lot of iron-rich rice on the market is achieved through post-processing of rice, but there are very few research reports to achieve the goal through fertilization.
