Problems solved by technology

However, with the aggravation of soil salinization, iron and zinc deficiency in crops is becoming more and more common and serious. Although the existing nitro fertilizers provide crops with high concentrations of nitrogen, phosphorus and potassium, they have improved crop yields. , but because the crops lack the trace mineral elements iron and zinc necessary for their growth, the quality and quality of the crops are also reduced, which in turn affects the nutritional health of humans who eat the crops
In the prior art, in order to improve the performance of fertilizers to chelate trace mineral elements, EDTA is used as a chelating agent and fertilizer corrosion inhibitor, but EDTA not only chelates iron and zinc elements, but also chelates with harmful heavy metal elements present in the soil With the formation of stable chelates, when such fertilizers are applied to crops, the harmful heavy metals absorbed by the crops increase significantly. Eating this crop seriously threatens the health of the human body and poses a huge threat to human health

Abstract

The invention discloses nitro-compound fertilizer and a preparation method thereof. The nitro-compound fertilizer is prepared from the following components in percentage by weight: 10 to 60 percent ofammonium nitrate phosphate fertilizer, 10 to 60 percent of potassium fertilizer, 10 to 60 percent of phosphorus fertilizer and 0.1 to 5 percent of a polymer coated iron and zinc absorption accelerator. The invention also discloses the preparation method for the nitro-compound fertilizer. According to the nitro-compound fertilizer, the polymer coated iron and zinc absorption accelerator is added into the nitrogen, phosphorus and potassium-containing nitro-compound fertilizer, so that a polymer releases an iron and zinc absorption accelerator in a sustained manner in the situation that crops are still lack of microelements, such as iron and zinc, besides absorbing the iron and the zinc under the action of the crops, and the absorption of the iron and the zinc by the crops from soil is accelerated; the microelements, such as the iron and the zinc, required by growth are provided for the growth of the crops; meanwhile, the content of the iron and the zinc of the crops is improved; the mass and the quality of the crops are improved; healthy and nutritional high-quality food is provided for people who eat the crops.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a nitro compound fertilizer for improving the quality and quality of crop products and a preparation method thereof. Background technique [0002] Fertilizer is an important material basis for the development of modern agriculture, and nitro compound fertilizer is a new type of high-efficiency and environmentally friendly chemical fertilizer that has developed rapidly in my country. With the modification of ammonium nitrate for agricultural use, the research and development of nitro compound fertilizer production technology has been continuously developed. Nitro compound fertilizer is safe and reliable, easy to use, good in environmental protection, and high in nutrient content. It not only retains the basic characteristics of the original ammonium nitrate, but also contains nutrients needed for crop growth such as nitrogen, phosphorus, and potassium. It has balanced nutrient...
