Abstract

The invention provides a preparation method of a compound fertilizer for improving soil for planting sweet potato. An organic selenium element compound is prepared by dissolving tartaric acid and diethylene glycolamine with water and ethanol and then using the obtained mixture with selenic acid; then oxalic acid and hydrogen peroxide are subjected to a reaction and are subjected to a mixed reaction with ferrous chloride, manganese chloride, zinc chloride and ammonium chromate to produce an organic compound containing iron, manganese, zinc and chromium elements; and next, turfy soil is mixed with diatomite and plant ash, and then the three mixtures are compounded and mixed with a mixture of diammonium phosphate and potassium dihydrogen phosphate to obtain the product. The prepared compoundfertilizer contains trace elements such as selenium, iron, manganese, zinc and chromium, the content of trace elements of the sweet potato can be improved while the soil fertility can be improved, andthe nutritive value of the sweet potato is improved.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a method for preparing a compound fertilizer for improving the soil for planting sweet potatoes. Background technique [0002] Sweet potato planting has its particularity, especially the planting of pollution-free organic sweet potato, which not only requires that the soil vegetation cover is not stripped, damaged and degraded, but also must be able to provide essential nutrients for its growth, so a fertilizer is needed to maintain good soil properties 1. Improve soil fertility. Trace elements play an equally important physiological role as macroelements in ensuring the normal growth and development of plants. More than half of the farmland soil in my country lacks one or more trace elements. Organic trace elements can overcome the adverse consequences caused by oxidation, antagonism, and precipitation after the application of inorganic trace elements, and have the advantages of stab...
