Novel potash magnesium sulphate fertilizer and preparation method thereof

Abstract

The invention relates to a novel potash magnesium sulphate fertilizer and a preparation method thereof applied to the field of agriculture and forestry production. The novel potash magnesium sulphate fertilizer comprises a macro-element, i.e., potassium, medium elements including sulphur and magnesium, trace elements including manganese, zinc and boron and a plant nutrient absorption enhancer. Compared with other potash magnesium fertilizers, the novel potash magnesium sulphate fertilizer has the advantages of high fertilizer efficiency, comprehensive nutrient and simplicity and convenience in application. The product provided by the invention is produced through the following steps of: with potassium sulphate as a main raw material and magnesium sulfates and zeolite powder as auxiliary raw materials, adding the trace elements such as the manganese, the zinc and the boron according to a certain scientific proportion, meanwhile, adding a certain dose of plant nutrient absorption enhancer, and sufficiently and uniformly mixing all the materials, wherein the magnesium sulfates include magnesium sulfate heptahydrate, magnesium sulfate pentahydrate and magnesium sulfate monohydrate. The product is simple in production process, has easily obtained raw materials and is comprehensive in nutrient; and the pH value of the product is between 7 and 9, so that the product is more suitable for acidic soil and also has the functions of improving the soil and protecting the ecological environment.

Description

technical field [0001] The invention relates to a novel potassium-magnesium sulfate fertilizer, in particular to a novel potassium-magnesium sulfate fertilizer which contains various trace elements and has a pH value between 7-9 and can improve soil and protect the ecological environment and a preparation method thereof. Background technique [0002] Potassium can promote photosynthesis in crops, increase photosynthetic efficiency, and promote the delivery of photosynthetic products. Potassium can also promote the absorption and utilization of nitrogen by crops and promote protein synthesis. Therefore, sufficient potassium supply can not only increase the yield, but also increase the protein content in the grain and improve the quality. However, with the continuous improvement of crop yield and nitrogen and phosphorus fertilizer application, the amount of potassium removed from the soil by crops is gradually increasing, and the amount returned to the soil in the form of org...

Problems solved by technology

However, in recent years, with the large-scale application of chemical fertilizers, crop yields have continued to increase, and the amount of magnesium carried by plants from the soil has continued to increase, and because soil magnesium cannot be effectively supplemented, magnesium deficiency in plants has emerged in various places.
