Abstract

The invention in particular relates to a middle element fertilizer by using minerals as raw materials and a production method thereof. The technical problem to be solved by the invention is that the middle element fertilizer has low middle element content, single nutrient, low utilization rate, cumbersome application and so on. A technical scheme adopted in the invention is as below: the mineral middle element fertilizer comprises the following raw materials by weight: 300 to 500 parts of calcined glauconite, 30 to 50 parts of sodium metasilicate, 150 to 300 parts of plant ash, 120 to 240 parts of quicklime, 140 to 220 parts of magnesium sulfate monohydrate and 8 to 15 parts of trace element fertilizer, wherein the calcined glauconite is made by calcining glauconite of which the silicon oxide content is 50 to 75 wt% at high temperature of 3500 to 4500 DEG C, and the trace element fertilizer is a mixture of fertilizers containing four trace elements such as B, Zn, Mo and Fe, respectively. The middle element fertilizer provided by the invention has the advantages of benefiting a whole year though one-time fertilization, being convenient for fertilization, and saving manpower, material and financial resources.

Description

technical field [0001] The invention specifically relates to a medium element fertilizer using minerals as raw materials and a production method thereof. Background technique [0002] The medium element fertilizer is also called the secondary constant element fertilizer, and it is called secondary fertilizer in English. It contains one or more compounds of the crop nutrients calcium, magnesium and sulfur, and the content needs to be indicated. Secondary constants are compared with the scale of production and application of major constants N, P, K. In China, it is commonly known as medium element fertilizer. In addition to providing crop nutrients, this type of fertilizer can also adjust the physical properties of the soil and promote agricultural production. For a long time, the production of medium-nutrient fertilizers has not been paid attention to by people. The reason is that some commonly used fertilizers, especially low-concentration fertilizers, contain calcium, ma...
