preparation example Construction

[0035] The present invention provides the preparation method of the medium and trace element granular fertilizer described in the above scheme, comprising the following steps:

[0036] 1) mixing oyster shell powder, calcined oyster shell powder and magnesium sulfate monohydrate to obtain a mixture;

[0037] 2) Spray the seaweed active substance on the mixture in the step 1), carry out disc granulation, and let stand to obtain medium and trace element granule fertilizer.

[0038] In the present invention, the mixed material is obtained by mixing oyster shell powder, calcined oyster shell powder and magnesium sulfate monohydrate.

[0039]In the present invention, after the mixed material is obtained, the seaweed active substance is sprayed on the mixed material, disc granulated, and left to stand to obtain medium and trace element granular fertilizer; the temperature of the disc granulated is 16-25°C, preferably 20°C The rotating speed of the disc granulation is preferably 10~2...

Abstract

The invention provides a medium / trace element granular fertilizer and belongs to the technical field of medium / trace element fertilizers. The medium / trace element granular fertilizer comprises the following raw materials in parts by weight: 70-92 parts of oyster shell powder, 5-10 parts of calcined oyster shell powder, 10-40 parts of magnesium sulfate monohydrate and 0.5-6 parts of an alga activesubstance. The medium / trace element granular fertilizer provided by the invention is comprehensive in medium / trace element type, good in effectiveness, capable of replenishing medium / trace elements carried away by crops from soil in time and comprehensively, and thus has good effects that a healthy environment is provided for crops to grow, the nutrition is balanced, the yield of crops is increased and the quality is improved. In addition, the oyster shell powder in the medium / trace element granular fertilizer provided by the invention is of a micro hole structure, microbial population structures of soil can be regulated, the number of beneficial bacteria can be increased, meanwhile, plant root systems can be developed, plants can grow strongly, the crop resistance can be improved, and theyield can be increased. In addition, together with a basic fertilizer, the medium / trace element granular fertilizer provided by the invention can be used in modes of bottom application and throwing,and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of medium and trace element fertilizers, in particular to a medium and trace element granular fertilizer and a preparation method thereof. Background technique [0002] The secondary elements refer to the nutrient elements that are required in the growth process of crops, which are inferior to nitrogen, phosphorus, and potassium but higher than trace elements. Medium elements generally account for 0.1% to 1% of the dry weight of crops, usually referring to calcium, magnesium, and sulfur. In the traditional classification of nutrient elements, calcium, magnesium, and sulfur are often classified as macronutrients, mainly because the absorption of these three elements by plants is also very high, sometimes exceeding macronutrients, especially phosphorus. Since the companion ions of soil and some fertilizers often contain a large amount of calcium, magnesium, and sulfur, people often ignore the importance of th...
