The slow release layer is sprayed on the outer layer of the fertilizer layer.
The sustained-release layer also comprises a dispersant which accounts for 5% of the weight of the sustained-release layer and consists of the following components in parts by weight: 1 to 6 parts of peptone, 10 to 50 parts of phospholipid oil and 5 to 50 parts of fatty acid ester.
The fertilizer layer also comprises secondary elements and trace elements, wherein the secondary elements comprise magnesium fertilizer, calcium fertilizer and sulfur fertilizer, and the trace elements comprise iron fertilizer manganese fertilizer, copper fertilizer, boron fertilizer and zinc fertilizer.
The polypeptide urea comprises urea, aspartic acid and metalloprotease.
The production process for preparing the special slow-release organic fertilizer for wheat comprises the following steps:
a, weighing the fertilizer layer raw materials according to a ratio, breaking and stirring agglomerates with large volume in the fertilizer layer raw materials, fermenting the agglomerates in a closed tank, taking out the agglomerates, drying and crushing the agglomerates to 50-100 meshes to prepare fertilizer layer particles;
