Selenium-rich fertilizer for wheat cultivation and preparation method of selenium-rich fertilizer

Abstract

The invention discloses selenium-rich fertilizer for wheat cultivation. The fertilizer is prepared from the following raw materials in parts by weight: 0.4-1 part of magnesium nitrate, 3-4 parts of sucrose residues, 0.3-0.7 parts of selenium yeast, 4-6 parts of chlorella powder, 7-10 parts of turfy soil, 14-20 parts of coconut shell powder, 0.4-1 part of triethanolamine, 13-20 parts of camphor bark powder, 1-2 parts of shellfish fossils, 0.1-0.2 parts of narrow-leaved lindernia, 2-3 parts of sugarcane leaves, 0.2-1 part of ricinoleic acid, 17-20 parts of fishbone, 3-4 parts of potassium sulfate, 0.1-0.2 parts of zinc chloride, 4-6 parts of rapeseed cakes, 130-140 parts of urea, 10-14 parts of calcium sulfate and 20-30 parts of diammonium phosphate. The fertilizer is rich in selenium, can effectively increase the content of selenium in wheat and contains various trace elements, and a ball abrasive treated with an amide dispersion liquid can effectively reduce the content of heavy metal in soil and realizes a good sustained release effect.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a selenium-rich fertilizer for wheat planting and a preparation method thereof. Background technique [0002] Traditional chemical fertilizers lead to soil compaction, crop yield reduction, and damage to the ecological environment, especially the eutrophication of water bodies, which affects the health of humans and animals. For a long time, people have formed the status quo of partial application of chemical fertilizers and neglect of organic fertilizer application, which not only reduces soil productivity and crop quality, but also greatly damages the ecological environment. In this regard, the significance of how to reasonably and effectively combine chemical fertilizers with organic fertilizers made from organic wastes is not only to make full use of resources and improve comprehensive economic, social, and ecological benefits, but also to give Compound fertilizers have ...
