Abstract

The invention discloses fertilizer special for canola, which is prepared by raw materials such as 1-3 parts of composite envelope powder body, 4-6 parts of rosin, 5-8 parts of paraffin wax, 36-42 parts of urea, 15-18 parts of diammonium phosphate, 24-30 parts of potassium chloride, 1-2 parts of zinc sulfate, 0.5-1.5 parts of morning glory powder, 1-2 parts of radix stemonae powder and 0.5-1.5 parts of attapulgite through envelope technology according to part by weight, wherein the composite envelope powder body is prepared by the raw materials such as 1-2 parts of calcium carbonate, 1-2 parts of iron ore, 1-2 parts of dolomite, 1-2 parts of potassium feldspar, 2-4 parts of slag, 3-5 parts of peat soil and 1-2 parts of ailanthus leaf powder; according to the invention, each nutrient element needed for canola growth is matched reasonably so as to prepare composite fertilizer; in addition, the fertilizer is characterized by light quality, water retention, fertilizer maintenance and excellent slow release performance.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special fertilizer for rapeseed. Background technique [0002] Coated fertilizers are also called coated fertilizers and film fertilizers. Fertilizers made of quick-acting fertilizer granules wrapped with semi-permeable or impermeable film substances. Film-forming substances include plastics, resins, paraffin, polyethylene and elemental sulfur. The purpose of the coating is to slowly release the quick-acting nutrients in the coated fertilizer after it is applied to the soil, so as to prolong the fertilizer effect. The release rate depends on the type of coating, thickness, particle size, fertilizer solubility, soil temperature, soil water content, and soil microbial activity. It is suitable for crops with high economic value, long growth period, large amount of fertilizer but inconvenient to fertilize in batches, and high temperature, rainy areas or irrigated areas where nutrients...
