Seaweed nutrient containing efficient special fertilizer for oilseed rapes and preparation method thereof

Abstract

The invention relates to a fertilizer for agricultural production, and specifically relates to a seaweed nutrient containing efficient special fertilizer for oilseed rapes and a preparation method thereof. The fertilizer is prepared by taking urea, calcium superphosphate, zinc sulfate, monoammonium phosphate, zinc oxide, boric acid, potassium chloride, seaweed extract and seaweed extract residues as raw materials through using special processes. Compared with existing oilseed rape fertilizers, the fertilizer disclosed by the invention is complete in nutrients, reasonable in fertilizer proportion and high in fertilizer efficiency utilization rate, and the fertilizer is also suitable for being absorbed by rapeseed crops and can significantly increase the yield of rapeseed rapes; the fertilizer can provide needed nutrients for different growth stages of oilseed rapes, thereby controlling high fertilizer efficiency, and increasing economic benefits.

Description

technical field [0001] The invention relates to a fertilizer for agricultural production, in particular to a high-efficiency rape special fertilizer containing seaweed nutrients and a preparation method thereof. Background technique [0002] Rapeseed is the most common winter crop planted in the Yangtze River Basin. It is the main oil crop in my country. At present, the perennial planting area is 7 to 8 million hectares. About 60% of the domestically produced edible vegetable oil comes from rapeseed. Increasing the output of rapeseed is to meet the needs of the people. An important measure of demand, fertilizers applied to the soil have problems such as loss and fixation, which cause loss and failure. Therefore, according to the nutrient absorption characteristics of rapeseed, combined with the behavior of various nutrient elements in the soil to achieve scientific and rational application is the key to improving fertilizer use efficiency, reducing fertilizer input costs, and...

Problems solved by technology

[0003] At present, the recommended way of fertilizing rapeseed is that 70%~80% of nitrogen fertilizer, all of phosphorus fertilizer, potassium fertilizer and boron fertilizer are applied as base fertilizer when sowing or transplanting, and only the remaining nitrogen fertilizer is used as top dressing once or twice, and In actual production, many farmers plant rapeseed and only apply base fertilizer once

Although rapeseed is very sensitive to nutrient deficiency at the seedling stage, the absorption of nutrients is limited at this time due to the small growth. Leaking with rainwater, or being fixed by the soil, and when rapeseed needs a lot of nutrients in the vegetative growth and reproductive growth periods, there is often a phenomenon of insufficient fertilizer supply, which affects the yield and quality of rapeseed
