Embodiment 1

[0016] A kind of high-efficiency rape special fertilizer containing seaweed nutrient components of the present invention, its raw material ratio mass parts are as follows:

[0017] Urea 30, superphosphate 5, zinc sulfate 2

[0018] Monoammonium Phosphate 4, Zinc Oxide 26, Boric Acid 1, Potassium Chloride 24, Monoammonium Phosphate 20, Potassium Chloride 4, Seaweed Extract 3, Seaweed Extract Residue 40

[0019] The seaweed is a mixture of one or more of kelp, horsetail, and Ascophyllum nodosum, and the seaweed extract is prepared by the following method. After the above seaweed is crushed, it is immersed in 1-2 times the weight of clear water, and the temperature is raised to 70-80°C, use potassium hydroxide to adjust the pH value to 8-8.5, keep warm and stir for 30 minutes, cool to room temperature and filter through a 200-mesh silk sieve to obtain the primary filtrate and primary filter residue; take the primary filtrate equal weight of water and inject the primary filter res...

Embodiment 2

[0025] The high-efficiency rapeseed special fertilizer containing seaweed nutrient components of the present invention has the quality components of its raw material ratio as follows:

[0026] Urea 45, superphosphate 9, zinc sulfate 3

[0027] Zinc oxide 34, boric acid 2 potassium chloride 16,

[0028] Monoammonium phosphate 24, seaweed extract 5, seaweed extraction residue 60, and the rest are the same as in Example 1.

Embodiment 3

[0030] The high-efficiency rapeseed special fertilizer containing seaweed nutrient components of the present invention has the quality components of its raw material ratio as follows:

[0031] Urea 43, calcium superphosphate 8, zinc sulfate 2, monoammonium phosphate 5, zinc oxide 30, boric acid 1.5 potassium chloride 18, monoammonium phosphate 26, potassium chloride 5, seaweed extract 4, seaweed extraction residue 50, and the rest are the same Example 1.

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...
