Problems solved by technology

However, the production, storage and use of biological fertilizers are very strict. If they are not handled properly, it is easy to bring harmful bacteria that are not good for ginseng; or if they are stored for too long, the activity of biological fertilizers will be lost.
This not only increases the cost of bio-fertilizer, but also limits the promotion and application of bio-fertilizer

Embodiment 1

[0024] Weigh 1000g of air-dried peat with a humic acid content of more than 20% and a particle size of less than 2mm, add 1500ml of 30% nitric acid, stir evenly, heat to 50°C, react for 25min, and filter to obtain the crude nitrohumic acid filtrate. Acid: urea=1:1 weight ratio, add urea to the filtrate, heat to 70°C, and react for 1.5 hours to obtain nitrohumic acid urea complex. According to the following mass ratio: complex 100g, add calcium magnesium phosphate fertilizer 8g, adjust pH to 7 with potassium hydroxide, heat to 80°C again, then add borax 0.01g, zinc sulfate 0.01g, manganese sulfate 0.01g, drought resistance agent The biodegradable superabsorbent resin is crushed to 1~2mm (0.05g), mixed evenly, and granulated for 3 minutes. Dry at 70°C for 20min.

Embodiment 2

[0026] Weigh 1000g of air-dried lignite with a humic acid content of more than 20% and a particle size of less than 2mm, add 2000ml of 30% nitric acid, stir evenly, heat to 60°C, react for 30min, and filter to obtain the crude nitro humic acid filtrate. Humic acid: urea = 1:1 weight ratio, add urea to the filtrate, heat to 80°C, and react for 2 hours to prepare nitro humic acid urea complex. According to the following ratio: complex 100g, add calcium magnesium phosphate fertilizer 8g, adjust pH to 8.0 with potassium hydroxide, heat to 80°C, then add borax 0.03g, zinc sulfate 0.015g, manganese sulfate 0.015g, drought resistance agent 0.07g, Mix well and granulate for 7 minutes. Dry at 110°C for 25min.

Embodiment 3

[0028] Weigh 1000g of air-dried weathered coal with a humic acid content of more than 20% and a particle size of less than 2mm, add 3000ml of 30% nitric acid, stir evenly, heat to 70°C, react for 30min, and filter to obtain the crude nitrohumic acid filtrate. Base humic acid: urea=1:2 weight ratio, add urea to the filtrate, heat to 85 ° C, react for 2.5 hours, and prepare nitro humic acid urea complex. According to the following ratio: 100g of complex, add 10g of calcium magnesium phosphate fertilizer, adjust pH to 8.5 with potassium hydroxide, heat to 85°C, then add 0.02g of borax, 0.05g of zinc sulfate, 0.02g of manganese sulfate, 0.1g of drought resistance agent, Mix well, send to granulator, granulate for 10 minutes. Dry at 120°C for 30min.

Abstract

A special ginseng composite fertilizer and its production are disclosed. The process is carried out by complexing humus acid with urea to form long-lasting urea as controlled-release fertilizer, adding into caustic potash while dissolving under basic condition and adding into phosphate fertilizer, magnesium fertilizer, boron fertilizer, zinc fertilizer, manganese fertilizer and drought-resisting agent. It can supply ginseng and microbial pool with nutrients, improve ginseng root development and increase its quality and pest-resistance. It's efficient, simple, stable, convenient and cheap.

Description

technical field [0001] The invention belongs to mixed fertilizers, in particular to a special compound fertilizer for ginseng and a preparation method thereof. Background technique [0002] Fertilizer plays an important role in my country's food safety and sustainable development. Special fertilizers are formulated according to the specific soil environment and specific crop varieties. It is highly targeted and regional, and can avoid waste of fertilizer use. It has obvious advantages in the future development of fertilizers. [0003] Ginseng is a perennial medicinal plant that has been widely used in healthcare. During the growth process of ginseng for many years, it needs more nutrients, especially potassium fertilizer, nitrogen fertilizer and medium and trace elements. Therefore, if the land where ginseng has been cultivated, it is difficult to directly use it for other purposes if it does not prepare the land and cultivate fertility; and ginseng During the growth proce...
