Embodiment 1

[0019] The process flow of no-tillage slow-release willow special fertilizer preparation: urea + monoammonium phosphate + potassium chloride + Agri-sc→crushing, stirring→urea-formaldehyde spray→mixing and granulation→drying→sieving→packaging→finished product. Specific implementation: each ton of finished product is made of the following raw materials: 336 kg of urea (containing N46%), powdered monoammonium phosphate (containing N11%, P 2 o 5 44%) 250 kg, potassium chloride (contains K 2 O60%) 217kg, Agri-sc 10kg, diatomite compound fertilizer filler 85kg and chelating compound fertilizer anti-caking agent 2kg. After the above raw materials are fully mixed, then pulverized, stirred, and then sprayed with urea-formaldehyde solution (first inject the formaldehyde solution into the urine formaldehyde preparation tank through the formaldehyde solution pump, after stirring, inject the concentration of 96.5% molten urine through the molten urine pump Urea, make it fully mixed with...

Specific implementation: Each ton of finished product is made of the following raw materials: 330 kg of urea (containing N46%), powdered monoammonium phosphate (containing N11%, P 2 o 5 44%) 240 ㎏, potassium chloride (contains K 2 O60%) 237kg, Agri-sc15kg, diatomite composite fertilizer filler 66kg and 2kg chelating compound fertilizer anti-caking agent, after mixing the above raw materials thoroughly, then crushing, stirring, and then adding urea-formaldehyde liquid spray slurry (First inject the formaldehyde solution into the urine formaldehyde preparation tank through the formaldehyde solution pump, after stirring, inject 96.5% molten urea made of 130kg urea through the molten urine pump, make it fully mixed with the...

Embodiment 3

[0029] The process flow of no-tillage slow-release willow special fertilizer preparation: urea + monoammonium phosphate + potassium chloride + Agri-sc→crushing, stirring→urea-formaldehyde spray→mixing and granulation→drying→sieving→packaging→finished product. Specific implementation: each ton of finished product is made of the following raw materials: 350 kg of urea (containing N46%), powdered monoammonium phosphate (containing N11%, P 2 o 5 44%) 260 kg, potassium chloride (contains K 2O60%) 207kg, Agri-sc 5kg, diatomaceous earth compound fertilizer filler 86kg and 2kg chelating compound fertilizer anti-caking agent. First mix the above raw materials with 200kg of urea, then pulverize, stir, and then add urea-formaldehyde solution for spraying (first inject the formaldehyde solution into the urine formaldehyde preparation tank through the formaldehyde solution pump, and then inject it into the urine formaldehyde preparation tank through the molten urine pump after stirring. ...

Abstract

The invention belongs to the technical field of fertilizer preparation, and in particular relates to a non-tillage slow release fertilizer special for salix purpurea and a preparation method of the fertilizer. The non-tillage slow release fertilizer per ton is mainly prepared from the following raw materials: 330kg to 350kg of urea, 240kg to 260kg of powdery monoammonium phosphate, 207kg to 237kg of potassium chloride, 5kg to 15kg of Agri-sc and 90kg to 110kg of ureaformaldehyde. According to the non-tillage slow release fertilizer, the absorption of the salix purpurea to nutrient elements is promoted, so that the yield of salix purpurea is increased by more than 20%; the soil is loosened, so that the soil hardening is avoided; the plough layer is deepened, so that the abilities of water retention and fertilizer storage of the soil are improved; the release of the nutrient elements of the fertilizer is realized in dual effects of slow release and controlled release, so that the fertilizer efficiency is durable; the fertilizer is saved, so that the utilization rate of the fertilizer can be improved by 20% to 30%.

Description

(1) Technical field [0001] The invention belongs to the technical field of fertilizer manufacture, and in particular relates to a special fertilizer for no-tillage slow-release goji willow and a preparation method thereof. (2) Background technology [0002] Willow ( Salix integra Thunb . ) belongs to the genus Salix of Salicaceae, a deciduous shrub that grows in clusters for many years, and has a long history of cultivation in my country. At present, the production and output value of Qiliu in Shandong Province accounts for 80% of the country's total, while the output value of Qiliu in Linyi City accounts for 80% of that in Shandong Province. By the end of 2008, the total area of ​​willow planting in Linyi City had reached 279,000 mu, with an annual output of 200 million kilograms of high-quality dry strips. The city's annual export volume of willow products has accounted for 80% of the province's export volume, accounting for 80% of the national total. The export volume ...
