Problems solved by technology

[0006]In view of the above special fertilizer requirements of potatoes, there are not many special fertilizers for potatoes in China, and there are disadvantages such as low fertilizer utilization rate, time-consuming and labor-intensive pollution of soil and water ecological environment
Publication No. CN101081773A "Potato Compound Fertilizer" prepared a kind of potato compound fertilizer according to the law of potato fertilizer requirement. Low utilization rate, wasting resources and polluting the environment
Publication No. CN101177366A "Special Controlled-release Fertilizer for Potatoes Added with Sulfur and Resin and Its Preparation Method" uses sulfur-added resin-coated fertilizers with different coating thicknesses to mix and prepare special BB fertilizer (blend fertilizer) for potato controlled release. The special fertilizer has a long controlled-release period, obvious yield-increasing effect, and high fertilizer utilization rate, but the coating material is not easy to degrade in the soil, causing secondary pollution, and the special controlled-release fertilizer is expensive and difficult to promote

Embodiment 1

[0037] According to the ratio, 400kg of potassium sulfate, 182kg of monoammonium phosphate, 200kg of biochar, 15kg of ferrous sulfate, 10kg of zinc sulfate, 10kg of borax, and 9kg of ammonium molybdate are sent to the buffer tank through the tower elevator for mixing with 174kg of molten urine. , granulated by a special granulation nozzle, the granulated granules are cooled, screened, coated and powdered, and then enter the finished product silo, and then sent to the manipulator after automatic packaging and sewing to obtain the finished product.

[0038] The total nutrient content of the above-mentioned biomass charcoal-based potato special fertilizer is 38%, of which nitrogen (N) is 10%, phosphorus pentoxide (P 2 o 5 ) 8%, potassium oxide (K 2 O) 20%, biochar 20%, sulfur (S) 0.38%, iron (Fe) 0.30%, molybdenum (Mo) 0.49%, boron (B) 0.15%.

Embodiment 2

[0040] According to the ratio, the raw materials urea 298.36kg, potassium sulfate 400kg, monoammonium phosphate 113.64kg, biochar 150kg, ferrous sulfate 15kg, zinc sulfate 8kg, borax 8kg, ammonium molybdate 7kg. Production technology is with embodiment 1.

[0041] The total nutrient content of the above-mentioned biomass charcoal-based potato special fertilizer is 40%, of which nitrogen (N) is 15%, phosphorus pentoxide (P 2 o 5 ) 5%, potassium oxide (K 2 O) 20%, sulfur (S) 0.34%, iron (Fe) 0.30%, molybdenum (Mo) 0.38%, boron (B) 0.12%.

[0042] Fertilizer effect test example

[0043] The applicant has cooperated with 11 soil and fertilizer stations in some provinces and cities across the country to investigate the soil nutrient status of major potato production bases such as Surabaya in Shandong and Jinsha in Guizhou, and establish a soil nutrient database. A field demonstration test was carried out in a farmer's responsibility field in Jianan Village, Wenyang, Feicheng, S...

Abstract

The invention discloses a high tower biomass carbon-based fertilizer special for potatoes, and belongs to the technical field of agricultural compound fertilizer. The high tower biomass carbon-based fertilizer is prepared from urea, potassium sulphate, monoammonium phosphate, biological charcoal, ferrous sulfate, zinc sulfate, borax and ammonium molybdate. The high tower biomass carbon-based fertilizer is produced by adopting a high tower melt granulation technology and has the advantages of being low in cost, high in fertilizer utilization rate, full and reasonable in nutrient and free of environmental pollution compared with the prior art.

Description

technical field [0001] The invention relates to the technical field of agricultural compound fertilizers, in particular to a high-tower biomass charcoal-based potato special fertilizer. Background technique [0002] Potato is an annual herbaceous tuber plant of Solanaceae Solanaceae, which originated in the Andes Mountains of South America and is one of the four major crops in the world. Potato resources are very rich. At present, there are more than 100 potato-growing countries in the world, with a total cultivation area of ​​200×10 8 m 2 , my country is the largest potato producing country in the world, with the planting area and total output ranking first in the world. The annual potato planting area in my country is 46.7×10 8 m 2 About, the total annual output of fresh potatoes is 5500×10 4 t, the average unit yield is 1.18kg / m 2 . The planting areas are mainly distributed in Heilongjiang, Jilin, Inner Mongolia, Shanxi, Gansu, Qinghai, Yunnan, Guizhou, Sichuan and ...
