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. CN 101081773A "Potato Compound Fertilizer" prepared a kind of potato compound fertilizer according to the law of potato fertilizer requirement, which has a better effect of increasing production, but did not consider the demand law of medium and trace elements and the effect of organic fertilizer and beneficial fungi. Low utilization rate of fertilizers, waste of resources and pollution of the environment
Publication No. CN 101177366A "Special Controlled-release Fertilizer for Potatoes with Sulfur-Added Resin Coating and Its Preparation Method" uses sulfur-added resin-coated fertilizers with different coating thicknesses to mix and prepare BB fertilizers (blend fertilizers) for controlled-release potatoes. The special controlled-release 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

[0063] Weigh 400kg of raw materials potassium sulfate, 182kg of monoammonium phosphate, 150kg of humic acid, 15kg of ferrous sulfate, 10kg of zinc sulfate, 10kg of borax, and 9kg of ammonium molybdate according to the ratio, put them into the mixing tank for mixing, and send them to the drum granulator , spray a small amount of steam into the material of the granulation drum through the steam nozzle, and spray 174kg of molten urea into the material of the granulation drum at the same time, heat the material to 45°C, and form balls through the continuous rotation of the granulation drum. Send the balled material into the drying drum, dry it with hot air at 70°C, cool the dried material, sieve, pack, and add 50kg of biological additives during packing to get the finished product.

[0064] The total nutrient content of the above-mentioned multi-element biological humic acid special fertilizer for potatoes is 38%, of which nitrogen (N) is 10%, phosphorus pentoxide (P 2 o 5 ) 8%, ...

Embodiment 2

[0066] According to the ratio, raw materials urea 298.36kg, potassium sulfate 400kg, monoammonium phosphate 113.64kg, biological additive 50kg, humic acid 100kg, ferrous sulfate 15kg, zinc sulfate 8kg, borax 8kg, ammonium molybdate 7kg. Production technology is with embodiment 1.

[0067] The total nutrient content of the above-mentioned multi-element biological humic acid special fertilizer for potatoes 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%.

[0068] 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...

Abstract

The invention discloses multi-element biologic humic acid fertilizer special for potatoes and a preparation method thereof, which relate to the technical field of mixed fertilizers. The multi-element biologic humic acid is prepared in the way that urea, potassium sulfate, monoammonium phosphate, biological additive, humic acid, ferrous sulfate, zinc sulfate, sodium borate and ammonium molybdate with set components are mixed and the multi-element biologic humic acid is prepared by conducting pelleting, drying, cooling, screening and packaging on the mixture. The fertilizer special for potatoes has the advantages of being low in cost, high in fertilizer utilization ratio, complete and reasonable in nutrient, free of environment pollution and remarkable in yield increase.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a multi-element biological humic acid special fertilizer for potatoes. Background technique [0002] Potato is one of the important food crops among non-cereal crops, which has the characteristics of high yield and stable yield. my country's potato cultivation area is relatively large, accounting for 20%-25% of the world's total, and it is an important food and vegetable dual-purpose crop. [0003] The growth period of potato is divided into seedling period, tuber formation period, tuber growth period, starch accumulation period and maturity period. The fastest absorption period of nitrogen and phosphorus is the tuber formation period, and the fast absorption period of potassium is the tuber enlargement period. In the seedling stage, stems and leaves are the growth centers, nitrogen, phosphorus, and potassium are distributed in stems and leaves, nitrogen, phosphoru...
