Problems solved by technology

Because soybeans meet the needs by absorbing nitrogen contained in soil and fertilizers and symbiotic nitrogen fixation by rhizobia, it is necessary to pay attention to the relationship between the two when applying chemical nitrogen fertilizers. If the amount of chemical fertilizer nitrogen is too much, the number of root nodules Reduced nitrogen fixation rate will increase the cost of soybean production

Embodiment 1

[0066] A new type of green high-efficiency multifunctional humic acid soybean fertilizer, nitrogen, phosphorus and potassium (N-P 2 o 5 -K 2 O) contents are 15%, 20%, 10% respectively, all are percentages by mass.

[0067] 217 parts of urea, 454 parts of monoammonium phosphate, 161 parts of potassium chloride, 60 parts of humic acid, 10 parts of EDTA chelated zinc, 10 parts of EDTA chelated iron, 10 parts of EDTA chelated boron, 10 parts of magnesium sulfate, 5 parts Ammonium molybdate and 63 parts of additives are measured and mixed. After mixing and stirring evenly, they enter the granulator, and steam is passed into the granulator to form pellets. The material temperature is controlled at 35°C-45°C, and then enters the second stage. First drying (the outlet material temperature is controlled at 60°C-75°C) and the first cooling, after cooling, it is screened, and the semi-finished product after screening is then dried for the second time (the outlet material temperature is...

Abstract

The invention discloses a novel green efficient multifunctional humic acid special fertilizer for soybean and preparation method thereof. The invention takes carbamide, monoammonium phosphate, potassium chloride, humic acid, EDTA chelated zinc, EDTA chelated ferrum, EDTA chelated boron, magnesium sulfate, ammonium molybdate and additives in set proportion as the raw materials; and finished product of fertilizer for soybean can be obtained through the processes of mixing, stirring, pelleting, drying and cooling for the second time, screening, enveloping, metering and packaging. Through adopting the special fertilizer for soybean, the quality of the soybean is obviously improved, and the production increase is remarkably realized, thus a remarkable economic effect is obtained.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a novel green high-efficiency multifunctional humic acid special fertilizer for soybeans and a preparation method thereof. Background technique [0002] Soybean is not only a food crop, but also an important oil crop. Soybeans need more fertilizer, and absorb more nitrogen, phosphorus and potassium than rice and corn. According to research, every 100 kilograms of soybeans produced absorb about 7-9.5 kilograms of nitrogen, 1.3-2.0 kilograms of phosphorus, and 2-3.7 kilograms of potassium. There are 1 kg of magnesium, 0.67 kg of sulfur, 0.308 g of molybdenum and a certain amount of trace elements. Because soybeans meet the needs by absorbing nitrogen contained in soil and fertilizers and symbiotic nitrogen fixation by rhizobia, it is necessary to pay attention to the relationship between the two when applying chemical nitrogen fertilizers. If the amount of chemical fe...
