Embodiment 1

[0040] Embodiment 1 (by weight, the same below)

[0041] The biochar (dry basis) derived from straw was crushed and passed through a 60-mesh sieve, the clay was crushed to ≤100 mesh, and the granular chemical fertilizer was crushed through a 60-mesh sieve, and finally 20 parts of biochar (dry basis weight), 10 10 parts of urea, 30 parts of potassium dihydrogen phosphate, 20 parts of potassium sulfate, 10 parts of medical stone, and 10 parts of clay are added to the drum granulation equipment for mixing and granulation. That is, get N:P 2 o 5 :K 2 O=4.6:15.6:19.2, N+P 2 o 5 +K 2 O≥39.4% granular special compound fertilizer.

[0042] Test setup:

[0043] There are 3 treatments of special compound fertilizer, compound fertilizer and no fertilizer, compound fertilizer N:P 2 o 5 :K 2 O is the same as the special compound fertilizer, the compound fertilizer is a combination of urea, potassium dihydrogen phosphate and potassium sulfate, and each treatment is repeated 6 time...

Embodiment 2

[0045] Crush the biochar (dry basis) derived from straw and pass through a 60-mesh sieve, crush the clay to ≤100 mesh, and at the same time crush the granular chemical fertilizer through a 60-mesh sieve, and finally mix 20 parts of biochar, 10 parts of urea, and 35 parts of Potassium dihydrogen phosphate, 10 parts of potassium sulfate, 15 parts of medical stone, and 10 parts of clay are added to the drum granulation equipment to mix and granulate. That is, get N:P 2 o 5 :K 2 O=4.6:18.2:16.4, N+P 2 o 5 +K 2 O≥39.2% granular special compound fertilizer.

[0046] Test setup:

[0047] There are 3 treatments of special compound fertilizer, compound fertilizer and no fertilizer, compound fertilizer N:P 2 o 5 :K 2 O is the same as the special fertilizer, and the compound fertilizer is a combination of urea, potassium dihydrogen phosphate and potassium sulfate, and each treatment is repeated 6 times. Adopt local typical soil (brown soil) in Liaoning Province, use 18 plastic ...

Embodiment 3

[0049] Crush the biochar (dry basis) derived from straw and pass through a 60-mesh sieve, crush the clay to ≤100 mesh, and at the same time crush the granular chemical fertilizer through a 60-mesh sieve, and finally mix 20 parts of biochar, 10 parts of urea, and 35 parts of Potassium dihydrogen phosphate, 15 parts of potassium sulfate, 10 parts of medical stone, and 10 parts of clay are added to the drum granulation equipment to mix and granulate. That is, get N:P 2 o 5 :K 2 O=4.6:18.2:18.9, N+P 2 o 5 +K 2 O≥41.7% granular special compound fertilizer.

[0050] Experimental setup:

[0051] There are 3 treatments of special compound fertilizer, compound fertilizer and no fertilizer, and the compound fertilizer N:P 2 o 5 :K 2 O is the same as the special compound fertilizer, the compound fertilizer is a combination of urea, potassium dihydrogen phosphate and potassium sulfate, and each treatment is repeated 6 times. Adopt local typical soil (brown soil) in Liaoning Prov...

Abstract

The invention relates to the technical field of biological carbon fertilizers, in particular to a biological-carbon-based compound fertilizer which can prolong the nitrogen fertilizer efficacy period, reduce phosphatic fertilizer leaching loss, increase the utilization rates of nitrogen and phosphorus and sufficiently meet the requirements of growth of bulb flowers, and has the functions of resisting drought, preserving soil moisture and improving soil, and application of the compound fertilizer. The compound fertilizer is prepared from 10-30% of biological carbon (dry basis), 45-60% of chemical fertilizer, 10-20% of medical stone and 10-15% of clay. The chemical fertilizer is preferentially prepared from 10-20% of urea, 25-40% of monopotassium phosphate and 10-20% of potassium sulphate. The raw materials are stirred and dried according to the proportion, sent into a granulation system to be granulated and dried (smaller than 10%), and then the compound fertilizer can be obtained. The biological-carbon-based compound fertilizer is simple and feasible in production process, small in investment, rapid in effect, high in agriculture yield, low in cost, suitable for being applied as base fertilizer for bulb flowers and capable of being widely applied to various types of soil in arid and semi-arid areas, and has wide market aspects and good social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a special compound fertilizer for bulbous flowers and a preparation method thereof. Background technique [0002] Due to factors such as volatilization, leaching and soil fixation, the utilization rate of nitrogen fertilizer in traditional chemical fertilizers has been low. The seasonal utilization rate of nitrogen fertilizer is only 30% to 40%, and the seasonal utilization rate of phosphorus fertilizer is only about 10% to 20%. The elements are lower, and it is difficult to fully exert its effect when applied in the current season. The low utilization rate of fertilizers not only leads to poor yield and quality improvement of crops, but also reduces economic benefits, and may also cause a series of ecological and environmental problems. Through industrial means, the production of biochar compound fertilizer characterized by high utilization rate and high environmental safet...
