preparation example Construction

[0043] The preparation process of carbon-based slow-release potato special fertilizer includes mixing various components and granulating with a particle size of 3.35 to 5.0 mm.

[0044] The carbon-based slow-release potato special fertilizer provided by the invention is simple to use and can be used as a special disposable base fertilizer for potato. The preferred application rate of one-time base fertilizer is 40 kg / mu. When sowing, it is applied mechanically at a depth of 12-15 cm under the seed or at a depth of 5-10 cm between two holes without topdressing.

[0045] Preferably, the present invention uses the semi-closed particle carbonization furnace described in the Chinese invention patent with the patent number ZL200710086505.4 (such as figure 1 , 2 (Shown) to produce biomass granular charcoal, as described in the patent, the semi-closed granular carbonization furnace uses an anoxic dry distillation decomposition process under sub-high temperature conditions to produce agricul...

Embodiment 1

[0047] Example 1 Exemplary production method of corncob granular charcoal

[0048] This embodiment exemplarily describes the method of producing corn cob granular charcoal using the semi-closed granular carbonization furnace described in the Chinese invention patent with the patent number ZL200710086505.4, including material selection, material processing, furnace charging, cooling and discharging, Steps such as measuring and packaging, but not limited to this.

[0049] Material selection: Naturally air-dry the corncob of agricultural and sideline products to reduce the moisture content to below 20%.

[0050] Material processing: using any crushing method in the prior art to process and crush the above-mentioned qualified corncob particles, the diameter of the crushed corncob particles is 2-10mm. The crushed corn cob particles can be screened through a sieve, and the corn cob particles that do not meet the requirements can be reprocessed.

[0051] Furnace carbonization: Load the proc...

Embodiment 2

[0055] Example 2 Production method of peanut shell granular carbon

[0056] This embodiment exemplarily describes the method for producing peanut shell granular charcoal using the semi-closed granular carbonization furnace described in the Chinese invention patent with the patent number ZL200710086505.4, including material selection, furnace charging and carbonization, cooling and discharging, metering and packaging, etc. Steps, but not limited to this.

[0057] Material selection: Naturally air-dry the peanut shells of agricultural and sideline products to reduce the water content to below 20%.

[0058] Furnace carbonization: Put the cleaned peanut shells into the furnace body. The initial amount of material added should cover the burner by 10-25 cm. Ignite the ignitor in the burner ignition plate. The pilot fuel is diesel. After the material is ignited, it will continue to spontaneously ignite without external heating source. The material is carbonized under anoxic conditions a...

Abstract

The invention relates to the field of agricultural chemistry, in particular relates to a carbon-based controlled-release fertilizer special for potato and a preparation method thereof. The environment-friendly efficient carbon-based controlled-release fertilizer special for the potato is a long-acting granular-carbon-based compound fertilizer which is prepared from waste agriculture and forestry biomasses such as corn core, peanut shell, rice shell, edible fungi substrate and the like, wherein the biological granular carbon is black carbon powder granules (carbon black) which is formed by imperfect combustion of biomasses under anaerobic condition and has various features similar to those of soil humus (acid); and the biological granular carbon has strong capabilities of absorbing and retaining nutrition and moisture, can stimulate growth of crops and has good controlled-release effect on NPK, thus the prepared controlled-release fertilizer only needs to be applied once in the full growth and development period of potatoes, has the characteristics of increasing soil fertility, improving soil structure and the like, is efficient and environment-friendly, and has a wide application prospect.

Description

Technical field [0001] The invention relates to the field of agricultural chemistry, in particular to a carbon-based slow-release potato special fertilizer and a preparation method thereof. Background technique [0002] Potatoes are rich in nutrients and are both food and vegetable foods, high-quality feeds, and raw materials for food processing and various industries. Potatoes have a wide range of adaptation, short growth period, strong disaster resistance, low requirements for land quality, and extremely low planting costs. Vigorously developing the potato planting industry, whether it is to solve the problem of poverty alleviation in the cold and poor areas, or to realize the desire to become rich in the developed areas, is of very important significance and occupies an extremely important position in the national economy and social development. [0003] my country is a big potato producer, and its planting area ranks among the top in the world, but its yield per unit area is o...
