Problems solved by technology

At present, slow-release fertilizers at home and abroad are generally fertilizers that prolong the fertilizer effect through physical methods such as coating, wrapping, encapsulation, coating, etc., such as sulfur-coated urea, polymer-coated fertilizers, fertilizer-packed fertilizers wrapped in fertilizers, coated fertilizers, etc. Layer fertilizers, and wrapped fertilizers formed by mixing instant fertilizers with rubber emulsions and industrial and agricultural wastes. These fertilizers are expensive, and do not have rich pores, strong adsorption capacity, increase ground temperature, increase soil fertility, and improve soil structure. Therefore, the development of environmentally friendly and high-efficiency carbon-based soybean slow-release special fertilizer is of great significance and has a broad prospect. It can promote a virtuous circle in the soybean industry and increase soybean production and income.

Embodiment 1

[0057] Example 1: Carbonization furnace

[0058] The carbonization furnace consists of a furnace body 1, a burner 4, an exhaust port 5, and a discharge port 2, such as figure 1 Shown. The furnace body of the carbonization furnace is 8mm thick double-layer steel plate, with asbestos silk as the middle insulation interlayer. The furnace body is a rectangular parallelepiped shape. The furnace body is semi-closed and has no cover on the top. The specific parameters of the special carbonization furnace for corncob pellet carbon are shown in the following table. At the bottom of the narrow side of the furnace body 1, there is a discharge port 2 for discharging and igniting the burner from the discharge port. The discharge port is square or semicircular. The size of the discharge port can be designed according to the volume of the furnace body. In principle, the material does not drip automatically after the furnace body is loaded. There is no sliding door outside the discharge port. Th...

Embodiment 2

[0061] Example 2 Production method of corncob granular charcoal

[0062] The method for producing corn cob granular charcoal using the carbonization furnace described in Example 1 includes the steps of selecting materials, processing materials, charging furnace carbonization, cooling and discharging, and metering and packaging.

[0063] Material selection: Naturally air-dry the corncobs of agricultural and sideline products to reduce the moisture content to below 20%.

[0064] Material processing: using any crushing method in the prior art to process and crush the above qualified corn cobs, and the diameter of the crushed corn cob particles is 2-10 mm. The crushed corn cob particles can be sieved through a sieve, and the corn cob particles that do not meet the requirements can be reprocessed.

[0065] Furnace carbonization: The processed corncob pellets are loaded into the furnace body, and the initial amount of material is added to cover the burner by 10-25 cm. Ignite the ignitor...

[0068] Example 3 Production process of carbon-based slow-release soybean special fertilizer

[0069] Combine 80 kg of urea (containing N46%), monoammonium phosphate (containing N11%, P 2 O 5 46%) 280 kg, corn cob granular carbon particles 300 kg, potassium sulfate (including K 2 O50%) 230 kg, zinc sulfate (containing 20% ​​to 23% zinc) 10 kg, borax (containing 11% boron) 22 kg, molybdenum fertilizer (containing 10% molybdenum) 8 kg, binder 70 kg, mix with ZLC -300 mixer (common machinery in the fertilizer preparation process) and KP-300 organic fertilizer granulator (common machinery in the fertilizer preparation process) for pressure granulation, and other types of mixers and granulators can also be used for mixing Granulation. The binder is acid bentonite with pH 5.5-6.5. The particle size of the corncob granular carbon particles is preferably 80-100 mesh.

Abstract

The present invention relates to a special fertilizer for a charry releasing soybean, which is characterized in that: the fertilizer comprises earthpea core grain carbon grain, ammonium phosphate, zinc sulfate, kalium sulphate as well as one or more than one types amongcarbamide, ammonium sulphate, borax and molybdenum. The present invention also relates to the produce method for the special fertilizer for a charry releasing soybean. The method is to use the character of the earthpea core grain carbon grain with multi-micro hole and strong absorbing ability combined with nitrogen, phosphor, kalium and the other nutrition components required by the growth of the soybean, and then uses a moist soil or clay as the cement compound to prepare the grain-shaped special fertilizer for a charry releasing soybean. The preparation process for the fertilizer is simple, economical and environment-protective with one-off use; the fertilizer can satisfy the requirement of the nutrient for the whole growth period for the soybean effectively; the utilization ratio of the fertilizer is higher with saving the energy and the cost; the fertilizer is adaptable to be widely popularized in the large-scale production for the soybean.

Description

Technical field [0001] The invention relates to the field of fertilizer preparation, in particular to a carbon-based slow-release soybean special fertilizer and a preparation method thereof. Background technique [0002] Soybean is the main source of plant protein nutrition for the Chinese people, and it is the raw material for many important physiologically active substances; soybean oil is the main source of high-quality oil and nutrition for the Chinese people; soybean meal is the main source of protein feed that is indispensable for the aquaculture industry; soybeans are nitrogen-fixing due to root nodules It is an important crop of ecological agriculture and organic agriculture. Therefore, soybean production plays an important role. However, due to the limited area of ​​arable land in my country, which is mainly used for rice, wheat, soybeans and other crops, soybean production is difficult to increase rapidly, the total output is seriously insufficient, and the yield is low...
