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

[0056] Embodiment 1: carbonization furnace

[0057] The carbonization furnace consists of a furnace body 1, a burner 4, an exhaust port 5, and a discharge port 2, as shown in Figure 1. The body of the carbonization furnace is made of 8mm thick double-layer steel plate, and asbestos silk is used as the middle insulation interlayer. The furnace body is in the shape of a cuboid. The furnace body is semi-closed, with no cover on the top. The specific parameters of the special carbonization furnace for corncob granular carbon are shown in the table below. At the bottom of the narrower side of the furnace body 1, there is a discharge opening 2 for discharging and igniting the burner from the discharge opening. The outlet is square or semicircular. The size of the discharge port can be designed according to the volume of the furnace body. In principle, it is determined that the furnace body does not automatically drop after the material is loaded. There is no sliding door outsid...

Embodiment 2

[0060] Embodiment 2 corn cob granular carbon production method

[0061] The method for producing corncob granular carbon using the carbonization furnace described in Example 1 includes steps such as material selection, material processing, furnace charging for carbonization, cooling out of the furnace, and metering and packaging.

[0062] Material selection: Naturally air-dry the corncobs of agricultural by-products to reduce the water content to below 20%.

[0063] Material processing: use any crushing method in the prior art to process and crush the above-mentioned qualified corncobs, and the diameter of the crushed corncobs is 2-10mm. The crushed corn cob particles can be sieved, and the corn cob particles that do not meet the requirements can be reprocessed.

[0064] Furnace charging and carbonization: put the processed corn cob particles into the furnace body, and the initial amount of material added is to cover the burner by 10-25 cm. Ignite the igniter in the ignition...

Embodiment 3

[0067] The production technology of embodiment 3 charcoal-based slow-release soybean special fertilizers

[0068] 80 kg of urea (containing N46%), monoammonium phosphate (containing N11%, P 2 o 5 46%) 280 kg, 300 kg of corn cob granular carbon particles, potassium sulfate (containing K 2 O50%) 230 kg, zinc sulfate (20% to 23% zinc) 10 kg, borax (11% boron) 22 kg, molybdenum fertilizer (10% molybdenum) 8 kg, binder 70 kg, mixed with ZLC -300 type mixer (commonly used machinery in the process of fertilizer preparation) and KP-300 type organic fertilizer granulator (commonly used machine in the process of fertilizer preparation) for pressure granulation, and other types of mixers and granulators can also be used for mixing Granulate. The binder is acidic bentonite with a pH of 5.5-6.5. The particle size of the corn cob 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 special carbon-based slow-release soybean fertilizer and a preparation method thereof. Background technique [0002] Soybean is the main source of plant protein nutrition for Chinese people, and it is a raw material crop for many important physiologically active substances; soybean oil is the main source of high-quality oil nutrition for Chinese people; soybean meal is an indispensable source of protein feed for aquaculture; soybean due to the nitrogen fixation effect of root nodules , is an important crop of ecological agriculture and organic agriculture. Soybean production has a crucial role to play. However, due to the limited arable land area in our country, which is mainly used for rice, wheat, soybean and other crops, it is difficult to increase the soybean output rapidly, the total output is seriously insufficient, and the per unit yield is low. [0003] Fertilize...
