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, it is of great significance to develop an environmentally friendly and high-efficiency peanut slow-release special fertilizer with charcoal as the organic matter, and the prospect is broad.

Embodiment 1

[0047] Embodiment 1: carbonization furnace

[0048] 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

[0051] Embodiment 2 corn cob granular carbon production method

[0052] 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.

[0053] Material selection: Naturally air-dry the corncobs of agricultural by-products to reduce the water content to below 20%.

[0054] 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.

[0055] 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

[0058] The production technology of embodiment 3 charcoal-based slow-release peanut special fertilizers

[0059] Ammonium sulfate (containing N20%) 110 kg, monoammonium phosphate (containing N11%, P 2 o 5 46%) 250 kg, 260 kg of corn cob granular carbon particles, potassium chloride (containing K 2 O60%) 160 kg, potassium sulfate (containing K 2 O50%) 90 kilograms, 10 kilograms of zinc sulfate (containing zinc 20%~23%), 20 kilograms of borax (containing boron 11%), 100 kilograms of binding agent are mixed, use ZLC-300 type mixer (commonly used in the fertilizer preparation process) Machinery) and KP-300 organic fertilizer granulator (commonly used machinery in the fertilizer preparation process) for pressure granulation, and other types of mixers and granulators can also be used for mixed granulation. The binder is acid bentonite. 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 earthpea, which is characterized in that: the fertilizer comprises earthpea core grain carbon grain, ammonium sulphate, ammonium phosphate, zinc sulfate, kalium sulphate, potassium chlordide and borax. The present invention also relates to the produce method for the special fertilizer for a charry releasing earthpea. 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 earthpea, and then uses a moist soil or clay as the cement compound to prepare the grain-shaped special fertilizer for a charry releasing earthpea. 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 earthpea 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 earthpea.

Description

technical field [0001] The invention relates to the field of fertilizer preparation, in particular to a special carbon-based slow-release peanut fertilizer and a preparation method thereof. Background technique [0002] Peanut occupies an important position in my country's national economy. It is the main source of food oil for our people, the main source of plant protein for human beings, an important raw material for food and pharmaceutical industries, and an important agricultural product for my country's export earnings. Although my country's peanut production ranks first in the world, with the increase of industrial land, the area of ​​farmland has decreased sharply, especially grain production has been impacted, and the conflict of grain and oil competition for land is unavoidable; with the improvement of people's living standards, the demand for various oils, including peanut oil And the demand for peanut food will continue to increase, so increasing the yield per unit...
