Embodiment 1

[0043] A slow-release oxidant with calcium peroxide as matrix nano-organic bentonite and solid paraffin as coating, which is made of the following raw materials in parts by weight:

[0044]

[0045]

[0046] A kind of preparation method that takes calcium peroxide as matrix nano-organic bentonite and solid paraffin as coating slow-release oxidant, its steps are:

[0047] A.60% calcium peroxide raw powder granulation:

[0048] ①Granulation: Adjust the inclination angle of the disk granulator to 60°, the speed to 30r / min, and the heating device to 40-50°C; take 1kg of calcium peroxide raw powder and divide it into 10 equal parts. Take one part and put it in the disc, quickly use water mist to moisten it and form small particles, the particle size of which is about 0.5mm, take it out for use, repeat the above steps 5 or 7 or 10 or 15 times, until all 10 parts of powder are complete The granulation is completed.

[0049] ②Granulation: adjust the inclination angle of the di...

Abstract

The invention discloses a slow-release oxidizing agent with calcium peroxide as a matrix and nanometer organobentonite-paraffin as envelopes and a preparation method. The slow-release oxidizing agent is prepared from 60% calcium peroxide, an adhesive, attapulgite, nanometer organobentonite and solid paraffin in proportion in steps as follows: A, 60% calcium peroxide is mixed uniformly with the adhesive and the attapulgite to be granulated, and the size of each granule ranges from 3 mm to 5 mm; B, the nanometer organobentonite and the solid paraffin are added in proportion according to the mass of the granules in the step A; the granules in the step A are enveloped with the raw materials in B, and the slow-release oxidizing agent is prepared after drying. The formula is reasonable, the method is easy to implement, operation is simple, the problem about the oxygen release time of calcium peroxide in a gleization rice field can be effectively solved, the rice growing environment of the gleization rice field is improved, the slow-release agent is unparalleled to common oxidizing agents in improvement of acidic gleization rice soil in the southern area and has wide raw material sources and broad popularization and application prospect, a processing process is simple and convenient, and the operation method is easy to implement.

Description

technical field [0001] The invention belongs to the fields of agricultural ecology, soil improvement and plant nutrition control, and more specifically relates to a slow-release oxidant with calcium peroxide as the matrix, nano-organic bentonite and solid paraffin as the coating, and also relates to a peroxidized Calcium as the matrix nano-organic bentonite and solid paraffin as the preparation method of the slow-release oxidant, the slow-release oxidant can effectively reduce the toxic reducing substances in the gleization paddy field, and can provide oxygen for the rice, and can also improve the acid gleization The soil pH of paddy field improves the growth environment of gleized paddy rice, and the prepared slow-release oxidant is suitable for the improvement of gleized paddy field when rice is planted in vast gleized rice areas. Background technique [0002] The gleogenic paddy field is the most common low-yielding field in southern my country, widely distributed in the ...
