Problems solved by technology

Due to the rapid development of my country's agriculture, the output of food and other crops is increasing every year, and a large amount of nutrients are absorbed from the soil. Although the nitrogen, phosphorus and potassium elements are replenished in time, the silicon element is not replenished in time. The silicon element in the soil has been far away due to natural weathering. It is far from meeting the needs of crops and soil for silicon, and cannot maintain a balance

Embodiment 1

[0035] A kind of suspension silicon fertilizer, comprises Aoli silicon particle (containing silicon dioxide 72%) 30g, wetting agent MSR-TT12g; Dispersant MSD-511 4g; Thickener xanthan gum 0.2g, antifreeze agent propylene glycol 4g, water 159.8g.

[0036] The method for preparing above-mentioned suspended silicon fertilizer, refer to figure 1 , including the following steps:

[0037] 1) Add water to the high-speed shear 1, add "bio-silicon" and soak for 30 minutes, start the high-speed shear 1, adjust the speed to 200r / min, add the weighed wetting agent, dispersant, thickener in sequence, and shear Cut for 40 minutes;

[0038] 2) Add antifreeze to the high-speed shearing machine 1, continue to shear for 20min, and the shearing speed is 200r / min;

[0039] 3) After the shearing is completed, the sheared material is pumped into the primary sand mill 2 for grinding through the first pipeline pump 9, and the ground material enters the primary sand grinding storage tank 3;

Embodiment 2

[0044] The difference with embodiment 1 is:

[0045] A kind of suspension silicon fertilizer, comprises Aoli silicon granule (containing silicon dioxide 72%) 34g, wetting agent MSR-TT13g; Dispersant MSD-511 6g; Thickener xanthan gum 0.5g, antifreeze agent propylene glycol 6g, water 150.5g.

Embodiment 3

[0047] The difference with embodiment 1 is:

[0048]A kind of suspension silicon fertilizer, comprises Aoli silicon granule (containing silicon dioxide 72%) 40g, wetting agent MSR-TT14g; Dispersant MSD-511 8g; Thickener xanthan gum 0.8g, antifreeze agent propylene glycol 8g, water 139.2g.

[0049] The products prepared in Example 1, Example 2 and Example 3 were tested, the results are shown in the table below, the dispersion is good, and the particles reach the nanoscale.

Abstract

The invention relates to the technical field of fertilizers. The invention particularly provides a suspended silicon fertilizer as well as a preparation method and device thereof. The suspended silicon fertilizer comprises the following components in percentage by mass: 15%-20% of biological silicon, 1.0%-2.0% of a wetting agent, 2.0%-4.0% of a dispersing agent, 0.1%-0.4% of a thickening agent, 2.0%-4.0% of an anti-freezing agent and the balance of water, wherein the biological silicon is based on SiO2. Bio-silicon is sheared to a nanoscale by shearing, and ammonium ions are adsorbed by the formed silica colloid, immobilizing heavy metal ions. Meanwhile, the lost silicon element in the soil can be supplemented, and the requirement of crop growth can be satisfied.

Description

technical field [0001] The invention relates to the technical field of fertilizers, and in particular provides a suspended silicon fertilizer, a preparation method and a device, which can improve the utilization rate of available silicon in soil. Background technique [0002] Stable soil fertility is a necessary condition for sustainable agricultural development, and the balance between supply and demand of soil nutrients is an important basis for soil fertility. In developed countries, silicon has been listed as the fourth largest element after nitrogen, phosphorus, and potassium. In my country, silicon is defined as a beneficial element for crops. There is a large amount of evidence that silicon is an element for crop yield and quality. In the plants of silicon-loving crops, except for carbon, hydrogen, and oxygen, the silicon content is several times or even dozens of times that of other elements. The silicon needed by rice in its lifetime exceeds the total amount of nitr...
