Problems solved by technology

In the prior art, medical stone powder is used to increase the yield of crops, but the direct use of medical stone powder as a mineral fertilizer has the disadvantage that some inerts have relatively low activity and water solubility, and cannot be quickly absorbed by crops
In particular, the content of silica in medical stone is about 65%, but its water solubility is poor and its utilization rate is low.

Embodiment 1

[0029] 1: The number of medical stone mineral powder is 600-800 mesh, the medical stone mineral powder accounts for 65-70% of the total weight of the two, and the input ratio is 30-35% potassium hydroxide. Calcined at a high temperature of 1200-2000 for 1 hour while hot, quenched in water, settled, and concentrated to obtain silicate crystals containing various minerals. The silicate crystals were determined to contain silicon dioxide 60 %, and contains boron, selenium, and rare earth elements such as lanthanum, cerium, and more than 50 kinds of trace elements needed by plants.

[0030] 2. Take 600 kg of medical stone silicic acid crystals and put them into the reaction kettle, add 400 kg of water for more than 3 pressures (MP) 80-120°C to completely melt, filter to remove insoluble matter, and cool the liquid at room temperature for use.

Embodiment 2

[0044] Step 1: The medical stone mineral powder has a mesh number of 600 mesh, the medical stone mineral powder accounts for 65%, and the input accounts for 32% of potassium hydride dissolved water. Calcined at 1400°C for 1 hour while hot, quenched in water, settled, and concentrated to obtain silicate crystals containing various minerals. The silicate crystals contain 60% silicon dioxide as determined by microspectroscopy and X-ray diffractometer More than 50 kinds of trace elements required by plants such as boron, selenium, and rare earth elements lanthanum, cerium, etc.

[0045] Step 2: Take 600 kg of medical stone silicic acid crystals and put them into the reaction kettle, add 400 kg of water and over 3 pressures (MP) at 100°C to completely melt, filter to remove insoluble matter, and cool the liquid at room temperature for use.

[0046] Step 3: Two-way chelation: Take 15 kg of zinc oxide, 5 kg of manganese nitrate, and 3 kg of ammonium molybdate, dissolve them in 300°C ...

Abstract

The invention discloses a medical stone water-soluble mineral silicon fertilizer which includes a medical stone silicate solution. The medical stone silicate solution is prepared with medical stone mineral powder and a hydroxide according to a weight ratio of (6-7):(3-4) and through high-temperature calcination at 1200-2000 DEG C for 0.5-3 h to obtain medical stone silicate, and then adding water to dissolving the medical stone silicate to obtain the fertilizer. According to the embodiment in the invention, by means of high-temperature calcination and special proportion of the medical stone mineral powder and the hydroxide, in the medical stone water-soluble mineral silicon fertilizer, the dissolving-out amount of silicon dioxide is significantly increased, so that the silicon dioxide can be quickly absorbed by crops, thereby increasing the yield of the crops.

Description

technical field [0001] The invention relates to a medical stone water-soluble mineral silicon fertilizer, which belongs to the technical field of chemical fertilizers. Background technique [0002] Most of the silicon fertilizers in the prior art are silicon fertilizers made from slag-type silicon fertilizers, also called citric acid soluble silicon fertilizers. The silicon dioxide in this silicon fertilizer is immovable in the soil, and the crops absorb it slowly. The effect mainly depends on whether the crops can effectively use the fertilizer applied to the soil. The so-called effective first means that the fertilizer applied to the soil must move to the root circle of the crop, or the root system of the crop can contact the fertilizer (mainly relying on nutrient ions) Diffusion and mass flow): Second, the nutrients absorbed by the crops from the soil can enter the root cells of the crops and be absorbed and utilized (nutrient uptake mechanism and kinetics). If these two...
