Problems solved by technology

The demand of crops for calcium and magnesium is also most obvious during the fruit expansion period. Conventional calcium and magnesium fertilizers are easy to be lost when applied early, and they are not absorbed when applied late, which will cause waste and even pollution.

Embodiment 1

[0030] An oily suspended magnesium and calcium fertilizer, comprising the following components: 112g of water, 40g of magnesium hydroxide ore powder (the content of magnesium hydroxide is 87%), 3g of light calcium carbonate (the content of calcium carbonate is 99%), wetting agent MSR-TT1 4g, dispersant MSD-511 8g, xanthan gum 0.4g, aluminum magnesium silicate 4.0g, vegetable oil 20g, propylene glycol 8.0g, adjust the pH between 8.0-9.0 with potassium hydroxide.

[0031] Prepare above-mentioned oily suspension magnesium, calcium fertilizer adopt such as figure 1 Described device, specific method comprises the steps:

[0032] 1) Add a specified amount of water (factory tap water) into the high-speed shearing machine 1, start the high-speed shearing machine 1, adjust the speed to 200r / min, and add the weighed magnesium hydroxide ore powder and light calcium carbonate ore powder in turn , Wetting agent MSR-TT1, dispersant MSD-511, thickener xanthan gum and aluminum magnesium sili...

Embodiment 2

[0039] The difference with embodiment 1 is:

[0040] An oily suspended magnesium, calcium fertilizer comprises the following components: water 147g, magnesium hydroxide ore powder 30g (magnesium hydroxide content is 87%), light calcium carbonate (calcium carbonate content is 99%) 1.6g, wetting Agent MSR-TT1 2g, dispersant MSD-511 4g, xanthan gum 0.2g, magnesium aluminum silicate 1.0g, vegetable oil 10g, propylene glycol 4.0g, adjust the pH between 8.0-9.0 with potassium hydroxide.

Embodiment 3

[0042] The difference with embodiment 1 is:

[0043] An oily suspended magnesium, calcium fertilizer comprises the following components: 128g of water, 34g of magnesium hydroxide ore powder (magnesium hydroxide content is 87%), light calcium carbonate (calcium carbonate content is 99%) 2.4g, wetting Agent MSR-TT1 3g, dispersant MSD-511 6g, xanthan gum 0.3g, magnesium aluminum silicate 4.0g, vegetable oil 16.0g, propylene glycol 6.0g, adjust the pH between 8.0-9.0 with potassium hydroxide.

[0044] The oily suspension magnesium and calcium fertilizers obtained in Examples 1, 2, and 3 are detected, and the results are shown in the table below. It can be seen that the products prepared in the three examples are all in a homogeneous suspension state, and have good automatic dispersion. Rates are all above 95%, and Examples 1 and 3 have reached more than 99%, and the particle size has reached nanoscale.

Abstract

The invention relates to the technical field of fertilizer. The invention particularly provides oily suspended magnesium and calcium fertilizer and a preparation method and device thereof. The oily suspended magnesium and calcium fertilizer comprises 15-20% of magnesium hydroxide mineral powder, 0.8-1.5% of light calcium carbonate mineral powder, 1.0-2.0% of a wetting agent, 2.0-4.0% of a dispersing agent, 1.1-2.2% of a thickening agent, 5-10% of vegetable oil, 2.0-4.0% of an antifreezing agent and the balance of water, and the pH value of the fertilizer is adjusted to 8.0-9.0 by potassium hydroxide. Through shearing, magnesium hydroxide mineral powder and light calcium carbonate mineral powder are cut to nanoscale, and through affinity of Mg<2+> and Ca<2+> to the dispersing agent and thevegetable oil, a stable suspension state is kept, a dripper and a filter can be prevented from being blocked, the pH value of acidified soil is increased, the buffering capacity of the soil is enhanced, calcium and magnesium nutrients can be continuously provided for crops, and the growth requirements of the crops are met to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of fertilizers, and in particular provides an oily suspended magnesium and calcium fertilizer, a preparation method and a device, and is an oily suspended magnesium fertilizer that can be used to adjust the pH value of soil. Background technique [0002] In the context of the current development of agricultural modernization and green agriculture, increasing crop yield, improving crop quality, scientific fertilization, increasing fertilizer utilization rate, reducing the amount of fertilizer applied, balanced nutrient fertilization, and continuously improving soil are the goals of fertilizer research and development. The main fertilizers in my country are chemical fertilizers composed of N, P, and K. Due to long-term unreasonable use of chemical fertilizers, the current nutrient level and physical level of the soil seriously limit the development of agriculture. After research and investigation by many scien...
