Problems solved by technology

On the one hand, the calcination temperature of 800-1200°C is too high, and the calcination time of 0.5-2h is too long, which leads to excessive decomposition of nutrients in dolomite, resulting in loss and waste of resources; on the other hand, the nutrients in dolomite are still in mineral state after calcination. After being

Example Embodiment

[0039] Example 1

[0040] A. Preparation of raw materials:

[0041] In terms of mass ratio, it includes 50% nano-level dolomite powder, nano-level dolomite powder 50%, xylitol 10%, potassium silicate 10%, biochar 15%, and biochemical potassium fulvic acid 15%;

[0042] B. Preparation of nanometer dolomite powder:

[0043] ① Use crushers, pulverizers and grinders to process dolomite into powder with a particle size of ≤0.5mm;

[0044] ②Put the dolomite powder prepared in step ① into a rotary calcining kiln at 760°C and heat it for 15 minutes;

[0045] ③Transfer the dolomite powder heated in step ② to a 20-meter-high cooling tower. The upper layer of the cooling tower is equipped with a water mist cooling device (cooling water temperature ≤20℃). The high-temperature dolomite powder encounters The low-temperature water mist instantly burst into finer powder and settled to cool;

[0046] ④Put the cooled dolomite powder into a nano jet mill, and pulverize to a particle size ≤50nm;

[0047] C. ...

Example Embodiment

[0057] Example 2

[0058] The difference from Example 1 is the preparation of raw materials in step A. In terms of mass ratio, it includes 60% dolomite powder, 12% xylitol, 10% potassium silicate, 9% biochar, and potassium fulvic acid 9 %.

Example Embodiment

[0059] Example 3

[0060] The difference from Example 1 is the preparation of raw materials in step A. In terms of mass ratio, it includes nanometer dolomite powder 70%, xylitol 12%, potassium silicate 10%, biochar 4%, and biochemical potassium fulvic acid 4 %.

[0061] In the vegetable base of Bendatang Village, Jinjiang Town, Chengmai County, Hainan Province, the product effect verification test of the present invention was carried out. The experiment set up treatment A without applying fertilizer, treatment B with 100kg / mu of conventional compound fertilizer (N15-P15-K15+TE), treatment C with 100kg / mu of the product of Example 1, treatment D of 100kg / mu of the product of Example 2, Apply 100kg / mu of the product of Example 3 for treatment E (each fertilizer is buried in the soil 5-10cm). Three replicates were set up for each treatment, and each replicate covered an area of ​​25 square meters, and planted sweet peppers (variety: Oriental Pearl 106F, planting period 90 days). By ...

Abstract

The invention relates to a functional fertilizer for regulating a micro-ecological environment of soil. 50-80% of nanometer dolomite dust, 5%-15% of sugar alcohol, 5%-15% of potassium metasilicate, 5-10% of charcoal and 5%-10% of biochemical potassium fulvic acid are utilized to prepare the functional fertilizer according to the following steps: A) preparing raw materials; B) preparing nanometer dolomite dust; C) preparing a sugar alcohol water solution; D) chelating nutrients; E) pelleting for the first time; F) pelleting for the second time; G) drying. The functional fertilizer can be used for improving soil hardening, regulating soil PH and regulating soil acidification; the functional fertilizer can be used for supplementing organic matters and various medium trace elements for the soil, regulating the saturability of soil base, cation exchange capacity and nutrient balance, reducing aluminum and manganese toxicity damage and improving soil salinization; the functional fertilizer can be used for absorbing passivated heavy metal and repairing soil heavy metal pollution; the functional fertilizer also is capable of creating an excellent living environment for soil beneficial microorganisms, boosting the growth and reproduction of the microorganisms and recovering the excellent micro-ecological environment of soil.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a functional fertilizer capable of regulating soil micro-ecological environment. [0002] technical background [0003] Soil is the foundation of agricultural planting, and a healthy soil environment is the foundation of agricultural development. In recent years, unscientific farming patterns, excessive planting, and a large number of irrational use of agrochemicals have widely existed in major agricultural areas in my country, resulting in widespread thinning of the farmland soil, a significant reduction in soil organic content, serious nutrient imbalances, and soil microbial communities. Attenuation, resulting in soil compaction, acidification, salinization, heavy metal pollution in cultivated land, poor ability to prevent drought and waterlogging, and the fertility of cultivated land continues to decline. [0004] The deterioration of soil environment has brought many negative effect...
