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 applied to the soil, it needs to be further decomposed before it can be absorbed and utilized by plants. The effect of conditioning soil to supply nutrients is slow, and the absorption and utilization rate of plants is low. A large amount of organic matter, humic acid, amino acid and other active substances have a single effect

Embodiment 1

[0040] A. Raw material preparation:

[0041] According to the mass ratio, it includes 50% of nano-scale dolomite powder, 10% of xylitol, 10% of potassium silicate, 15% of biochar, and 15% of biochemical potassium fulvic acid;

[0042] B. Preparation of nanoscale dolomite powder:

[0043] ① Process the dolomite into a powder with a particle size of ≤0.5mm using a crusher, pulverizer, or grinder;

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

[0045] ③Transfer the dolomite powder heated in step ② into a cooling tower with a height of 20 meters. The upper layer of the cooling tower is equipped with a water mist cooling device (cooling water temperature ≤ 20°C) in the upper 20 to 10 meter section. The low-temperature water mist instantly bursts into finer powder and settles to cool;

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

[0047] C, sugar ...

Embodiment 2

[0058] The difference from Example 1 is that the preparation of raw materials in step A includes, by mass ratio, 60% of nanoscale dolomite powder, 12% of xylitol, 10% of potassium silicate, 9% of biochar, and 9% of biochemical potassium fulvate. %.

Embodiment 3

[0060] The difference from Example 1 is that the preparation of raw materials in step A includes, by mass ratio, 70% of nanoscale dolomite powder, 12% of xylitol, 10% of potassium silicate, 4% of biochar, and 4% of biochemical potassium fulvate. %.

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

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...
