Embodiment 1
[0031] Na + - Soil or K + - Soil aggregates (20g) (Na + Belonging to weakly polarized ions, K + Belonging to strongly polarized ions) were weighed into a 500ml graduated container, and the corresponding electrolyte solution (NaNO 3 and KNO 3 ) to fill the graduated container. and 0.1mol / L. The decomposition process begins when the aggregates come into contact with the electrolyte solution. After two minutes, the cylinder was inverted four times to ensure that the particles (microaggregates and individual particles released after disintegration) were evenly distributed in the cylinder. The cylinder is then left to stand. The time required to collect a particle of a certain diameter is calculated according to Stokes' law at a set temperature and settling distance. Then, the supernatant containing d<10, 5 or 2 μm diameter particles was removed from the cylinder. The suspension is dried and the mass of the solid particles is measured. Mass percentage W (<d relative to th...

[0034] This implementation provides a kind of preparation method of the soil conditioner that improves alkaline soil pH, electrolyte composition and agglomeration, comprises the following steps:
[0035] According to the mass percentage, the following raw materials are included: 50% of humate, 15% of electrolyte, 15% of biochar, 15% of physiological acid fertilizer and 5% of water.
[0036] (1) weatherized coal is used as humate raw material (can adopt other raw materials in other embodiments) and K by mass ratio 1:3 + The concentration of 0.1mol / L is mixed with the extract solution, and the extract solution is KOH and K 4 P 2 o 7 The mixed solution, and constantly stirred to make the solution fully mixed, then left to stand for 24h, extract the upper layer of potassium humate suspension;
[0037] (2) repeat step (1) 2 times, obtain humate potassium suspension for subsequent use;
[0038] (3) Add an appropriate amount of calcium nitrate to the potassium humate suspension o...
