Embodiment Construction

[0018] Take 10kg of weathered coal (crushed particle size above 60 mesh, humic acid content greater than 50%), 1.2kg of KOH, 7.0kg of urea, 0.4kg of potassium sulfite, and 60kg of water into the stirring tank, and the temperature is controlled at 100°C ± 50°C. React for 3 hours, then centrifuge (or through natural precipitation for more than 20 hours), and transfer the supernatant to the chelation stirring tank. Then put in 10kg of diammonium phosphate, 15kg of potassium chloride, 0.4kg of zinc sulfate, 0.5kg of manganese sulfate, 0.6kg of boric acid, and 0.05kg of ammonium molybdate, and stir fully at room temperature (20°C) to dissolve completely.

[0019] Test PH6.76, because the pH value is suitable, there is no need to adjust the pH value.

[0020] After the greenhouse vegetables (eggplant, cucumber, grape, etc.) were applied, the results showed that compared with the isonutrient fertilizer control area. Cucumber production increased by 15-25%, eggplant production increa...

Abstract

The invention relates to a humic acid liquid fertilizer and a preparation method thereof, belonging to the technical field of fertilizers. The fertilizer comprises the following effective components in percentage by weight: 4-16% of humic acid, 5-14% of effective nitrogen, 4-9% of phosphorus pentoxide, 4-11% of potassium oxide, 0.02-0.35% of trace element zinc, 0.04-0.70% of manganese, 0-0.6% of copper, 0-0.7% of iron (ferrous iron), 0.02-0.2% of molybdenum, 0.02-0.35% of boron and 0.01-0.5% of chitosan. The preparation method comprises the following two process steps: the preparation of a humic acid activating clear liquid, and the addition and chelation of various nutrient elements. The liquid fertilizer is a non-precipitating and non-flocculent clear liquid, and is especially applicable to trickle irrigation and spraying devices.

Description

Technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a humic acid liquid fertilizer and a preparation method thereof. Background technique [0002] With the sustainable development of agriculture, the production scale of liquid fertilizer will continue to develop and expand. Liquid fertilizer production in the United States accounts for as much as 30% of total fertilizer production. In our country, the production and application of pollution-free liquid fertilizers are also emerging and expanding. Compared with solid fertilizers, liquid fertilizers have the advantages of fast fertilizer efficiency, balanced nutrition, and convenient application. [0003] Chemical fertilizers (including liquid and solid fertilizers) play a significant role in increasing crop yields. However, it also brings harm to the soil such as compaction, salinization, and pollution; the long-term use of chemical fertilizers will seriously reduce or even ...
