Abstract

The invention discloses a special solid water-soluble fertilizer for coptis chinensis and a preparation method thereof. The special solid water-soluble fertilizer for coptis chinensis comprises the following raw materials by weight percentage: 50-65% of water-soluble ammonium polyphosphate, 10-15% of potassium nitrate, 10-15% of ammonium dihydrogen phosphate, 10-15% of dipotassium hydrogen phosphate and 3-10% of urea; the total nutrient content of the fertilizer reaches 76% or more, and the aggregated phosphorus accounts for 65% or more of the total phosphorus. The long-term sustained releaseof water-soluble ammonium polyphosphate is combined with the quick-acting effect of ordinary water-soluble fertilizers such as potassium dihydrogen phosphate, potassium nitrate, ammonium dihydrogen phosphate and urea to provide sufficient nutrients for each growth stage of coptis chinensis; the absorption and utilization rate of fertilizer nutrients is high, the loss of fertilizer nutrients is less, environmental pollution caused by conventional water-soluble fertilizers is lowered, the manual work is saved, the yield is increased, fertilization costs are reduced, and the planting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizers, in particular to a special solid water-soluble fertilizer for coptis chinensis and a preparation method thereof. Background technique [0002] Water-soluble fertilizer is a multi-component compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water and is more easily absorbed by crops. At present, the main raw materials for the production of water-soluble fertilizers in the industry are macroelement compounds containing nitrogen, phosphorus and potassium. (Phosphate, urea, nitrate, etc.), compounds containing calcium and magnesium elements, compounds containing copper, iron, manganese, and zinc trace elements (sulfate, hydrochloride, etc.), humic acid, amino acids, etc. Potassium macroelement compounds and trace element compounds are dissolved in water and dissociated into anions and cations to be absorbed by plants. [0003] Copt...
