                Product features:
                 
                1. Strong acidity and high fertilizer efficiency
                 
                It can reduce the pH of soil and water, activate calcium and magnesium ions, promote the co absorption of calcium, magnesium, phosphorus and nitrogen by crops, balance nutrition and improve fertilizer utilization.
                 
                2. Scale removal, no precipitation:
                 
                In alkaline soil or alkaline irrigation water area, jiangjianling can be used together with other fertilizers to effectively reduce the content of water-insoluble matter in fertilizer, remove calcium and magnesium scale in pipeline, prevent pipeline blockage, and is easy to use.
                 
                3. All water soluble, fast dissolving
                 
                Jiangjianling is completely water-soluble, with fast dissolution rate and no residue. It also helps to increase the dissolution rate of potassium sulfate and other raw materials.
                 
                4. High content, easy to match:
                 
                Jiangjianling is rich in nitrogen, phosphorus and other nutrients, the total nutrient is more than 60%; The method is simple and widely used, and can be used for drip irrigation alone; It can also be used as a "companion" of water-soluble fertilizer, and can be used together with ordinary water-soluble fertilizer; It can also be used as raw material of water-soluble fertilizer or compound fertilizer.
                 
                The dominant mechanism of jiangjianling acid fertilizer is as follows
                 
                1. Strong acidity and high fertilizer efficiency: the pH value of jiangjianling is 3 ± 1, medium strong acid; Phosphorus in traditional phosphorus is easy to be fixed by calcium and magnesium in alkaline soil, and its migration ability is reduced. Phosphorus can only move in a small range near the fertilization area, resulting in the decline of phosphorus absorption and utilization.
                 
                The following figure shows the permeability of Monoammonium, diammonium and Prochloraz in 4cm soil. It can be clearly seen from the figure that jiangjianling has higher penetration rate, so jiangjianling as a phosphorus source has higher migration ability and higher nutritional efficiency.
                 
                2. Scale removal and no precipitation: the acidic properties of jiangjianling can increase the solubility of calcium phosphate and magnesium phosphate in water, reduce the precipitation of calcium and magnesium, make the fertilizer solution clearer, and reduce the precipitation and scaling; It can remove high concentration bicarbonate ion and reduce EC Value of drip irrigation. Prevent bicarbonate ion, calcium ion, magnesium ion and other insoluble substances from blocking the drip irrigation system. For the northwest, North China and other hard water areas, it has the advantages of prolonging the service time of equipment, uniform and efficient distribution of water and fertilizer, and reducing the workload.
                 
                3. Improve alkaline soil and water, activate trace elements: the most suitable soil pH value for most crops is 5.5-6.5, weak acid. When the pH value of alkaline soil is more than 7.5, the application of jiangjianling as fertilizer or saline alkali soil amendment can effectively reduce the pH value of soil micro area, change the soil acid-base balance, thus improving the soil physical and chemical properties, improving soil structure, promoting crop growth and other functions. In addition, it can improve the sanitary conditions of fertilized soil, improve the community structure and biological activity of ammonifying bacteria, nitrifying bacteria, decomposing bacteria and nitrogen fixing bacteria in soil.
                 
                Effect of jiangjianling water soluble fertilizer on pH of alkaline irrigation water (fertilizer water ratio 1kg: 250kg)
                 
                Application method:
                 
                1. It can be applied by drip irrigation alone or in combination with other water-soluble fertilizers;
                 
                2. The recommended dosage is 2kg / mu each time (the specific dosage depends on the water quality). When the product is used in the water with high calcium and magnesium content and pH > 8.0, the dilution ratio should be more than 250 times. In the area with low calcium and magnesium content and pH < 8.0, the dilution ratio should be more than 1000 times.
                 
                matters needing attention:
                 
                1. This product can not be mixed with strong alkaline pesticide.
                 
                2. Due to the complexity of crop nutrient deficiency and fertility tolerance, as well as the soil structure and fertility
                 
                Different, the specific amount of use to follow the advice of local agricultural technical personnel.
                 
                3. This product has strong acidity and certain irritation. Avoid contact with eyes and wounds.
