Common foliar fertilizer preparation method

In spring, many crops enter a rapid growth phase, making it an ideal time for foliar fertilization. Proper application of foliar fertilizers can significantly enhance crop development and yield. Below are several effective methods for preparing different types of foliar fertilizers. Urea solution is commonly used at a concentration of 0.5% to 1%, which means dissolving 0.5 to 1 kg of urea in 100 kg of water. However, urea with a biuret content exceeding 1.5% should not be used as a foliar fertilizer due to potential toxicity. Another option is the urine washing solution, which serves both as a nitrogen source and an insecticide. Mix 0.5 to 1 kg of urea with 100 kg of water, then add 70 to 100 g of washing powder. This mixture should be used immediately after preparation to maintain effectiveness. Biogas slurry is another valuable resource. It is rich in available nitrogen and can be quickly absorbed by leaves. To prepare, mix 10 kg of filtered biogas slurry with 100 kg of water and use it right away to prevent nitrogen loss through evaporation. Potassium dihydrogen phosphate is often applied at a concentration of 300 g per 100 kg of water. For potassium sulfate, a 1% to 1.5% solution is recommended, typically using 1 to 1.5 kg of potassium sulfate in 100 kg of water. Grass ash leaching liquid is useful for providing nutrients and improving soil structure. Take 5 to 7 kg of fresh grass ash, mix with 100 kg of water, let it sit for 14 hours, and then spray the clear liquid. Superphosphate leaching solution helps supplement phosphorus and control pests like cotton bollworms. Use 2 to 3 kg of calcium phosphate in 100 kg of water, stir well, let it stand for 24 hours, and then filter before use. For NPK mixed solutions, dissolve 100 kg of a 2% to 3% superphosphate leaching solution, then add 0.3 to 0.5 kg of urea and 1 to 1.5 kg of potassium sulfate. Ferrous sulfate solution is prepared by dissolving 200 to 300 g of ferrous sulfate in 100 kg of water. Since iron is poorly transported within leaves, multiple applications are necessary. Adding 50 to 70 g of washing powder per 100 kg of solution can improve absorption. Rare earth micro-fertilizer solutions can boost chlorophyll levels and enhance photosynthesis. A concentration of 0.08% to 0.1% is recommended—add 80 to 100 ml of rare earth fertilizer to 100 kg of water. Zinc sulfate solution is made by dissolving 100 to 200 g of zinc sulfate in 100 kg of water. Adding a small amount of lime water can improve its effectiveness when applied. Borax solution requires 200 to 300 g of borax in 100 kg of water. Since borax dissolves slowly in cold water, it's best to first dissolve it in 4 to 5 kg of warm water (around 45°C), then top up to 95 to 96 kg. Manganese sulfate solution is prepared by dissolving 50 to 100 g of manganese sulfate in 100 kg of water. Ammonium molybdate solution is made by dissolving 50 to 100 g of ammonium molybdate in 100 kg of water for foliar application. These foliar fertilizers are essential tools for maintaining healthy and productive crops during the growing season. Always follow proper mixing instructions and apply them at the right time for maximum benefit.

Mini Peristaltic Pump

Mini peristaltic pumps are small, compact devices that are used to pump fluids in a variety of applications. Mini peristaltic pumps are self-priming, which means that they can start pumping fluids without the need for manual priming.They work by using a series of rollers that compress a flexible tube, creating a vacuum that draws the fluid into the pump. The rollers or shoes then release, allowing the tube to expand and push the fluid out of the pump. Mini peristaltic pumps are classified based on their flow rate, which is measured in mL/min or L/min. They can range from very low flow rates of a few mL/min to high flow rates of several L/min. They can also be classified based on their tubing size, which can range from very small diameters of a few millimeters to larger diameters of several centimeters. Mini peristaltic pumps can be further classified based on their application, such as in medical devices, laboratory equipment, or industrial processes.Mini peristaltic pumps are versatile devices that can be used in a wide range of applications, making them a popular choice for many industries.
