Jinbao Seaweed Fertilizer (Chinese Herbal Medicine Foliar Fertilizer)
Foliar fertilization with Chinese herbal medicines is a technique where the fertilizer is dissolved in water and sprayed directly onto the plant leaves. This method is simple, cost-effective, and fast-acting, making it an excellent choice to improve both the yield and quality of medicinal plants. However, since these plants are used for human health, the selection of fertilizer must be done carefully. Organic and bio-fertilizers are highly recommended for their safety and long-term benefits.
One of the best options is algae-based bacterial fertilizer. Seaweed fertilizer is considered one of the most advanced types of fertilizers globally, offering significant advantages over chemical fertilizers in terms of stress resistance, natural activity, non-toxicity, and environmental safety. Jinbao's seaweed biological fertilizer is formulated with a high concentration of effective microbial strains. It uses microbial decomposition to activate the soil, enhance nitrogen fixation, and release phosphorus and potassium. Imported from Australia, it is developed using cutting-edge microbiology technology and methods. Extracted and purified from marine organisms, this pure, nutritious, and non-harmful liquid microbial fertilizer is ideal for growing high-quality Chinese medicinal materials.
Different types of Chinese herbs require specific foliar fertilizers. For root and rhizome plants like Salvia miltiorrhiza, Atractylodes macrocephala, Fuzi, and Pinellia, foliar application of phosphorus and potassium fertilizers is recommended. You can spray a 0.4% solution of potassium dihydrogen phosphate or a 2% superphosphate leaching solution mixed with 4% turfgrass leaching solution. The best time for spraying is during the late growth stage.
For fruit-bearing plants such as burdock and barley, foliar sprays should include nitrogen, phosphorus, and potassium or a compound fertilizer. A mixture of 1% urea, 2% superphosphate leaching solution, and 1% potassium sulfate works well, or you can spray a 0.2% to 0.3% solution of potassium dihydrogen phosphate. It's usually applied once or twice during the later growth period.
For whole-plant and flowering herbs like mint, chrysanthemum, safflower, and saffron, a 1% to 2% urea solution is commonly used. The amount per mu is around 50 to 60 kg, and it can be sprayed 1 to 3 times throughout the growing season.
When applying foliar fertilizers, there are several important considerations. First, choose the right time—spraying is best done on a sunny morning, not on rainy days. If rain occurs within three hours after spraying, wait until the next sunny day and reduce the concentration slightly. Second, ensure the fertilizer concentration is appropriate; too strong a solution can damage the plants and increase costs. Pay extra attention when using trace elements. Third, apply the fertilizer properly. For example, when using superphosphate, always use the clear supernatant after soaking for 24 hours.
