There are many methods for applying trace element fertilizers, such as soil fertilization, seed treatment and top dressing.
1. Soil fertilization. That is, when the base fertilizer, the seed fertilizer or the top dressing is applied, the trace element fertilizer is applied to the soil. Although this method of applying fertilizer has a low utilization rate, it has a certain aftereffect. Industrial waste containing trace elements and slow-acting micro-fertilizers often use this method of fertilization.
2. Seed treatment. Including soaking and seed dressing. When soaking seeds, the seeds are immersed in a trace element solution, the seeds absorb the solution and expand, and the fertilizer enters with water. The usual concentration is 0.01% to 0.1%, and the time is 12 to 24 hours. Seed dressing is to dissolve the trace element fertilizer with a small amount of water, spray the solution on the seed, stir evenly, so that the outside of the seed is stained with the solution and then dry and sowed, generally 2 to 6 grams of fertilizer per kilogram of seed.
3. Root dressing. That is, the trace element fertilizer solution is sprayed onto the plant by a sprayer, and is moved into the plant body through the leaf surface or the pores. A commonly used solution concentration is from 0.01% to 0.1%.
