According to tests, the application of manganese fertilizer can not only increase wheat production by about 10%, but also increase the protein content of wheat grain and improve the quality of wheat, especially for calcareous soil, saline-alkali land, sandy land and low organic matter content. The use of manganese fertilizer has more pronounced results. Manganese fertilizer is commonly used manganese sulfate, manganese content is generally 26% -28%, application methods are the following: Seed treatment Seed treatment usually soaked or seed dressing. Soaking can use 0.1% sulfuric acid solution, every kilogram of wheat seed soaked with 1 kg of fertilizer solution for 12-24 hours. For seed dressing, use 4-8 grams of manganese sulfate per kilogram of wheat seed. Dissolve with a small amount of water and mix well with the seeds. The base fertilizer is mixed with 1 kg of manganese sulfate per acre, and is mixed with soil fertilizer, urea, superphosphate and other fertilizers to reduce the fixation of manganese fertilizer and improve fertilizer efficiency. Outside the root dressing fertilizer in wheat seedling stage or jointing and booting stage spraying 0.05% ~.1% manganese sulfate solution 30 ~ 50 kg, spray 7 to 10 days intervals, a total of 2 or 3 times. Precautions: When applying fertilizers outside the roots, do not blindly increase the dosage so as not to damage the leaves. When using manganese fertilizers, it must be used in conjunction with NPK fertilizers in order to give full play to its role in increasing production.
