Iron-deficient wheat in the early stage of growth or when the plant is found to be deficient in iron, sprayed with 0.2% to 0.3% ferrous sulfate solution.
Boron deficiency fertilizer as base fertilizer: 1 kg of borax per acre, applied to the soil before sowing. For seed fertilizer: use 10 grams of borax, dissolve in 5 kg of water, mix 50 kg of wheat. Top dressing: In the wheat seedling stage, jointing stage and booting stage, spray each time with 0.1% to 0.2% borax solution.
Manganese deficiency fertilizer as base fertilizer: 1 kg of manganese sulfate per acre, combined with soil preparation into the soil. Seed fertilizer: When planting, mix 4-6 grams of manganese sulfate per kilogram of wheat. Top dressing: Foliar application of 0.1% to 0.2% manganese sulfate solution in the wheat seedling stage, jointing stage, flowering stage or when the plant is deficient in manganese.
Copper deficiency fertilizer as base fertilizer: 1 to 1.5 kg of copper sulfate per acre, applied to the soil during soil preparation. Seed fertilization: When planting, mix with 0.2% to 0.3% of the amount of copper sulfate, mix well and pile up for 12 to 17 hours. Top dressing: In the growing season, wheat is found to be deficient in copper, and it is sprayed with 0.2% to 0.4% copper sulfate solution in time.
Zinc deficiency fertilizer as base fertilizer: 1 to 2 kg of zinc sulfate per acre, applied to the soil during soil preparation. Soaking seeds: Put the selected wheat seeds into a 0.05% zinc sulphate solution, soak for 12 to 24 hours, remove them, and dry them for sowing. For top dressing: In the wheat seedling stage, 1 kg of zinc sulphate per acre, 15 to 20 kg of fine dry soil or organic fertilizer, and ditching between rows, the earlier the effect is better. Top dressing: For wheat seedling, jointing and heading, foliar application with 0.1% to 0.2% zinc sulphate solution.
