Phosphorus deficiency in phosphorus-deficient maize showed poor root development and slow growth during seedling stage. The obvious phosphorus deficiency in the plants was concentrated in the 5-leaf stage, and the symptoms of purpleish leaves, purple leaves, and curled leaves were observed. Phosphorus deficiency can also cause the filament to be pulled out slowly, affecting pollination, and the ear is curled, the ear is not uniform, the grain is not full, the baldness phenomenon occurs, and the maturity period is delayed. Therefore, it should be ensured that 25 to 30 kg of calcium phosphate per acre is used together with nitrogen fertilizer as base fertilizer. When zinc deficiency and zinc deficiency occur, the lower part of the new leaves of maize seedling stage and growth period is light yellow or even white. After the leaf grows, yellowish spots or green streaks appear between the veins, and even the symptoms of mosaic leaves can be seen. Severe zinc deficiency, 2.5 to 3 kg of zinc phosphate per mu in the seedbed. The live corn should be applied with 1 to 1.5 kg of zinc sulfate as the base fertilizer. It can also be remedied by foliar fertilization method, sprayed with 0.1% to 0.2% zinc sulphate solution for 2 to 3 times, sprayed once every 7 to 10 days, and each spray solution is about 50 kg. The boron deficiency symptoms of boron-deficient maize are that the young leaves are weakly stretched, and the inter-pulmonary tissue of the upper leaves is thin and white-transparent. The plants grow thin and thin, the ears are deformed, the grains are not arranged neatly, shrinking, and the top grains are empty. The remedy is to spray 0.2% boric acid or borax 2 to 3 times on the foliar surface, each time about 10 days, each time spraying 50-75 kg.
