In winter, roots are applied 2 to 3 times with 0.1% zinc sulfate, 600 times plant virus vaccine, 1500 times Shennongsu chelate fertilizer mixture, every 15 to 20 days, once, 5 to 6 kilograms per plant, inhibiting plant body The virus activity can reduce the occurrence and harm of spring. Leaf spot damages the leaves, causing the leaves to die, the winter pathogenic bacteria overwintering on the leaves, and the harm occurring when the spring is warm and humid.
