1. time: timely sowing is the basis for realizing full seedling, strong seedling and high yield of broad bean. Early sowing with high temperature leads to rapid growth, weak cold resistance, easy to be damaged by freezing, and easy to be damaged by low temperature during flowering and pod setting; Sowing is too late, because the emergence time at low temperature is long and uneven, the plant growth is poor, the branches are few, the maturity is late, and the yield is low in the later stage. According to the climate characteristics of our region, fields sown in June 10 can generally avoid heavy frost during flowering and pod setting, so they fall off lightly.

Methods: In areas with fertile soil and high fertilization level, select fertilizer-tolerant and lodging-resistant varieties to give full play to the potential of increasing yield; In areas with poor soil and low fertilization level, select stable varieties with wide adaptability and barren tolerance. Before planting, every 667? Seed dressing with ammonium molybdate10g and Wisdom Fofo Agbo zinc 50g. First, dissolve ammonium molybdate with warm water, mix it with seeds evenly, then mix it with anthrax Fu Mei evenly, and then mix and sow.
