Winter Scallion Cultivation Management Techniques

1. Watering in a timely manner: watering immediately after planting, the first water should not be too large to prevent the onions from ditching and foaming, every 5 to 6 days, and then watering the seedlings once again. In the future, water is poured once every 7 to 8 days, and the soil is often kept moist. After the heavy rain, the water in the ditch was promptly removed to prevent the accumulation of water and dead roots. Pour 1 water 10-15 days after "frost." When the "winter solstice" is poured, one more piece of frozen water is poured.

2, formula fertilizer: winter green onions generally top dressing 3 times. The first topdressing was performed when the seedlings were slowed down and began to grow vigorously. One-fifth of a hectare receives 8 kg of urea and 8 kg of ternary compound fertilizer. The second topdressing was carried out during the "cold dew" to "frost." The third top-dressing was carried out between "Lingdong" and "Xuexue". One-fifth of a hectare was topped with 20 kg of urea and 20 kg of potassium fertilizer. In addition to topdressing, foliar fertilizers are sprayed, and the spraying of ferrous sulfate, ammonium molybdate, copper sulfate, and manganese sulfate at a concentration of 1000 times can increase by more than 10%.

3, soil: Each time dressing, have poured a water, training a soil, soil is not appropriate to bury the heart of the leaves, not more than the "fork stock" is appropriate, not low. Soil should be cultivated when the soil moisture content is moderate and there is no mud, and care should be taken to avoid dew in the morning. When earth is soiled, be careful not to harm the onion leaves and cause diseases.
