The time for planting parsley is from late March to early April. When the seedlings grow 5-6 true leaves, they are selected for continuous sunny weather. Row spacing is 20 cm, plant spacing is 15 cm, planting 18,000 plants per acre, planting water immediately after planting. Three days after planting, the temperature in the shed during the day was maintained at about 23°C, and the temperature at night was not lower than 15°C, which was favorable for promoting rapid seedling growth. One week later, parsley will grow new roots and end the seedling period. In the early stage of growth, the outside temperature is relatively low, and it is necessary to diligently cultivate the soil to increase the temperature of the ground and promote the growth of roots, stems and leaves. When the plant height is about 20 cm, it enters a vigorous growth period and it is necessary to ensure adequate supply of fertilizer and water. Generally, 20 kg of urea is applied per acre with water, and fertilizer is continuously applied twice. In the late stage of growth, combining the application of protective fungicides to increase foliar micro-fertilizer can improve the quality and yield of parsley and increase the yield.
