Korean Coriander Cultivation Technology

Korea's big tree is also known as long-stemmed salamander, which is famous for its large tree, high yield and strong fragrance. The leaves and tender stems of this variety can be used for cold dressing, stir-fry, pickling or seasoning when used as soup. The yield per mu is 6000-8000 kg, and the economic income is 4-6 times that of conventional coriander varieties. The plant is semi-erect, with strong growth potential, plant height of 40-50 cm, odd-pinnate single leaves, 4-6 pairs of lobes, oval, leaf margin teeth, about 30 leaves per plant, strong adaptability, strong winter , Pumping late, good quality.

First, open field live. The planting period of Korean coriander is from September to October. After deep ploughing and drying the soil, the hoe was 1.5 meters wide, the ditch was 40 cm wide and 20-30 cm high. Spread 1500 kg of rotten pig manure and 50 kg of compound fertilizer as basal fertilizer per mu. After digging into the ground, level the noodles. Seed 2-3 kg per acre. After sowing, rake loose the topsoil, or ditch the floating ditch to cover it, and then sprinkle water and cover the grass to bring it into close contact with the soil to facilitate germination. In dryland sowing, the cover grass is generally moisturized, and the cover grass is properly removed after the seeds are unearthed.

Second, moisture management. Coriander is resistant to drought and wet. Keep the garden soil moist frequently to promote fast plant growth, fresh leaves and high yields. Watering once a day after sowing promotes rapid seed germination. After the sprouts are unearthed, the cover grass is removed in time, and watering is often carried out, but it should not be flooded with large water to prevent the plants from getting mud, affecting growth and reducing quality. During the prosperous period of production, the water demand is large.

Third, fertilize. In the early stage of growth, the amount of growth is small, not much fertilizer is required, and there is a base fertilizer for growth. Generally, in combination with watering, top-up nitrogen fertilizer is applied once a week, and the concentration should be low to avoid scorching leaves. Method: Add 100-150 grams of urea per 50 kilograms of water, or sprinkle 5 kilograms of urea per acre, and then immediately and uniformly splash water to quickly dissolve the urea into the soil. In the vigorous growing season, the amount of fertilizer required increases rapidly. In addition to the available nitrogen fertilizer, phosphorus and potassium fertilizers should be added, and the concentration should be appropriately increased. Apply 15 kg of urea, 20 kg of superphosphate, and 10 kg of potassium chloride per acre, and apply it once a week in 3 times. After fertilizing, wash the leaves with water.

Fourth, between seedlings. When the seedlings are about 15 cm in height, one seedling can be left at an interval of 3-5 cm, or one cluster of seedlings can be left at about 20 cm, with 3-5 seedlings per cluster.

5. Harvesting. Coriander is not strictly harvested. When the plant height is about 40 cm and it has 18-20 leaves, it can be harvested in batches as needed.
