Coriander is a nickname of wolfberry, also known as scallop and scallop, and is a biennial herbaceous plant of the Umbelliferae family. It is mainly used as seedlings for vegetable consumption.
1. Variety selection coriander leaves and lobular varieties. Although the yield of leaflet varieties is not as high as that of large leaf varieties, it has a strong aroma, cold resistance and strong adaptability. Therefore, it is usually cultivated to select leaflet varieties.
2. Soil preparation fertilization choose land with fluffy soil, rich organic matter, and convenient irrigation and drainage. After the harvest of the former crop, turn the soil in time, depth 15-20 centimeters, let it be weathered and dried for more than 2 weeks, and then spread the quality farmhouse per acre. Fertilizer 4000-5000 kg, compound fertilizer 10-15 kg as basal fertilizer, cultivating after making the surface width 140-150 cm, height 20-25 cm, long and the length of the plot, the width of 30-40 cm, double sidewalk. The puppets plead with the earth to be finely chopped, fluffy, and flat. If the drill should be drilled, it should also be planted at a distance of 8-10 cm wide and 4-5 cm wide and about 2 cm deep at the surface to prepare for sowing.
3. Seeding can be planted from the beginning of late August to early April in the spring of next year. Seeds are planted before sowing. The seeds are then placed in 50-55°C hot water and mixed with hot seeds for 20 minutes until the water temperature drops to around 30 degrees. Seed soaking, sowing after 18-20 hours, or sowing after germination. Usually 2-3 kilograms of seeds are sown per acre.
4. Water and Fertilizer Management Coriander is hi moist and should always be watered to maintain moist and moist. It is also possible to timely irrigate (ditch irrigation) when the soil is slightly monotonous, but drain the water in the field ditch immediately after the soil is wet, so as not to affect plant growth.
5. The light temperature requires that the parsley is able to withstand low temperatures of -1 to -2 degrees. The optimum temperature for growth is 17-20 degrees, and growth is retarded at more than 20 degrees, and stagnant growth at temperatures above 30 degrees. Hi light, but also shade. If the shade in the autumn is about 50% shaded, and fog is often sprayed on the leaves, the horizontal arching film or greenhouse insulation will be conducted in winter and early spring to increase the yield and quality.
6. Coriander harvested can be harvested 6-9 weeks after sowing. Roots are picked up and harvested to remove dirt and yellowish leaves and other impurities. The bundles are washed and sold on the market. Usually 1000-2500 kilograms per mu, high yield up to more than 3,000 kilograms.
