Characteristics of parsley coriander Umbelliferae. It can tolerate low temperatures from -1°C to 2°C, with a suitable growth temperature of 17°C to 20°C, slow growth over 20°C, and stop growth at 30°C. Coriander does not require strict soil, but soil with good soil structure, strong fertilizer and water retention, and high organic matter content are conducive to the growth of coriander.
The varieties of parsley are cilantro varieties with large leaves and lobular varieties. Large leaf cultivars are tall, with large leaves, few and shallow nicks, light fragrance, and high yield; lobular cultivars have shorter plants, smaller leaves, deeper cuts, stronger aromas, cold tolerance, and stronger adaptability, but have lower yields and are generally cultivated.

In January, there is no ventilation and ventilation from January to February. When the seedlings turn green, cultivators, loose soil and weeds are used. When the seedling height was 10 cm, the plants entered a vigorous growth period, and the greenhouse was maintained at 15°C to 25°C. Each time about 15 kg of ammonium sulfate is used per acre, which can be harvested 1 to 2 times in advance.
