How to grow and manage parsley (coriander)? Please give a detailed introduction to coriander (coriander) cultivation and management can refer to the following methods: first, variety selection. Choose varieties with strong stress resistance and strong flavor, such as Tianjin coriander, Shandong big leaf coriander, Laiyang coriander and Beijing coriander and so on. Second, soil preparation and fertilization. The sandy loam with cool, loose, fertile and rich organic matter was selected and dried after deep ploughing. 1500-2000 kg of mature organic fertilizer, 10 kg of superphosphate and 5 kg of compound fertilizer were applied per mu. Third, soaking seeds to accelerate budding. Coriander seed coat is hard and should be rubbed open before sowing to facilitate sprouting. The seeds were soaked in low temperature to accelerate germination in summer. After soaking for 24 hours, the seeds were wrapped in a wet cloth and placed in an environment of about 20 ℃. The seeds could be sowed when they were exposed to white for 3-4 days. Fourth, sowing and shading net covering. It is better to sow coriander in summer and autumn with a seed amount of 1.5-2 kg per mu, covering a layer of fine soil with a thickness of 1 cm after sowing, and then covering the border with a sunshade net with a shading rate of 45%. Sprinkle enough water with flowers after sowing. After emergence, raise the sunshade net to 80-100 cm and form a small flat shed to cover the border until the end of harvest. Fifth, fertilizer and water management. The coriander should not be watered too much at the seedling stage, and should be watered once every 3-4 days. In the peak growth period, the management of water and fertilizer must be strengthened, the soil surface should be moist, and the fertilization should be mainly quick-acting fertilizer, combined with watering, 1000 kg of manure or 4 kg of urea should be applied 1-2 times per mu in the early stage, and 5-10 kg of compound fertilizer should be applied every 5-7 days in the later stage. Sixth, harvest. The seedlings can be harvested when the seedlings are unearthed for 30-50 days and the seedling height is about 15-20 cm. The yield can be increased by spraying gibberellin of 20ppm 7-10 days before harvest. Click to get more coriander planting techniques click to get more vegetable planting techniques
