Detailed Explanation of the Key Technical Points of Field Management for Cilantro Cultivation
Cilantro, also known as coriander, is a common seasoning vegetable in our daily lives. It is rich in nutrients and loved by people for its pungent taste. When cultivating it, field management is extremely important in order to achieve high yields and improve the quality of cilantro. So how should field management be carried out when growing cilantro? Let's take a look together.
1. Seedling Stage Management
Cilantro seedlings emerge about 10 days after sowing. If heavy rain occurs during emergence, the field soil will become compacted after the weather clears, which affects the emergence of cilantro seedlings. Therefore, at this time, water once promptly to maintain soil permeability so that the seedlings emerge smoothly. When cilantro grows to 4-5 cm, thin the seedlings promptly so that the seedlings have enough space to grow. When thinning, remove poor-quality seedlings and keep strong seedlings of uniform size, which helps achieve uniform emergence.
2. Intertillage and Weeding
In addition to thinning seedlings, there is another extremely important task in seedling stage management, namely intertillage and weeding. Weeds lead to poor field permeability, compete with seedlings for nutrients, and affect seedling growth. Moreover, weeds are also hosts for pests, and when there are too many weeds, plants are prone to pests and diseases. Therefore, as soon as weeds appear in the field, they should be removed promptly. Manual pulling is recommended. If the soil in the planting plot is too clayey, or if watering is improper, it can easily cause soil compaction, which is bad for the growth and development of the cilantro root system, so intertillage should be carried out promptly. When seedlings are present, intertillage should not be too deep to avoid damaging the root system.
3. Fertilizer and Water Management
The growth period of cilantro is relatively short. Generally, it can be harvested in as fast as 40 days, or as slow as two months, so fertilization must be done early. During the seedling stage, do not water too much; watering once every 3-4 days is sufficient. However, during the peak growth period, fertilizer and water management should be strengthened. Water frequently to keep the soil moist. Fertilization should mainly use quick-acting fertilizers, applied together with watering, and can be poured or sprinkled. In the early stage, apply diluted human manure and urine at 1000 kg per mu or urea at 4 kg per mu by drenching 1-2 times. In the later stage, apply compound fertilizer at 50-10 kg per mu once a week by drenching. In addition, after harvest, apply a thin fertilizer once promptly, and spray gibberellin once before harvest, which can significantly increase yield.
4. Pest and Disease Control
The main pests and diseases of cilantro are mainly leaf spot disease and aphids. They affect yield and quality and affect farmers' income. Their control is mainly based on the principles of agricultural control, physical control, and biological control, with chemical control as a supplement. In the early stage of leaf spot disease, chlorothalonil and carbendazim solutions can be sprayed for control, and when aphids break out, abamectin and imidacloprid can be sprayed for control.
