How do you grow cilantro in a greenhouse? Here is an introduction
You can refer to the following methods for growing cilantro in a greenhouse:
1. Sowing. Cilantro is generally sown from late October to early December. After sowing and before emergence, use 250 to 300 grams of 25% nitrofen wettable powder, or 100 to 200 grams of 50% prometryn wettable powder per mu, mix with 75 to 90 kg of water, stir evenly, and spray on the bed surface, which can achieve a good weed control effect.
2. Management. Cilantro emerges about 8 days after sowing. During emergence, the temperature should be higher, keeping 20°C to 25°C during the day and 10°C to 15°C at night. After emergence, keep 17°C to 20°C during the day and 10°C at night. When the daytime temperature exceeds 25°C, ventilate, and stop when it drops to 20°C. When the seedlings are 4 to 5 cm tall, thin them, keeping a plant spacing of 2 to 3 cm. Cilantro is generally not watered during the seedling stage. When the seedlings are about 10 cm tall, they enter the vigorous growth period. You can choose a sunny morning to water and fertilize, applying 10 to 15 kg of ammonium sulfate or 5 to 10 kg of ammonium nitrate per mu. During the growth period, topdressing is needed 1 time and watering 2 to 3 times. Cilantro grows quickly, and it can be harvested 30 to 50 days after sowing, when the plants are about 20 cm tall.
3. Pest and disease control. The main pests of cilantro are aphids and cutworms. To control aphids, use a 2000 to 3000 times solution of 50% pirimicarb or 50% biajiewu wettable powder, spraying once every 6 to 7 days, for 2 to 3 consecutive treatments.
