1, seed selection and soil preparation: select cold-resistant variety of lobular coriander, and apply sufficient base fertilizer after deep ploughing. 2. seed treatment: soak the seeds with carbendazim and then put them on a wet paper towel to accelerate germination. 3. Sowing in time: Sprinkle coriander seeds evenly on the border, cover the soil and spray water. 4. Post-management: control the ambient temperature between 18-22℃.

How to grow coriander quickly? 1, seed selection and soil preparation

The most suitable time for planting coriander is May-June. Choose cold-resistant lobular varieties with strong fragrance and good quality. Then the plot was deeply ploughed to a depth of about 25 cm, and organic fertilizer and decomposed chicken manure were added as base fertilizer during deep ploughing.

2, processing seeds

Before sowing, the coriander seeds should be soaked and germinated. The seeds should be soaked in carbendazim solution with the concentration of 1% for 20 minutes, then taken out and washed with clear water, let the seeds dry naturally, and then put on a wet paper towel to accelerate germination, and the temperature should be controlled at 25℃.

Step 3 sow in time

Coriander seeds can be sown after germination. Make a flat bed in the ground, sprinkle a layer of nutrient soil on the bed, then evenly sow the seeds on it, cover it with a thin layer of screened soil, spray water mist again, and build a small arch shed to keep warm and moisturize if necessary.

4, post-management

When coriander seedlings grow real leaves, they can be placed in the sun for about 5 hours every day, and the ambient temperature should be controlled between 18-22℃. When the temperature is high, the film should be uncovered and ventilated to avoid burning seedlings.
