How to grow autumn coriander in Northeast China?

1. Site selection and land preparation

Choose soil that is rich in organic matter, loose and fertile, and has good drainage and irrigation conditions. After harvesting the previous crop, crop residues should be removed promptly and wood ash can be spread to sterilize and eliminate pests.

2. Apply enough basal fertilizer

Apply 2,000 kg of fully decomposed farmyard manure and 40 kg of triple compound fertilizer per mu, plow and harrow the soil deeply, and make ridges 1.0-1.5 meters wide and 20-25 centimeters high to facilitate watering and fertilizing in the later stage.

3. Seed treatment

The shell of coriander seeds is hard, so the seeds should be rubbed open before sowing to promote germination. The seeds can be soaked in warm water at 25-30℃ and then wrapped in moist gauze for germination to increase the germination rate.

4. Key points for sowing

When planting, you should water the field in advance to ensure soil moisture, spread the seeds evenly in the field, and then cover them with 1-2 cm thick fine sand. After sowing, cover the field with a layer of straw or stalks to retain moisture, and remove it after the seedlings emerge.

5. Water and fertilizer management

After the seedlings emerge, they should be irrigated frequently with small amounts of water. When they grow to a height of more than 5 cm, they can be irrigated with light fertilizer water. Fertilizers can be urea or special fertilizers for leafy vegetables to promote their rapid growth and increase yield and quality.

6. Harvest and storage

Autumn coriander can usually be harvested 40-60 days after sowing, and can be harvested intermittently or all at once. The frozen food is stored in the soil and then slowly thawed at 0-10℃ before eating to keep it fresh and tender.
