1. Variety selection

There are large-leaf varieties and small-leaf varieties of coriander. Large-leaf varieties have tall plants, large leaves, light fragrance and higher yields. Small-leaf varieties have shorter plants, smaller leaves, strong fragrance, cold resistance, strong adaptability, and slightly lower yields. Generally, small-leaf varieties are mostly selected for spring and autumn cultivation, and large-leaf varieties are selected in summer.

2. Plot selection and soil preparation and fertilization

Plots for planting coriander should be fertile, loose, well-drained, and moist plots. The land must be plowed and sufficient fertilizer should be applied. As base fertilizer, apply 2000-2500 kilograms of decomposed farmyard manure per acre. Plow the fertilizer into the soil and rake it flat to make a high bed with a bed width of 1.2-1.5 meters and a furrow width of 30 cm. The soil on the bed surface needs to be finely crushed, loose and flat.

3. Seed treatment

Before sowing, rub the seeds into single seeds by hand.

4. Sowing

Coriander is generally sown by broadcast, but drill sowing can also be used. Rake the land flat to make a sorghum and then spread it. Use 1.5 kilograms of seeds per acre, add an appropriate amount of pakchoi seeds, mix them and spread them evenly. The pakchoi can provide shade for the coriander seedlings, and the pakchoi can be pulled out during thinning.

5. Field management

It is not advisable to water too much during the seedling stage. Start watering and topdressing with decomposed manure water or urea when the seedlings are 2 centimeters tall. After the plants are 10 centimeters tall and enter a period of vigorous growth, water and fertilize frequently to keep the soil surface moist. In rainy days, timely drainage is required to prevent waterlogging. Pay attention to cultivating and proper thinning, and pull out weeds during thinning.
