How to manage the cultivation of coriander in open field?

How to manage open field coriander cultivation? Please guide the management method of open-air planting coriander can refer to the following: First, the germination period of coriander is long, it takes about 9~10 days from sowing to emergence. In the germination period of coriander, if it encounters sunny weather after rain, it is easy to form a layer of "pot cake" on the seedbed, which seriously affects the emergence rate of coriander. Vegetable farmers can ensure the permeability of the soil by pouring a small amount of water to facilitate emergence. Second, when the coriander grows to 4~5 cm high, it should be thinned. Vegetable farmers can thin seedlings according to the plant spacing of 3~4 cm to ensure that coriander has enough growth space, and the seedlings should be consistent in size for easy management. Thinning should be combined with weeding. Third, there are fewer diseases in coriander. Because it is open field planting, and now it is the high incidence period of pests, vegetable farmers should give priority to pest prevention, which can be prevented by using 0.5% emamectin 4000 times solution or 2.5% Caixi suspension 1000 times solution every 5~7 days.
