Three Key Points of Coriander Seedling Management
First, the germination period of coriander is longer. It takes about 9 to 10 days from sowing to emergence. During the germination period of parsley, if it encounters fine weather after rain, it is easy to form a layer of “pot cake†on the seedbed (strengthening layer). ), seriously affect the emergence rate of coriander, vegetable farmers can ease by pouring a small amount of water to ensure the permeability of the soil in order to facilitate emergence. Second, when the coriander seedlings grow to 4 to 5 centimeters in height, they will be subjected to thinning. The vegetable grower can carry out the seedlings according to the spacing of 3 to 4 centimeters to ensure that the parsley has enough growth space, and the remaining seedlings are of the same size for easy management. In the case of thinning, we must combine the removal of field weeds. Third, the disease of parsley is less, because it is planted in the open, and now is the high incidence of insect pests, vegetable farmers should be the main prevention of pests, can be used 0.5% Avidin 4000 times solution or 2.5% vegetable suspension agent 1000 times solution Spray prevention, spray prevention once every 5 to 7 days can be. 10000Hz High Frequency LiDAR Module 10000 Hz is one of our 2021 new solutions products,which can be widely used in drone postioning, car anti-collision, intelligent traffic monitoring etc. with high accuracy.
