It is mainly due to uneven ground temperature and humidity, uneven bed surface, uneven thickness of cover soil, or bed and panel knots.
Prevention and control measures: 1 It is recommended to use the geothermal line or fire track to raise seedlings. When laying geothermal lines, the wiring distance between the greenhouse front lines is 5~6cm, and the distance between the back of the greenhouses is 8~10cm; the thickness of the cover soil should be even after the broadcast, and the bed should be seedbed. Cover the mulch and keep the humidity of the seedbed uniform; 3 When the seedlings are uneven or there are no signs of emergence, the seed in the seedbed should be inspected. If the tip of the radicle is rotted yellow, the seeds cannot germinate properly. Care should be taken to find the reasons and improve the seedbed environment. Conditions, and immediately replant; if the root tip is still white, indicating normal germination, should strengthen the management of temperature and humidity, and promote seed germination; 4 when the emergence of large and small seedlings, the seedlings can be moved to lower greenhouse temperature, Seedlings are placed in the greenhouse near the back wall so that seedlings grow neatly and consistently.
