Therefore, if we do not pay attention to control the temperature, it is easy to appear the phenomenon of late spring cold, resulting in weak seedlings or even dead seedlings, so we should timely cover the sowing surface with plastic film, press the plastic film, and take measures to prevent cold and heat preservation. Promote seed germination and emergence, wait until the temperature gradually rises, open the plastic film, but when the temperature is too high, we should also pay attention to timely cooling.

2. Weeding between seedlings

When the seedlings were unearthed, the growth of all the seedlings was observed, and it was found that there were weak or dead seedlings in time, and then when the seedlings grew to about 9-11 cm, the seedling spacing was determined according to the different varieties. The excess weeds in the field should be removed, because the growth ability of weeds far exceeds that of seedlings, and the growth of weeds also requires a lot of nutrients and water.
