In the process of growing cucumbers, we often encounter the problems of not growing seedlings or seedlings and seedlings of different sizes after sowing. Prevention measures include the following aspects:
First, do not blindly catch up early: Be sure to wait until the ground temperature stabilizes above 10°C and sow. When the soil temperature is too low, warming measures should be used to increase the seedbed soil temperature.
Second, the proportion of the preparation of nutritious soil should be appropriate: must use completely decomposed organic fertilizer, the proportion of fertilizer to be appropriate. Fertilizer dosage can not be too large to avoid burning seedlings.
Third, the irrigation should be uniform: too much water in the soil, the seeds are in a state of water soaking for a long time at a low temperature, will make the seeds rot.
Fourth, the bed surface requirements: the thickness of the cover soil should be maintained at about 1 cm, nutrient soil should be loose and detailed. If the surface of the seedbed is uneven, the thickness of the cover soil is uneven, even if the seed is exposed on the exposed surface, and the soil is overly thick, the phenomenon of uneven seedling emergence or no seedling emergence will occur.
5. Operate strictly according to the technical requirement of nursery: The dosage of pesticides selected for soil disinfection should not be too large. In addition, germinating cucumber seed germinated after sowing germination, generally 3 to 5 days after sowing, the seedlings can be released.
