In winter and spring seasons, seedlings often appear abnormal due to weather changes or improper management, mainly including:
1, root seedlings. Mainly due to high humidity and low temperature.
2, long seedlings. It is mainly caused by high temperature and high humidity.
3, aging seedlings. The age of seedlings is too large or the time of seedlings is too long.
4, frozen seedlings. Caused by too low a temperature.
5, drug seedlings. The application amount is too large and the concentration is too high.
6, wilt seedlings. The continuous rainy and snowy days suddenly caused the curtains to open.
7, wear hat seedlings. The seedbed was dry and covered with thin soil.
To control these abnormal conditions, control the temperature and humidity when raising the seedlings. When the temperature is too low, use geothermal lines and other measures to try to increase the temperature of the soil, avoid excessive humidity on the seedbed, and strictly control the seedling age. If there is a disease, use a concentration when spraying, and avoid using too much of the drug.
