Now has entered the spring season, many farmers have begun to prepare pepper, cucumber, tomato and other vegetables seedling problem. Last week, we conducted hole sowing of cucumber seeds to test the characteristics of the variety.
However, during vegetable seedling cultivation, low temperatures, insufficient light, and high humidity are often encountered, which can cause problems in seedling cultivation and affect the normal growth of vegetables. So, what should be paid attention to in early spring vegetable seedling cultivation?
1、 Pay attention to bed temperature: chili peppers should be controlled at 18-20 ℃ during the day and 14-16 ℃ at night; The bed temperature control of tomatoes should be about 2 ℃ lower than that of chili peppers. At the same time as cooling down, it is necessary to strictly prevent seedlings from freezing.
2、 Reduce humidity: If the bed soil is too wet, the seedlings have fewer fibrous roots, which not only makes them prone to elongation, but also easily induces diseases such as sudden death and gray mold. It is generally advisable to control the moisture content of the bed soil between 60% -80%. The air humidity should not be too high, and the general relative humidity is recommended to be 60% -70%. The main method to reduce air humidity is ventilation, and it is important to ensure that the ventilation port is facing away from the wind direction.
3、 Strengthen lighting: Under suitable temperature conditions, try to expose seedlings to as much sunlight as possible. When the temperature is not too low, try to peel off the film inside the shed as early as possible in the morning and delay covering the film as much as possible in the afternoon.
That's all for the precautions of early spring vegetable seedling cultivation. In early spring, pre seedling work is carried out on vegetables to prepare for high yield and look forward to a bountiful harvest!
