How many days does lettuce sprout and rapeseed sprouts, and how many days does rapeseed sprout?

Lettuce seeds germinate about ten days after sowing.

The germination time of lettuce seeds is determined by the surrounding growing environment, and if the environment is warm and the soil is dry, the germination time of the seeds will be delayed. If you want lettuce seeds to germinate quickly, you can germinate the seeds before sowing, soak the seeds in warm water for 7 to 8 hours, and then place them in a cool and ventilated place to dry, and then sow them, which can improve the emergence rate of lettuce.

The growth habit of lettuce.

Temperature: Lettuce likes a cool environment, the most suitable temperature is 15 20, it does not like high temperatures, can not exceed 25, if it exceeds this limit, it will affect its quality, making it very bitter.

Moisture: Lettuce in the growth stage, the water demand is relatively large, if there is a long-term lack of water, it will become very bitter, the quality is also very poor, however, in the replenishment of sufficient water at the same time, can not accumulate too much water, otherwise it will lead to root rot, affecting the growth of the future.

Nutrients: lettuce's requirements for fertilizer, mainly nitrogen fertilizer, when planting, the soil needs to be mixed with a sufficient amount of nitrogen fertilizer, in its growth stage, if the growth becomes weaker, it is also necessary to supplement some fertilizer in time.

Lettuce seeds can germinate about 10 days after they are planted. Note that after sowing, it is necessary to provide a growth environment of 15 degrees to 20 degrees, if it is higher than 25 degrees, the water absorption of the seed coat will be hindered, which will delay the germination time and make the germination poor.

Lettuce seeds can germinate in about ten days. Note that when choosing a sowing time, you should first understand the instructions for lettuce seeds, and then sow them in combination with the local climate.

In three or four days to a week, lettuce seeds germinate at a high rate and at a fast rate.
