Consultation: I planted some bamboo shoots a few days ago. I was raining in the evening. The seedlings came out very well. After the rain, there was almost no seedling. What are the reasons? Answer: This is because after the first batch of planting met with rainfall, the ground temperature decreased, and the water was sufficient. In the raindrops, the seeds were tightly bound to the soil. The seeds quickly absorbed water and the seeds germinated, so the seedlings emerged faster. After the rain, the batch of rainwater had a rapid rise in temperature, and the water quickly evaporated. The conditions were not conducive to seed germination, so the emergence rate declined. Lettuce is a cold-type vegetable, so it is important to pay attention to cooling (especially soil temperature) in the summer and autumn seasons. The suitable temperature for seedling growth is 12～20°C. When the average temperature reaches about 24°C, the growth is still strong, but the temperature is too high. Especially when the surface temperature is as high as 40°C, the seedling stems are burnt and fall down, so the autumn lettuce seedlings Shading should be cool.
