Consultation: I planted some bamboo shoots a few days ago. After a rain in the evening, the seedlings were very good. After the rain, I planted a batch of almost no seedlings. What is the reason? Answer: This is because the first batch of seedlings encountered rain, the ground temperature decreased, the water was sufficient, and the seeds were tightly combined with the soil under the tapping of the raindrops. The seeds quickly absorbed water and the seeds were germinated so that the seedlings emerged faster. After the rain, the batches rose rapidly due to the rain and the temperature quickly evaporated. The conditions were not conducive to the germination of the seeds, so the emergence rate decreased. Lettuce is a cold-type vegetable, and it is necessary to pay attention to cooling (especially soil temperature) in summer and autumn high-temperature seasons. The suitable temperature for seedling growth is 12-20 °C. When the average temperature of the day 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 stem of the seedling is burned and the seedling is poured, so the autumn lettuce shoots It should be shaded and cooled.
