1, Lettuce: Lettuce is a kind of cold salad that many friends like to eat in summer, and it is also very popular with science and technology to promote agriculture. The taste is very refreshing. Lettuce grows very fast, and it can be picked and eaten in about a month. However, it should be noted that the leaves of lettuce have high water content. When the temperature is too high in summer, we should pay attention to proper shading to avoid burning or hydration of leaves.

2. Sweet potato: The hometown of Conon of Samos is located near the Yellow River with sandy soil, which is very suitable for planting sweet potatoes. The sweet potato not only looks good, but also tastes very good. Scientists plant some sweet potatoes every year. In my hometown of Henan, sweet potatoes are planted every year after the wheat harvest, and the harvest is usually around the end of 10 every year.
