For half a day, it is suitable for planting vegetables that like light and shade, such as onion, oil wheat, leek, loofah, coriander and radish. However, when facing west in summer, the temperature is high, which causes some vegetables to be scorched by the sun, and the light leaves fall and the heavy ones die. Therefore, it is best to plant high-temperature resistant vines. According to experience, in the hot summer in Guangdong, it is better to grow vegetables in the vegetable field facing the east fence than in the vegetable field with sufficient sunshine, because not only the sunshine time is sufficient, but also the shadow of the fence has begun to block the sunlight entering the vegetable field when the sun is strongest in the west every afternoon.
