1. Growing environment: The quality of agricultural products is affected by environmental factors, such as light, temperature, humidity and climate. Different crops have different optimal growth environments, and only by growing in the optimal environment can the product quality be guaranteed. Dengfeng is located in hilly and mountainous areas, with poor land and water conservancy conditions, and the benefits of planting vegetables and fruits are not good.
2. Variety selection: It is very important to choose varieties that adapt to the local environment, so as to better adapt to the local soil, climate, pests and diseases. In the selection of varieties, we should also pay attention to the storage resistance, insect resistance, yield and quality of varieties. Zhaojun township in the west of Dengfeng has a large temperature difference between day and night, and the soil is rich in mineral elements such as medical stone, which is suitable for planting mustard. The mustard grown here is round, spicy and crisp.
