What should we pay attention to in rainy and solar farming?

1, before and after the rain. Winter wheat in the Yellow River basin will gradually turn green from south to north, rape and wheat in the south of the Yangtze River will grow faster, and the demand for water is relatively high. However, the precipitation in North China, Northwest China and Huanghuai areas is generally less, which often cannot meet the needs of crops. If there is little rain in early spring, spring irrigation in time after the rain can achieve good results, that is, the agricultural proverb "Spring rain is as expensive as oil" often says: "Rain and dew make crops good, and Koharu in Da Chun is a treasure."

2. At this time, the seedling raising of double-cropping early rice in South China has started. In order to prevent the harm of cold and hot weather and cold weather, we should pay attention to the "cold tail and warm head" weather and seize the sunny sowing. In addition, in the south, although the weather is warm, the temperature in early spring is still changeable. Before and after the rain, we must manage tomato seedlings, eggplant seedlings and pepper seedlings, pay attention to ventilation, prevent stuffy seedlings, pay attention to controlling fertilizer and water, and prevent seedlings from growing white.
