In recent years, the phenomenon of farmers being struck by lightning in the summer rain season has occurred from time to time, and the lesson is heavy. Second, in the thunderstorm days, the fertilizer waste is serious. The urea and compound fertilizer scattered by farmers against thunderstorms are decomposed and volatilized quickly in the soil surface after high temperature, light and water dissolution, and only a very small part is absorbed by the roots of crops. Heavy rainfall can also cause a large loss of fertilizer. In this way, the utilization rate of fertilizer scattered in thunderstorm days is very low, a large amount of fertilizer is wasted in vain, increasing the investment cost of farmers in farming and wasting energy materials. Apply chemical fertilizer to summer crops, preferably in furrows or holes, with a depth of 5 to 10 cm. Third, in the thunderstorm days easy to suffer from chemical fertilizer disease, some farmers in the thunderstorm days when fertilizer, light, cool often do not wear rain gear, let the rain shower the whole body. In this way, it is very easy to suffer from or induce colds, stomach problems, arthritis and other diseases. Women working in the field during thunderstorms are also prone to gynecological diseases.
