 In summer, there are many thunderstorms, and many farmers often use thunderstorms to spread fertilizer to the crop fields. Studies have shown that it is not only unscientific, but also harmful to the application of fertilizer to crop seedlings.
1. Applying fertilizer in thunderstorms is easy to be struck by lightning.
The peasants applied fertilizers to the fields during thunderstorms. The time was concentrated, the labor was much more, the targets were exposed, and there were often unsafe accidents that were hit by lightning. In recent years, the phenomenon of lightning strikes by peasants in the summer rain season to the field work has occurred frequently, and the lessons are heavy.
Second, in the thunderstorm, the application of chemical fertilizer waste is serious
The peasants are exposed to thunder and rain, such as urea and compound fertilizer. After high temperature, light and water, they are quickly decomposed and evaporated in the surface layer of the soil. Only a small part of the soil is absorbed by the roots of the crop. In addition, strong rainfall can also cause a huge loss of fertilizer. In this way, the utilization rate of fertilizer in the thunderstorm days is very low, and a large amount of chemical fertilizer is wasted, which increases the investment cost of farmers' farming and wastes energy and materials. For the summer crops to apply fertilizer, it is best to open the ditch or apply the hole, the depth is 5~10 cm.
Third, the application of chemical fertilizers in thunderstorms is prone to disease
When some farmers use chemical fertilizers in thunderstorms, the maps are light and cool, and often do not wear rain gear, let the rain water drench the whole body. In this way, it is very easy to develop or induce various diseases such as colds, stomach diseases, and arthritis. Women working in thunderstorms and fields are also prone to gynecological diseases.
Farmers applying fertilizers in thunderstorms not only cause waste of fertilizers, but also harm the health of farmers' friends and even endanger life and safety.
