What is the impact of heavy rain on agriculture? 1. Destroy farmland.
Heavy rain has a great impact on agriculture, which will flood some farmland orchards and collapse livestock pens. Heavy rain will cause water conservancy facilities to be washed away, causing serious harm. Rebuilding farmland, pens and water conservancy facilities requires a lot of manpower and material resources.
2, cause disease
Heavy rain will spread germs, make diseases and insect pests and livestock diseases more likely to occur, and affect the later production of aquaculture. Therefore, after the rainstorm, livestock and poultry should be given medicine in time to avoid being infected with diseases, and infected crop seedlings should be pulled out.
3. floods
Flooding caused by rainstorm will submerge crops and make them unable to metabolize normally. Crops in different growth stages have different resistance to waterlogging, among which the resistance at flowering stage is the weakest, followed by booting stage. Excessive rainstorm will make the water level of rivers and lakes soar and cause flash floods.
Step 4 tighten production
When the crop is in a rainstorm, the anther pollen of the plant will be destroyed, so that although heading and flowering, it will die without fruit, which will lead to a sharp increase in the empty shell rate of the crop and reduce the yield of the plant. Moreover, I am afraid that heavy rain will harden the soil and lead to poor respiration of crop roots.
