Question: This year, 20 mu of peanuts were planted. The leaves of peanuts grew well but there were a large number of pods. What are the reasons?
1. Excessive application of nitrogen fertilizer leads to peanuts growing in length. The obvious symptoms are thick green leaves compared to normal peanuts. 2. Heavy cropping of heavy crops, excessive application of potassium fertilizer, or no supplementation of calcium fertilizer for many years leading to fruit desiccation. Peanut straw is not resistant to burning; 3. Boron deficiency, the obvious symptoms are a large number of flowering at the flowering stage, and the actual fruiting rate (peanut shell) is small. 4. Injury or lack of light due to overcast days in the year.
