Agricultural experts have also studied this, mainly because organic fertilizer has played a miraculous role, making the soil better ventilated, the crop root system more developed and the natural absorption of nutrients more thorough. Of course, to grow such a big sweet potato, fertilization alone is definitely not enough, such as light, ambient temperature, moisture and soil environment, which are all very important. The ecological conditions in the countryside are better, and the old lady usually takes care of them, so she can finally harvest such a big sweet potato.
The news happened in Leshan, Sichuan. A 74-year-old woman in Baihe Village, Qianwei County actually planted a super-large sweet potato weighing 30 pounds in her own land, which suddenly attracted villagers to watch. It's not rare, but it's a miracle. Many farmers have worked hard all their lives and have never seen this sweet potato at all. The old one in my family weighs only a catty, not to mention the young one. Grandma Zhang Can is an eye-opener for everyone. It is said that this is not the first time the old lady has harvested such a big sweet potato. Last year, she planted a sweet potato weighing 18 Jin, which is already a record. Now she has broken this record again, and all the sweet potatoes in her family account for more than half of the weight, so I am not surprised at all.
Things spread to the internet, which also aroused the curiosity of many netizens. Why is grandma Zhang's sweet potato so big? Some agricultural experts have paid attention to this matter and conducted in-depth research. The conclusion is basically consistent with grandma Zhang, mainly because farm manure plays a great role. These organic fertilizers have greatly improved the soil environment and made the roots of crops particularly developed. In addition, the rural environment is relatively good, with plenty of water and sunshine, and the elderly are also very diligent. That's why we finally planted such a giant.
