1. How many Jin per mu of sweet potato
1. Generally, the yield per mu of sweet potato can reach about 6, Jin, and the high yield can reach 1, Jin. Under conventional planting, the average yield of spring potato is 35 kg, and that of summer potato is 25 kg.
2. Because the specific yield of sweet potato may be affected by varieties, climate, planting techniques, planting time and other factors, if you want to obtain higher yield of sweet potato, you must master the correct planting techniques.

Second, when is the growth period of sweet potato
The growth period of spring potato is 16-2 days, and that of summer potato is about 11-12 days. According to the growth characteristics of red spring in the field and its relationship with climate conditions,

2. Mid-term (from pot sealing to the peak of stem and leaf growth)
Spring potato lasts about 5 days, and summer potato lasts about 3 days. At this stage, the tuberous roots expand slowly and the stems and leaves grow fast, which is a period of mainly growing stems and leaves.
