It is not appropriate to blindly promote the live cutting of sweet potato
The research on sweet potato diced planting has been for several decades. Although there have been many reports of increased production, the area of ​​utilization of the sweet potato has not been utilized. There are five main reasons: First, the sweet potato tuber contains high soluble sugar, which is easily rotted after incision. The second is that in the north, it can only be grown as a spring potato. It takes a long time to grow soil from the tuber into the seedlings. In the southern part of the country, the crops are often connected tightly and there is no longer time in the field. After the broadcast, it is also vulnerable to the harm of small animals. The third is that cutting live broadcasts will bring diseases of seed potatoes to the field, which will increase the risk of disease accumulation. The fourth is that there are differences in the emergence time of field potato stalks and the quality is very different. This kind of non-uniformity will seriously affect the output, and it is technically difficult to eliminate this difference. The fifth is the use of seed and the amount of labor is relatively large, generally more than 100 kilograms per acre need to use more than 20 to 30 centimeters in the potato seedlings need to clear the mother potatoes, more time-consuming. Due to the above factors, cutting live broadcasts should not be promoted in production until the research has achieved more successful technologies.
