1, the yield increase effect is obvious. Compared with the common sweet potato of the same variety, the yield of virus-free sweet potato can reach 20%-200%, and the specific yield increase range varies with the tolerance of varieties to virus infection. The more serious the virus infection, the greater the yield increase after detoxification.
2. so cute. Compared with virus-free sweet potato, the seedling emergence was earlier 1-2 days, the seedling emergence increased by about 25%, and the weight of 100 seedlings increased by more than 30%.
3. Strong nutrition. Compared with virus-free sweet potato, virus-free sweet potato has the advantages of fast survival, early ridge sealing, short stem nodes, thick leaves and high fresh weight of stems and leaves. The drought resistance is obviously improved.
4, early potatoes, rapid expansion. It was 7- 10 days earlier than ordinary sweet potato, and the swelling speed of potato pieces was always higher than that of ordinary sweet potato.
5. The commodity rate of potato is high. Virus-free sweet potatoes are neat and concentrated, with smooth skin and bright color.
6. Good quality. The drying rate increased by 1-2 percentage points, and the powder yield also increased by about 2%.
7. Storage resistance. The resistance of virus-free sweet potato to diseases such as nematodiasis, black spot and black spot is obviously improved. Under the same storage conditions, the intact rate of virus-free sweet potato tuber is 20%-55% higher than that of common sweet potato.
8. The economic benefits are considerable. According to the average yield increase of 30%, planting virus-free sweet potatoes can produce more than 500 kilograms of fresh potatoes per mu every year, which can increase the income by more than 200 yuan per mu.
