Problems solved by technology

[0002] Sweet potato has a great planting coverage rate in the vast rural areas of our country. For a long time in history, sweet potato has become the staple food of the masses of people, and it is also a good feed for raising livestock in rural areas of our country; sweet potato is rich in nutrition, rich in starch and sugar. Sweet potato, protein, vitamin, cellulose and various amino acids are very good nutritious food; but in the prior art, when sweet potato is planted, it will be affected by a variety of viruses, thereby inhibiting the growth of sweet potato and causing seed property Degradation, which in turn causes the yield of sweet potatoes to decrease year by year, reducing the economic benefits of growers

Abstract

The invention provides a cultivation method of virus-free sweet potatoes. The cultivation method is characterized by comprising the following steps: (1) selecting and preparing a land; (2) cultivatingvirus-free seedlings; (3) transplanting seedlings; (4) carrying out field management; and (5) harvesting at proper time. The virus-free sweet potato seedlings cultivated by the cultivation method provided by the invention are rapid in survival, high in survival rate and strong in growth vigor, and the yield of the sweet potatoes is effectively improved; and moreover, the grown sweet potatoes aregreen and healthy, good in mouth feel and complete in nutrient elements, and the economic benefits of planters are improved.

Description

technical field [0001] The invention relates to the technical field of sweet potato cultivation, in particular to a cultivation method of virus-free sweet potato. Background technique [0002] Sweet potato has a great planting coverage in the vast rural areas of our country. For a long time in history, sweet potato has become the staple food of the masses of people, and it is also the best feed for livestock in rural my country; sweet potato is rich in nutrients, rich in starch, sugar However, in the prior art, sweet potatoes are affected by various viruses when they are planted, thus inhibiting the growth of sweet potatoes, resulting in Degradation, which in turn leads to less sweet potato yields year after year, reducing the economic benefits of growers. SUMMARY OF THE INVENTION [0003] The present invention is aimed at the above technical problems, and provides a cultivation method of virus-free sweet potato. [0004] In order to achieve the above object, the present i...
