Abstract

The invention relates to the technical field of agricultural production, in particular to a fresh sweet potato and a culture method thereof. By comprehensively considering the planting period of the sweet potato and conducting selecting, preparing, fertilizer applying, ridging, planting and field managing on a planting land, a big-ridge, single-line, parallel-shallow-planting and increased-planting-density culture method is put forward. It is proved through big field tests that the method can improve the yield and commodity rate of the sweet potato, increase farmer income and improve plantingefficiency compared with a traditional method. A new effectively technological means is provided for planting the sweet potato in a southern potato area, and a basis is laid for the standardization, large-scale and modernization of the sweet potato planting technology.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a fresh sweet potato and a cultivation method thereof. Background technique [0002] Sweet potato (Ipomoea batatas (L.) Lam.) is a short-day crop that likes warmth and fears cold. It is resistant to drought and barrenness. It can be planted all year round in Hainan. It is planted in mid-autumn and winter. It is an off-season product in the interior when harvested. It has an off-season price advantage. With the continuous improvement of people's living standards, the health function of sweet potato is more and more favored by consumers. It has changed from a coarse grain that solves hunger in the traditional concept to a health food that is rich in nutrition, has the functions of anti-cancer and enhancing immunity. At the same time, people have higher and higher requirements for commercial potatoes, not only for delicious food, but also for fruit type and size. H...
