Key points of medium-term Management of seed Sweet Potato
Most areas of drought prevention and drainage are hot and rainy, the stems and leaves on the ground of sweet potato grow rapidly, and the nutrients go up but not down. At this time, attention should be paid to drainage, that is, timely removal of stagnant water on the ground after rain to control the vigorous growth of the aboveground. Some droughts need to be watered to prevent drought, so that potato pieces can not be wet.

A brief discussion on the key points of High-yield cultivation of Film-mulched Sweet Potato
First, select suitable plots to increase fertilizer. It is best to choose fertile and irrigated loam to plant sweet potatoes. The ploughing layer of the land covered with plastic film should be deepened, the depth of turning over the soil in autumn is about 25 cm, and more than 2500 kg of high-quality mature farm manure should be applied per mu. When ploughing and ploughing, the fertilizer should be spread and applied.

Selection, retention and storage of sweet potato species
Timely harvest sweet potato harvest is too early, the yield is low; too late harvest, easy to suffer from freezing, affecting storage. Therefore, it is generally best to start harvesting when the temperature is about 18 ℃, and finish harvesting when the temperature is above 10 ℃ (that is, before the dry frost period). Spring melon fields for dry use are usually harvested first.
