According to its cultivation season, sweet potato can be divided into summer, autumn potato, winter potato and spring potato. Among them, summer, autumn potato and winter potato are the main ones. There are not many spring potatoes. Different seasons plant sweet potato, its climatic conditions are different, and its reproductive characteristics are different. The following small series of Huinong.com will introduce high-yield planting techniques for summer and autumn. Summer and autumn potatoes are planted in July and August, and harvested from December to January. The climate during the growth period is characterized by high to low temperatures, and the rainfall is from high to low. The whole growth period is sunny and the solar radiation is large. The effective accumulated temperature is high. The temperature in the middle and early period of fertility is higher, which is conducive to the growth of stems and leaves. The temperature difference between day and night in the middle and late growth of fertility is conducive to the expansion of potato tubers, higher yield and stable yield. 2. What farming and cultivation systems are suitable for planting summer and autumn potatoes? Such as paddy rice, potato planting in paddy fields, or rice, bean, potato planting, peanuts in dry land, sweet potato seedlings, or soybeans, sweet potato rounds, etc., to improve land use, to play the advantages of various crops, and to prove the effect Good. However, due to the high temperature, rain and moisture in the early stage of summer and autumn, it is conducive to the occurrence and development of yam disease; the later drought and less rain, especially in the year of severe autumn drought (especially in the north), is unfavorable for the growth and yield of summer and autumn potato. 3. Summer and autumn potato should pay attention to the following points in cultivation: 3 Select the corresponding excellent varieties, such as high-yield and high-humidity high-yield varieties for early summer and autumn planting, and high-yield varieties with early maturity and cold resistance for late summer and autumn planting. With the improvement of people's living standards, they must be selected. High-quality varieties, that is, varieties with high fragrance, sweetness, powder, softness, high vitamin and protein content, in addition to high dry matter rate.

The location of summer and autumn potato planting needs to be based on local climate, soil and other conditions, such as the southeastern coastal and southwestern regions of Guangdong Province.
First, the climate in these areas is warm, and the high yield performance of sweet potato can be fully utilized;
Second, the soil in the coastal areas is mostly sandy loam, which has become a high-yield sweet potato distribution area;
Third, sweet potato is more resistant to wind damage, and it is easy to stabilize and produce high yield. 
2 According to the length of the planting period, the corresponding measures are adopted. For example, the summer heat to the summer heat planting is in the high temperature and rainy season, which is conducive to the growth of stems and leaves. Therefore, it is necessary to adopt the measures of “pre-control and post-promotion†in the cultivation to prevent the stems and leaves from growing. Yield. If planted after the summer, the growth period of stems and leaves is short, and the growth of stems and leaves is insufficient. In the cultivation, measures must be taken to promote the main seedlings, such as inserting the number of seedlings, applying enough base fertilizer, and timely irrigation.
