Sweet potato planting time, method and management

Sweet potato , also known as yams, is an easy crop to grow. It is drought resistant but not cold tolerant. If planted too early, the temperature will be too low to meet the growth needs and the sweet potatoes will enter a hibernation-like state, which can easily lead to underground rot. Let’s learn about the time, methods and management of sweet potato planting .

1. Planting time

1. Sweet potatoes need to be harvested in autumn and winter, so the growing period is longer. Usually seedlings and cuttings are required before formal growth can begin.

2. The planting time for sweet potatoes is from April to May in spring, and the best planting period is mid-May. At this time, the temperature is stable at around 15-20℃, which is conducive to the rapid germination of sweet potatoes.

2. Seed selection

The method of planting sweet potatoes is simple, but choosing good seeds is the key to high yield. When selecting seeds, you need to observe whether the sweet potato seed potatoes are healthy and disease-free, and choose varieties with larger size and more buds for planting.

3. Planting

1. Soak the sweet potato seed potatoes in the polysaccharide solution for about 10 minutes, then take them out and plant them. Be careful to distinguish the head and tail to prevent the seedlings from growing unevenly.

2. If you cannot distinguish the head and tail, place the seed potatoes at an angle, sprinkle a layer of dead grass and rotten wood on them, and then cover them with a small amount of soil.

3. If the temperature is not high enough, cover it with plastic film to keep it warm. When the sweet potato seedlings grow to 30-40cm, remove the plastic film, cut off the stems and leaves, and plant cuttings in sections with 3 leaves each.

4. When taking cuttings, the distance between each plant should be about 30cm.

4. Fertilization

1. Carry out the first fertilization after planting to promote the growth of new roots of the sweet potato seedlings . Human feces and urine water can be used.

2. The second fertilization should be done after the sweet potatoes have taken root, with an appropriate amount of urea to promote uniform growth of the seedlings.

3. The third fertilization is for seedling growth. Urea plus compound fertilizer can be used, followed by fruit-enhancing fertilizer, such as potassium fertilizer and boron fertilizer.

5. Shunmiao

1. In order to facilitate later harvesting and avoid excess branches and leaves consuming nutrients, the seedlings need to be straightened in time.

2. Arrange the sweet potato vines so that they grow in one direction, which makes it easier to harvest. When transplanting the seedlings, you can remove the excess branches and leaves.

6. Harvest

The harvesting time is from September to October. During this period, you can cut off the stems and leaves of the sweet potatoes, dig them out of the fields, and store them in cellars to prevent moisture from being lost.

The above is an introduction to the key points of time and methods for planting sweet potatoes . It is important to master management techniques when planting sweet potatoes so that the grown sweet potatoes can achieve high yields.
