Can I grow sweet potatoes in rainy days? What are the precautions when planting sweet potatoes?

Planting sweet potatoes in rainy days is easy to cause potato ridges to harden, especially when the seed holes are wet and pressed. After sunny days, the surrounding soil becomes dry and hardened, which is not conducive to the rooting of potato seedlings and slows down their emergence. Moreover, the rainy days are mild and the ground temperature is relatively low, which is not conducive to the rooting and seedling delay of potato seedlings. The cultivation of sweet potato is basically through early seedling raising and then cutting planting, and the cutting sweet potato seedlings have no roots in the early stage, so the soil needs to be very moist for cutting sweet potato seedlings.

Although there is no requirement for the growth environment of sweet potato seedlings, it requires high survival rate and high yield of sweet potato. You must choose loose, breathable, sandy loam and well-drained sand. In low-lying areas and places prone to water accumulation, the survival rate of planting sweet potato seedlings is low. When planting sweet potatoes, you should choose high-quality potato seedlings in the nursery. The seedlings are 20-25 cm high, with the top three leaves flush, thick stems and dark green. After the seedlings are raised, cutting off a short section of roots can promote early roots and more potatoes.

When planting sweet potato seedlings, the depth and nodes of soil have great influence on their survival. The soil below the surface/above kloc-0/0 cm has high temperature, good permeability and large temperature difference, which is beneficial to the survival of seedlings. In order to achieve high yield of sweet potato, it is best to apply some base fertilizer before planting sweet potato. For farmers with conditions, you can also sprinkle some plant ash, so that the sweet potato planted is not only big, but also sweeter.

Planting sweet potatoes requires deep ploughing and high ridges. 80% of sweet potato roots are distributed in the soil below 30 cm. Deep tillage can solve the problem of poor air permeability of soil below 25 cm, which is beneficial to the expansion of sweet potato. When planting sweet potatoes, it is best to choose after 3: 30 or 4: 00 in the afternoon. When you want to plant high-yield sweet potato seedlings, it is best to let the sweet potato seedlings lie 6 ~ 7 cm horizontally in the sweet potato kiln and then plant them vertically. There are many key factors for high yield of sweet potato, which are not as simple as planting methods. For example, seedling selection, soil properties and fertility, including the weather trend this year, are all related to the yield of sweet potatoes.
