When is the most suitable time for sweet potato seedling?

As the old saying goes, "A day's plan lies in the morning, and a year's plan lies in the spring", after a winter's recuperation, the cold winter is over, and the warm spring is coming, and the hardworking farmers are going to start to be busy with spring plowing and spring sowing again. As an important cash crop, sweet potato is planted in many areas of China. Especially in the past, every family in the countryside are raising pigs in the era, sweet potato is a must plant a crop. That sweet potato seedling is when the most appropriate?

Sweet potato seedling time

On the farmer's old side of the family, every family used to grow a lot of sweet potatoes. Most of them were used for pigs, and the rest were eaten by people or processed into agricultural products for sale. Because the amount of planting is relatively large, so most of them are home-grown seedlings, and few people buy sweet potato seedlings. Every year, after the beginning of spring, at the end of February and the beginning of March, they will pick up the carefully selected sweet potato seeds from the cellar and start to raise seedlings.

Old-timers engaged in farming are organized according to the twenty-four seasons, and spring sweet potato seedlings are commonly planted around the time of hibernation. However, different climatic conditions in different places, seedling time will be somewhat different, according to experience, it is best to seedling before 45 days before planting. For example, in the area south of the Huaihe River in mid-February after the start of seedling, while the area north of the Huaihe River in April 10 before the end of seedling. Because the temperature is still relatively low during this period, sweet potato is mainly covered with plastic film to breed.

Sweet potato seedling method:

Sweet potato seedling method, I believe that farmers and friends are more familiar with, and is not too complicated, and its mainly divided into sweet potato seed selection, seedbed layout, sweet potato seed treatment and sweet potato row seed technology.

As I said earlier, the rural areas basically keep their own sweet potato seeds. When spring arrives, the sweet potatoes saved for planting before will be picked up from the cellar, and then choose the ones with smooth skin, bright-colored skin, even lumps, medium size, free of diseases and injuries, free of cold and wet damage, and with a lot of white pulp for seed.

After selecting the sweet potato seeds, it is time to set up the seedbed. Seedling bed is recommended to choose a germ-free and disease-free and sunny plots of land is appropriate, leveled out after the top of some rotting livestock manure, such as cattle, horse, pig manure are available, and need to pay attention to the bed soil is not easy to be too thin or too thick, it is recommended that the 5-8 cm is appropriate.

The third step is to soak the sweet potato seeds. In the past in fact are not this step, but now is concerned about the scientific planting, there are some professional growers will be in order to prevent the seed potato with disease, will use warm water or medicine to soak the seed, but also can be directly sprinkled directly on the seedbed.

The last step is the sweet potato seed row technology. The more common are slant row, flat row and straight row of these three ways, which is more widely used is the slant row and flat row is mainly. In rows of sweet potato to master the method, the principle is that large potatoes dense rows, small potatoes sparse rows, which is more convenient for seedbed management. After the row, remember to cover the plastic film.
