Planting skills of sweet potato

There are many food crops in our country, such as corn, rice and sweet potato, which play an important role in our life. But compared with sweet potatoes, the cultivation of other food crops is more troublesome. Because the growth ability and adaptability of sweet potato is strong, it does not need to be observed every day, but growing sweet potato actually requires some skills. Today, the editor brings you the planting skills of sweet potatoes. Let's have a look!

1. Accelerating budding and raising seedlings

As we all know, if you want to grow sweet potatoes with high yield and good quality, they are closely related to the seeds. First of all, when choosing seed potatoes, you should choose medium size, smooth surface, no obvious scars and potholes. After selection, it was placed in the seedling hole to ensure the temperature and humidity of the soil and provide a good environment for seedling cultivation. Then cover a layer of soil and plastic film on heatstroke to improve the water and fertilizer conservation of the soil. Do a good job of seed potato sprouting and seedling cultivation to ensure the robust growth of sweet potato plants and lay a solid foundation for later yield.

2. Sowing time

Controlling the sowing time of sweet potato can effectively improve the yield of sweet potato. When the planting environment is fully satisfied, we can sow early appropriately. Early sowing time can prolong the growth period of sweet potato, which is beneficial to the expansion, quality and weight of sweet potato. So that the yield of sweet potato is more, which can also improve the economic benefits of planting. However, it should be noted that only in the right time or early sowing, not too late planting, sowing too late will affect the expansion and sugar content of sweet potato, reduce the commercial value and yield of sweet potato.

3. Check and select seedlings

The emergence of sweet potato seedlings must be observed in time after sowing and emergence, which is very important for the selection of seedlings. We should pull out the small seedlings that are too weak in time, and choose those sturdy and strong seedlings as planting seedlings. Because even if those weak seedlings survive, their yield will be terrible, not only to consume too much nutrients, but also other healthy seedlings to compete for nutrients, which is harmful but not beneficial. When planting, the main planting depth is about 5 cm, so that the growth of seedlings can be ensured and the yield can be increased.

4. Covering plastic film

After planting the seedlings should be covered with plastic film in time, the main purpose is to strengthen the soil water and fertilizer conservation, prevent the loss of water and fertilizer, resulting in the hindrance of seedling growth. Maintain the surface temperature of the soil and promote the growth of seedlings. At the same time, it can also effectively prevent the invasion of bacteria and reduce the incidence. Improve the survival rate of seedlings. After covering the plastic film, it is necessary to water and fertilize the seedlings in time according to the growth of the seedlings. Sweet potato has a large demand for potassium, so the proportion of potassium fertilizer can be increased appropriately to ensure the expansion of the rhizome.

The above is a brief introduction of sweet potato planting skills, the environment for growing sweet potato is very simple. However, the growth rate of sweet potato is slow, although there is no need for growers, so everything needs to be prepared before planting. The growth of sweet potato in the early stage is very important. I hope everyone can pay attention to it. That's all for today's introduction. This article is for reference only. I hope it can help you. Thank you for your reading and support.
