The growth environment of the latest sweet potato seedlings

Sweet potato is not only a food crop but also a vegetable crop in our country, the demand in our country is still relatively large. Among them, sweet potato not only has great edible value, but also sweet potato seedlings are very popular. When planting, if the purpose is for sweet potato seedlings, then the surrounding planting environment is very important. So what is the growing environment of sweet potato seedlings? Let's take a look at it with the editor.

1. Moisture

The drought tolerance of sweet potato is still strong, but it still needs a certain amount of water in its growth. Too much and too little water is very disadvantageous to the yield of sweet potato, and the waterlogging tolerance of sweet potato is poor, especially in the tuber forming period, if it is flooded, then the yield will be seriously affected. If the soil moisture is unstable, then sweet potato pieces are very easy to crack. At the same time, we also need to control the air humidity, if the humidity is too high, air roots are easy to appear on the stems of sweet potato seedlings, which will reduce the quality of sweet potato seedlings. Therefore, we should control the air humidity, water reasonably according to the actual situation, more water drainage, less water watering.

2. Temperature

Sweet potato likes to grow in a warm environment. When sweet potato seedlings are planted in a soil layer of about 8 centimeters, if the temperature is 10 degrees, then basically will not take root. 15 degrees also takes 5 days to take root, if you want sweet potatoes to take root normally, it should be controlled above 18 degrees. At 25 degrees, the growth rate of stems and leaves is relatively fast, the higher the temperature, the faster the growth of stems and leaves. However, if the temperature is too high, it will still affect the expansion of sweet potato cubes, in which the most suitable growth temperature of sweet potato seedlings is generally about 22-24 degrees. If it exceeds 20-30 degrees, it will affect the expansion of potato lumps, and then we should pay attention to maintain a large temperature difference between day and night, promote root expansion and improve nutrition accumulation.

3. Lighting

Light is also very important for the growth of sweet potato. If the light is suitable, it can enhance the color of leaves, prolong the age of leaves, and enhance the growth ability of stems. It is beneficial to the absorption and transportation of nutrients, and the yield can also be significantly increased. If the light is insufficient, then the leaves of sweet potato seedlings will obviously lose their color and produce a large number of fallen leaves, which is completely opposite to the growth of sweet potato seedlings with sufficient light, and the yield will naturally be affected and decreased. The appropriate light time every day is very important for the growth of stems and leaves, so we must pay more attention to it.

4. Soil

When planting sweet potatoes, the choice of soil naturally requires our attention. Generally, sweet potato is suitable to grow on sandy soil with high permeability, good drainage and irrigation and rich humus. If the soil is too sticky and heavy, then the quality of the root tuber will be significantly decreased, and the quality of sweet potato seedlings will also be affected, not only the yield is low, but also affect its storability. However, it should be noted that the fertilizer and water conservation capacity of sandy soil is generally not very good, so we should pay attention to step-by-step fertilization to improve soil fertility. Then the PH value of the soil should be controlled at about 5.5-6.5, and if the soil salt content exceeds 0.2%, it is not suitable to grow sweet potatoes.

The above is a brief introduction to the growth environment of sweet potato seedlings. That's all for today's introduction. This article is for reference only. I hope it can help you all.
