Detailed Introduction to the Latest Growing Environment for Sweet Potato Slips
In China, sweet potato is both a food crop and a vegetable crop, and the demand for it in China is quite large. Not only do the tubers of sweet potato have considerable edible value, but sweet potato slips are also very popular. When planting, if the purpose is to produce sweet potato slips, then the surrounding growing environment is very important. So what is the growing environment for sweet potato slips? Now let's take a look together with the editor!
1. Moisture
Sweet potato has a fairly strong drought tolerance, but it still needs a certain amount of water during growth. Too much or too little water is very unfavorable for increasing sweet potato yields. Sweet potato has poor waterlogging tolerance, especially during the tuber formation stage; if it is flooded, then the yield will be seriously affected. If soil moisture is unstable, then the sweet potato tubers are very prone to skin cracking. At the same time, we must also control air humidity well. If humidity is too high, aerial roots are likely to appear on the stems of sweet potato slips, which will reduce the quality of the slips. Therefore, we should control air humidity well, water reasonably according to actual conditions, drain when there is too much water, and water when there is too little.
2. Temperature
Sweet potato likes to grow in a warm environment. When sweet potato seedlings are planted, in a soil layer of about 8 cm, if the temperature is 10 degrees, then they will basically not take root. At 15 degrees, it also takes 5 days to take root. If you want sweet potato to 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 stems and leaves grow. However, if the temperature is too high, it will still affect tuber expansion. The most suitable growing temperature for sweet potato slips is generally around 22-24 degrees. If it exceeds 20-30 degrees, it will affect tuber expansion, and then attention should be paid to maintaining a relatively large day-night temperature difference to promote tuberous root expansion and increase nutrient accumulation.
3. Light
Light is also very important for the growth of sweet potato. If light is suitable, it can enhance leaf color, prolong leaf age, and strengthen the growth ability of stems and vines. It is beneficial to the absorption and transport of nutrients, and the yield can also be significantly increased. If light is insufficient, then the leaves of sweet potato slips will clearly lose their color and a large number of leaves will fall, producing a growth situation completely opposite to that of sweet potato slips with sufficient light, and the yield will naturally be affected and decline. The suitable daily light duration is very important for the growth of stems and leaves, so everyone must pay more attention.
4. Soil
When planting sweet potato, the choice of soil naturally also requires our special attention. Generally, sweet potato is suitable for growing in sandy soil with strong permeability, good drainage and irrigation, and rich humus. If the soil is too sticky and heavy, then the quality of the tuberous roots will clearly decline, and the quality of the sweet potato slips will also be affected. Not only will the yield be low, but it will also affect their storability. However, it should be noted that sandy soil generally does not have very good fertilizer and water retention capacity, so attention should be paid to gradual fertilization to improve soil fertility. Then the soil pH value should be controlled at around 5.5-6.5. If the soil salt content exceeds 0.2%, then it is not suitable for planting sweet potato.
The above is a brief introduction to the growing environment for sweet potato slips. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
