Before and after the Ching Ming Festival, the farmers began a new round of farming. Many people in the countryside grow sweet potatoes, so now every region has seen farmers preparing sweet potato plants. For planting sweet potato seedlings, do you know whether it is shallow or well planted? When is it planted? Let's take a look at it.
1. Judging method of shallow planting or deep planting
The depth of sweet potato seedlings should be determined according to the local soil conditions. If the soil is relatively poor, it is a sandy land or a hilly land with less fertility. Usually, irrigation is also very inconvenient, and it should be properly planted in some sand land areas. There is a saying that "deep planting a gold ingot, planting a pile of grass in the first place."
However, if it is a place with deep soil fertility, convenient irrigation, and high temperature, it should be properly planted. In many areas, there are the sayings of “deep planting seedlings and shallow planting of potatoesâ€.
Deeply planted in places where barrenness, inconvenient irrigation, and low temperature are required, mainly to allow the sweet potato seedlings to quickly root after planting. The sweet potato seedlings are deep, and the sweet potato roots are also deep, which can absorb deep nutrients in the soil. Moisture. In places with deep fertility, convenient irrigation and high temperature, the shallow sweet potato can effectively stimulate the development and expansion of sweet potato roots because of the large temperature difference between day and night.
2, the time of sweet potato seedlings suitable for planting
Generally, sweet potato seedlings are planted on cloudy days, mainly because sweet potato seedlings have no roots when planted. If the sweet potato roots are not grown after the sunny day, the sweet potato leaves have evaporated under the sun, but they cannot be under the sun. When it rains, although there is enough water in the rain to ensure the survival rate of sweet potato seedlings, it is easy to form the roots of the sweet potato seedlings on heavy rainy days, affecting the quality and yield of sweet potatoes, so it is best to rain on cloudy days or under the rain. After planting.
3. When sweet potato seedlings are planted, they should be poured with fixed water.
When planting sweet potato seedlings, it is necessary to pour enough root water to cover the mulch film after pouring the root water. The mulch film can be kept warm and moisturized. Generally, the sweet potato seedlings can grow roots 2-3 days after covering the mulch film. Be careful when planting and rooting the sweet potato seedlings. Do not let the leaves stain the soil, which will affect the survival of the sweet potato seedlings.
The sweet potato has high drought tolerance. After the sweet potato seedlings are planted, the sweet potato can be irrigated according to the growth of the sweet potato and the water content of the soil. When the sweet potato is rapidly developed, the water needs to be relatively large. At other times, the water can be appropriately reduced to increase the sweet potato. Dry matter accumulation enhances the quality and yield of sweet potatoes.
The above is the introduction of sweet potato seedlings. For shallow planting or deep planting, we must master the time and skills, and also pay attention to the planting methods. I hope that the shared content can help the majority of sweet potato growers.
