1. Environmental changes cause slow adaptation
The root system after planting the seedlings is transplanted from the seedling substrate to the soil at once, which requires a gradual adaptation process. Once the soil environment deteriorates severely, the root system in the seedling substrate cannot adapt to the soil environment, and the root system of the seedlings is difficult to lay down.
The longer the greenhouse is planted, the worse the soil environment will be, and there will be many more and more bad problems. The vegetable seedlings after planting will cause poor root growth due to the huge environmental changes from the substrate to the soil. . A healthy and balanced soil environment is the basis for the smooth rooting of vegetable seedlings after transplanting.
2. Fertilizer is too concentrated
The fertilizer is too concentrated. After the seedling water is poured, the soil solution concentration is too high. The roots are separated in the high concentration soil solution, resulting in water shortage, which eventually leads to root death.
3. The surface temperature is too high
The temperature of the soil suitable for root growth is generally between 20 and 22 °C. In summer, the glare is direct. After the plant is planted, appropriate shading should be carried out, not only to reduce the transpiration of the leaves, but also to keep the soil temperature in the condition of suitable root growth. .
In addition, the poor growth of the roots of the seedlings itself is also the reason why it is difficult to take root after planting. After the seedlings, the growth of the roots of the seedlings should be carefully observed. The strong roots are white and developed, and the best for the root hairs and yellowing and browning. No need to.
