Every spring, it is a good time for vegetable growers to start cultivating vegetable seedlings. However, in the low temperature environment of spring, all vegetable seedlings need to be cultivated indoors or in greenhouses and arched sheds. Temperature, humidity, light and other aspects need to be artificially controlled, which requires growers to have certain knowledge. If it is not properly managed, vegetable seedlings are prone to various problems, such as weak seedlings, blight, cataplexy, tall seedlings and so on. So, what do we need to pay attention to when cultivating vegetable seedlings? Next, I will introduce you to the six taboos, I hope you can check for yourself and avoid making these mistakes.
The seedling time is different for different vegetables. For example, vegetables such as eggplants, peppers, and tomatoes are about 50-60 days old, while vegetables such as cucumbers, pumpkins, zucchini, and loofahs are about 40 days old. If the seedling is raised too early and cannot be transplanted when the temperature is still very low, the seedling age will be extended, making the seedling grow too tall and too large. As a result, the adaptation process after transplanting will be slow, and even lead to the phenomenon of falling flowers and fruits. Therefore, when cultivating vegetable seedlings, we must arrange the seedling time reasonably according to the local climate conditions.
When cultivating vegetable seedlings, many growers usually choose to use vegetable garden soil to prepare the seedling soil. However, it is important to note when using garden soil that different vegetable species should avoid using soil where the same vegetables are planted. For example, when growing tomato seedlings, you must not choose the soil where tomatoes have been planted before, and similarly, you should not choose the soil where cucumbers have been planted before. This is a taboo in cultivating vegetable seedlings, and it must not be ignored. Because the selection of unsuitable soil will not only affect the growth and development of seedlings, but also may cause various diseases. Therefore, it is important to pay attention to this when choosing soil for seedlings.
For growing vegetable seedlings, it is essential to control the temperature well. Before the seedlings emerge, the temperature should not be too low, and the optimal temperature range is 20-28 degrees Celsius, which helps the germination of seeds and the growth of seedlings. After the seedlings emerge, the temperature needs to be gradually reduced, generally about 5 degrees lower than before the seedlings emerge. In addition, it is important to maintain the temperature difference between day and night, which should be above 20 degrees during the day and below 15 degrees at night, and not more than 18 degrees at night. If the temperature continues to be stable during the day and night, the seedlings will continue to grow, resulting in the formation of tall seedlings. In addition, the temperature at the seedling stage should not be too low, especially in the case of continuous rainy weather, the temperature continues to be low, which will affect the flower bud differentiation of seedlings, delay flowering and fruiting, and may lead to the phenomenon of flower and fruit drop.
Whether you're growing seedlings or growing vegetables on your balcony, good ventilation and light are crucial. If there is not enough ventilation and light, the seedlings are not only susceptible to disease, but also grow too tall, too thin and too thin. The reason why many vegetable seedlings cultivated by growers and vegetables grown on balconies grow into tall seedlings is largely related to the lack of ventilation and light. Therefore, whether you are cultivating vegetable seedlings or growing vegetables on the balcony, you must maintain good ventilation and light conditions.
After the emergence of vegetable seedlings, the seedlings grow weak because the root system is just in the development stage. If the watering is too much or too frequent, the soil moisture is too high, which will lead to root rot and diseases of seedlings, the most common diseases include blight, cataplexy, etc. In addition, excessive soil moisture can lead to poor root development. Therefore, in the vegetable seedling stage, to promote the roots, to do the soil is not dry and not watered, to keep a moderate dryness, do not too much, too frequent watering.
Before transplanting seedlings, seedling refining must be carried out. This is because in the process of cultivating seedlings, due to long-term indoor or shed, seedlings will gradually adapt to the artificial environment, the leaves will often wilt, and the growth rate will also slow down, which is the so-called "dead seedlings" phenomenon. Therefore, before transplanting seedlings, it is necessary to carry out the seedling refining step in order to allow the seedlings to adapt to the external natural environment. However, when refining seedlings, it is necessary to pay attention to gradual windproof treatment, and not all of them can be released at once to prevent flashing seedlings. For example, the vegetable seedlings cultivated by the arch shed can be slightly untied at both ends of the arch shed first, and then a little larger the next day, gradually increasing the degree of air release, until the plastic sheet is completely removed, so as to complete the seedling refining process.
The above are the six taboos that need to be paid attention to when cultivating vegetable seedlings, whether it is in the seedling process of vegetable seedlings or in the process of planting vegetables, these precautions are very important. I hope that you will keep these taboos in mind and avoid making these mistakes when growing vegetable seedlings, so that you can smoothly cultivate healthy vegetable seedlings.
