Although the temperature is warming in the spring, the temperature is not very stable and may even turn out to be cold, so there are many issues that require attention in the spring for growing vegetables. Whether the temperature is too high or too low, it can have a significant impact on the growth of vegetables, especially in the sheds, so the necessary management points must be clear, and only scientifically sound management can lead to higher yields。
1. Prevention of human beings long
The return of temperature reduces the time available at night, when it is most likely that the phenomenon will grow, especially in the case of guacamole. The impact on yields is significant, given the fact that masters lead to flowers and fruit is prone to deformation. To prevent masters, it is important to ensure that planting is done in a timely manner and that the best planting time is not missed, and that proper management takes place within 15-30 days of planting, with attention to light, fertilizer and water. At the same time, the drains should be dug, as the spring rains are more frequent, thus facilitating drainage. If there's a growing vegetable, it has to be handled in a timely manner to control its occurrence。
Prevention of the cold
The impact of cold springs on the growth of vegetables is so great that prevention is critical if there is a freeze and there is a high risk of loss. When a seedling grows, it is required to be ventilated in a timely manner and to increase the amount of ventilation as the temperature rises, so that the seedling can exercise well at low temperatures. Prior to the onset of the winter, water should be poured, as appropriate, or sprayed on the surface of vegetables, increasing the humidity of the air and preventing freezing. If necessary, heating equipment should be used in the shed in order to improve the temperature in the shed and prevent the occurrence of freezing。
3. Anti-hormonal poisoning
As the temperature rises, the concentration of pesticides will decrease, and if it is too high, it will affect the budding of vegetables, making them susceptible to malformations of fruit, which is critical to prevent vegetable hormone poisoning and, if it occurs, to address it in a timely manner. A large amount of water was used to wash out the fluid from the surface, diluting the concentration of pesticides and using growth regulators to restore vegetables to normal growth。
4. Pest prevention
When everything recovers, pests and pests wake up, so they are prone to disease and pests when temperature rises, so that precautions are taken ahead of time. Often the preventive method of vegetables is the spraying of related drugs. If pests are detected and treated in a timely manner to control their spread. By april, the sun will have become stronger and the vegetables will be prone to sunburn and can be treated with leaf-picking measures, but not in excess of one-time graft, so that the vegetables can grow better and be effective in preventing physiological diseases。
When growing vegetables in the sheds in the spring, these concerns must be clear, and attention must be paid to every detail, which often leads to the destruction of vegetables, so that, in order to increase the production of vegetables, the growers must be in place in every detail, creating a better environment for the vegetables to grow better and to increase their production, otherwise they may face huge losses and be wasted in such good times。
