Vegetable hormone poisoning

Good plant structure is the premise of rich harvest of vegetables. Therefore, since the seedlings are planted, the farmers should pay attention to the adjustment of plant growth, even in the cold winter, the work can not be relaxed. In the early stage of vegetable growth, in the case of good heat preservation and sufficient fertilizer and water, there will still be a strong growth situation, which will adversely affect the subsequent flower bud differentiation and fruit development. When farmers are in control, in order to pursue rapid effects, they often choose to spray chemical control agents. Once the dosage or the timing of spraying is not good, hormone poisoning is likely to occur. At the same time, the concentration of anthers is too large or frequently used, and the fertilizer contains factors such as growth-promoting hormone, which may also cause hormone poisoning in plants.

In the low temperature season, the metabolism of vegetables is slow. How to quickly return to normal growth in a short time? In this regard, Xiao Bian recommended vegetable farmers, multiple mitigation measures at the same time.

Spray relief agent

Generally, when the concentration of chlormequat is too high, the growth of the plant is slow, the color of the growing leaves is dark green, the internodes are short, the stems are thick and strong, and when the amount of 2,4-D is too large, it will be in the plant. Accumulation, a certain part of the plant or growth point, the leaves are curly and slender, the color is yellow, and the relief can be carried out with the relief agent.

Warming up

Entering the deep winter, the weather is low and the temperature is low, which will affect the growth of the plant. If the measures are not taken in time, it will be difficult for the plant to recover. The growth temperature of the plant in the fruiting period is 25-30 °C during the day and 15-20 °C during the night. In order to improve the growth of the plant, we must pay attention to the adjustment of the night temperature. The main measures that can be taken are:

The first is to control the time to close the vents. If the vent is closed too late, the temperature in the shed will be lower when the curtain is placed, which will affect the night temperature.

The second is to increase the night temperature by setting up a shed in the shed. The “shed shed” is a multi-layer cover. Its function is to use the non-flowing air layer formed between the two layers of film to reduce the convective exchange of heat in the air and reduce the loss of heat, so that the temperature of the night shed is slowed down.

Regulating fertilizer management

In order to increase plant growth, we should increase fertilizer management. However, the temperature in the deep winter season is low. If you increase the amount of watering blindly, it is easy to cause damage to the roots. Therefore, in the process of watering, it is necessary to follow the principle of a small number of times. At the same time, some high-nitrogen water-soluble fertilizers and fertilizers such as chitin and rooting agent can be applied with water to increase the growth of the plants.
