Let's talk about the small experience of plant cultivation on why it is better not to water grapes after they germinate. Next, the editor will introduce to you.
Why it is better not to water grapes after they germinate
After the grapes have germinated, it is better not to water them. Watering at this time will lower the ground temperature too much, affecting the growth of the tender shoots that have already started to grow, affecting the differentiation of flower buds, and not conducive to high-yield grape production.
In some places, to protect the grapes from damage during the winter, the vines are covered with soil for insulation. After the temperature rises in spring, the soil is then removed and the vines are put back on the trellises. A few days later, before germination, water thoroughly once, which is also known as the germination-inducing water. Amino acid water-soluble fertilizer can be applied with the water at a rate of about 5 kilograms per mu. It is not advisable to water too frequently to prevent lowering the ground temperature, which is not conducive to grape growth.
Watering should be done in the middle of a sunny day to help reduce the drop in ground temperature. Pay attention to the weather forecast and do not water when a cold wave arrives. Watering should be done in advance. After the grapes have germinated, it is better not to water them. Watering at this time will lower the ground temperature too much, affecting the growth of the tender shoots that have already started to grow, affecting the differentiation of flower buds, and not conducive to high-yield grape production.
It is important to pay attention to whether the phenological period of the grapes and the weather conditions are suitable for watering. From the flowing of the grapevine sap, germination, to before flowering, it is 30-40 days. This is the season of spring drought, and the grapes are in urgent need of a large amount of water for germination, shooting, leaf expansion, and the continued differentiation and growth of the inflorescence. However, it is not advisable to water too much to avoid affecting the rise in ground temperature.
Watering after germination should be accompanied by fertilization, and attention should still be paid to the ground temperature. It should not be too dry before watering, as it may cause the stems to crack and the wounds may become infected; nor should it be watered too frequently, as the ground temperature recovers slowly and the grapes do not grow well.
