Raisin Branch Causes and Treatment Methods
A small knowledge of life, introducing the raisin branch causes and treatment methods of flowering knowledge, specific introduction is as follows:
Raisin Branch Causes and Treatment Methods
Raisin branch withered leaves can be divided into physiological and pathological according to their causes of onset. They may be caused by heat damage, potassium deficiency, magnesium deficiency, withering, or improper maintenance. The main treatment methods for physiological withered leaves include reasonable water supply, cooling and shading, spraying Seapower biological stimulant foliar type, supplementing medium and trace elements, and timely topdressing to improve the soil environment and promote root growth.
What Happens to Raisin Branches
Raisin branches appear more often in summer. Due to the numerous and difficult-to-distinguish causes of grape withered leaves, if prevention and treatment are not timely or appropriate, it can lead to premature leaf shedding, affecting fruit quality, and in severe cases, even tree death and garden destruction.
Raisin Branch Causes
Raisin branch withered leaves can be divided into physiological and pathological according to their causes of onset.
1. Physiological withered leaves often occur in small areas, are not infectious, and are closely related to environmental conditions or agricultural operations. They may be caused by high temperatures after rain or by sunlight dripping from greenhouse film, or by potassium or magnesium deficiency.
2. Pathological withered leaves have an onset center and are infectious. They are often caused by improper watering, fertilization, poor ventilation, or too much sunlight, leading to many diseases such as downy mildew, white rot, and T-J disease, all of which can cause branch withering.
Raisin Branch Treatment Methods
After the phenomenon of grape branch withering and leaf drying occurs, if the underground roots are not dead, they can still survive with proper care.
1. After grape branch withering and leaf drying, an initial judgment should be made to first determine whether it is caused by physiological reasons or diseases.
2. The main treatment methods for physiological withered leaves include reasonable water supply, cooling and shading, spraying Seapower biological stimulant foliar type, and supplementing calcium, magnesium, boron, and other medium and trace elements to enhance leaf photosynthetic efficiency and resistance to high temperatures.
3. For simple deficiency withered leaves, topdressing can be carried out from the expansion stage of young grape fruits to the color change stage. However, if the root problems are caused by fertilizer damage, waterlogging, or soil issues, careful maintenance is needed, applying Seapower biological stimulant root application type to promote root recovery and improve the soil environment, fundamentally solving the problem.
4. Pruning: The withered branches of grapes need to be pruned, usually after the grape bleeding period, often in early June in the northern regions. This can be done together with the removal of new shoot tips. Pruning withered and bad branches can reduce nutrient and water consumption, enhance ventilation and light transmission, and reduce diseases and pests. For withered leaves caused by diseases, appropriate medications should be applied, pruning diseased leaves and fruits.
