How to prevent premature senescence of strawberries

In recent years, due to the considerable economic value of strawberries, the planting scale of strawberries in greenhouse is also expanding, but there are many problems in the process of planting. As we all know, strawberry is a perennial herbaceous fruit. If premature senescence occurs, it will have a great impact on the yield of strawberry. So what are the symptoms of premature senility in strawberries? Why is there premature senility? Is there any solution? Let's learn about it together.

1. Symptoms of premature senility of strawberries.

Many people say that strawberries appear premature senescence in the process of growing, so what kind of phenomenon indicates strawberry premature senescence? In the normal growth process of strawberry, the branches and leaves are exuberant, the leaves are green and shiny, the flowers are many, the fruits are many, and the fruit quality is high. But when the strawberry plant appears premature senescence, we can obviously see the changes of the plant. The leaves of the plant appear yellow, the leaves are thin, the whole plant looks lifeless, there is no luster on the surface, few flowers, less fruit, small fruit, and so on. When these symptoms appear, it is generally the premature senescence of strawberry plants.

2. Why strawberries appear premature senescence

The premature senility of strawberries can be divided into two types from a professional point of view. The first is physiological premature senility, such as the problems of strawberry varieties, malnutrition caused by improper fertilization, improper use of hormones, improper use of drugs, lack of supplementation of trace elements, poor permeability, improper humidity management, excessive growth of branches and leaves, and so on. The second is pathological premature senility, which mainly refers to the impact of diseases and insect pests on strawberry plants, which leads to the phenomenon of strawberry plant wilting and premature senescence.

3. How to prevent premature senescence of strawberries

In order to ensure the production of strawberries, we must make preparations in advance to prevent the premature senescence of strawberries. First of all, we can prevent it by selecting high-quality strawberry varieties; secondly, we can strengthen the water and fertilizer management of strawberries to ensure the adequate supply of nutrients, replenish nutrients and water in time, and spray foliar fertilizer reasonably. according to the characteristics of strawberry water demand, watering every five to ten days; strengthen plant adjustment, timely removal of old leaves, leaves of diseases and insect pests, residual fruits, dense fruits, etc., to reduce the loss of nutrients. Timely removal of mature fruits, thinning of some buds and small fruits, weak fruits, deformed fruits, etc.; strengthen temperature management, reasonably adjust the temperature difference between day and night, and properly adjust the time of ventilation; finally, do a good job in the prevention and control of diseases and insect pests, the most important of which are powdery mildew, gray mold and the harm of aphids, thrips and red spiders.

The above is the whole content of preventing premature senility of strawberries. In the above, the editor briefly introduces the symptoms, causes and prevention methods of premature senility of strawberries, hoping to help you. We need to pay more attention to the later planting process, because the improvement of output and quality can improve the income of strawberries.
