Causes and solutions of strawberry leaf desiccation

In the process of strawberry plants, it is a common phenomenon that leaves are dry and lose normal photosynthesis, and normal plants accumulate less nutrients, which is not conducive to the improvement of yield and quality. So what is the cause of the dry strawberry leaves? Let's get to know it with the editor.

1. Fertilizer damage

One of the main causes of strawberry leaves drying up during fertilizer damage, and this phenomenon is very common, one of the causes of fertilizer damage is that farmers do not grasp the amount of fertilizer, one-time excessive fertilization; another reason is to save trouble, a variety of fertilizers are mixed together to increase the concentration of fertilizer; the third is that the fertilizer is not mature organic fertilizer.

Solution: in view of the causes of fertilizer damage, take targeted prevention and control measures, the application of fertilizer should be used in strict accordance with the usage of fertilizer packaging instructions, it is best not to increase the concentration without authorization; do not mix many kinds of fertilizers together, it is recommended to build the use of each kind of fertilizer and increase water consumption when needed. The application of base fertilizer must choose completely mature organic fertilizer, which can be irrigated with heavy water and dilute the concentration of fertilizer solution after fertilizer damage, which can play a mitigation role.

2. Calcium deficiency

Calcium deficiency is also one of the reasons for the dryness of strawberry leaves, which is characterized by foliage, wrinkles, light green or yellowish boundaries, chlorotic leaves, brown spots on the petioles of diseased leaves, and often syrup-like water overflow.

Solution: strawberry calcium deficiency can quickly relieve symptoms by foliar spraying chelated calcium, and alkaline soil can also block the absorption of calcium by roots and adjust soil pH properly. In addition, organic fertilizer and microbial agents were added to regulate soil permeability and improve soil structure.

3. Retting root

After heavy rain, the field water, strawberry roots soaked in water for a long time, root respiration is blocked, a long time to produce alcohol will poison the roots, resulting in root damage. After the root system is damaged, the absorption of nutrients and water will be blocked, resulting in short plants, yellowing leaves, drying up, and serious death of seedlings.

Solution: low seedling cultivation should choose land with good drainage and irrigation, sowing ditches are smooth, especially after rain, stagnant water should be removed in time, and planting should be cleaned up at the same time to clean up the mud around the seedling center and rhizome.

4. Drug damage

Weeding in the seedling stage can easily lead to drug damage to seedlings, strawberries are more sensitive to pesticides, some pesticides will lead to leaf yellowing, and some pesticides may even cause seedling death. There are two main reasons for the drug damage, one is that the concentration of the drug is too high, and the other is the use of strawberry sensitive agents.

Solution: herbicides must be used in accordance with the packaging instructions, and it is best not to mix herbicides. For reasons of herbicides, try to choose herbicides that have been used on strawberries with little or no harm, and those that have not been used should be tried out first. In the promotion of large-scale use. After the occurrence of drug damage, stagnant water can be sprayed with clear water environment, gibberellin and brassinolide can also be sprayed to alleviate, but also pay attention to the concentration.

The above is the introduction of the causes and solutions of strawberry leaf dryness. I hope it can help you. If you want to know more about it, please follow us.
