What to Do When Strawberry Transplanting Survival Rate Is Low? A Detailed Guide to Effective Control Methods

Strawberry cultivation generally uses the seedling transplanting method, and late August marks the strawberry transplanting period. The quality of transplanting has an enormous impact on strawberry growth and management. However, many growers often encounter the problem of a low strawberry transplanting survival rate. So how should it be prevented and controlled? Let's find out together.

1. Insufficient or excessive base fertilizer

If excessive organic fertilizer or compound fertilizer is applied before strawberry transplanting, or if undecomposed organic fertilizer is used, it will cause seedling burn after transplanting, gradually leading to strawberry plant death. Therefore, the amount of base fertilizer applied before planting is quite critical. Farmyard manure and organic matter must be fully decomposed before application. Under normal circumstances, about 3000 kg of organic fertilizer is applied per mu, spread evenly on the soil surface, then deep plowed and rotary tilled. If seedling burn occurs, the irrigation amount needs to be increased: on one hand to lower the soil temperature, and on the other hand to settle excess nutrients and improve the soil environment.

2. Transplanting depth

Strawberry is a shallow-rooted crop, with its main root group distributed within about 20 cm of the soil layer. When transplanting, old leaves and necrotic roots should be removed, and the crown of the strawberry seedling should be level with the soil surface. Transplanting too deep will cause the crown to be buried, affecting the extension of new leaves; poor aeration will lead to seedling death. Planting too shallow leaves the root crown exposed above the soil surface, making it difficult to produce new roots; the new stem is exposed to the sun, which easily causes the seedling to dry up and die. For seedlings planted too deep, the seedlings can be gently lifted, but be sure to control the force to avoid breaking the root system, which would reduce the survival rate. At the same time, use Qingku Like at 150-300 times dilution + Diliwang at 300-500 times dilution for spraying or root drenching to prevent root rot. In addition, supplement nutrients to rejuvenate the plant body and help it recover from transplanting. Soil conditioning can also be used to improve soil structure and increase aeration.

3. Excessive water

Strawberries are neither drought-resistant nor waterlogging-resistant. Their root system has a weak water-absorbing capacity and is quite sensitive to moisture. Under normal circumstances, it is only necessary to maintain about 60% soil water-holding capacity. On the day of transplanting, irrigation should be done immediately. During the recovery period, attention should also be paid to the irrigation amount; too much water is not conducive to root growth and can also cause root rot.

4. Before the recovery period ends, do not tidy the plants

During the recovery period, new roots have just emerged and the root system is weak. Tidying the plants easily damages the roots, thereby affecting seedling growth. At the same time, wounds created by tidying are prone to infection by pathogens and pests, thereby reducing plant vigor. If diseased leaves are found, they can be cut off with scissors at 2/3 of the petiole; the leaves must not be torn off directly. Spray Chinese herbal medicine to repair the wounds and kill pathogenic bacteria.
