The survival rate of the latest strawberry planting is not high? How to prevent and cure effectively

Strawberry cultivation generally uses the method of seedling transplanting, but in late August, it is the strawberry planting period, the planting quality has a great impact on the growth and management of strawberry. But many growers often have the problem that the survival rate of strawberry planting is not high, so how to prevent it? Let's get to know it.

1. Insufficient or excessive base fertilizer

Strawberries apply excessive organic fertilizer, compound fertilizer or immature organic fertilizer before planting, which will lead to the burning of seedlings after planting and gradually lead to the death of strawberries. Therefore, the application rate of base fertilizer before planting is more critical. Farm manure and organic matter must be applied after full maturity. In general, the amount of organic fertilizer applied per mu is about 3000 kg, spread evenly on the surface, and then turn over deeply and then rotary tillage. If the seedling burning phenomenon occurs, it is necessary to increase the amount of water, on the one hand, in order to reduce the ground temperature, on the other hand, in order to make excess nutrients deposition and improve the soil environment.

2. Planting depth

Strawberry is a shallow root crop, its main distribution in the soil layer of about 20 cm, planting to remove old leaves and necrotic roots of strawberry seedlings as flat as the soil surface. Strawberry planting too deep, will lead to immersion, affect the extension of new leaves, poor permeability, will lead to seedling death, planting is too shallow, rhizome exposed to the surface, should not produce new roots, new stems are exposed to the sun, easy to cause seedling drying and death. For the seedlings that are too deep, we can lift the seedlings lightly, but we must pay attention to the control efforts to avoid root fracture, so as to reduce the survival rate. At the same time, spray or irrigate with Qingku Like 150-300 times + Tilwang 300-500 times to avoid root rot. In addition, it is necessary to supplement nutrients, rejuvenate the plant body, which is conducive to slow seedling, but also through soil adjustment, improve soil structure and increase permeability.

3. Excessive amount of water

Strawberry is neither drought-resistant nor waterlogging-resistant. Its root system has weak water absorption capacity and is sensitive to water. In general, it only needs to maintain about 60% of the soil water holding capacity. It should be irrigated immediately on the day of planting, and pay attention to the amount of water in the slow seedling stage, too much water is not conducive to root growth, but also cause retting roots.

4. Do not tidy up the plant before the slow seedling ends.

The slow seedling stage is when the new root is just growing, and the root system is weak, so the finishing plant is easy to hurt the root system, thus affecting the seedling growth. At the same time, the wound caused by finishing is easy to cause pathogen and insect pest infection, thus reducing the plant growth. If you find a diseased leaf, you can use scissors to cut it from petiole 2 to 3, and you can't split the leaf directly. And use spray Chinese herbal medicine to repair the wound and kill the pathogen.
