What about the drug damage of strawberry?

Strawberry is a common fruit, in the process of planting, if the drug is not used properly, there may be a variety of drug damage. So what about strawberry drug damage?

First, what about strawberry drug damage?

1. Fertilizer supplement to promote seedlings: drug damage to the symptoms of drug spots, leaf edge scorch or yellowing on the leaf surface, appropriate amount of quick-acting nitrogen fertilizer or quick-acting compound fertilizer can also be fully sprayed to promote seedling rejuvenation.

two。 Irrigation remedy: for some drug damage caused by root irrigation and herbicide application under plastic film, appropriate watering or irrigation lotion can reduce toxicity and reduce the harmful substances accumulated in the root.

3. Spraying relieving agents: if alachlor has drug damage, gibberellin can be sprayed; 0.2% soap solution can alleviate the drug damage caused by organophosphorus pesticides.

4. Spray lotion: after spraying the wrong pesticide or drug damage, if found early, you can quickly spray clean water and wash the surface liquid. If it is caused by acidic agents, an appropriate amount of plant ash or 0.1% quicklime solution can be added when spraying water; for drug damage caused by alkaline agents, an appropriate amount of vinegar can be added when spraying water. At the same time, we should pay attention to greenhouse ventilation, cooling and humidity, which is conducive to the discharge of harmful gases.

5. Removal of damaged leaves: after drug damage, chlorotic and discolored leaves should be removed in time to curb the osmotic transmission of the drug in the plant.

Second, strawberry growth habits

Strawberry likes warm and cool climate. The growth temperature of strawberry root system is 5-30 ℃, the optimum temperature is 15-22 ℃, the optimum temperature for stem and leaf growth is 20-30 ℃, and the freezing injury of bud occurs at-15-10 ℃. The temperature during flower bud differentiation should be maintained at 5-15 ℃, and the flowering and fruiting stage should be kept at 4-40 ℃. When strawberries pass the summer, shading measures should be taken when the temperature is higher than 30 ℃ and the sunshine is strong.

Strawberry is a light-loving plant, but it has strong shade tolerance. When the light intensity is strong, the plant is short and strong, the fruit is small, the color is dark and the quality is good. Medium light, large fruit, light color, low sugar content, long harvest time; too weak light is not good for strawberry growth.

Strawberry has shallow root distribution, large transpiration and strict requirements for water, but it has different growth periods. Strawberries have slightly different requirements for moisture. In early spring and flowering, strawberries need lint percentage less than 70% of the maximum soil water holding capacity. Fruit growth and ripening period demand is more than 80%. After harvest, the stolon and new adventitious roots are extracted, and the soil water content is not less than 70%. Autumn is the period of plant nutrition accumulation and flower bud formation, and the soil moisture should not be less than 60%. Strawberries are not tolerant to waterlogging, requiring good soil permeability and paying attention to drainage in the rainy season.

Strawberries should grow in fertile, loose neutral or slightly acidic loam, too clayey soil is not suitable for cultivation, sandy soil more stable fertilizer, frequent irrigation, can also grow strawberries.
