【Plant Protection Technology】Sweet Cheats: A Guide to Scientific Management of Improving the Sweetness of Strawberries in November

The sweetness of strawberries is not only influenced by the variety, but also by our planting management techniques. During the critical period of strawberry ripening, taking appropriate measures can effectively improve the sweetness of strawberries, thereby improving the quality and market competitiveness of the fruit. Read this article to learn about the science of sweetening strawberries.

01 Stay well lit

○ Even on continuous cloudy days, as long as the temperature is not too low, the grass curtain should be lifted at noon to allow the plants to receive the scattered light.

○ I keep the film clean and increase the light. 

○ Lay a silver gray film or reflective curtain on the ground to enhance the light intensity between strawberry plants.

○ When conditions permit, you can install a special plant fill light for strawberries in the greenhouse.

02 Widen the temperature difference between day and night

○ During the strawberry fruiting period, the night temperature should be reduced as much as possible, and the temperature difference between day and night should be widened, and the nutrient accumulation of strawberries should be increased.

○ In case of bad weather, you should not blindly keep warm, maintain a reasonable temperature, try to widen the temperature difference, keep the temperature at 5-8 degrees at night, and keep the temperature at 18-25 degrees during the day.

03 Rational application of fertilizer

○ Control the use of nitrogen fertilizer so as not to be detrimental to the color change and sweetening of strawberries.

○ On the basis of sufficient organic fertilizer, we pay attention to the comprehensive supply of medium and trace elements. It is recommended to use one acre of Shenxi Leopard, which can supplement all kinds of medium and trace elements required for crop growth, using advanced carbon enzyme chelation technology, and there will be no antagonism between the elements, so that plants can absorb all aspects of nutrition.

○ Potassium supplementation during the fruiting period is effective in increasing the sugar content of strawberries. However, care should be taken to avoid excessive potassium fertilizer, otherwise it will affect the absorption of other nutrients (such as calcium, magnesium, etc.) by strawberries.

04 Proper control of soil moisture

○ During the strawberry harvest period, proper water control can increase the coloration and sugar content of the fruit.

○ The watering frequency can also be moderately controlled in the late maturity stage.

05 Reasonable leaf-to-fruit ratio

○ Strawberry leaf picking should be moderate, not too much, so as not to reduce the photosynthetic capacity of the plant.

○ During the flowering and fruiting period, depending on the growth of the plant and leaves, it is judged whether to remove or not, and the appropriate leaf-fruit ratio is maintained.
