Increasing the photosynthesis and respiration of strawberry plants with day and night temperature differences are affected by temperature. When other conditions are appropriate, the higher the temperature, the stronger the effect. During this time, the temperature in the greenhouse during the day is maintained at 16 ° C to 18 ° C, and at night it is more suitable between 6 ° C and 8 ° C. The general temperature difference does not exceed 10 ° C. In this way, when the temperature difference between day and night is large, the strawberry accumulates a large amount of organic matter during the day, consumes less nutrients at night, accumulates more organic matter, and has a higher sweetness. After applying the foliar fertilizer to the flowering fruit stage, the root consumption of the root system is relatively large, and it is prone to insufficient stamina. At this stage, attention should be paid to rooting and rooting, and timely application of water-soluble fertilizers to promote root growth. In production, the lack of phosphorus and potassium in strawberries is more common. In the absence of phosphorus, the plant grows poorly, and the leaves, flowers and fruits become smaller; the potassium deficiency is light in color and poor in taste. Therefore, the timely and appropriate application of phosphorus and potassium fertilizer, control of nitrogen fertilizer, can play a significant role in increasing production. At the same time, it is possible to spray two to two thousandths of phosphorus and potassium fertilizer on the outer leaf surface, which is helpful for the accumulation of sugar content of the fruit. Water management During the fruit expansion period, because there is more demand for water, it is better to keep more water and keep the relative humidity of the soil at 80%. The fruit ripening period should pay attention to water control, watering principle to meet the water demand of strawberry. It is advisable to control the relative humidity of the soil to about 70%. In the harvesting time, try to complete the fruit harvesting before 9:00 am, so as to maintain the sugar in the fruit and extend the storage period.
