A course on the latest sweetening techniques of strawberries

Strawberries are bright and glossy in appearance and sweet in taste, but some strawberries look good, but they are not sweet, which gives many growers a headache. So how to improve the sweetness of strawberries? Let's take a look at the sweetening technology of strawberries with the editor.

1. Temperature and light regulation

When cultivated in the greenhouse, the temperature should be controlled at 25-28 degrees in the day and 10-12 degrees in the morning, the lowest should not be less than 8 degrees, but after entering the flowering stage, it is 23-25 degrees during the day and 8-10 degrees at night, and during the fruit expansion period, 20-25 degrees during the day and not less than 5 degrees at night, so as to regulate the temperature difference between day and night, which can accumulate sugar and improve sweetness. In addition, strawberries are cultivated in the greenhouse, the light time should not be less than 10 hours a day, if the light is not enough, electric lights or reflective film equipment can be installed to improve the lighting conditions.

2. Rational fertilization

Fertilization is also one of the ways to increase the sweetness of strawberries. Strawberries have poor plant growth and small flowers and fruits when they are lack of phosphorus, while when they are lack of potassium, they are dim in color and poor in taste, so in cultivation, appropriate application of phosphorus and potassium fertilizer can play a role in increasing production and sweetness. In addition, the application of organic fertilizer can also improve the yield and sweetness. Organic fertilizer is rich in nitrogen, calcium, magnesium, sulfur and other trace elements necessary for strawberries. At this time, chemical fertilizer is incomparable, but when using organic fertilizer, it must be completely mature.

3. Water regulation

Strawberry is inseparable from water in its growth and development. If there is too much water in cultivation, it can easily lead to excessive growth of stems and leaves and affect the yield. And when the fruit expands, if it absorbs too much water, it will dilute the internal sugar, resulting in a decrease in sweetness. Therefore, the regulation of water is extremely important, in the period of high temperature to reduce the amount of water, small water frequently irrigated, maintain soil moisture at about 60%, can significantly improve sweetness.

4. Chemical regulation

When planting, growers usually use various growth regulators to increase sweetness and yield in order to improve yield and quality. spraying vegetable and fruit Zhuangtieling during flowering and fruiting stage or fruit expansion stage can obviously improve pollen fertilization quality and strong cyclic fruit setting rate. promote fruit development and increase sweetness.
