A few days ago, it was rainy and snowy, and the low temperature was low, and many people reported that the strawberries are now bland and tasteless, and the taste is poor. To solve the problem of strawberries deteriorating in winter, we first need to understand how strawberries are sweetened.
Strawberries are not delicious and have a poor taste, mainly because there is less sugar in strawberries, and the less accumulation is tasteless or sour, and the more sugar accumulates, the sweeter the strawberries will be. It stands to reason that the low temperature strawberry greenhouse in winter is controlled by temperature to widen the temperature difference between day and night, and the large temperature difference is conducive to the accumulation of sugar in strawberries.
The good taste and high sweetness of strawberries are the result of the comprehensive management of a variety of factors, and a single widening of the temperature difference cannot achieve a good taste, and the accumulation of strawberry sugar is also inseparable from the management of strong leaves, suitable temperature, and sufficient supply of water and fertilizer nutrients.
1.Cloudy days with insufficient light. Continuous rainy days, short sunshine hours, insufficient light for the sugar in the plant, can not be transported normally, less sugar reflux to the fruit, poor taste. In winter strawberry management, insufficient light is a hard injury, so it is recommended to hang a fill light in the winter cloudy canopy.
2.Leaf guards. In the process of strawberry growth, a large amount of nutrients are made by the leaves, the taste and yield of the fruit are determined by the leaves, in the strawberry flowering and fruiting stage, the protection of the leaves is the key, as far as possible to retain the functional leaves, to ensure that in 8-10 pieces.
3.Temperatures are low at night. In particular, the night temperature in the fruit expansion period is 1-2, and the low temperature affects the return of leaf nutrients to the fruit, and the sugar accumulation on the fruit is less, and the fruit is naturally not sweet. The reflux temperature at night is not lower than 12, and the night temperature rises to 6-8 through warming measures, and the sugar can accumulate normally during the day in the range of 20-25.
4.Be particular about using fertilizer. Water and fertilizer nutrition is directly related to the taste of strawberries, flushing fertilizer can not always use a fertilizer, in addition to the commonly used balanced fertilizer, calcium and magnesium fertilizer with trace elements can increase the quality of the fruit, and give some potassium fertilizer appropriately during the veraison period of the expanded fruit, so that the fruit becomes more sweet.
5.Watering should not be too much during the fruit expansion period, and it is enough to see dry and wet, otherwise the taste will be dull and tasteless.
6.Take care of your roots. Do not flush fertilizer indiscriminately to avoid damaging the roots and affecting the absorption of nutrients. In the low temperature period, use a medium-temperature warm fertilizer (like deep-sea fish protein puree, rich in small molecule polypeptides and small peptides are easy to absorb). After the first strawberry fruit is harvested, the root aging is more serious, and the root aging will also affect the yield and quality of the second crop. Therefore, use the mineral source potassium fulvic acid and Bacillus subtilis** to raise the root system.
7.Variety. Varieties are very important, such as Hongyan, Sui Zhu, and Zhang Ji varieties have relatively high sugar content, and if you pursue taste, you can consider choosing varieties with high sweetness.
If you want strawberries to taste good, you need to understand that strawberries are sweetenedIf you want to grow strawberries well, comprehensive management is indispensable.
