What if strawberry stalks and petals turn red?

When it comes to strawberries, many people may be drooling silently. It can be said that strawberries are really a very attractive fruit. At present, more and more strawberries are planted in the market greenhouse, so there are many growers in consultation, when strawberry stems and petals red is what reason, is it sick? What should I do? So let Xiaobian answer this question for everyone today.

1. The cause of strawberry stem redness

If strawberries have red stems, there are many reasons for that. First of all, it may be due to the low winter temperature and low phosphorus absorption rate, which leads to the inability of nutrients in strawberry leaves to be transported, resulting in anthocyanins and red stems. Secondly, with the growth of strawberry planting years, the relatively aged stems and leaves will also appear red phenomenon, which is a normal natural weakness phenomenon. In addition, in the process of planting, watering and fertilization and field management such as loosening soil are not handled in place, which will also cause strawberry stems to turn red. Finally, timely planting conditions are not suitable, such as too high or too low planting temperature, too high or too low humidity, poor soil permeability, poor drainage, etc., which will affect the normal growth of strawberries and cause stem redness.

2. The cause of strawberry petals redness

Strawberry petal redness is mainly caused by two reasons, the first reason is that strawberry flowering coincides with low temperature weather, and under this condition, anthocyanin content will increase, then we see petals will appear red, sometimes even purple red, if there is no timely temperature control, then there may be leaf shrinkage and death phenomenon. The second reason is powdery mildew and gray mold precursor, when the field humidity is too high, then this will also cause strawberry petals red, and also affect the growth of young fruit. If the disease worsens, it will seriously affect the yield and quality of strawberries and make them lose their economic value.

3. Prevention and control methods

Although the early stage of strawberry stem and petal redness has little effect on strawberry itself, if it is not controlled in time, the loss to growers is very large. Generally, when this phenomenon occurs in strawberry orchards, we need to strengthen field management and make reasonable adjustments to temperature, humidity and permeability. When necessary, you can use Liangguo An to spray on the right amount of Diwang and Wofengsu. There is also the need to prevent gray mold and powdery mildew when the petals turn red at flowering stage, so it is necessary to use the right amount of garlic oil to control it.

If strawberries appear red stems or red petals in the process of growth, then we first need to comprehensively analyze according to the seasonal time, the location of the occurrence and the cause of the occurrence, so as to effectively prevent the occurrence of diseases and play a timely role in stopping losses.
