Will the recent continuous low temperature and rainy weather in southern Gansu affect the navel orange blossoms?

During the budding period of spring flower buds, we encounter harsh weather conditions such as low sunshine and rainy weather in the beginning of spring, as well as "late spring cold" low temperature and continuous rainy weather. The air temperature is relatively high, the growth of navel orange trees is restricted, and the root system is underdeveloped, seriously affecting the growth of navel orange trees. It affects the late morphological differentiation of navel orange flower buds, resulting in irregular flower buds and many deformed flowers.

During the period when the navel orange buds are white, they encounter continuous rainy and low-temperature weather. The weather is hot and cold, and the light is scarce, which affects the formation of chlorophyll and consumes a large amount of stored nutrients, thus causing the accumulation of organic matter nutrients and reducing the supply of nutrients. , causing the phenological phase of navel orange to be delayed. Due to the continuous rain, "late spring cold" low temperature and high humidity, diseases are prone to occur, and cause massive leaf loss and gray mold on navel orange fruit trees. Navel oranges need to preserve flowers and fruits, and rainy weather can easily cause fruit growers to lose the opportunity to apply fruit-preserving medicine, thus having a great impact on the yield of navel oranges!

Will the recent continuous low temperature and rainy weather in southern Gansu affect the navel orange blossoms? Hello! I am June Feng. I have been engaged in orange management for more than 20 years. I have accumulated a certain amount of experience in orange management and extraction. Therefore, my answer to your question is familiar.

Gannan navel oranges are famous for their bright red and smooth color, especially in Dingnan County.

Navel oranges are loved by many people for their sweet and large size. Once picked, navel oranges are 90% sweet and 10% sour. However, they are durable and can be stored in May or June of the following year. It tastes sweet and juicy the following year without being sour.

So, does the continuous low temperature and rainy weather have any impact on flowers and fruits? Practical experience tells you that the impact is definitely there. When oranges are blooming and pollinating, if they encounter continuous rain, pollination will be affected and the fruit setting rate will be affected.

After fruit setting, some young fruits will die from cold necrosis if they encounter continuous low temperatures. thus affecting output. I have discovered over the years that when oranges bloom, if the weather is sunny, the yield will be high; if it is rainy, the yield will be low.

Low temperature and lack of light affect pollination and fertilization, are not conducive to fruit setting, affect young fruits turning green, and are also prone to the breeding of gray mold and blight rot. After it clears up, you can immediately spray Biosine Purine + Suliang + Fluid Boron + Peptide + TPV to increase the fruit setting rate and avoid the growth of germs.
