Does the recent continuous low temperature and rainy weather in southern Jiangxi have an impact on navel orange flowers and fruits?

In the sprouting stage of spring shoots, it is rainy in early spring, cold in late spring and continuous low temperature and rainy weather. The temperature is relatively high, the growth of navel oranges is limited, and the root system is poorly developed, which seriously affects the morphological differentiation of navel oranges in the later stage of flower bud differentiation, resulting in irregular flower buds and many abnormal flowers.

During the bud white period of navel orange, it suffered from continuous rainy and low temperature weather. The weather is cold and hot, and the light is poor, which affects the formation of chlorophyll and consumes a lot of stored nutrients, thus reducing the accumulation of organic nutrients and delaying the phenology of navel orange. Due to continuous rainfall, "late spring cold" is low temperature and high humidity, which is prone to diseases, resulting in a large number of deciduous leaves and gray mold of navel orange fruit trees. Navel oranges need to protect flowers and fruits, and rainy weather is also easy to make fruit farmers lose the opportunity to play fruit protection drugs, which has a great impact on the yield of navel oranges!

Does the recent continuous low temperature and rainy weather in southern Jiangxi have an impact on navel orange flowers and fruits? Hello! I am June wind, engaged in citrus management for more than 20 years, and have accumulated some experience in citrus management and picking. Therefore, I am familiar with this problem.

Gannan navel orange is famous for its bright red and smooth color, especially in dingnan county.

Navel orange is sweet and big, and many people like it. As soon as the navel orange is picked, it is sweet and sour; But it is resistant to storage and can be put into production in May and June of the following year. In the second year, it tastes sweet and juicy without sour taste.

So, does the continuous low temperature and rainy weather have an impact on flowers and fruits? Practical experience tells you that the impact is definitely there. When oranges bloom and pollinate, if it rains continuously, it will affect pollination and then affect the fruit setting rate.

After fruit setting, some young fruits will freeze to death if they encounter continuous low temperature. Thereby affecting the output. I have found for many years that when oranges bloom, if the weather is good, the yield is high; In rainy days, the output is low.

Low temperature and low light affect pollination and fertilization, which is not conducive to fruit setting, affects the green of young fruits, and is easy to breed gray mold and epidemic rot. Immediately after cleaning, it can be sprayed with Yum Purine+Quick Bright+Liquid Boron+Peptide Bao +TPV to improve the fruit setting rate and avoid the breeding of germs.
