When will loquat blossom?

Generally speaking, loquat usually blooms after June 10 every year, and the flowering period can be in June 10 the following year. From the first flower to the whole tree and then to the last flower, the whole flowering period takes about 2 to 4 months. The flowering period can be distinguished according to climate, tree potential, varieties and branches. For example, where the temperature is warm, flowers generally bloom earlier.

The flowering period of loquat can be divided into head flower, second flower and third flower. Generally speaking, the head flower is rich in nutrition, the young fruit has a long development time, the fruit is large and the quality is good. However, due to the high temperature and medium-low temperature at flowering stage, the development will be imperfect, the pollination rate will be low, and it will be vulnerable to freezing injury. However, the second flower has more flowers and more fruits, the fruit quality is second only to the first flower, and the freezing damage can be slightly less than the first flower. Three flowers are late, the development period of young fruit is short, and the fruit quality is poor, but there is no freeze injury. In addition, the buds of loquat will not open at low temperature, but will bloom as soon as the weather gets warmer. In addition, loquat also has the characteristics of many flowers and long flowering period.

Therefore, from this feature of loquat flowering, it is the most vulnerable to freezing injury. Generally speaking, if loquat blooms from June 5438 to 10 every year, such flowers are called early flowers. Although there is nothing to bloom at this time, the flowering period of loquat is very long. Once opened, it will face a cold winter and may not be able to survive the winter. Therefore, in addition to freezing injury, in low temperature rain and snow weather, fruit can not be set because of imperfect division and poor pollination. In this way, the fruit setting rate at the initial flowering stage is particularly low, and the early flowering phenomenon of loquat should be avoided in the cultivation of loquat.

Some people may say, is it not good for loquat not to bloom early and spend late? Because the flowers that bloom late can avoid the cold winter, it is good to welcome the warm spring as soon as they bloom. In fact, the flower temperature of loquat is too high or too low, because the pollen of loquat begins to germinate above 10℃, and about 20℃ is the most suitable. When the temperature is lower than 5℃ and higher than 35℃, the pollen germination rate is particularly low, that is to say, the pollination rate is high only at a suitable temperature, thus improving the fruit setting rate. If it is too late, it will often lead to stunting and malnutrition, resulting in low fruit setting rate.

But in reality, the phenomenon of early flowering is generally much later than that of flowering. Why is it formed? The fruiting branches of loquat are mainly mature fruiting mother branches, which are produced by mixed buds at the top of spring shoots and summer shoots, and the inflorescence is developed from fixed buds of fruiting branches. After high temperature or cooling, the peak begins to form. But generally speaking, in early spring, after spring shoots germinate in June 5438+10-February, summer shoots germinate in April-May. When hot and dry weather comes in May and June, summer buds are forced to bloom in June and August. In addition, in spring, summer buds can only germinate when fertilizer and water are sufficient. If you can't ensure rich water, especially water, you will be forced to bloom and form early flowers in the spring shoots.

Generally speaking, although loquat is a drought-tolerant variety, especially the bud is more drought-tolerant than the tree, if the bud blooms too early, blooms during the low temperature in winter and bears fruit in spring, it will be easily affected by low temperature.
