Blueberry stands for the only one, and: the homophonic word of Alps is love you, and the original flavor stands for classic love. The meaning of blueberries is still very beautiful. Generally, if boys send blueberries to girls, it implies that love is sour and sweet. It means that they want to be together forever, live a sour and sweet life and never give up.
It is a perennial shrub of Vaccinium of Ericaceae. Its leaves are alternate, with serrated and oval edges. Racemes have 7- 10 flowers, which usually bloom in spring with white or pink petals. Most fruits are dark blue or purple, and a few are red.
Blueberry is a very auspicious tree species, which symbolizes unswerving love and eternal love in geomantic omen. It is an auspicious plant, which can prosper the relationship between husband and wife. But we'd better not grow blueberries indoors, otherwise it will affect its normal growth. For blueberry trees, it is suitable to grow in sunny environment, but the indoor lighting environment is worse than outdoor. Therefore, it is easy for blueberry trees to grow white at home, and it is not recommended to grow blueberries at home.
Blueberry plants are large, and their branches will grow and disperse, so there must be enough space when planting. So when planting blueberries, it is not recommended to plant them at home. On the contrary, it is more suitable for planting in outdoor open places.
Growth habit of blueberry:
Blueberries can grow many times in a growing season, and secondary growth is more common. In southern China, blueberries have two growth peaks in a year, the first is from May to June, and the second is from mid-July to mid-August. In the third year after planting, the growth of seedlings was obviously accelerated, and the new branches germinated and grew vigorously, and the annual growth could reach more than 1 m.
In those years, flower buds were mostly formed at the top of branches and differentiated from top to bottom. The number of differentiated flower buds per branch is related to the variety and branch thickness. Generally, there are 4-7 high cluster blueberries and 3-6 rabbit eye blueberries, and the flower buds are mainly solitary in the node. The flower bud differentiation period of various blueberries is different. Dwarf blueberry and tall blueberry began to differentiate from July to August, and rabbit-eye blueberry began to differentiate from mid-June. By the end of September to the beginning of 10, the flower bud differentiation of blueberry had been completed.
From the morphological point of view, blueberry flower buds are hypertrophy, oval or nearly spherical. Below the flower buds are some narrow-pointed vegetative buds and dormant buds.
The flowering period of blueberry is obviously different due to the different climate and varieties. The southern part of China blooms in early and middle March, and the northern part blooms in April-May. The flowering period is usually 15-20 days, and the longest is 40 days. Flowers are planted on slender shafts to form racemes.
At the same time as the flowers bloom, the vegetative buds begin to develop into vegetative branches. Vegetative branches stop growing when they grow to a certain extent (different lengths). The last thin-pointed young leaf at the top turned black and turned into a black tip, and the "black tip" fell off after about 2 weeks. After 2-4 weeks, the vegetative buds under the black tip grow new branches, which has the advantage of the top, that is, the rotation axis of branches grows 3-5 times a year in the south.
In summer, the bud primordium next to the "black spot" on the last new shoot gradually expands and develops into a flower bud, occupying the top position. The flower buds at the top of the branches can form several flower buds, which will blossom and bear fruit in the next spring. The vegetative buds under it develop into vegetative branches, and the short branches that bear fruit gradually dry up and fall off after autumn.
