Embodiment

[0031] (1) Blueberry planting and management

[0032] The blueberry variety "Legacy" (Legacy), which is more than 3 years old, has full flower buds and a large number, is selected as the plant material, and peat, organic fertilizer, and river sand are mixed into a cultivation substrate according to the volume ratio of 4:1:0.8. Flower pots with a height of 28 cm are used as containers, and the substrate is potted, the seedlings are planted, and watered once. Place the planted blueberry seedlings in a sunny place indoors, keep the day and night temperature at 14-20°C, and manage by closing the windows at night and opening them during the day.

[0033] (2) Color change management

[0034] After the blueberries go through the phenological stages of flower bud expansion, cracking, and inflorescence elongation, move them outdoors when the white flower buds are exposed by 3mm, and keep the cultivation temperature at 10-20°C during the day and 4-9°C at night , keep for 2 days, blueb...

Abstract

The invention discloses a method for changing the flower color of blueberries cultivated in containers. Blueberry seedlings that are more than 3 years old and full of flower buds are selected, planted in containers, and managed indoors under conventional conditions; when the white flower buds of the blueberries are exposed to 3 mm , move the blueberries outdoors, adjust the cultivation temperature to be controlled between 10-20°C during the day, and between 4-9°C at night, and keep for more than 2 days until the blueberry flower color changes to red; move the blueberry that has changed flower color to Indoors, continue to manage according to conventional conditions. The method of the invention is simple, satisfies the needs of the public, can change the blueberry flower color from white flower to red flower within 5 days, and can maintain the red color for a long time. By adopting the method, the variety of blueberry flower colors is increased, and the ornamental value of the blueberry is improved.

Description

technical field [0001] The invention relates to a method for changing the color of blueberries in container cultivation, and belongs to the technical field of fruit tree cultivation. Background technique [0002] Blueberry (Vaccinum ssp.) is an important fruit tree economic crop. Its fruit is rich in anthocyanins and other beneficial ingredients for human health. It can be used as fresh fruit, juice, dried fruit, pastry filling, etc. In addition, the blueberry has a beautiful flower posture, the corolla is in the shape of an altar or a lantern, and the branches hang down when it is in full bloom. The flower color is pure white or pink, the appearance is small and beautiful, and it has a high ornamental value. However, at present, people have insufficient research on the technology of its flower color regulation, and the ability to change flower color is very limited. Therefore, reducing the ornamental value of blueberry flower color has become an important limitation in blue...
