Plum blossoms are in full bloom in Xixi National Wetland Park. Will it matter if cold air strikes?

It won't affect. Plum blossoms are cold and have the characteristics of staying in winter and not dying. They are not afraid of cold and can grow normally in cold weather in winter. Plum blossoms are in full bloom in the cold winter, and can tolerate the low temperature of minus 60 degrees.

Morphological characteristics of plum blossom plum blossom is a small tree and sparse shrub with a height of 4- 10 m; Bark light gray or greenish, smooth; Branchlets are green, smooth and hairless. Leaf blade is ovoid or ovoid, 4-8 cm long and 2.5-5 cm wide, with tip and tail tip, wide wedge-shaped to round base, leaf margin with small sharp serrations, grayish green, pubescent on both sides when young, gradually falling off when growing, or pubescent only between inferior veins; Petiole length 1-2 cm, hairy when young, shedding when old, often with glands.

Flowers solitary or sometimes two peanuts in 1 bud, 2-2.5 cm in diameter, with strong fragrance, opening first and then leaves; Pedicel is short, about 65438 0-3 mm long, often glabrous; Calyx is usually reddish brown, but some varieties of calyx are green or green purple; Calyx tube broadly campanulate, glabrous or sometimes pubescent; Sepals ovate or suborbicular, apex obtuse; Petals obovate, white to pink; Stamens short or slightly longer than petals; Ovary densely pilose, style short or slightly longer than stamens.

The fruit is nearly spherical, 2-3 cm in diameter, yellow or greenish white, pilose and sour; Mucosal nucleus; The nucleus is oval, with a round top and a small protruding tip, the base gradually narrows into a wedge shape, the two sides are slightly flat, the abdominal edge is slightly blunt, there are obvious longitudinal grooves on the ventral and dorsal sides, and there are honeycomb holes on the surface. The flowering period is winter and spring, and the fruiting period is May-June (the fruiting period in North China is extended to July-August).

According to the ecological habits of plum blossom, the high dry land with loose soil, good drainage and sunny ventilation is also selected for open planting. After survival, it is generally unnecessary to water when the weather is not dry. Apply fertilizer three times a year and base fertilizer in winter to improve the ability of wintering and cold protection and prepare enough nutrients for growth in the coming year. Apply quick-acting flower-accelerating fertilizer before flowering, and apply quick-acting flower bud fertilizer after new shoots stop growing to promote flower bud differentiation. Every fertilization should be combined with watering. Appropriate measures should be taken to prevent cold in winter in the north. When planting on the ground, special attention should be paid to pruning and shaping. Reasonable pruning is beneficial to control plant type, improve the light condition in crown and promote the early flowering of young trees. Pruning is mainly based on thinning, and it is best to make it beautiful and natural. When pruning, it is advisable to cut off the branches a little. Overweight can easily lead to excessive growth, which will affect the next year's flowering. Prune more dead branches, diseased branches and long branches than in early winter, and trim and shape the whole plant properly after flowering. In addition, management should be strengthened at ordinary times, and attention should be paid to intertillage, irrigation, weeding and insect prevention.
