Maintenance and management methods of Prunus mume

The elm leaf plum gets its name because its leaves look like elm leaves. The leaves of the elm leaf plum are like elm trees and its flowers are like plum blossoms, so it is named "elm leaf plum". With dense branches and leaves and colorful flowers, Prunus mandshurica is an important green flowering shrub species in gardens, streets, roadsides and other important trees in northern China. If you want the elm-leaf plum to blossom and flourish in early spring, you must do a good job in the maintenance of each period, so let's popularize the conservation methods of the four seasons for everyone today.

[spring maintenance method]

Spring is the peak season for the growth of elm-leaf plum, so it is necessary to give it sufficient sunshine and put it in places with bright light as far as possible, such as well-lit living room, bedroom, study and so on.

After indoor maintenance for a period of time (about a month or so), it should be moved to an outdoor shaded place to maintain for a period of time, so alternate maintenance.

In spring, we should also pay attention to watering green water at the beginning of March, pouring enough water thoroughly, and watering it again in late April.

After the flowering period of elm leaf plum in spring, a lot of nutrients are consumed, so topdressing should be carried out.

[summer maintenance methods]

The elm leaf plum likes the warm climate, but the hot and muggy environment in summer is not conducive to its growth, so it is necessary to keep the ambient temperature below 35 ℃ and the air relative humidity below 80%. It is best to keep it at 50% and 70%.

[autumn maintenance method]

Autumn is also the peak season for the growth of elm-leaf plum, in addition to changing the conservation environment like spring, but also for water and fertilizer management.

Water and fertilizer management should be carried out in the order of fertilizer-clear water-fertilizer-clear water, with an interval of about 1m / m 4 days, with shorter intervals in sunny days or high temperatures, longer intervals in rainy days or low temperatures, or no watering.

[winter maintenance method]

The growth of Prunus mandshurica is very strict to the temperature in winter. When the ambient temperature is below 10 degrees Celsius, it will stop growing and can not survive the winter safely under frost.

The dormant period of Prunus mandshurica in winter is mainly to control fertilizer and water. Fertilizer and water management cycle is in the order of fertilizer-clear water-clear water-fertilizer-clear water-clear water. The interval period is about 3 min 7 days. The interval period is shorter in sunny or high temperature days, and longer or not irrigated in rainy days or low temperature days.

[key points of culture]

1. Soil: the requirement of soil is not strict, but it is not resistant to waterlogging and prefers neutral to slightly alkaline, fertile and loose sandy loam.

2. Sunshine: sufficient sunshine can be given in autumn, winter and spring. When maintaining indoors, try to put it in places with bright light, such as well-lit living room, study, balcony and so on.

3. Temperature: like the warm climate, but the hot and muggy environment in summer is not conducive to its growth; the temperature in winter is very strict, when the ambient temperature stops growing below 10 ℃, it can not survive the winter safely under frost.

4, watering: avoid waterlogging, planting in spring, if the weather is dry, water 2-3 times, usually no watering, at the same time, pay attention to rainy season drainage.

5. Yuyemei likes fertilizer, and several shovels of rotten cattle and horse manure can be used as base fertilizer when planting. After entering the normal management in the second year, it can lag behind in spring every year, and apply fertilizer once before winter during the period of flower bud differentiation in summer.

6. Pruning: pay attention to pruning branches in the process of growth. After the flower fade, cut the flower branches moderately, leaving 3-5 buds on each strong branch. After falling in, prune again, and top and pick the heart, so that the nutrients are concentrated and the flower buds germinate.

7. Diseases and insect pests: the main diseases and insect pests of Prunus mandshurica are brown spot, white feather, aphids, stinging moths, red spiders, leaf rollers and so on, which generally occur in summer and autumn, so they should be sprayed and controlled in time.

Experts suggest that for the conservation of Prunus mandshurica, we should not only do a good job in water and fertilizer management, but more importantly, do a good job in the prevention and control of diseases and insect pests, and for some trees that die suddenly, we must find the causes and take targeted prevention and control measures. In peacetime maintenance, we should observe more, find problems and diagnose and treat them in time.
