What are the techniques of peony cultivation and management?

Chinese peony has a wide range of ecological adaptability, so cultivation is easy and management is simple. However, in order to make it luxuriant and colorful, it is also necessary to emphasize the following points.

First, select varieties of seedlings and land

Chinese peony is a temperate plant. It is cool and hot, it should be dry and wet, Xiyang is slightly resistant to half yin, and it has developed deep roots. Therefore, the choice of “appropriate flower” will make it easier or later for future cultivation and management. Very important. Therefore, it is the best choice for cultivating Chinese peony and it is best to use raw soil, clay, saline-alkali soil as well as to choose high-pitched terrain, spacious ventilation, lateral shade, and a deep, loose, fertile and well-drained soil. Land In addition, important depressions that have been planted with peony should be planted one year to two years after rotation.

Second, timely planting

Autumn is the best time to plant peony. As the saying goes, there is a saying that “spring equinox planted peony and it does not bloom until old”. The specific planting period is appropriate from mid-September to late-December. In this period, early planting is preferred, and the early planting of the soil is warm and high, which can promote the emergence of new roots of the seedlings in the early stage, which is conducive to survival, wintering, and the growth of the following year. Planting methods are usually carried out at the same time as the propagation of the ramets. Irrespective of hole planting, ditch planting or pot planting, the empty tone should be wide and long. After mixing in the bottom of the mature basal fertilizer, the root system is evenly distributed and naturally stretched, and cannot be curled together. The depth of planting should be such that the root neck is flush with the soil surface or slightly lower, not too deep or too shallow. When the soil is closed, it should be filled with layers of clay and the layers should be solid, and then the water should be poured and the soil should be overwintering.

Third, timely and appropriate amount of water should be fertilized

Watering should be based on the principle of keeping the soil moist and not too wet. In general, seedlings that are planted are to be irrigated with water. Before entering the winter, they must be irrigated with water. Others can be watered with flowers as appropriate.

Chinese peony is hi-gaining fertilizer. Appropriate timely and appropriate fertilization can not only promote flowering, flower blooming, full flower type, but also prevent or reduce the phenomenon of flowering “small year”, flower type degradation, and double-valve reduction in some varieties.

Fourth, reasonable pruning

The axillary buds, dead branches and diseased shoots should be promptly removed to maintain the dynamic balance between the above-ground and underground parts, keep the plants with balanced and appropriate branches and beautiful plant shape, make them airy and transparent, concentrate the nutrients, and grow vigorously. Consistent flowering. The main measures include the following:

1, choose to leave branches

After the peony is planted, it is allowed to grow in the first year, and sprouts can be sprouted outside the root neck (commonly known as soil buds); when the saplings grow to about 10cm in the second spring, they can be selected from several strong and full-grown varieties. Those who are evenly distributed are retained as the main branches (commonly known as fixed shares), and the remaining ones are all removed. Afterwards, one or two new shoots will be selected and kept as branches for each year or every other year so that the strains will grow and plump year by year.

2. Use sprouts as appropriate

In order to make the peony large and beautiful, often with pruning buds, buds work, so that each branch retains one bud, the remaining buds removed, and all old shoots of the adventitious buds cleared to make nutrient concentration, Flowering huge. The buds retained on each branch should be full and robust. Some varieties have strong growth potential, strong branching ability and high flowering rate. There are often 1-2 or even 3 buds on each branch that can germinate into branches and bloom normally. For each of these varieties, some shoots can be left as appropriate. In order to increase the amount of flowers and appropriate extension of the flowering period; and some varieties with weak growth, weak branching force and low flowering rate should adhere to 1 pruning method to retain 1 bud.
