Peony is a famous flower in China. It is mainly distributed in the Huang-Huai River basin. Its colors are yellow, white, red, purple and green. Its colors, fragrances, postures, and rhyme are all excellent. It is often known as the “King of Flowersâ€. With the development of landscaping and the improvement of residents' living standards, the demand for peony is increasing, and the planting benefit is considerable. According to the characteristics of its low density, the following breeding methods are adopted. Not only is the operation simple and the survival rate is high, but it also saves time, material, and costs. Suitable habitat Peony Hi-fertilizer, more resistant to cold, roots prone to rot during prolonged periods of stagnant water. Suitable for growing in neutral soil, slightly alkaline or slightly acidic soil can also grow. Mother tree selection and wooden frame (nutrition box) production Selection of vigorous growth, dense branches of the peony per plant as a mother plant, according to the size of the mother plant canopy size to create a wooden frame surrounding the mother plant, the height of the mother plant 1/4 to 1/3 of the height. Shoot selection and treatment In the mother plant, multiple buds with strong growth and strong growth were selected, and the roots were stimulated by cutting and twisting the branches 5 to 8 cm above the base. The frame and the supporting branch are first covered with a wooden frame to cover the mother plant, and the middle part of the selected branch is tightened and pulled outwards with a string so as to make it deviate from the mother plant. Then, the other end of the string is fixed on the edge of the frame, with a moderate thickness of the wood bar flattened on the inside of the wooden frame or braced on the ground, the upper end against the branch to make it bend. Fill the soil and water with a fine soil with no impurities and uniform particles to fill the wooden frame, and slowly water to wet the soil. In the frame period management, timely fertilization was performed according to the growth condition of the peony mother plant, the weeds in the frame were removed, and moisture was added to keep the topsoil in the frame moist. The rainy season should be drained in time to avoid water rot. In order to maintain the ground temperature and humidity, a simple plastic film shed should be constructed in the winter, and rooting can usually take place after 2 to 3 months of the mother plant. From the middle of October to the mid-November of the ramets and field cultivation, the fine soil around the branches was split and cut at 2 cm below the rooted part to be separated from the mother plant and planted in the field at a distance of 20 cm30 cm.
