Rose Winter Management Technology
First, fine pruning late autumn and early winter, when the temperature dropped to 5 °C, first cut dead branches, branches and branches, cross branches, overlapping branches, etc., and then depending on the plant growth to trim. For plants that are not growing well, strong shearing should be carried out. The whole plant can be cut by 2/3, and 3 to 4 main branches from 1 to 3 years old can be reserved. The base is left about 20 centimeters long, so that the nutrient supply can be concentrated. Potted rose varieties. For normal growing plants, moderate pruning, cut 1/2 of the main branches, suitable for rose varieties that are easy to sprout branches. Plants that grow strong should be weakly cut. Note: When trimming, sharp edges are required, and clipping is smooth. The branches cut off and the leaves on the ground must be burned and the plants should be sprayed once with lime sulfur. Second, buried fertilization Material on the ground rose, can be dug in the plant root after the excavation of the outer ring of the root ditch, depending on the size of the plant, each plant buried 250 to 300 grams of cake fertilizer, can also be used 500 grams of chicken, duck dung or 2.5 ~3 kg of Feitang Mud to meet its growth and flowering needs for the following year. After planting, the potted plants can be removed from the pots, shake off part of the soil, cut the roots that have rotted and died, fertilize loose fertile cultured soil, and bury the plant in the middle and lower part of the flowerpot. The decomposed cake fat can meet the needs of growth and flowering in the following year. Third, pay attention to the cold in the northern winter is relatively cold, the cultivation of the rose in the winter should not be the strength of pruning, can be trimmed before the spring of the following year. Potted plants can be buried in leeward sunny areas together with plastic sheds to keep the pots free from icing. If pelvic soil freezes for a long time, it will affect the growth and flowering of the following year. For plants placed indoors, the temperature of the greenhouse should not be higher than 5°C so that it can be fully dormant. Fourth, Zhuangzhi cutting for some of the easy-to-root rose varieties, such as Elizabeth, Moon Yuehong, Fenghua, etc., can be cut off the thick one-year-old branches, cut into the growth of 10 to 12 centimeters ear section, the lower incision below the Festival 0.2 centimeters, with yellow heart soil cutting bed, cutting into the soil depth of 4/5 of the total length, retaining only one end of the bud outside the soil, after the permeable water arched shed, plastic film pressed tightly around, when the weather is too cold when stamped Grass curtains protect against cold, and by the spring of the following year, the lower incision can heal and take root.
