What is the focus of seasonal winter management? Regardless of whether they are cultivated in the ground or in potted plants, winter is the most important management period. Whether the conservation is in place directly relates to the normal growth and flowering in the coming year, and the following points should be focused on.
1. Fine pruning: In the late autumn and early winter, when the ambient temperature drops below 5°C, cut dead branches, branches and branches, cross branches, overlapping branches, etc., and then look at the growth of the plants. Use strong, medium, and weak. Method to trim. For weak plants that are not strong enough to grow, strong shears should be used to cut 2/3 of the whole plant, leaving only 3 to 4 main branches from 1 to 3 years old, leaving about 20 cm at the base to concentrate nutrient supply. , suitable for potted plant variety rose. For moderately growing plants, give moderate pruning, cut 1/2 of the main branch, suitable for easy flowering varieties. For those small and medium-sized plants that grow normally, they should be given weak shear to prevent excessive consumption of nutrients. Pay attention to pruning, require sharp knife, smooth cut, do not make cut on the cut, generally from the bud point 1 cm to 1.2 cm under the knife, keep the lateral buds, can promote plant ventilation and light and plant shape good. The cut branches and ground defoliation should be collected and burned, and the plants should be sprayed with lime sulfur, which will greatly reduce the incidence of diseases and insect pests in the coming year.
2. Buried fertilizer: Planted on the ground, after the completion of pruning, excavate the annular groove around the root of the plant, depending on the size of the plant, bury 250g to 300g of cake fat at each end, but also use 500g of chicken , Duck dung or Feitang mud from 2500g to 3000g, to meet its growth and flowering needs in the coming year. After the pruning is completed, the potted plants can remove the plants from the pots, shake off part of the soil, cut the roots that have been rotted, and replace them with fresh and fertile loose soil, and plant them in the middle and lower parts of the pots. 50 to 100 grams of roasted cooked fat cake, to meet its second year of birth and flowering needs.
3. Pay attention to the cold: the northern part of the winter is relatively cold, the ground cultivation of the Chinese rose in the winter should not be used for intensity pruning, to prevent dry wounds, can be trimmed before the late spring sprouting. Potted plants can be planted together with pelvic plants in a leeward sunny place, outside the plastic arch shed, to maintain the pelvic soil does not freeze, and if the basin soil freezes for a long time will affect the growth and flowering in the coming year. Pay attention to the plants resting in the room, the temperature of the greenhouse should not be higher than 4 °C to 5 °C, so that it can be fully dormant.
4. Zhuangzhi cutting: For some relatively easy-to-root rose varieties, such as 'Elizabeth', 'Moon Yuehong', 'Fenghua', 'Mini' rose, etc., they can cut the thick one-year-old branches and cut them up to 10 cm. The 12 cm section of the panicle, the lower incision is located 0.2 cm below the section, and the yellow soil is used as the cutting bed. The depth of the cutting is 4/5. Only one bud at the end is retained in the soil. After the water is permeable, an arch is erected to cover the plastic film. It is tightly pressed around, and when the weather is too cold, it is covered with cold curtains to keep the seedbed free of ice. In the coming spring, the lower incision will heal and take root.
