As the new favorite of family flowers, Chinese rose is very popular, so how to cultivate Chinese rose?
1. Land selection: Choose a place with flat terrain, good drainage and ventilation and plenty of sunshine to plant roses. After the plot is selected, it is necessary to investigate and test the soil to determine its texture, structure, fertility and pH, and then decide whether to improve the soil according to the results.
2. Ploughing: The depth of land ploughing depends on the age of plants. Generally, the planting depth is about 10cm, the planting depth is about 25-30 cm, and the planting depth for more than 3 years is about 50 cm. When plowing, break clods and remove stones, tiles and weeds.
3. Application of base fertilizer: There are two common base fertilizers. One is organic fertilizer, such as plant ash, dried chicken manure, cow dung and soil miscellaneous fertilizer, which is generally applied at 0.5- 1 kg per square meter. The other is inorganic fertilizer, which mainly refers to chemical fertilizers, such as calcium superphosphate, ammonium bicarbonate and compound fertilizer. Generally, fertilization is about 0.4 kg per square meter.
4. Planting: treat the rose seedlings to be planted, control the planting density, plant them on the flat land according to the fixed row spacing and plant spacing, and then pay attention to daily management such as watering, fertilizing, loosening soil and weeding, pruning and shaping, and wintering. Only by doing a good job in field management can the Chinese rose grow as long as possible, and the specific management methods will not be introduced here.
Precautions:
1, light and temperature
Rose likes the light, and it should be kept in sunny places in spring, summer and autumn. Strong vitality, the optimum growth temperature is 15-25℃. In this temperature range, the flowers are large and beautiful, but they grow slowly at 30℃, and the flowers that bloom above 30℃ become smaller and lighter in color. It should be noted that too strong light is not good for bud development. Before flowering,
2. Water and fertilize
Rose is vigorous and grows rapidly, and needs a lot of fertilizer. When potted, "Woye foliar fertilizer" can be sprayed appropriately, and topdressing can be applied appropriately after pruning. In addition, potted roses don't need to be watered often, so be careful not to water them, but to water them thoroughly.
3. Dressing and shaping
Roses grow very fast and need to be pruned regularly, usually once every three months. After Tomb-Sweeping Day, it can be carefully pruned, so that the strong branches of the rose can be selected and left, and other branches, weak branches, crossed branches and excessively dense branches should be cut off. The selected branches should have 3-5 bud eyes from the base, and all the above branches should be cut off, so that the plants can absorb a lot of nutrients from the soil and supply them to the leaves and buds of the branches left after pruning. Remember to prune after germination. Pruning will affect the first flowering, and the growth height should be consistent. Each plant can retain 3-5 main branches, with a maximum of 7 branches.
4. Change soil and pots
Chinese rose should change pots every year or every other year 1 time, and change pots during dormancy. When putting the pot, you should trim the roots, shorten the old roots and promote new roots, but the roots should not be too heavy. When planting, pay attention to the stretching of the root system, the plants should be straight, and the pots cannot be filled. After changing the basin, water it twice.
5, pest control
Mainly to prevent and control rose diseases and insect pests, spray fungicides regularly in high temperature, high humidity or rainy season, and spray sulfur mixture during seedling dormancy to carry out comprehensive sterilization.
