The Latest Rosa roxburghii Planting Techniques: A Step-by-Step Tutorial
Rosa roxburghii, also known as sour pear and woody pear, is a relatively rare fruit. It is rich in vitamin C and has a nourishing and health-building effect. In addition, it has extremely high medicinal value, can enhance the body's resistance, and helps prevent and fight cancer and treat scurvy. Let us take a look at its planting techniques below.
1. Planting Conditions
Rosa roxburghii prefers a warm and humid climate and can be planted in areas with an annual average temperature of around 12-16 and annual rainfall of more than 1000 milliliters. It is not strict about soil, but fertile, loose, well-drained acidic or slightly acidic soil is best, as this is favorable for its growth and development as well as its yield and quality.
2. Propagation Methods
The main propagation methods for Rosa roxburghii are sowing and cuttings. Sowing can be done in autumn or spring. Its seeds have no obvious dormancy period and can be sown once mature, with a survival rate of more than 90%. Before sowing, soak the seeds in warm water for 12-24 hours and then sow, which can both advance germination and increase the germination rate. Cuttings can be carried out in all seasons except winter. Cut off the current-year branches from robust-growing plants, cut them into 10-12cm sections, make a slanted cut below a bud at the lower end, and make a slanted cut above a bud at the upper end. Insert the branch into the soil with one bud exposed, press the soil firm, and it can take root in about one month. You can also apply rooting powder to the inserted part to increase the survival rate.
3. Field Planting
The time for field planting should preferably be from December to February. Before planting, prepare the land and apply fertilizer at the planting site, then dig planting holes at a spacing of 1.5×2 meters, with each hole required to be 50cm in length, width, and depth. Before planting, apply base fertilizer and a small amount of calcium, magnesium, and phosphate fertilizer to each hole. When planting, spread the root system out and do not let it twist together. When the hole is about half filled with soil, lift the seedling upward a little to spread the roots out, then cover with soil, press it firm, and water thoroughly after planting.
4. Field Management
After planting, water and fertilize reasonably according to the plant's growth condition. Water promptly during drought, and remember to drain during the rainy season to avoid excessive water accumulation affecting the root system. Also do a good job of cultivating and weeding so that the plants grow robustly. Also pay attention to pest and disease damage. The main pests and diseases of Rosa roxburghii include powdery mildew, aphids, stinging moths, bagworms, black citrus whiteflies, and fruit borers, all of which can affect plant growth, causing weak growth in mild cases and death in severe cases, so pest and disease control work must be done well.
