A Detailed Guide to Rosa roxburghii Planting Techniques and Field Management Methods
Rosa roxburghii, also known as sour pear and wood pear, is a relatively rare fruit. It is rich in vitamin C and has nourishing and health-building effects. In addition, it has extremely high medicinal value, can enhance the body's resistance, and has the effects of preventing and fighting cancer and treating scurvy. Let's 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 average annual temperature of around 12-16 and annual precipitation of more than 1000 milliliters. It has no strict requirements for soil, but fertile, loose, and well-drained acidic or slightly acidic soil is best, as this is beneficial to its growth and development as well as its yield and quality.
2. Propagation Methods
The propagation methods of Rosa roxburghii mainly include 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 before sowing. This can both advance germination and increase the germination rate. Except in winter, cuttings can be done in the other seasons. Cut off the current year's branches from robust growing plants, cut them into 10-12 cm 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, firm the soil, and it will 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 field planting, prepare the land and apply fertilizer at the planting site, then dig planting holes at a spacing of 1.5×2 m. The holes should be 50 cm 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 filling the soil, generally lift the seedling upward a little to let the root system spread out, then cover with soil and firm it, and water thoroughly after planting.
4. Field Management
After field planting, water and fertilize reasonably according to the plant's growth conditions. 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 the plants grow robustly. Also pay attention to pest and disease damage. The main pests and diseases of Rosa roxburghii include powdery mildew, aphids, slug moths, bagworms, black citrus whiteflies, and fruit borers, etc. They can all affect plant growth, causing weak growth in mild cases and death in severe cases, so pest and disease prevention and control work should be done well.
