How to plant mountain roses in spring
As the "never wither rose" in the fleshy world, mountain roses have captured the hearts of countless plant lovers with their unique rosette shape. Spring is the golden time to sow mountain roses. Mastering scientific planting methods can increase seed germination rate by more than 40%. This paper systematically analyzes the five core operating points from substrate treatment to post-maintenance. The ratio plan for substrate preparation and disinfection treatment soil uses peat soil + perlite + vermiculite mixed in a ratio of 2:1:1 to ensure that the substrate is loose and breathable. The proportion of particulate media needs to be more than 30% to prevent water accumulation and root rot. Double disinfection method exposure disinfection: Lay the mixed soil in the sun for 3 days, and use ultraviolet light to disinfect it. Chemical disinfection: Dilute carbendazim solution at a ratio of 1:800 and evenly pour through the substrate. Seed selection and treatment skills Quality identification standards Select new species of the year with full grains and diameter> 0.8 mm, and the germination rate of old seeds will be reduced by 60%. Shell seeds are removed through submerged testing. The scientific disinfection process is soaked in 0.1% potassium permanganate solution for 30 seconds, washed with clean water three times, and placed in a cool place to dry to effectively prevent black rot. Operation Guide for Precise Sowing On-demand positioning skills Use a disinfected toothpick dipped in water to stick the seeds, and order the seeds at a distance of 2cm. Avoid covering with soil. Seeds need to be stimulated by scattered light before they can germinate. Micro-environment control covers transparent plastic wrap to create a greenhouse effect. The corners of the film are opened for ventilation from 10:00 to 15:00 every day to maintain a 60% humidity environment. Intelligent maintenance management plan temperature and light control to maintain the optimal temperature of 18-25℃, and set up sunshade nets to filter noon strong light. During the seedling stage, soft light irradiation is required for 4 hours/day. Gradually, the ventilation time was extended on the third day after sprouting, and the film was completely peeled off after 7 days. Increase light intensity by 10% every week for adaptive training.
Through the above systematic operations, the survival rate of mountain rose sowing can reach more than 85%. It is recommended to transplant seedlings in pots when three pairs of true leaves are grown, and with phosphorus and potassium supplementation once a month, a perfect "rose flower plate" with a diameter of 5 cm can be cultivated in half a year. Remember to rotate the flowerpot regularly to ensure that the plant type is symmetrical, so that each mountain rose will bloom with its unique charm.
