Picture of meaty Oprina old pile
Meat enthusiasts have a special liking for the lignified stems of Oprina's old piles, but the cultivation process requires key skills. This article will systematically analyze the scientific methods to promote stem lignification through environmental control, and combine the maintenance experience verified by three years of practical practice to help you create beautiful old Oprina piles. The precise water control technique, the core element of Oprina's old pile cultivation, adopts the "alternating dry and wet" watering method, and delays watering for 3 days after the basin soil is completely dry. It is recommended to use the bamboo stick test method: insert the bamboo stick into 2/3 of the basin soil, observe that there is no moisture at the tip, and then replenish water. Pay attention to maintain a watering cycle of 15 - 20 days in spring and autumn, shorten it appropriately to 10 - 12 days in summer, and extend it to 25 - 30 days in winter. The stepped lighting scheme implements the "3 + 2 + 1" lighting strategy: 3 hours of direct exposure +2 hours of scattering every day in spring, 1.5 hours of direct exposure in the morning and evening in summer, and 5 hours of full sunshine in autumn. When used with a fill light, it is recommended to choose a red light source with a wavelength of 640 - 660 nm. Filling light for 2 hours a day can accelerate the lignification process. The temperature difference control system creates a temperature difference environment of 8 - 10 ℃ between day and night, maintaining 22 - 25 ℃ during the day and dropping to 14 - 16 ℃ at night. It is recommended to use intelligent temperature control equipment, and pay special attention to summer ventilation strategies: the air displacement per hour needs to reach 3 - 5 times the plant volume, and a small USB fan can be used to achieve circular ventilation. The scientific fertilization system adopts a "3:1:5" nutrient ratio (ratio of nitrogen, phosphorus and potassium), and slow-release fertilizer granules are applied every month. It is recommended to make self-made bone meal fertilizer: After crushing the cooked animal bones, mix perlite in a ratio of 1:20, and apply 5g every quarter. Pay attention to increasing the application of alginic acid during the growth period and stopping nitrogen fertilizer during the dormant period. Advanced points for maintenance of old piles regularly observe the changes in the stem skin. When longitudinal cracks appear, manual peeling can be carried out: use disinfectant tweezers to remove 0.2 mm of aging tissue on the surface layer to promote the development of secondary xylem. Cooperate with rotating flower pots (45 degrees per rotation) to ensure uniform light reception and avoid lignification on one side.
Through the above-mentioned systematic cultivation plan, high-quality old piles with a diameter of more than 1.5 cm can be formed in 18 - 24 months. Pay attention to regularly check the root status and replace 70% of the particulate soil substrate every two years to ensure the continued healthy growth of plants.
