The Renewal and Revitalization of红花酢浆草 (Oxalis rubra)
This article introduces the related topics of红花酢浆草, a herbaceous flower, focusing on its renewal and revitalization. The editor will provide a detailed explanation for you.
红花酢浆草 is easy to survive, has a strong growth momentum, a long flowering period, and is loved by the general public. However, due to粗放 daily management, there is a phenomenon of planting without management in many areas. This has led to the plants becoming crowded, the roots moving upwards, the weakening of water and nutrient absorption, a decline in growth year by year, a small number of flowers, a shortened flowering period, and in severe cases, large areas of withering, affecting its ornamental value. Based on years of cultivation experience, the author tries to analyze the causes of aging and introduces methods for revitalization for reference.
Causes of Aging:
红花酢浆草's underground鳞状茎 is spindle-shaped, covered with a brown hard outer layer, and has a terminal bud on top. When the terminal bud is damaged, a large number of lateral buds around it sprout, and adventitious roots can grow from the base. In spring, when the temperature rises,红花酢浆草 begins to tiller, and the base of the plant on the bulb gradually swells to form a new bulb. This tillering occurs about twice a year, once after a mass revival in spring and once at the end of summer dormancy. With the increase in tillering and the growth of new bulbs, the bulbs continue to move upwards, causing the roots to gradually approach the ground, a phenomenon known as "jumping roots". According to the author's observations, the second and third years after planting红花酢浆草 are the peak period of tillering, with a large number of flowers. After the fifth or sixth year, the tillering ability gradually decreases, most bulbs have jumped out of the ground by more than 5 centimeters, the growth is significantly weakened, and it is prone to sunburn and frostbite, as well as susceptible to diseases and pests. A cross-section of the new bulb shows an internal white color; while a cross-section of the bottom aging bulb shows a moderate red color and has lignification.
Renewal and Revitalization:
红花酢浆草 is easy to plant and grow. Renewal and revitalization can be combined with division propagation throughout the year, with the best division time in the North China region being from early March to the end of April. At this time, the survival rate of division and revitalization planting is high and does not affect the growth and ornamental effects of红花酢浆草. Additionally, after the summer dormancy of红花酢浆草, it is also a good period for division and revitalization.
1. Transplanting seedlings: Use a spade to dig up the entire old plant, gently remove the soil around the roots, and pile them up. When digging, keep a little distance from the plant to avoid injuring the bulbs, and make sure the spade is dug straight down, not diagonally, to avoid injuring the bulbs.
2. Division: Remove the withered and damaged leaves of the dug红花酢浆草 and remove about 1/2 of the old leaves to reduce transpiration and water loss after planting. Use a sharp knife to cut off the lower old bulb, with the cut surface preferably below the first or second new bulb, so that after planting the seedlings with 1 to 2 new bulbs, they can remove the lower old bulb and update and revitalize; and ensure that the new plant has enough nutrients to quickly sprout and bloom. Finally, dip the cut surface of the new bulb in fresh wood ash to prevent rot.
3. Fertilization: Add organic fertilizer to the flower bed where the old seedlings were dug and turn the soil deeply while removing withered leaves and weeds. Generally, apply 0.5 to 0.8 kg/square meter of decomposed cake fertilizer and add an appropriate amount of phosphorus and potassium fertilizers to meet the flowering needs of红花酢浆草.
4. Planting:红花酢浆草 grows rapidly, and each plant can propagate 3 to 9 small seedlings in a year. When planting, usually use a triangular hole planting method with a spacing of 25x35 centimeters. Dig a hole 8 to 10 centimeters deep with a small trowel, place 4 to 6 bulbs in each hole according to their size, and cover with 3 to 4 centimeters of soil, making sure the leaves are exposed above the ground. Of course, the trench planting method can also be used, with a general spacing of 15 to 30 centimeters, and water should be added 2 to 3 days after planting to prevent bulb rot.
Enhanced Management:
Strengthening the daily maintenance management of红花酢浆草 can also effectively delay the occurrence of aging phenomena. The flowering period of红花酢浆草 is as long as more than 5 months, and a large amount of fertilizer and water is needed during the growing season. Fertilization and watering should be done in a timely manner. Before the revival of红花酢浆草 in spring, apply 15 to 20 kg of compound fertilizer per mu, which can be applied in holes or sprinkled according to soil moisture conditions. After that, fertilize every 20 days, and pay attention to the prevention and control of diseases and pests. In July and August, when the temperature rises,红花酢浆草 enters a dormant state and stops growing. To prevent sunburn damage to the new stems exposed on the ground, cover the soil. The thickness of the soil cover should be determined according to the annual upward movement of the new stems of红花酢浆草, generally 2 to 3 centimeters.
In summary, based on the continuous tillering and upward movement of new stems of红花酢浆草, strengthening daily management and maintenance, enhancing plant growth, delaying aging phenomena, and dividing and updating when necessary, can make the robust红花酢浆草 beautify our environment in the most beautiful way.
