Breeding methods and matters needing attention for yellow hair palm
As a very ornamental variety in the cacti family, Huangmao Zhang is favored by plant lovers for its fluffy palm-shaped stems and leaves. However, many novices often encounter problems such as plant wilting and rotten roots during the maintenance process. The reasons are mostly related to improper basic maintenance methods. Environmental regulation determines that the key soil substrate for survival selects standard sandy loam as the ideal substrate, and the proportion of coarse sand with a particle size of 0.5-2mm must be more than 40%. It is recommended to adopt a ratio plan of legus soil: river sand: perlite =3:5:2 to ensure that the drainage rate is controlled to fully penetrate within 5 seconds after watering. Light intensity gradient management Keep full sunshine for 6-8 hours in spring and autumn, and use a 50% sunshade net to filter strong light in summer. During indoor maintenance in winter, it is recommended to keep a distance of 0.8-1.2 meters from the southbound window and use the plant fill light to fill the light for 3 hours a day. The intelligent watering mode for daily maintenance and fine operation adopts the bamboo stick detection method: Insert a bamboo stick with a diameter of 3mm into 2/3 of the pot soil, let it stand for 20 seconds, and then pull it out for observation. Water is carried out when the bamboo sticks are completely dry. The amount of watering each time is based on the seepage from the drainage holes on the bottom of the basin. Winter should be extended to 3 days after the bamboo sticks are dried before watering. Scientific fertilization plan Apply 5-8 grains of slow-release fertilizer every month during the growth period (April to September), combined with foliar spraying of potassium dihydrogen phosphate (concentration 0.1%). After fertilization, air blowing should be used to remove residue on the palm surface to prevent the accumulation of fertilizer solution and causing burns. Special stage maintenance strategy Root health maintenance Keep 1/3 of the soil protective soil when changing pots. After pruning, the root system needs to be soaked in 800 times carbendazim solution for 15 minutes. The diameter of the new basin should be 3-5cm larger than that of the original basin, and a 3-cm-thick ceramsite drainage layer should be laid on the bottom of the basin. Technical points for cuttage propagation Select two-year-old strong stem nodes, cut at a 45° angle, dry them, and insert them into a substrate with vermiculite: perlite =1:1. Keep the temperature at 25-28 ° C, the humidity at 60%, and the roots are grown for about 20 years. Cultivation methods and precautions for yellow hair palm common problems response plan When the base is found to be soft when handling physiological diseases, immediately remove the pot and check the root system. The decomposed part needs to be completely removed to healthy tissue, and the incision needs to be re-planted after applying sulfur powder. Maintain micro-moisture in the substrate during the recovery period and avoid direct sunlight. During the period of high incidence of scale insects for comprehensive pest control (May-June), the gaps between stems and nodes are wiped with a 75% alcohol cotton sheet every week. In severe cases, use 2000 times of spirotetramat solution to spray it continuously for 3 times, with an interval of 7 days.
By establishing a scientific maintenance system, yellow hair palm can maintain vigorous growth for 8-10 years. The key is to grasp the "dry farming principle" and adjust management measures in accordance with seasonal changes. Only by regularly observing the status of the plant and promptly handling abnormal situations can this desert elf show its unique charm in the urban space.
