How to make dripping Guanyin leaves big
As a star species among tropical leaf-viewing plants, Dishui Guanyin is deeply loved by horticulture enthusiasts for its unique Buddha spaths and wide leaves. If you want to cultivate giant leaves with leaf surfaces of more than 30 centimeters wide, you need to master systematic maintenance skills. This article will provide you with a detailed analysis of the mystery of Dishui Guanyin leaf development from four dimensions: light regulation, nutrient supply, water management to root maintenance. Light regulation: The golden rule of photosynthesis is balanced between light duration and intensity. 3-5 hours of scattered light every day is the key to leaf development. In spring and autumn, it is recommended to receive direct light before 9 a.m., and in summer, use a sunshade net to filter 50% of the strong light. It is worth noting that long-term exposure to light below 2000Lux will lead to long petioles and thin leaves. Rotating potted plants receive balanced light. Rotate the flowerpot 45 degrees clockwise every 7 days to avoid unilateral phototactic growth and maintain perfect symmetry of the plant type. In winter, it can be increased to 5 hours of full sunshine per day, and the effect is better when used with a fill light. Nutrient supply: Fertilization plan for the growth period of the power engine with expanded leaves. The "bi-weekly cyclic fertilization method" is used in the peak growth season from March to October: liquid fertilizer with N-P-K=20-10-10 (diluted 1500 times) is applied in the first week, and trace element fertilizer containing iron chelate is used in the second week. Adding 2% ferrous sulfate solution every month can effectively prevent yellow leaf disease. Fertilization in winter is taboo. When the environmental temperature is below 15℃, the absorption capacity of the roots will drop by 80%. Solid fertilizers should be stopped at this time. 0.1% potassium dihydrogen phosphate solution can be sprayed on the leaves every 20 days to maintain the health of the leaf cuticle. Moisture management: Moisture control precision artistic substrate moisture content monitoring adopts the "knuckle detection method": Insert your index finger into the second knuckle of the basin soil, and you can water it when you feel the slight moisture. Keep the air humidity above 70% in summer, and the humidity of the small environment can be maintained through an atomizing humidifier. Siphon watering technique Use a long-spout pot to slowly fill water along the edge of the basin until the drain hole seeps out. Pervious leaching is carried out once a month to prevent salt accumulation. Remember to avoid stagnant water in the heart of the leaves to avoid causing soft rot. Root maintenance: The fundamental guarantee for sustainable growth is the timing of pot change. When the aerial roots are exposed to the soil surface or the roots are intertwined at the bottom of the pot, the pot needs to be changed. The best basin change period is before and after the Qingming Festival, when red pottery pots are used with a mixed substrate of peat soil: perlite: leaf soil =5:3:2. The root trimming and disinfection process cuts off dark brown aged roots and retains new white roots with a diameter of more than 2 mm. Apply charcoal powder to the incision for sterilization, and dry the roots for 2 hours before planting. After changing the pot, place it in a cool place to slow down the seedlings for 7 days, and gradually restore the light.
Through the establishment of the above-mentioned four-dimensional maintenance system, combined with detailed management such as regular wiping of leaf surfaces and preventing scale insects, the remarkable effect of increasing the blade diameter by 50% can be seen in about 6 months. It is recommended to take growth record photos every month, establish maintenance files, and accurately grasp the growth rhythm of plants. When the blade cracks laterally, it means that the growth limit has been reached. At this time, fertilizer should be properly controlled and the maintenance stage should be entered.
