Cultivation method of rainbow arrowroot
Rainbow arrowroot has become a star variety in the indoor leaf-viewing plant world due to its gorgeous leaf texture. However, many novices often encounter problems such as burnt edge of blades and growth stagnation during the maintenance process. This article will systematically analyze the scientific maintenance system of rainbow arrowroot to help you create a good ornamental product with shiny leaves and clear markings. 1. The golden rule for controlling temperature and humidity in the best growth environment The temperature control of rainbow arrowroot needs to grasp the golden range of 18-25℃, and the environment above 12℃ needs to be maintained in winter. It is recommended to place a humidification tray under the flowerpot to maintain the air humidity of 60%-70%. When the temperature exceeds 28℃, atomizing water spray can be used to cool down and increase humidity. The intelligent lighting adjustment plan adopts the strategy of "shading in three seasons and filling in light in winter": gauze curtains with a shading rate of 50% are used from May to September, and direct soft light in the morning and evening can be accepted from October to April of the following year. If leaf fading occurs, a plant fill light with a color temperature of 6500K can be configured to illuminate it for 3 hours a day. 2. Scientific management of water and fertilizer, precise irrigation system, rainbow arrowroot cultivation method
Adopt the "knuckle detection method": insert the index finger into the pot soil and water when the second knuckle is dry. It is recommended to use acidified water with a pH of 5.5 -6.5 (2 drops of white vinegar per liter of water) and use it with the bottom suction basin to achieve continuous moisturizing. The "113 Fertilization Method" is implemented during the growth period of the nutrient supply plan: liquid leaf observation fertilizer (N-P-K=3-1-2) once a week, chelated iron foliar fertilizer once a month, and organic fertilizer supplemented with decomposed sheep manure once every three months. Stop fertilization during winter dormancy. 3. Reproductive upgrading skills Select three-year-old mother plants in the entire process of rationing, and combine them with pot change for rationing in spring. Keep 4-5 functional leaves in each clump, and apply charcoal powder to the incision. Use a substrate with peat: perlite: vermiculite =5:3:2, bag and moisturize for 2 weeks after planting.
