What to do with Clivia with an arrow?
Clivia with arrows is a common problem that plagues many flower lovers. When the tall and straight flower stems are trapped in the leaf sheaths and cannot be stretched, it not only affects the ornamental value, but also may endanger the health of the plant. This article will systematically analyze the causes of the arrow trap and provide scientific and effective solutions to help you create a perfectly blooming Clivia. 1. Nutrient supply plan 1.1 Organic fertilizer activates soil The soil that has not been changed for a long time is prone to hardening and deactivation. It is recommended to replace the special orchid substrate every spring and autumn. The ratio of fermented sheep manure to pine needle soil is 1:3, which not only retains water and air permeability, but also slowly releases nutrients. 1.2 Precise topdressing techniques Apply potassium dihydrogen phosphate (800 times liquid) to foliar spray every week during the bud emergence period, and combine it with beer fermentation liquor (1:50 mixed with water) to irrigate roots. Pay attention to applying thin fertilizer frequently and avoid burning the roots with thick fertilizer. 2. Environmental control strategy 2.1 Temperature and humidity management maintains the optimal temperature band of 18-22℃, which can drop to 15℃ at night to form a temperature difference. Use a humidifier to maintain 60% air humidity, and place a water pan at the bottom of the flower pot to increase humidity. Pay attention to avoid standing water. 2.2 The intelligent filling light solution guarantees 4 hours of direct light every day in spring and winter, and uses a sunshade net to filter 50% of the light in summer. During the extraction period of flower arrows, you can adopt the method of "covering dew during the day and night", and use a black plastic bag to block light for 4 hours a day to promote extraction of arrows. 3. Physical auxiliary measures 3.1 Leaf binding techniques Use wide strips of cloth to cross the leaves, reserving 2 cm of growth space. Wear gardening gloves during operation to avoid damage to the waxy layer on the leaves, and the binding time should not exceed 15 days. 3.2 Warm water stimulation method injects 35 ° C warm water into a narrow-necked pot and slowly irrigates it along the wall of the pot. The root system can be activated for 3 consecutive days. Use it to rotate the flowerpot (adjusted at 45° per day) to ensure that the plants receive even light.
Through three-dimensional solutions of nutrition regulation, environmental optimization and physical intervention, more than 90% of arrow pinching problems can be improved. During daily maintenance, pay attention to the status of leaf sheaths, intervene promptly in the early stage of flower stem outcropping, and cooperate with basic maintenance such as regular basin rotation and cleaning leaf surfaces to effectively prevent recurrence of arrow pinching.
