How often are orchids watered in spring
As a representative of elegant flowers, orchids enter their golden period of growth in spring, and their watering management directly affects the flowering quality. Only by correctly grasping the three key elements of watering frequency, water quality selection and subsequent maintenance can orchids show their best posture in spring. 1. Scientific watering method for orchids in spring 1. Judgment standard for watering cycle A watering cycle of 5-7 days is recommended in spring, but it needs to be adjusted in conjunction with the state of the plant material: ① Insert 3cm of bamboo sticks into the plant material and pull it out without moisture to replenish water ② When the surface of the plant material becomes white and the pot body becomes lighter, Water immediately ③ After the vernal equinox, shorten to 4-5 days/time as the temperature rises 2. Environmental factors adjust the use of spray water replenishment in dry areas in the north, and intermittent watering is used in the plum season in the south. Thick-leaf varieties such as Jianlan require 20% less water than Chunlan, and require targeted adjustments. 2. Special water quality ratio plan for orchids 1. Natural rainwater treatment techniques Collecting rainwater requires 3 days of standing and sedimentation, adding EM bacterial solution at a ratio of 1:1000 for activation, and controlling the pH value at 6.0-6.5 is the best. When the nitrogen content of rainstorm water is high, it needs to be diluted with 30% cold boiled water. 2. Tap water improvement plan Four-step method for chlorine removal: ① After receiving water, expose it to the sun for 12 hours ② Add activated carbon to filter ③ Add 2ml of vitamin C solution per liter of water to neutralize ④ Leave it for 24 hours and then use it. 3. System maintenance after watering orchids 1. Gold 6-hour management water immediately turns on the circulating fan after watering, maintains the air flow rate of 0.5m/s, and maintains the environmental humidity of 60%-70%. Avoid direct strong light within 6 hours. It is recommended to use gauze with a light blocking rate of 40%. 2. The temperature is collaboratively controlled to keep it at 18-25℃ during the day and not lower than 15℃ at night. When using a bottom heating mat, ensure that the bottom of the basin and the mat maintain a 2cm ventilation gap. 4. Advanced maintenance techniques Implement permeable flushing once a month: Continuous watering with warm water at 30 ° C for 3 minutes can effectively drain the salt accumulated in the plant materials. Adding Cyanjunwang biological agent combined with watering can increase the nutrient absorption rate by 40%.
To master the space-time art of watering orchids in spring, we need to follow the principle of "depending on the sky, depending on the quantity of plant materials, and depending on the adjustment of varieties." By establishing a watering log to record changes in temperature and humidity, and cooperating with regular plant material testing, a personalized maintenance plan can be gradually formed to make orchids flourish in spring.
