How to manage orchids after changing pots
The golden maintenance period after the orchids are changed directly affects the survival rate of the plants. At this time, the root system is in a sensitive stage of adapting to the new environment. Mastering scientific maintenance methods can not only help orchids quickly consume pots, but also accumulate energy for subsequent growth. This article will systematically analyze the key maintenance points after basin replacement, from environmental control to light management. Environmental control trio precise temperature control. Newly replaced orchids need to maintain a constant temperature of 15-25 ° C, and the temperature difference between day and night should be controlled within 5 ° C. It can be naturally maintained in spring and autumn. In summer, it is necessary to avoid direct air conditioning. In winter, it is recommended to use heating pads to keep the substrate temperature stable. Sudden changes in temperature can lead to disorder of root absorption function, manifested by yellowing of leaf tips. Humidity gradient management creates 60-70% air humidity through the basin method: the outer container is covered with moist ceramite, and the inner basin is placed in the air. The moisture content of the substrate is controlled at about 40%, and the bamboo stick detection method is used-the bamboo stick is inserted into the plant material for 2 hours and then pulled out. Only the tip is moist. Avoid spraying to moisturize. The accumulation of water droplets in the heart of the leaf may cause soft rot. Advanced strategy for water and fertilizer management Scientific water control cycle Establish a stepped watering plan within 30 days after pot change: in the first 10 days, a small amount of water will be moistened along the pot wall, in the middle 15 days, until 1 cm of the plant surface is dry before watering thoroughly, and in the later stage, routine watering will be gradually resumed. It is recommended to use a long-spout pot to inject water at a fixed point to prevent water from impacting false bulbs. The timing of nutrient supply strictly follows the "three no application" principle: no application before new roots germinate, no application on rainy days, and no application during high temperature periods. It is recommended to apply 3000-fold diluted amino acid water-soluble fertilizer on a cloudy evening after 45 days of changing pots, and the effect is better when combined with EM bacterial solution for root irrigation. The light control system plan adjusts the light intensity in stages after changing pots: completely shaded for the first 7 days, receive scattered light before 9 a.m. on days 7-15, and gradually extend to 3 hours of morning light every day after 15 days. Maintain 50% light transmittance when using sunshade nets. It is recommended to use them with ultraviolet filter films in southern regions. The scientific proportion of ventilation adopts the "3+3 circulation ventilation method": forced ventilation is guaranteed three times a day, each time lasts for 30 minutes, and the air flow rate is controlled at 0.3-0.5m/s. A circulating fan can be installed for indoor maintenance to form a diagonal airflow with window ventilation. Pay attention to avoid direct wind blowing. Excessive wind speed may lead to dehydration of the blades.
After 30-45 days of careful maintenance, when new buds are observed to germinate and the leaves show waxy luster, it means that the orchids have been put into the pot. Normal maintenance can be resumed at this time, but the root condition still needs to be continuously observed. It is recommended to use transparent pots to observe the root tip growth points every quarter and adjust the maintenance plan in time.
