Does the Ulmus桩 Soak in Water Under the Tree?
The Ulmus桩, with its sturdy and ancient appearance, is highly favored by bonsai enthusiasts. However, failures often occur during the initial care of new桩 due to improper handling. This article will analyze the misconceptions in桩 treatment and the criteria for survival from a scientific care perspective.
Taboos and Moisture Retention Strategies for Soaking Ulmus桩
Analysis of the Dangers of Soaking Treatment
The roots of Ulmus contain abundant tannins, and soaking accelerates the loss of nutrients. According to botanists, when the water content in the roots of Ulmus exceeds 35%, the formation speed of callus tissue decreases by 40%. A wound sealant should be used to treat the cut surface, combined with intermittent spraying to maintain air humidity between 65%-75%.
Four-Step Scientific Moisture Retention Method
① When using bagging for moisture retention, it is necessary to ventilate for 2 hours daily; ② The depth of sand burial should reach 2/3 of the桩 body; ③ Spraying should avoid the high-temperature period at noon; ④ The shading net should maintain a 50% light transmission rate. Practice shows that using a mixed matrix of vermiculite and river sand (1:3) can improve moisture retention by 30%.
Four-Step Diagnostic Method for Judging the Survival of Ulmus桩
Morphological Observation Indicators
① Daily growth rate of new buds > 0.3 cm; ② Thickening speed of leaves > 0.1 mm per week; ③ Interval between secondary germination ≤ 45 days. Experimental data show that the moisture content in the xylem of surviving桩 bodies remains stable between 28%-32%.
Physiological Metabolism Detection Method
① Shortening the drying cycle of the potting soil to 3-5 days; ② Area of bark regreening > 60%; ③ Callus completely wraps the section. It is recommended to use a thermometer and hygrometer for continuous monitoring. When the day-night temperature difference is stable within 8°C, the root recovery function can be judged.
Through systematic care management and scientific monitoring methods, the survival rate of Ulmus桩 can be increased to over 85%. It is recommended to record growth data monthly and establish a personalized care file.
