Various Terms for Flower Cultivation
Ⅰ. Techniques for Water Management
1. Key Water Control Techniques
The扣shui technique promotes the accumulation of plant nutrients through phased water control, suitable for drought-resistant varieties such as succulents. Combined with the "better dry than wet" principle, it can effectively prevent root rot.
2. Scientific Watering Methods
The "wet when dry" method requires watering thoroughly after the topsoil is dry for 2-3 centimeters, and combined with the "return water" technique, it can improve fertilizer absorption rate and prevent uneven root development caused by "waist water."
Ⅱ. Scientific Soil Proportioning
1. Physical and Chemical Properties of Substrate
pH value measurement is the foundation of soil mixing, with most flowers suitable for a slightly acidic environment of 5.5-6.5. Adjusting the humus content (recommended 15-20%) can improve the granular structure of the soil.
2. Soil Texture Grading Standards
Divided by particle size into sandy/loamy/clayey types, the ideal cultivation soil should have the texture characteristics of "moist but not sticky," with a water retention and breathability ratio of 3:7 being optimal.
Ⅲ. Light Control Strategies
1. Key Points of Spectral Management
The UV-B band (280-315nm) can promote the synthesis of anthocyanins, but note that glass can filter more than 50% of effective UV rays. The recommended light intensity is maintained at 8000-12000 lux.
2. Setting of Supplemental Lighting Cycles
Using the sunrise and sunset simulation method, gradually adjust the duration of lighting. Ensure 6 hours of direct sunlight during the flowering period, and combined with intermittent supplemental lighting can improve the quality of flowering.
Ⅳ. Fertilizer Application System
1. Nutrient Supply Plan
Base fertilizer is mainly slow-release organic fertilizer, and top dressing is combined with water-soluble fertilizer. The巩shui technique can extend the efficacy of fertilizer by 30%, and the concentration of foliar application needs to be controlled between 0.2%-0.5%.
2. Timing of Fertilization
Follow the "four-stage fertilization method": nitrogen fertilizer is mainly used in the germination stage, phosphorus and potassium fertilizers are increased in the bud formation stage, trace elements are supplemented during the full bloom stage, and fertilization is stopped during the dormant stage.
Systematically mastering professional terms for flower cultivation not only improves communication efficiency but also allows precise control of maintenance parameters. It is recommended to establish a maintenance log, regularly test key indicators such as EC value and pH value, and optimize cultivation plans through data recording to truly enter the stage of scientific management of plant maintenance.
