Greenhouse Diffuse Glass – The Complementary Regulation of Light Transmittance, Haze, Accumulated Temperature, and Crops The light transmittance, accumulated temperature, and haze of greenhouse anti-reflective glass are closely related to plant growth. They collectively influence the light environment within the greenhouse, thereby regulating photosynthesis, morphogenesis, and yield and quality of plants. Understanding the relationship between these four factors allows for a clearer understanding of the operating principles of greenhouses. 1. Light Transmittance and Plant Growth Light transmittance is a key indicator of the ability of greenhouse covering materials to allow light to pass through, directly affecting the energy supply for plant photosynthesis. The light transmittance of glass greenhouses is typically between 91.5% and 97.5%. Too low a light transmittance leads to insufficient light, inhibiting plant growth; while too high a light transmittance (such as in summer) may cause excessively high temperatures, leading to excessive vegetative growth. Therefore, selecting high-transmittance, non-drip specialized greenhouse glass and regularly cleaning and maintaining it are fundamental to ensuring efficient light utilization. 2. The Regulatory Role of Accumulated Temperature Accumulated temperature (effective accumulated temperature) is the total heat required for plant growth and development, directly related to light intensity and temperature within the greenhouse.
