根は「ストレス」で強くなる。赤玉土と軽石の本当の役割【植物生理学】

Even with expensive fertilizer, why aren't your plants growing well? The reason might not be nutrient deficiency, but rather "physical malnutrition." Pre-order information for the BOTANICS grow light is at the bottom of the description. In this issue of and Plants, we focus on the "physics" of the soil. When plant roots encounter obstacles such as stones in the soil, they open calcium ion channels and generate electrical signals in just 1 to 10 seconds. Obstacles are not "walls that inhibit growth" for roots, but rather "dumbbells (resistance)" that help create stronger, more muscular roots. Why do roots branch at such a precise angle of "32.5 degrees"? What is the perfect soil structure created by akadama soil (micro-water reservoir) and pumice (macro-ventilation tunnel)? And even the magical mechanism by which microorganisms break down iron rust and deliver it to plants. Based on the latest "plant physiology," not on anecdotal evidence or rules of thumb, we deliver insights that will dramatically improve your plants. __ 【BOTANICS LED Pre-orders Now Open】 Light designed with data for plants.
