Spraying water-soluble particles on the crop. 作物に水溶性微粒子を散布した実験

Short Introductions of other papers: /paper/ Komatsuna plants were grown and exposed to ammonium sulfate (((NH4)2SO4), AS) submicron particles for 16 days (22.5 µg m−3 per day) in phytotrons. The amount of particles deposited on the leaf  decreased over time, because AS particles deposited on the leaf deliquesced, allowing ions such as SO42− in the… Continue reading Spraying water-soluble particles on the crop. 作物に水溶性微粒子を散布した実験
