This study analyzed the key environmental factors affecting the summer survival rate of Larix kaempferi grafted seedlings to inform seed orchard establishment and management. Based on an 80% survival rate, we selected a superior region (Chuncheon, Gangwon Province) and an inferior region (Cheongju, Chungcheongbuk Province) and measured the environmental factors, including air and soil temperature, humidity, and wind speed, from July to September. Simultaneously, we analyzed the physical and chemical properties of the soil in both regions. Statistical analyses, including t-tests, correlation analyses, and mediation analyses, revealed that soil temperature, wind speed, and soil hardness had significant negative effects on the survival rate of Larix kaempferi grafted seedlings. Soil temperature was identified as a direct negative factor, while wind speed and soil hardness were indirect negative factors on the survival rate. The Chuncheon site, characterized by relatively lower temperatures, higher humidity, softer soils, and better nutrient conditions, was more conducive to seedling survival. In contrast, the Cheongju site is characterized by hot and dry conditions, leading to harder soil, which hindered seedling establishment. These findings suggest that lowering soil temperature, effectively mitigating strong winds, and improving soil physical properties are crucial strategies for enhancing the summer survival of Larix kaempferi grafted seedlings. Furthermore, a comprehensive consideration of various environmental factors will help develop efficient establishment and management approaches for Larix kaempferi seed orchards.
