【摘要】 通过对兴安落叶松不同苗床高度换床及不同土壤解冻深度换床的苗木生长与地温、气温等主要气象因子关系的研究，找出兴安落叶松换床的最佳苗床高度及最佳、适宜土壤解冻深度。更多还原

【Abstract】 hrough the study of the relationship between the seedings growth of the Larix-gmelini and the meteorological elements (soil-temperature, air temperature et al.), the best seedling-bed highness and the best moderate soil-defreezed depth for the Larix-gmelini plant are found. Therefore a theoretical and scientific basis is developed.更多还原
