西藏柏木(CuPressus torulosa Don),又名喜马拉雅柏,原产喜马拉雅山西部,属柏科柏木属.1977年我圃引入少量种子育苗,1979定植培育,1984年9月测查树高已达5.48米,胸径达10.8厘米.为了进一步摸索西藏柏木在我地区的表现情况,1983年又从西藏引进种子进行播种育苗试验,现将情况简述如下.引种地的自然条件引种地位于北纬32°11′,东经119°28′,地处宁镇丘陵东端.土壤为下蜀系黄土母质发育而成的死黄土,PH4.9,有机质含量1.85%,速效磷含量21.6PPm;表土层厚度12厘米,土壤溶重1.24克/厘米~3,地下水位1米以下.据丹徒县气象站资料:1983年年平均气温15.2℃,最高气温37.8℃,最低气温-7.7℃;年降雨量1016.1毫米(?)年蒸发量1279.7毫米;晚霜期3月9日,初霜期11月13日,无霜期249天.
CuPressus torulosa Don, also known as the Himalayas, is native to the western part of the Himalayas and belongs to the genus Cypress. In 1977, we introduced a small amount of seedling nurseries. In 1979, we planted the nursery. In September 1984, the tree height reached 5.48 meters , Chest diameter of 10.8 cm.In order to further explore the performance of Tibet cedar in my area, in 1983 and from Tibet to introduce seeds for seedling nursery trials, the situation is summarized as follows.Down to the natural conditions of the introduction of the location at latitude 32 ° 11 ’ , Longitude 119 ° 28’E, is located in the eastern end of Ningzhen hills.The loess soil loess is loess, PH4.9, organic matter content 1.85%, available phosphorus content 21.6PPm; surface layer thickness of 12 cm, According to the data of Dantu County Meteorological Station, the annual mean temperature in 1983 was 15.2 ℃, the highest temperature was 37.8 ℃, the lowest temperature was -7.7 ℃, and the annual rainfall was 1016.1 mm (? ) Annual evaporation 1279.7 mm; late frost March 9, the first frost period November 13, frost-free period 249 days.
