黄连木在石灰岩山地造林适宜性的研究

为研究黄连木在石灰岩山地的造林适宜性，选用麻栎、新银合欢、樱桃、冲天柏作对照进行造林试验，结果表明：黄连木苗高生长量最大，地径生长量略低于冲天柏，但高于麻栎、新银合欢和樱桃；黄连木造林后2年的保存率高于其他4个树种．黄连木在各地生长状况和保存率均良好，在石灰岩山地造林具有较强的适宜性，适合在同类地区推广．

A Study on the Adaptability of Afforestation of Pistacia chinensis in Limestone Mountainous Areas

In order to study the afforestation adaptability of Pistacia chinensis in limestone mountainous areas,the authors selected Quercus acutissima,Leacaena leuacephala,Cerasus pseudocerasus and Cupressus duclouxiana as contrast samples.The results have showed that the seedling height of Pistacia chinensis has the biggest growth. However,its land diameter growth rate is lower than that of Cupressus duclouxiana but higher than that of Quercus accutissima,Leacaena leuacephala,and Cerasus pseudocrasus,the conservation rate of Pistacia chinensis is higher than that of the other 4 species.The growing condition and conservation rate of Pistacia chinensis are all good,and its afforestation adaptability in limestone mountainous areas is good too,thus it can be widely developed in the similar geological areas.
