【Abstract】 The key techniqure to improve the survival and growth of Pinus tabulaeformis on dry south sides in lower rocky mountain in North China is to keep water for raising soil moisture. As a soil preperation measure, the large fish scale-like holes with inclination to slope,and mulching them with plastic film or grass have the advantages to increase soil temperature in early spring and to maintain a higher soil moisture. This may create the suitable ecological conditions in the micro onviornment for the plants to survive and grow.更多还原
