The Primary Experiment on Artificial Promote Recovery of Wild Hazel
In order to explore the rapid recovery path and natural regeneration rule of wild hazel hazel,the Hazel bush Finer tillering and Biological renewal characteristics of wild hazel hazel were studied by means of soil loosening,burrows digging,impurity removal,density adjustment and artificial enclosure.The results show that Artificial promotion measures can accelerate the recovery and expansion of wild hazel,Compared with the control,the radial extension distance of hazel bush roots could be increased by 42.4% .The density of 5.7 plants/m2 increased by 45.2%,followed by 2.9 plants/m2(43.3% )and 8.8 plants/m2(38.6% ).However,it has little effect on the Biological renewal and the regularity is not strong;The law of natural regeneration of wild hazelnut bush is the spatial regeneration characteristic of dense regeneration area of seedling with the radius of Mouse activity of 20～30 m.The correlation coefficient R2=0.915 was consistent with the model of Y=0.694 4X3-9.881 X2+39.139 X-28,the relationship between the number of new plants and the distance from the hazel bush,which revealed the mechanism of natural regeneration of wild hazel in a cluster pattern.
