The classification system of backbone forest strip types had been put forward according to the landform type,strong or weak sea wind,microtopography,forest tree growth,forest strip structure feature and windproof efficacy by means of the typical survey of backbone forest strips for \%Casuarina equisetifolia\% in the coastal draught,the mobile observation of windproof efficacy and the serial researches of regeneration afforestation technigues on Chishan Forest Farm,Dongshan County and Chihu Forest Farm,Hui′an...

The classification system of backbone forest strip types had been put forward according to the landform type,strong or weak sea wind,microtopography,forest tree growth,forest strip structure feature and windproof efficacy by means of the typical survey of backbone forest strips for \%Casuarina equisetifolia\% in the coastal draught,the mobile observation of windproof efficacy and the serial researches of regeneration afforestation technigues on Chishan Forest Farm,Dongshan County and Chihu Forest Farm,Hui′an County both in Fujian Province since 1992.The local forest belts were classified into 9 main types and the backbone forest strip classification regeneration theory was advanced accordingly.The breakthrough of backbone forest strip classification theory research brought along the constant innovation in the forest strip regeneration modes and afforestation techniques and energetically promoted the smooth development of backbone forest strip regeneration afforestation in \%C.equisetifolia.\%In respect of forest strip regeneration modes,according to the different\|type forest strip regeneration afforestation research result,the alternate strip and planting under canopy within strips and the thinning interplanting regeneration mode were put forward,as well as various key techniques,including regeneration strip width control,crown density control and thinning intensity were adopted. Based on the combinative principle of tree species adaptability,fast growth and protective function,some regeneration afforestation tree species were raised for different\|type forest strips,such as \%Acacia crassicarpa,A.aulacocarpa,Eucalyptus ABL No.12, Pinus elliottii\% and \%C.equisetifolia\% excellent clones.More than 7 million plants of these excellent tree species and clones had been bred and were popularized for afforestation in the adjacent cities and counties in succession.In respect of key techniques for forest strip regeneration afforestation,the serial drought\|resistant afforestation techniques of digging deep holes for site preparation,putting into the proper earth removed from other places,applying phosphoric fertilizer,mixing mud,selecting rainy days for afforestation in spring,planting deeply with big container\|growing seedlings,and ridging tending for preserving the soil moisture in young forests were put forward for the poor habitat conditions of gales,drought,soil being deficient water and poor,etc.in autumn and winter,and the planting survival percent of most tree species reached 90% or so.The average height of main planting tree species of 3\|year\|old young forests was 3~5m,which had become closed forests and began to give full play to protection.Thus the relative wind speed within regeneration forest strips was about 10% less than that before planting.This is one of the great breakthroughs of regeneration technique researches of backbone forest strips for \%C.equisetifolia\% in the coastal draught.These techniques have been accepted and universally adopted by the local forestry productive units.
