1974年以来,我们在陇县八渡林场,对153亩4000多株油松砧木,连续数年进行嫁接。平均成活率一般都在76%以上,部分小区嫁接成活率高达97%。结合生产还开展了不同嫁接时期、不同嫁接方法、不同嫁接部位、接穗的不同处理、嫁接苗的不同管理等项试验。现将油松嫁接技术总结如下。 Since 1974, we have grafted on more than 4000-acre pine rootstocks in 153 mu in Ba Duo Forest Farm in Long County for several years. The average survival rate is generally above 76%, some areas of graft survival rate as high as 97%. In combination with the production of different grafting period, different grafting methods, different grafting sites, different treatment of scion, different management of grafted seedlings and other tests. Now Pinus sylvestris grafting techniques are summarized below.
