异砧嫁接红松培育速生用材林

１９６５年针叶树嫁接试验中，红松异砧嫁接获得成功。嫁接亲本组合是以樟子松或赤松为砧木。用红松作接穗。１９７２年应用于培育红松速生用材林。嫁接２０年后，经检验接口愈合正常，受光良好的条件下，异砧嫁接红松材积生长量是对照红松的２．０４倍，并大大增强了对不良环境的适应性，可扩大红松人工林的立地分布和自然地理分布区域，缩短红松培育周期，实现红松林种一步到位，具有显著的经济效益和社会效益。

GRAFTING KOREAN PINE WITH STOCKS OF OTHER TREE SPECIES TO CULTIVATE FAST-GROWING TIMBER FORESTS

Grafting Korean pine( Pinus Koraiensis ) trees with stocks of P. sylvestris or P. densiflora was succeeded in 1965. The grafted Korean pine trees were cultivated as fast-growing timber forests in 1972. Twenty years later, the trees with normally healed wound and abundant sunlight had not only 2.04 times as much volume increment as the control's but greater adaptability to bad environments. Therefore, grafting of Korean pine has enlarged its site and natural geographical distribution, shortened its cultivation period and optimized its characteristics so that this method has significant economic and social benefits.
