红松结实分杈是生理自然现象 ,分杈要有相等或相近对称同轮侧枝条件。通过各林龄当年轮生侧枝相等或相近对称枝组发生株率 ,认定 3 5年生以上人工红松林可作截头 ,促进杈干培育多主轴结实枝 ,其中 2 5 %～ 3 0 %强竞争枝要在截头时同时剪去才能促进结实并丰产 Korean pine bough is a natural physiological phenomenon, bifurcation should be equal or similar symmetrical same round of collateral conditions. According to the plant strains of the same or similar symmetrical shoots in each age of the rotation, it was found that the artificial pine forests above 35 years old could be used as truncated to promote the cultivation of multi-spindle strong shoots, of which 25% ~ 30% were highly competitive Branches cut at the same time in the truncated to promote strong and productive
