章古台沙地樟子松嫁接红松技术的研究

Study on Introduction of Pinus koraiensis Grafted by Pinus sylvestris var. mongolica on Sand Land of Zhanggutai

利用樟子松作砧木,以红松作接穗,改变了红松对立地条件要求较高的生物学特性,扩大了红松的栽培范围。试验表明:在章古台沙地经嫁接的红松生长发育良好,并正常开花结实,径生长量为樟子松的117.8%,材积为146.38%,其木材产值是樟子松的4.4倍。

Biological characteristic of demanding better site conditions of Pinus koraiensis was changed and its cultivation range was extended by using Pinus koraieasis to be scion, taking Pinus sylvestris var. mongolica as rootstocks on sand land of Zhanggutai. The grafts grow and develope well, and produce cones and seeds. They are 117.8 % bigger in diameter, 146.38 % larger in volume and 4.4 times higher in wood value than Pinus sylvestris var. mongolica.
