红松、日本落叶松与色赤杨、白桦等阔叶树种混交造林技术的研究

Mixed planting techniques by Pinus koraiensis, Larix leptolepis with Alnus tinctoria and Betula platyphylla

红松、日本落叶松与色赤杨、白桦混交造林 ,直径生长量比纯林提高 3%～ 15 % ,树高比纯林提高 5 %～ 95 % ,材积比纯林提高 18%～ 99%。

The research results of mixed planting with Pinus koraiensis,Larlix leptolepis and Alnus tinctoria,Betula platyphylla show that:compared with pure stants,the radial incnement increased by 3～15%;longitudinal increment increased by 5～95% and increased by 18～99% in volume gowth.
