杨树新品种区域化对比试验研究

Comparative Experimental Study on Regionalization of New Fast-growing Poplar Varieties

本文以杨树新品种丰林一号和丰林二号为研究对象,进行了区域化对比试验,结果表明:不同立地条件下,两个杨新品种胸径生长量和年蓄积生长量均高于对照,与对照均差异显著。两个杨新品种在两个立地类型中均有较好的适应性,丰林一号的适应性更为明显。

In this paper, the new varieties of Populus Fenglin No.1 and Fenglin No.2 were used as research objects, the regionalized comparison tests were conducted.The results showed that the growth of DBH and annual accumulation growth of two new varieties of Populus was higher than that of the control under different site conditions, significant differences from the control. Two new poplar varieties hed good adaptability in both site types, the adaptability of Fenglin No. 1 was more obvious.
