| 摘 要： | 我国三北地区大面积农田防护林网主要为杨树林网，树种单一，容易造成病虫害蔓延。但由多树种组成的混交林网由于树种生长速度不同，造成树木群体生长参差不齐，而导致某些树木受压抑而不能正常生长甚至死亡，从而降低了林带的防护效益。为改变这一现状并建立起一整套混交...

| Abstract: | The poplar is a main tree species of the farm shelterbelt in Northeast
China. This farm shelterbelt with single tree species is easily caused plant diseases and insect
pests . The mixed plantation usually result in restricting normal growth of some trees owing to
different growth speed. The object of the experiment is poplar and elm mixed shelterbelt. Three
mixed patterns and three dosage of nitrogenous fertilization were selected in the mediating
growth experiment. The results showed that fitable afforestation pattern of poplar and elm
mixed shelternet and rational nitrogenous fertilization dose could enhance elm growth, that was
restricted because of the slow growth of young trees.The study provided the guide for the
rational afforestation and management of poplar and elm mixed plantation. |
