摘要
对5种不同间作模式(魔芋、玉米、烤烟、马铃薯、不间作)的早实核桃幼林地进行调查研究。结果表明:间作作物对早实核桃幼林地径和枝梢数有极显著影响,对保存率、树高、冠幅、挂果率有显著影响。最优间作模式为魔芋和马铃薯,其次是烤烟,最差的间作模式为玉米。间作作物高度过高,对早实核桃幼林冠幅、枝梢数、挂果率有抑制作用。
The growth of early bearing young wal nut intercropped with four different plants including konjak, corn, tobacco, potato were studied, compared with the growth of non-intercroppingones. The result showed that the pattern of intercropping had significant effect on ground diameter and branch number as well as preservation ratio, tree heights, tree crown and fruiting rate. The growth of early bearing young walnut intercropped with konjak and potato was the best, tobacco followed and corn the worst. The over-height of intercropping plants would inhabit the tree crown, branch number and fruiting rate of early bearing young walnut.
