不同间种模式对核桃树体生长量的影响

Effect of Different Intercropping Modes on Growth Increment of Juglans sigillata

以8年生漾濞大泡核桃幼林为研究对象,研究了芋头、辣椒、玉米、茶叶4种间种作物对核桃树体(地径、树高、冠幅、新梢长、新梢粗)生长量的影响。结果表明:不同间种模式能不同程度促进核桃树体的生长发育,尤其间种芋头显著增加了核桃树体生长量,是山区核桃林地最佳间种模式。该研究结果为探讨适合云南核桃林地的最佳间种模式及山区核桃高效栽培技术的组装集成提供了理论参考依据。

Taking 8-year-old J uglans sigillata as research object,four intercropping experiments of J. sigillata with taro, pepper,corn and tea were conducted,and cleaning tillage was set as the control. The growth increment indexes including basal diameter, height, crown width, length of new shoot, diameter of new shoot of J. sigillata were measured and analyzed. The results showed that under the management of intercropping, the growth and development of J. sigiUata trees were improved to different extend, among which intereropping with taro significantly increased the growth increment of J. sigillata. This research provided some information and basis for exploring the optimum intercropping modes of J. sigillata and for efficient J. sigillata cultivation in mountainous areas of Yunnan Province.
