摘 要:针对太行山低山丘陵区土壤干旱瘠薄,水土流失严重,造林成活率低的特点,开展了以保水节水为中心的抗旱造林及水分管理技术研究。通过6种抗旱造林技术试验,筛选出优化造林技术模式,可使造林成活率达96%以上;确定了野生酸枣Ziziphusjujubavar.spinosa嫁接大枣Z.jujubavar.inermis的最佳嫁接方式、嫁接时间和管理技术;提出有灌溉条件和无灌溉条件下复合农林业系统水分优化管理技术;提出的果农复合系统开沟断根结合肥料深施技术,可使土壤含水量提高30%,苹果Maluspumila产量提高28%;筛选出细长纺锤形为果农复合系统苹果树最佳树形。According to the characteristics of dry and barren soil, severe soil erosion, low survival rate of planted forests in the hilly region of Taihang Mountains, studies on technologies of drought-resistant afforestation and moisture management were conducted. The results showed that: (1) From 6 experiments of techniques for drought-resistant afforestation, the optimum model was selected,the survival rate of which was more than 96%.(2) The suitable method and time of grafting between wild spine date and Chinese data (Ziziphus jujuba var.inermis) were determined.(3) Two kinds of the optimum moisture management models for agroforestry systems in lands with or without irrigation system were put forward.(4) A new fertilize application technique for apple (Malus pumila) and crops intercropping systems, combined with ditching, root pruning and fertilize deep placement, could increase soil water moisture by 30% and increase fruit yields by 28%.(5) The optimum shape of crown of apple tree in the intercropping system was slender spindle.
