石灰岩山地黄连木造林技术研究

Study on Forestation Techniques of Pistacia Chinensis Bunge in Limestone Mountainous Area

运用3因素5水平2次正交旋转组合试验方法研究了石灰岩山地春季造林中保水剂、ABT生根粉和基肥3项辅助造林措施对黄连木造林成活率和新植幼树生长量的影响。结果表明:3项辅助措施对造林成活率的影响均达到显著或极显著水平,但对幼树生长量的影响较小。3项措施中,对成活率的绝对影响是保水剂>基肥>ABT生根粉;对苗木生长量的绝对影响是基肥>保水剂>ABT生根粉;3项辅助措施间的交互作用不显著。

Effect of three supplementary forestation measures on survival rate of forestation and growth of newly planted saplings were studied applying quadratic orthogonal rotation combination of three factors and five levels. The results showed that effect of three supplementary forestation measures on survival rate of forestation were significant, but less on growth of newly planted saplings. Absolute effect on survival rate was aquasorb 〉 basal fertilizer 〉 ABT rooting powder ; and saplings growth was basal fertilizer 〉 aquasorb 〉 ABT rooting powder ; interaction among three supplementary forestation measures was insignificant.
