采用完全随机区组试验设计,研究了河北平山片麻岩石质山区不同组合的翼式鱼鳞坑结合集水保墒处理对黄栌幼树林地水分以及黄栌光合速率和生长指标的影响。结果表明:1)集水保墒措施最高可使降水后土壤含水量较对照提高66.76%;2)施加集水保墒措施可使黄栌光合速率较对照提高16.54%~56.48%;3)集水保墒处理可分别显著提高黄栌地径及新梢生长量80.28%~102.82%和17.52%~76.96%,而防渗克漏王+保水剂+石块覆盖(F+B+S)处理则可提高材积生长量578.04%;4)综合考虑,防渗克漏王+保水剂+石块覆盖(F+B+S)、防渗克漏王+秸杆覆盖(F+J)、防渗克漏王+石块覆盖(F+S)、自然坡面+保水剂+秸杆覆盖(Z+B+J)为该区域栽植黄栌较好的集水保墒措施。

In order to select appropriate water collecting and soil moisture conserving measures for Cotinus coggygria Scop.young plantation in gneiss mountainous area of Pingshan county,Hebei province,the comparison of 10 treatments and 1 control teatment is made with the design of completely randomized blocks.The soil water content,net photosynthetic rate,chlorophyll content,ground diameter,height,volume and shoot length were used to indicate the effect of different measures on Cotinus coggygria Scop.The result showed that:(1)soil moisture could be at most improved by water collecting and soil conservation measures for 66.76% in a rainfall cycle;(2)the net photosynthetic rate of the trees increased by 16.54% to 56.48%;(3)the growth of trees such as ground diameter and shoot length could be enhaced through the above CK by 80.28% to 102.82% and 17.52% to 76.96%,and the treatment F+B+S(spraying nanomaterial leakproof + soil absorbent polymers + stone mulching)enhaced the volume by 578.04%;(4)considering the factors above,F+B+J,F+J(spraying nanomaterial leakproof +straw mulching),F+S(spraying nanomaterial leakproof+ stone mulching)and Z+J(natural slope +straw mulching)were recommend as the available measures for Cotinus coggygria Scop.in gneiss mountainous area.
