摘要:
 通过U12（2×35）均匀试验设计方法，建立以耐盐树种、覆膜材料比、果胶含量、填料种类、填料厚度和填料布设方式为因子的树木植穴结构控制（PHCC）基本单元，探究其在盐渍土环境下对穴内外土壤全盐量的控制程度与因果关系。结果表明，PHCC各因素在0~40 cm的深度范围内对穴内全盐量的影响次序为填料种类>填料厚度>耐盐树种>覆膜材料比>果胶含量>填料布设方式；对穴外则为耐盐树种>覆膜材料比>填料厚度>果胶含量>填料布设方式>填料种类；当确定最佳PHCC组合为火炬树种，PVA∶PAM比5∶5，0.1%果胶含量，填料加草炭+牛粪，厚度7 cm，底部+周围布设时，可使穴内0~40 cm土层全盐量比对照组低(88.86±5.65)%，穴外全盐量比试验前原土降低(45.6±2.38)% 。
Abstract:
 Through the methodology of uniform experimental design U12(2×35),a basic unit of planting hole composition control (PHCC) was established based on examining relative factors to explore their degrees of controlling over total salt content inside and outside the hole in saline soil as well as their causal relationships.The results showed that in the depth of 0-40 cm soil layer,the influence order of the impacts of the factors on total salt content inside the hole was types of filler>thickness of filler>salt-tolerant tree species>ratio of film mulching>pectin content>emplacing manners,while outside the hole,the order was salt-tolerant tree species> ratio of film mulching> thickness of filler>pectin content types> emplacing manners> types of filler.When the salt-tolerant tree species was Rhus typhina,other factors were PVA∶PAM,5∶5; pectin content,0.1%; filler types,peat and cow dung; the thickness of filter,7 cm.When the filters were emplaced on the bottom and around,the salt content was (88.86±5.65)% less than the control group inside the hole,and outside the hole,the salt content reduced (45.6±2.38)% compared to the control soil.
