Path Analysis of the Effect of Planting Hole Control Body on Salt Content in Seashore Saline Soil

Abstract:

Soil column experiments were conducted to study the effects of planting hole control body (PHCB) on the salt content using a hybrid uniformity design U12(12×43×34) on different soil condition (the groundwater mineralization, soil texture, the supplementary water). The planting hole control body (PHCB) was made of 4 kinds of components (local arbor, bagging material, filling material and its thickness, membrane material). For the components above and the soil condition, the method of path coefficient analysis was used to identify the major factors and to quantify the influencing degree. The results show that the supplementary water, soil texture, membrane material, local arbor, bagging material and filling material and its thickness were remarkably influential factors, and their path coefficients were statistically significant. The order of influence on the total salt content is local arbor, soil texture, membrane material, bagging material,filling material and its thickness, the supplementary water. The direct path coefficient of soil texture and local arbor display higher value, the former is 0.816, the latter is 0.994. Especialy, local arbor has less influence with small correlation coefficient (-0.027), which indicate that the interaction among various factors played a more important role. In a word, applying PHCB to reduce the salt concentration is an effective method.
