| Notes | Tree,filler,membrane material were used to build planting hole control body（ PHCB） for the ＂ desalinized fertile layers＂ in saline soil. The effects of structure factors of the PHCB on soil organic matter were studied to optimize the PHCB and provide theory basis for improving saline soil. The experimental schemes were designed by homogeneous array of U12（ 2 × 35） to investigate the influence of the structure factors on soil organic matter content inside or outside of planting hole. Regression analysis showed with PASW statistics 18 that the correlation was obvious between soil organic matter content and structure factors of PHCB（ R2= 0. 991）. The factors having significant influence on soil organic matter content inside PHCB were in the following order： tree species pectin concentration filler filling thickness mass ratio of PVA / PAM filling position. The significant ordering of the effects on soil organic matter outside PHCB is as following： pectin concentration filling position filler tree species mass ra |
