Construction method and structure of ecological ridge
The invention discloses a construction method and a structure of an ecological ridge. The method comprises the following steps: S1, carrying out charge analysis on soil: S1-1, soaking a soil sample in deionized water for 20-28 hours, and removing organic matters in the soil sample with H2O2; preparing the sample into Ca < 2 + > colloid; s1-2, measuring the surface charge by adopting a back titration method; s1-3, carrying out soil charge calculation according to the calculation result; s2, crop straw is selected as a raw material, and hydrophobic biochar is prepared; s3, soil and biochar are fully stirred and mixed to be uniform, and a biochar-soil compound raw material of a core-shell structure is prepared; s4, ditches of 20-30 cm are dug up and down on the basis of the field plane, and the ditches are filled with the biochar-soil compound to construct ecological ridges; the ecological ridge structure comprises a ridge body built in a field and a composite filling layer arranged on the side face of the ridge body.
本发明公开了一种生态田埂的构筑方法及其结构，方法包括以下步骤：S1、对土壤进行电荷分析：S1‑1、将土样在去离子水中浸泡20～28h并用H2O2除去土样中的有机质；将样品制成Ca2+质胶体；S1‑2、采用返滴定法测定表面电荷；S1‑3、根据进行土壤电荷计算；S2、选用农作物秸秆为原料，制备得到疏水生物炭；S3、将土壤与生物炭充分搅拌混匀制备得到核‑壳结构的生物炭‑土壤复合物原料；S4、在田地平面的基础上下挖20～30cm的沟渠，将生物炭‑土壤复合物填充在沟渠进行构筑生态田埂；生态田埂结构包括构筑在田地里的田埂主体以及设置在所述田埂主体侧面的复合填充层。
