土体有机重构技术在黄河滩地项目上的应用表明:重构后耕作层水分入渗速率为11.84cm·d~(-1),相比原始状态的沙土降低了89%,相比原始状态的黄土降低了86%;重构后土体有机质、全氮、有效磷、速效钾含量均处于丰富水平,相比沙土分别增加了1.06倍、2.07倍、8.54倍和1.23倍;以容重为1.7g·cm~(-3)的黄土构建5cm厚人造犁底层,以容重为1.2g·cm~(-3)的黄土构建25cm厚耕作层效果最佳。
The application of soil organic reconstruction technology to the Yellow River beach project shows that the water infiltration rate of reconstructed tillage layer is 11.84cm · d -1, which is 89% lower than that of the original sandy soil. Compared with the original state The content of organic matter, total nitrogen, available phosphorus and available potassium in soil were all at a high level, which were 1.06 times, 2.07 times, 8.54 times and 1.23 times higher than those of sandy soil respectively after reconstitution; g cm ~ (-3) loess to construct a 5cm thick artificial plow bottom layer, and the best 25cm thick tillage layer was constructed with loess with a capacity of 1.2g · cm ~ (-3).
