Plant compatible ecological concrete and application thereof

The invention provides plant compatible ecological concrete and application thereof. The concrete is prepared by the following steps: (1) mixing and stirring volcanic rock with the particle size of 10-18 mm, volcanic rock with the particle size of 20-30 mm, ordinary Portland cement, a nutrient material and water, and pouring and curing to prepare the concrete; the treating fluid is sprayed into the concrete, so that the treating fluid fully permeates into concrete gaps, and the concrete is placed for at least one day; the treating fluid is prepared from tetraethoxysilane, sodium tetraborate, sodium metaaluminate, ammonium hydroxide and water according to the mass ratio of (2-3): (0.5-1): (0.5-1): (0.5-1): 20. The concrete provided by the invention has a continuous gap structure, provides a necessary space for the growth of plants, is beneficial for the plants to quickly absorb water and nutrients, and promotes the growth of the plants. Meanwhile, the method can also reduce the influence of saline-alkaline sub
