Abstract

The invention discloses a grit matrix cleaning device and relates to the technical field of sand culture. The grit matrix cleaning device comprises a bracket, a driving device and a filter box. The bracket is movably connected to a stirring container, a stirring shaft is arranged in the stirring container, stirring blades are arranged on the stirring shaft, the top of the stirring container is opened, and a movable screen is arranged on the top opening of the stirring container; the driving device is arranged on the bracket, and the output end of the driving device is connected to one end of the stirring shaft; the filter box comprises a first box body and a second box body, the first box body can be placed in the second box body, and a water outlet hole is formed in the side wall of the first box body. The invention also discloses a grit matrix cleaning method of the grit matrix cleaning device. According to the grit matrix cleaning device and the grit matrix cleaning method, large grit can be removed and soluble nutrients attached to the surface are cleaned, so that a cleaned grit soil matrix meets demands on scientific research tests such as nutrient stress and grade size uniformity of a culture matrix, and therefore, the scientific research efficiency is increased greatly.

Description

technical field [0001] The invention relates to the technical field of sand culture, in particular to a sand and gravel matrix cleaning device and method. Background technique [0002] Sand culture is a kind of soilless cultivation. Generally, river sand is used as a growth substrate to supply nutrient solution in the form of drip irrigation for crop growth. The sand and gravel for sand cultivation should be in the range of 0.5-3.0 mm in size. Sand cultivation has been widely used in indoor pot experiments in agriculture and forestry because of its easy-to-obtain substrate and low production cost. The gravel matrix should be sieved before use to remove large gravels; at the same time, the gravel matrix should be washed before use to remove the soluble nutrients attached to the surface of the gravel, so that the gravel matrix meets the scientific research requirements of nutrient stress and medium particle size uniformity . The gravel matrix in the existing simulation tests...
