The invention provides a foam matrix for planting dracaena sanderiana and a preparation method thereof.The foam matrix is prepared from, by weight, 3-5 parts of polyurethane A material, 1-2 parts of polyurethane B material, 0-10 parts of rural soil, 0-10 parts of coco coir, 0-10 parts of turfy soil and 5-6 parts of water.The foam matrix is prepared by compounding polyurethane foam with the rural soil, the coco coir, the turfy soil and the like; the foam substrate for planting the dracaena sanderiana is prepared. The foam substrate disclosed by the invention has good water absorption, water retention and air permeability, so that the growth environment of roots of crops is improved, the growth of seedlings is promoted, and a theoretical basis and a technical support are provided for substrate improvement and indoor planting of dracaena sanderiana seedlings.

The invention relates to an ecological control device for river pollution, which comprises a box body, two vertical sieve plates are arranged in the box body and divide the box body into a water inlet cavity, a purification cavity and a water outlet cavity; the water pump is used for pumping water in a river channel into the water inlet cavity; the plurality of electrode plates with holes are arranged in the purification cavity and divide the purification cavity into a plurality of carbon cavities filled with activated carbon; positive and negative electrodes of the electrode plates are alternately arranged at intervals; the aperture of the sieve plate is smaller than that of activated carbon; the transparent and closed glass bin is arranged at the upper end of the box body; the dracaena sanderiana is arranged in the glass bin, and the root system is located in the carbon cavity; the light source is arranged at the top of the glass bin and emits red light and blue light downwards; and the floating block is arranged on the outer side of the box body. According to the device, the plants are full of nutrients through a method of firstly enriching and then growing the plants, rapid growth of the plants is promoted through electrode voltage, photosynthesis of the plants is promoted through blue light and red light, and the dracaena sanderiana rapidly grows.

The ceramic artware comprises a ceramic base, a limiting mechanism and an adjusting mechanism, a groove is formed in the ceramic base, a supporting plate is fixedly installed in the middle of the groove, a ceramic sleeve bottle is installed at the top of the supporting plate, the adjusting mechanism is fixedly installed in the ceramic sleeve bottle, and the limiting mechanism is fixedly installed in the ceramic sleeve bottle. A limiting mechanism is fixedly mounted at the bottom of the ceramic sleeve bottle; the limiting mechanism comprises an inserting block, a limiting groove is formed in the inserting block, a limiting block is installed in the limiting groove, a spring is fixedly installed on the right side of the limiting block, a circular groove is formed in the inner bottom of the inserting block, a cross rod is fixedly installed in the circular groove, and the adjusting mechanism comprises a ceramic inner bottle. An external thread is fixedly installed on the outer portion of the ceramic inner bottle, and the external thread of the external thread is connected with an internal thread. The ceramic handicraft capable of cultivating dracaena sanderiana has the effects of conveniently changing water and adjusting the height of the ceramic bottle.
