The invention discloses houses for breeding silkworms with living folium mori, row clipping cocooning frames and a method and relates to rearing instruments and a new method which is to directly arrange a plurality of houses in a mulberry field, lift the expansion rods (6) according to weather move the houses with silkworms, move the house (11) for breeding silkworms with living folium mori every four days, breed silkworms in the grids of the row clipping cocooning frames (19), which is provided with protrusions (16), clamping grooves (17) and grid layers (18), one by one at regular density and sequence, collect folium mori for silkworms layer by layer and grid by grid and bridge to supply folium mori in turn every three days. The problem of inter-row space for silkworms is solved, the four essential factors including ventilation, cooling and drying, adequate living folium mori and disinfecting for preventing diseases are guaranteed, an economic growth mode is changed, the working time per kilogram of cocoon is reduced to 0.2 hour from 5 hours, which is less than the 1.6 hours in Japan, land productivity and labour productivity are improved considerably, one person can breed 30 boxes of silkworms in a single season, high productivity, high efficiency, high quality, low consumption and labor conservation are achieved, and thus, the houses and the method promote the specialization, intensification, scale-up, industrialization, labor conservation and modernization of the silkworm and mulberry industry.
