EFFECTS OF APPLYING THE USED BAGASSE SUBSTRATE OF SHIITAKE CULTIVATION TO SUGARCANE FIELD ON THE CANE GROWTH AND THE SOIL ECOLOGY

Bagasse, one of by-products from sugar mill, has been used as principal ingredient of the substrate for artificial cultivation of shiitake (Lentinus edodes) recent years in some sugarcane growing areas of China. The effects of the used bagasse substrate on soil ecological environment and sugarcane plant growth were investigated in 1987/1988. The results show that by applying the used bagasse substrate to sugarcane field, the soil structural properties were improved, the amounts of the soil beneficial unrobes increased, the activities of soil enzymes raised and the soil effective nutrients enhanced. A higher vitality and a longer nutrient uptakeperiod of the sugarcane root system were observed as well under the case of treatment with the used bagasse substrate. As a result, improvement of plant growth and cane yield were achieved.
