粗砂濾泥蔗渣髓製作堆肥栽培洋菇之研究

Studies on the Utilization of Filter Cake of Raw Sugar and Bagasse Pith as Compost of Mushroom

粗砂濾泥為製造糖工廠之副產物，年產十萬公噸，其中含有大量之蔗渣。蔗渣隨為利用蔗渣製作紙漿工場廢棄物，臺糖公司年產量估計約十四萬噸。比二物質均含有豐富有機物，未能充份利用，蔗渣髓更為工場不易處理之廢物。經適當處理後，不需堆積酸酵可直接栽培洋菇，且產量可與稻草堆肥比美，為最經濟之洋菇栽培材料。

Filter cake of raw sugar and bagasse pith were by-products of sugar and paper factory respectively The above materials have no economic value, but they are the compost of plant fiber in higher level Whether those material can serve as a compost of mushroom instead of rice straw were studied in our station from 1970 to 1971. 1. Mushroom, which growed in the fresh filter-cake containing raw sugar after peak heating without any fertilizers, was quite well. Ste productivity was 17% higher than that of rice straw compost but decreased 33% while it was storaged in the open field through summer season. The difference between filter cake and rice straw compost was not over the level of significance 2 Yield of bagasse pith mixed with half rice straw and composted straw through 21 days increased 72.2%, but the single bagasse pith decreased 15.7% as compared with the rice straw compost. 8. Whether bagasse pith mixed with half rice straw, half filter cake of raw sugar or 6% of organic manure (2% wheat bran, 2% rice fine bran and 2% soy bean meal was directed through peak heating. Yields of those treatments were decreased 23.9-24.8% as compared with rice straw compost treatment but the difference was not significant. According to the primary results of this study, we find that the filter cake of raw sugar or bagasse pith can be used as a compost of mushroom and could be made mechanically The cost of mushroom will be decreased by using this worthless material as a substitute for rice straw compost. This subject will be further studied because the amount and quanlity of fertilizers of bagasse pith compost are unknown.
