在蔗区,若能充分利用糖厂在生产过程中排放出的三废(滤泥、糖蜜造酒精废液、蔗渣造纸废液、蔗髓造糠醛废液、锅炉蔗渣灰、煤灰等)以及蔗叶作甘蔗肥源,既可以减少环境污染,又能给甘蔗提供较好的有机质肥,保持或提高土壤肥力,促进甘蔗对养分吸收,以利提高甘蔗产量及蔗糖分,是一项变废为宝、以蔗养蔗、经济有效的废物利用途径。(一)蔗田施用滤泥,可改良土壤性质,促进甘蔗对养分的吸收制糖生产过程中所得的滤泥含有丰富的碳源和作物所需要的氮、磷、钾养分及微量元素,是较好的有机质肥。据分析,其中有机质含量
In the sugarcane area, if we can make full use of the three wastes discharged by the sugar mill in the production process (such as filter liquor, molasses alcohol waste, bagasse papermaking effluent, cane pulp furfural waste liquid, boiler bagasse ash, coal ash, etc.) Leaf as a source of sugarcane, not only can reduce environmental pollution, but also to provide better organic fertilizer to sugar cane to maintain or enhance soil fertility and promote the absorption of nutrients in sugarcane, in order to facilitate the production of sugarcane and sucrose, is a turn waste into Po, sugarcane sugarcane, cost-effective ways to use waste. (A) the use of clay in the sugarcane field can improve soil properties and promote the absorption of nutrients in sugar cane The resulting filter during the production of sugar is rich in carbon sources and crops required for nitrogen, phosphorus and potassium nutrients and trace elements, is Better organic fertilizer. According to the analysis, which organic content
