白酒糟循环流化床燃烧灰直接肥料化利用

研究了白酒糟循环流化床燃烧灰直接作为肥料的可能性和效果，以其为肥料种植油菜，考察了油菜在5种土壤中发芽和生长情况. 结果表明，白酒糟燃烧灰对不同生长阶段的油菜有不同影响，对壤质土中的油菜发芽有抑制作用，但能明显改善粘性土壤中油菜的生长环境，油菜的净增量和产量都有明显增加. 白酒糟燃烧灰还能提高酸性土壤pH值，使土壤环境向中性(pH 6.97~7.74)转变，有利于腐殖酸分解和植物生长. 土壤与白酒糟燃烧灰质量比为5:1时，与原土相比，泸州国窖红土壤、泸州青稞土壤及富阳土壤中油菜净增量分别为80.1%, 80.9%, 163.6%，表明利用白酒糟燃烧灰作为植物生长肥料是可行的.

Direct Utilization of Circulating Fluidized Bed Combustion Ash of Distilled Spirits Lees as Fertilizer

The feasibility of utilizing the circulating fluidized bed combustion ash of distilled spirits lees as fertilizer was investigated. The rape culture experiment was carried out in 5 different kinds of soils, and the rape growth states in the germination and growth stages were measured to evaluate the effect of adding ash to the soils as fertilizer. The results show that the ash exhibited different effects on the rape growth in different culture stages. There was an antiblastic effect on the rape growth in the germination stage in a loamy soil, but the rape growth was much improved when adding the ash to a clayey soil. The latter led the mature rape to having obviously increased net height and weight. The ash could change the pH value of acid soil into neutral state, facilitating the humic acid decomposition and plant growth. Comparing the soils at soil:ash=5:1(w) with original soil, the increased amplitudes of net height of rape in Guojiaohong Turang, Qingke Turang and Fuyang Turang were 80.1%, 80.9% and 163.6%, respectively. As consequence, it was feasible and effective to use directly the combustion ash of distilled spirits lees as fertilizer.
