造纸污泥在竹林基地上的肥效研究

Research on Fertilizer Effectiveness of Paper Sludge Applied in Bamboo Base

在对污泥所含有机质等理化成分进行分析的基础上,以造纸污泥作为有机肥,对比分析了不同施肥处理对竹林生长的影响。结果表明,施用污泥可使竹林的发笋时间提前,比施用无机竹肥平均提前15天,比不施肥平均提前了25天;施用污泥有利于竹子的生长,其中专用竹肥掺混污泥对竹子生长有明显的促进作用;污泥中含有的养分及大量有机质,对改良土壤结构、增加土壤肥力,促进竹子良好生长效果明显。

To reduce the environmental impact and disposition cost, and to investigate the utilization of paper sludge. After analyzed the physicochemical contents （such as organics） in the sludge, composted sludge was applied to bamboo base. The growth of bamboos under different treatments was compared. The results showed （1） the generation time of bamboo shoots of sludge treated bamboos was earlier than those treated with inorganic fertilizer and CK, 15 and 25 days, in average, respectively. （2） Sludge is better for bamboo growing. Mixture of fertilizer and sludge increased bamboo growing. Among the treatments, mixture of fertilizer and sludge treated bamboos grew the best, and sludge treated only bamboo also grew much better than CK.（3） The nutrients and massive organics in the sludge improved soil texture, increased soil fertility and facilitated bamboo growing.
