| 摘 要： | 双氰胺渣是化工厂生产双氰胺过程的剩余物。本试验利用双氰胺废渣对衰败低产毛竹林进行施肥,采用3种施肥处理试验结果表明:每公顷施渣肥1125kg加复合肥225kg,年增鲜笋57.6％,新竹增产101.4％;单施渣肥2250kg/hm~2,年增鲜笋49.3％,新竹增产102.8％。单施渣肥成本低,经济效益好,年增收入381元/hm~2,说明利用双氰胺废渣改造毛竹低产林,既增产增收又避免环境污染,变废为宝,具有重要的开发利用价值。

| Abstract: | Experiment on application of dreg from dicyandiamide produc-
tion to low yield bamboo stand with three treatments showed that annual increase of fresh bamboo shoot and new bamboo output was 57.6% and 101.4% respectively by applying 1125kg dregs and 225 kg compound fertilizer per hectare, if applying 2250 kg dregs per hectare, annual increase of fresh bamboo, shoot and new bamboo output was 49.3% and 102.8% respectively. Therefore, the cost of applying dregs was low, the economic benefit was better and an-nual increase of income was 3810 yuan/hm2. |
