毛竹伐桩快速腐烂技术试验研究

Research on Experiment of Fast Rotten Technology on Bamboo Stake

竹伐桩在自然状态下腐烂速度极度缓慢 ,为加快其腐烂速度 ,增加土地有效利用空间 ,试用尿素、碳酸氢铵、食盐、草甘磷等肥料或农药 ,木霉、果胶霉等生物菌类单种或组合施于竹桩内腔。结果表明 :这些物质都能有效提高竹桩腐烂速度 ,但提高速度有差别。使用草甘磷与碳酸氢铵、食盐的混合处理是本试验中农药和化肥组合中的最佳组合 ,它在处理后 2年可达到自然状态的 6年 ,腐烂速度提高了 3倍。单用果胶霉、木霉处理腐烂速度也可以提高 3倍 ;毛竹桩先加入碳酸氢铵后覆土 ,再加入一定量的果胶霉、木霉 ,其处理后 2 3个月竹桩的腐烂程度相当于自然状态下的 6年程度 ,腐烂速度可提高 3倍以上。

In the nature, bamboo stake is rotten slowly. In order to improve its rotten speed and add more available space, try to put some fertilizers such as u rea and salt, and biological bacterial manure, for example, some agricultural ch emical, wood mold and pectin mold to the center of the bamboo culm. The results show that these materials can raise the rotten speed, but not the same. If peopl e put salt and some other fertilizers together, the rotten speed will three time more than before. Only add pectin mold to wood mold, the effect is the same as the former one.
