厨余垃圾堆肥液浓度比对白菜生长高度的影响探究

厨余垃圾的随意乱扔,不仅污染环境,还间接危害人体健康,有效利用厨余垃圾是解决环境问题的一项重要难题。为了减少厨余垃圾的丢弃,利用厨余垃圾可堆肥特点来进行堆肥,并探究不同浓度比的堆肥液对白菜生长高度影响,以相同土壤配置的原土作为实验基质培育白菜,检测白菜性状的变化指标。就本实验的结果表明,浓度比低,不会使得白菜枯萎死亡,只是减缓其生长速率;浓度比过高,会抑制处于幼苗期的白菜生长,在浓度比达到50∶700有最佳效果。因此选择合适堆肥液浓度比可显著促进白菜的生长。

The random littering of kitchen waste not only pollutes the environment,but also indirectly endangers human health.The effective use of food waste is an important problem to solve environmental problems.In order to reduce the disposal of kitchen waste,the composting characteristics of kitchen waste were used to compost,and the effect of different concentration ratio of composting solution on the growth height of Chinese cabbage was studied.The original soil with the same soil configuration was used as the experimental substrate to cultivate cabbage.The change index of the character of Chinese cabbage was detected.The results of this experiment show that the lower the concentration ratio is,it will not make the cabbage wither or die but slow down its growth rate;if the concentration ratio is too high,it will inhibit the Chinese cabbage in the seedling stage,and the best effect will be achieved when the concentration ratio reaches 50∶700.Therefore,choosing the appropriate ratio of composting solution can significantly promote the growth of Chinese cabbage.
