| 原文摘要 | The disposal of non-compostable plastic has caused plastic pollution in every corner of the world. Along with agriculture, the demand for plastic for agricultural purposes is increasing. This non-compostable plastic will not only affect the environment but also in human life. In recent years, people have increased their awareness of the environment, along with the demand for eco-friendly products that pose no threat to the environment. The purpose of this study is to test whether biochar pot is a suitable growing environment for corn nursery in order to minimalize or even substitute the usage of plastic pot. Biochar acquired from gasification will undergo inhibition assessment using corn as a target crop. After that, pot was made with a mixture of peat moss and starch with an equal amount. Peat moss was subject to the replacement with different ratios of biochar (5%, 10%, 15%, and 100%) and to make the biochar-pot. The corn also will undergo a water-deficit stress test with the biochar pot. The result showed no significant difference in corn growth during biochar inhibition assessment. However, soil with biochar application has increased its properties such as pH, EC, water holding capacity, and soil organic matter. The results of the peat moss replacement experiment showed that corn shoot dry weight was increased in the replacement ratio of 100% biochar. In the water-deficit test, biochar of 100% and 15% have the highest shoot fresh-weight, and there was a significant increase in shoot dry-weight with biochar of 100%. The overall findings revealed that biochar pot is suitable as a growth pot for corn seedling without inhibiting its growth. |
