Abstract:
Artemisia ordosica biochar has abundant pore structure and huge specific surface area,which is a good water holding material.The effect of Artemisia biochar water retention on the carbonization conditions was studied.Three carbonization conditions (carbonization temperature,carbonization time and heating rate) had been set in this experiment.The anaerobic carbonization was taken on black Artemisia ordosica.The results showed that the higher water absorption rate of biochar and Artemisia were 4 246.6-4 803.3 g?kg-1 and 5 340.3 g?kg-1,respectively,biochar 600 ℃in deionized water and water retention capacity were relatively strong.The determination coefficient of fitting curves was 0.963 4-0.986 2,and the maximum was 0.986 2 in carbonization for 60 minutes,the minimum was 0.938 1 in Artemisia ordosica.Evaporation rate was 0.955-0.996 times and 0.996 times relative to natural sand in the sandy soil,its minimum was presented to carbonized 60 minutes at 600 ℃,and the maximum was appeared in carbonized 5 minutes at 600 ℃.However,the heating rate did not play a decisive role in the water absorption and water retention of biochar.Therefore,water retention properties of biochar mainly depended on the carbonization temperature and time,the water absorption and water retention properties were not consistent and water retention in deionized water and sand was consistent,biochar 600 ℃carbonization 60 minutes was the best choice for improving sandy soil water retention properties.
