Abstract

The purposes of this research were to understand the number of pruning and
harvest residues of 7 major crops in Kaohsiung and Pingtung, and to test the

application of different biochar in crop production. The results of the survey
showed that 7 major crops in Kaohsiung and Pingtung, with approximately

137,491 tons/year of pruning or harvest residues. If collected effectively, about
5,925-7,109 tons/year of biochar with carbon sink function can be produced. In

addition, different biochars were used to conduct field trials on adzuki bean and
Chenopodium formosanum. According to the test results: 1. In the production and

application of adzuki bean crops, the use of biochar made from rice husks to
improve soil can slow down the impact of sodium on crops. After the

experimental treatment, the harvest yield was significantly higher than the control
group. Among them, high-temperature biochar (rice husk ash biochar) +

phosphorus solubilizing bacteria fertilizer had the best harvest yield. Each
