26. 1992 : Started Conservation Tillage research with ACIAR Projects Results: With No till Seeders developed by CTRC , answered: Is CA practicable in China? How to do CA ? What are the benefits of CA? Can we use machines to do CA in China?
48. Conventional Tillage ( 11.30g/m 2 ) produced more CO 2 emission than Rotary till ( 9.63g/m 2 ) and No-till ( 7.99g/m 2 ) for the whole year. 传统耕作 11.30g/m2 , 比旋耕 9.63g/m2 和免耕 7.99g/m2
