Abstract

Abstract: To know the best wheat tillage method in no irrigation and Shajiang black soil condition, a field positioning test is used under five tillage treatments, including straw returned conventional and repression (PCR), no straw returned deep scarification and repression (ASR), no straw returned rotary tillage and repression (ARR), no straw returned rotary tillage (AR), no straw returned compound drill (ACP). The results showed that the highestPn andTr were found in ARR treatment with 26.54 μmol/(m2·s) and 10.53 μmol/(m2·s), 11.17 mmol/(m2·s) and 3.84 mmol/(m2·s) in wheat flowering and 20 days after flowering. TheSPAD of ARR was in the second place among different tillage treatments in 10 days after flowering. ARR treatment had the highest protein content, wet gluten content, sedimentation value and hardness. Therefore, ARR treatment is recommended as the most appropriate tillage treatment for promoting photosynthetic characteristics, dry matter and filling rate of wheat in Huaibei area of Anhui Province, and plays a positive role in achieving high yield.
