Effects of an integrated dryland tillage and soaking pattern on the reducing substances in rice field and early growth of machine transplanted rice

There were some problems in rice-wheat rotation areas, such as low quality of rice field soil preparation, and the accumulation of reducing substances was not conducive to the early growth of mechanically transplanting rice. We explored the feasibility of applying an integrated dry tillage and soaki...

Summary:There were some problems in rice-wheat rotation areas, such as low quality of rice field soil preparation, and the accumulation of reducing substances was not conducive to the early growth of mechanically transplanting rice. We explored the feasibility of applying an integrated dry tillage and soaking pattern to promote high-quality early growth of machine transplanted rice.The experiment was carried out in the experimental base of Sihong county, Suqian city, Jiangsu province from 2021 to 2022.Three tillage patterns were conducted, namely integrated dryland tillage + soaking pattern（Treatment 1, T1）, dryland rotary tillage + soaking + paddy rotary tillage pattern（Treatment 2, T2）, and soaking + paddy rotary tillage pattern（Treatment 3, T3）. The redox potential of paddy soil, the content of reducing substances in different soil layers, and the root and shoot traits of machine-transplanted rice at early growth stage were determined. The result showed that the soil redox potential of T1 was the highest, which wa
