Abstract
In order to verify the effects of mechanical direct-sowing and irrigation mode on rice root system characteristics and yield, the experiments of involving both mechanical direct-sowing modes and irrigation modes, such as water direct-sowing and conventional flooding mode(WF), water direct-sowing and and intermittent irrigation mode(WSW), dryland directsowing and conventional flooding mode(DF) and dryland direct-sowing and and intermittent irrigation mode(DSW) to compare with conventional transplanting and flooding irrigation(CK) were conducted in 2013 and in 2014, respectively, some rice paremeters, such as root system characteristics and yield were investigated. The results indicated that, in 2013, the actual yield of WF and WSW were increased by 7.3% and 5.3% than CK, respectively, but yield difference was not significant between dryland direct-sowing treatments and CK; the changed tendency of the actual yields was roughly same in 2014 as those in 2013. Mechanical direct-sowing mode and irrigation mode was good for rice roots extend and improved root activity,dryland direct-sowing mode could postpone leaf senility of the leaves in rice later stage of growth, which was condutive to saving-water in the case of increase or no significant cut yield.
