Abstract: Shanlan upland rice was cultivated under three patterns:paddy,rice-straw mulching and upland to determine their drought-tolerant physiological parameters,agronomic traits and yield components in the field trial.The results showed that the paddy cultivation alleviated drought stress on Shanlan upland rice,reduced the contents of POD,MDA and soluble protein and increased the chlorophyll content of the flag leaves.Rice straw mulching had similar,although less,effect to the paddy cultivation.Compared with the conventional upland cultivation,the paddy and rice straw mulching cultivation increased the plant height of Shanlan upland rice by 30.62% and 16.69%,the flag leaf length by 14.32% and 6.62%,the available? tillers by 64.7% and 26.47% and the yield by 267.44% and 91.04%,and shortened the growth stage by 12 and 5 days,respectively.Under paddy field conditions Shanlan upland rice has many advantages such as lower drought stress,optimal agronomic traits and higher yield.This study may provide a scientific basis for further research on cultivation pattern of Shanlan upland rice shifting from traditional upland to paddy field.
