Abstract
The dynamics of growth and yield structure of rice were studied in a cold paddy field of China under shallow water-intermittent irrigation(SIT),moisture-intermittent irrigation(MIT)and continuous flooding irrigation(CSF).The results showed that compared with CSF treatment,SIT and MIT treatments were beneficial for the formation of low and thick straw of rice,which would enhance the lodging resistance of rice.During the whole growth process,the leaf area indexes of rice under different irrigation treatments were in the order of MITSITCSF,and the difference was the most significant in the mid and late tilling stages.Compared to CSF treatment,spike dry weight and effective panicles per plant under SIT and MIT treatments significantly increased,the aboveground biomass of rice increased 7.0% and 9.5%respectively,and the actual yields of rice were improved by 8.6%and 11.9%respectively.SIT and MIT irrigation modes provide the way to solve the problem of low production of well irrigation rice in cold region of China.
