Abstract:
By analysis of temperature distribution character and rate of selffertilization of Themosensitive Genic Male Sterile (TGMS) rice with low sterile temperature,it is concluded that the beginning day and the last day of the suitable cold waterirrigated for Peiai 64S is the eighteenth day and the third day before panicles headed day ,respectively.The irrigation depth in the first ten days is 15cm,and 20cm in the last five days,which provides theoretical base for the practical production of multiplying with cold waterirrigated.
