Abstract：In order to research the suitable seeding method for high -yielding cultivation of drought see-ding rice,taking Koshihikari as material,3 treatments,CK (narrow drilling),T1 (wide drilling)and T2 (so-wing after surface rotary tilling),were designed by randomized block arrangement in the field.The results showed that wide drilling could make the seedling emergence rate stable,the population be in tidy,the indi-viduals be strong,and increase the spike number,grain number per spike and 1 000 -grain weight.The yield of wide drilling was 6 593.1 kg/hm2 ,which increased by 16.1% and had very significant difference with that of narrow drilling.Sowing after surface rotary tilling had a low seedling emergence rate,no full stand,no tidy population,large difference of individuals.However,the average grain number and 1 000 -grain weight in-creased.The yield was 6 281.8 kg/hm2 ,which increased by 10.6% than that of narrow sowing with very sig-nificant difference.Narrow drilling,whose seeds were distributed concentratedly in a line,could make the seedling emergence rate stable and population be in tidy.But its individuals were weak,so the grain number per spike and 1 000 -grain weight dropped.
