| Abstract: | Combining technology transfer and independent,the new technology system of rice directly sowing was formed.Its core techniques were：early and mid-maturing varieties of resistant to cold,oxygen agent seed coating,mechanical dry seeding,fertilizer on the side,early irrigation,etc.The results showed that selecting Longjing No.8 varieties,applying oxygen coated,sowing date on the May 6th～13th,sowing 100.0～112.5 kg·hm-2at depth 5～20 mm,the yield could arrive at more than 7 500 kg·hm-2.Their beard performance：emergence number was 300～310 plant·m-2,panicles number were 550~600 spike·m-2,grain number per panicle was 58~62 grain,the total grain number was 33 thousand grain·m-2 or more,maturity 82%～90%,grain weight was 24～25 g. |
