A super high yield experiment of rice was carried out on saline-alkali land development experimental area of Daan ancient river channel using ’Jijin 88’,a super rice variety of non-salinity.The results showed that the yield was 10768.2 kg/ha in 7.33 hectares,which was 7.5% higher than that of ’Jijing 503’ and 30.5% higher than the average of rice production on the Songneng Plain,so it became a new record of rice unit yield in the plain.The key technique included: reducing the saline of soil to critical value of the non-saline soil used drip washing,transplanting rice proper earlier to extend the growth period and planting closely to get more ears,applying formula fertilizer and plus manure to supply enough nitrogen,irrigating by shallow-deep-shallow-wet mode.This experiment extended the cultural range of ’Jijin 88’ and broke non-alkali limit.Different types of soda saline-alkali soil can be developed to grown rice,even super-high-yield can be achieved.This is of important economic and social significance to enhance the regional rice yield and construct food production base.
