Abstract:Adopting the orthogonal-gyrating-regress design,5 factors in the culture of high quality super rice variety ’Jijing 88’ were studied.The results showed that:(1)’Jijing 88’ could produce high and steady crop,the average yield was 9 101.4 kg/hm2.If it was properly cultivated,the highest yield of 1 1269.1 kg/hm2 can be reached.(2) The order of effect of cultural factors on the yield of ’Jijing 88’ was: Nitrogen application>the way of rice seedling transplant>Phosphorus application>number of rice seedling transplanted>Potassium application.Among these factors,Nitrogen application is the most important to yield.(3) If the yield of’Jijing 88’ reaches over 10 000 kg/hm2,it must be cultivated in such ways as follows: 220~228.0 kg/hm2 of Nitrogen,102.0~111.5 kg/hm2 of Phosphorus and 28.5~38.7 kg/hm2 of Potassium applied,rice seedling transplanted at density of 30×13.6~14.8 cm,5.1~5.8 seedlings per hold.
