Abstract
In this paper,nitrogen amount and ways of applying scattered transplanting rice were studied.The results indicated as follows:with the increase of nitrogen quantity,the amount of maximum tillers and effective panicle increased;among three distributes of nitrogen,maximum tillers and effective panicles of B 1 and B 3 were more than those of B 2.RGR and CGR were higher under middle level of nitrogen and a collocation of early,middle and late fertilizer application,but NAR was higher under low nitrogen level.The number of primary branch did not basically change with nitrogen quantity and distribute;under low and middle level of nitrogen,the number of secondary branch was almost the same in total differentiation number,extant number and regressive number,but under the condition of high nitrogen level there were more 3 4 secondary branches and 2 3 secondary retrogressing branches.N level and collocation had no effect on spikelets per panicle and 1000 grain weight.Under the condition of this experiment,135 165kg/ha nitrogen quantity was reasonable in scattered transplanting cultivation.According to mean yield,top dressing at later growth stage was necessary and it was relation to the level of nitrogen application.
