Abstract

An experiment was carried out to explore suitable fertilization model for rice quantitative cultivation in the northern area of Liaoning by comparing the application effects of three kinds proportion of nitrogen fertilization to the conventional fertilization. The results showed that the nitrogen divided as 6∶4 by basal fertilizer and panicle fertilizer is relatively reasonable, which can effectively control the ineffective tillers, increase grain numbers per spike, seed setting rate and the weight of grain, increase yield by 18.6%.
