Abstract:The influences of basic fertilizer and topdressing fertilizer percentage of N on the yield of rice in low-middle producing farmland in Ningxia irrigation region were studied.The results showed that: the highest rice yield was at 13 436.5 kg/hm2 with the application of 65% basic fertilizer and 35% as topdressing fertilizer for transplanted rice;while with the application of 50% basic fertilizer and 50% as topdressing fertilizer,the rice yield was at 12 957.0 kg/hm2.For direct seeding rice,the highest rice yield was 7 403.0 kg/hm2 with the application of 50% as basic fertilizer and 50% as topdressing fertilizer,while with the application of 65% as basic fertilizer and 35% as topdressing fertilize,the rice yield was at 7 253.5 kg/hm2.
Keywords:rice  low-middle producing farmland  N fertilizer percentage of basic-fertilizing and topdressing
