| Abstract: | Study result:the technical scheme of each hectare output of direct brodcast rice that more than 7 500 kg in draw yellow irrigation district of north of Ningxia is , per hectare use 45 000 kg organic fertilizer, broadcast quantity is 333-375 kg, use pure N 259.5-280.5 kg, use P2O5 120-136.5 kg; On the field piece of medium fertility, each hectare output of direct brodcast rice reaches over 8 250 kg,the technology scheme is:on the basis of uses organic fat 4 500 kg/ hm2 ,broadcast quantity is 301.5-340.5 kg/hm2, use pure N 268.5-289.5 kg/hm2, use P2O5 79.5-90 kg/hm2. |
