Early rice recommends OPT processing to increase 19kg K based on the potash fertilizer of straw-returning2O/ha, and it is (average compared to fertilization compositions based on earth measurement ST
For 84kg K2O/ha) only subtract and apply 5kg K2O/ha.Each testing site peasant habit amount of potassium applied range in Jiangxi is 80~236kg K2O/
Ha, average dose are up to 180kg K2O/ha, much larger than the result 72kg K based on the method2O/ha and fertilization compositions based on earth measurement
As a result 12kg K2O/ha, can Potassium Fertilizer, which obtain efficiently utilizing, needs to be verified in next step.
Although the Potassium Fertilizer that OPT processing in Hunan Province is recommended is increased substantially compared to FP processing, same amount of increase in production
It is also obvious that the early rice yield of OPT processing reaches 6852kg/ha, (5425kg/ha) is handled compared to FP, volume increase ratio reaches
26.3%, specifically refer to table 5:
