With the fertilizer applied, rice yield can be improved by 292.5-505.5 kg/hm2, with increase of 6.63%-10.92%; farmer’s incomes can be enhanced by 877.5-1 516.5 yuan/hm2, with net income growth of 783-1 422 yuan; output-to-input rate kept in 8.29-15.05. The increased rice yield is mainly contributed by the in-creases of setting percentage and thousand-seed weight, of which the former＇s role is more significant. Hence, the fertilizer can be widely applied in Lichuan and similar regions.展开更多
