测土配方施肥对佛冈县水稻栽培的影响

         

摘要

[目的]探讨配方施肥对佛冈县水稻生产的影响。[方法]以广东省佛冈县汤塘镇为试验地点,通过田间试验,研究了配方施肥和常规施肥对水稻产量、养分吸收、肥料利用率和经济效益的影响。[结果]配方施肥处理产量达7014.3 kg/hm 2,较常规施肥增产14.22%,较空白对照增产46.82%;净收益较常规处理增加了3497.7元/hm 2,较空白对照增加了7267.2元/hm 2;肥料利用率较常规施肥提高了19.36个百分点。[结论]初步确定佛冈县合理的水稻施肥配方为 N∶P2 O5∶K2 O =9.6∶2.4∶7.2。%Objective] The aim was to discuss effects of formula fertilization on rice production in Fogang County.[Method] With Tangtang Town, Fogang County in Guangdong Province as test site, through field experimemt, effects of formula fertilization and conventional fertiliza-tion on rice yield, nutrient absorption, fertilizer utilization rate and economic benefits were studied.[Result] The result showed that yield of formula fertilization was 7 014.3 kg /hm 2 , increasing 14.22% than conventional fertilization and 46.82% than blank control; net profit was increased 3 497.7 yuan /hm 2 compared with conventional fertilization and 7 267.2 yuan /hm 2 than blank control, the fertilizer use efficiency of formula fertilization was 19.36% higher than conventional fertilization.[Conclusion] The reasonable formula fertilization of rice was N∶P2 O5∶K2 O =9.6∶2.4∶7.2 in Fogang County.
