摘要
在乌泥田对水稻进行测土配方施肥试验,结果表明:测土配方施肥可有效增加水稻穗实粒数、丛有效穗数;在比习惯施肥减少肥料投入成本36.4%的情况下,每667 m2较习惯施肥增产148.2 kg,增收353.7元。
A trim of soil test and formula fertilization was carried out in dark paddy soils. The results showed that the formula fertilization could effectively improve the filled grain number per ear and the effective panicles number per hill; in the condi- tion of decreasing the fertilizer costs less 36.4% than that of conventional fertilization, the yield and income were per 667 m2 148.2 kg（2223 kg/hm2 ） and 353.7 RMB Yuan（5305.5 RMB Yuan/hm2 ） higher than that of conventional fertilization re- spectively.
