摘要
进行水稻测土配方个性化施肥,探讨其对水稻的增产和化肥减量使用上的影响。结果显示:个性化施肥下,水稻产量比常规施肥区增产20.2 kg/667 m^2,节约肥料12.7 kg/667 m^2(折纯),节约成本59.6元/667 m^2,增产带来的收益增加54.5元/667 m^2,合计节本增效114.1元/667 m^2,该示范区120 hm^2,共节本增效20.54万元。
Individualized fertilization is based on the formula created according the result of soil testing. In this study, individualized fertilization was evaluated for its effects of increasing rice yield and reducing the application rate of chemical fertilizer in comparison with conventional fertilization. The results showed that compared with conventional fertilization, individualized fertilization increased rice yield by 20.2 kg/667 m^2 and reduced the application of fertilizer（pure） by 12.7 kg/667 m^2, thus reducing cost by 59.6 Yuan/667 m^2 and increasing economic benefit by 54.5 Yuan/667 m^2. Therefore, individualized fertilization brought a total of 114.1 Yuan/667 m^2 in reducing cost and improving benefit, which led to a total of 205 thousand and 400 Yuan of the increase in cost efficiency in the demonstration planting area of 120 hm^2.
