摘　　要：为校正张家界慈利县测土配方施肥参数且优化肥料配方,客观评价其施肥效益,于2021年在慈利县开展了中稻玉珍香测土配方施肥肥效校正试验。结果表明,与常规施肥相比,配方施肥有效穗数、穗总粒数和千粒重分别增加3.77%、7.69%、10.36%,产量增加349.5 kg/hm^(2),产值增加964.62元/hm^(2);与不施肥对照相比,配方施肥有效穗数、穗总粒数和千粒重分别增加6.45%、9.36%、10.86%,产量增加690.0 kg/hm^(2),产值增加1904.40元/hm^(2)。因此,测土配方施肥可满足水稻的生长发育需求,有明显的增产增收作用,值得在慈利县中稻生产中大力推广。In order to correct soil testing and formulated fertilization parameters and optimize fertilizer formula in Cili County,Zhangjiajie,and objectively evaluate its fertilization benefit,a experiment was conducted in 2021 to correct the fertilizer efficiency of mid-season rice Yuzhenxiang soil testing and formulated fertilization in Cili County.The results showed that,compared with conventional fertilization,formulated and fertilization increased the effective number of panicles,total number of grains per panicle,and 1000-grain weight by 3.77%,7.69%,and 10.36%,respectively,increased the yield by 349.5 kg/hm^(2),and increased the output value by 964.62 yuan/hm^(2).Compared with the control group without fertilization,the formulated fertilization increased the effective number of panicles,total number of grains per panicle,and 1000-grain weight by 6.45%,9.36%,and 10.86%,respectively,increased the yield by 690.0 kg/hm^(2) and increased the output value by 1904.40 yuan/hm^(2).Therefore,soil testing and formulated fertilization can meet the growth and development needs of rice,with obvious effects on increasing yield and income.It is worth vigorously promoting in the mid-seasonriceproduction of Cili County.
