水稻测土配方施肥示范试验效果评价

通过对水稻配方施肥示范试验,在水稻的产量、效益上与常规施肥进行对比,从增产率、增收、产投比等指标对配方肥效果进行评价。结果表明,配方施肥较常规施肥对第一作业区、第二作业区、第四作业区、第六作业区、第七作业区的水稻增产、增收效果更好,产投比增幅也较大;而对第三作业区、第五作业区、第八作业区、第十作业区、科技园区的水稻有增产作用,但不增收。

Evaluation on the Experiment of Soil Testing and Formulated Fertilization on Rice

The yield,benefit were compared between soil testing and formulated fertilization and conventional fertilizer to evaluate the effect on yield rate,increment and the ratio of outputs to inputs of soil testing and formulated fertilization,the results indicated that the 1st,2nd,4th,6th and 7th work areas can achieve better yield and benefit and more the ratio of outputs to inputs,but at the 3rd,5th,8th,10th and technology park can increase the yield without increased profits.
