摘要
通过对夏玉米常规施肥和配方施肥的氮、磷、钾肥利用率试验,结果表明配方施肥区比常规施肥区每公顷增产574kg,增产率6.61%;配方施肥区氮、磷、钾肥的利用率分别比常规施肥区氮、磷、钾肥高6.24%、4.68%和16.51%。相对常规施肥,配方施肥明显提高氮、磷、钾肥的利用率,在农业生产上,应注重推荐氮磷钾比例协调的配方肥,改变农民施肥的习惯,才能提高氮、磷、钾肥的利用率。
Fromthe experiment of nitrogen,phosphorus and potassium utilization of summer maize was carried out.The results showed that the yield per hectare increased by 574 kg and the yield increased by6.61%;The utilization rates of N,P and K in the formula fertilization area were 6.24%,4.68%and 16.51%higher than those in the conventional fertilization area.Compared with conventional fertilization,formula fertilization significantly increased the utilization rate of N、P、K fertilizer,In agricultural production,attention should be paid to recommending formula fertilizers with a coordinated ratio of nitrogen,phosphorus and potassium,and changing farmers’fertilization habits in order to increase the utilization rate of nitrogen,phosphorus and potassium fertilizers.
