摘要
为了解马铃薯在实施水肥一体化条件下的肥料利用率,2018年在商都县以马铃薯兴佳2号为供试材料,设置习惯施肥区和水肥一体化施肥区对比试验。结果表明:马铃薯水肥一体化全肥区比当地农民习惯施肥全肥区产量提高了2 493 kg/hm^2,增幅为9.07%;马铃薯在实施水肥一体化条件下,氮、磷、钾肥料利用率比习惯施肥分别提高了8.9,8.5,7.0百分点,说明实施水肥一体化能显著提高马铃薯的产量和肥料利用率。
To understand the fertilizer requirement of potatoes in Shangdu under the conditions of fertilization technology,we designed a comparative experiment of potato fertilization methods.“Xingjia No.2”was used as test material,and we explicated the method of conventional and utilization in this test.The results show that,the yield of potato with fertilizer increased by 2 493 kg/hm2,an increase of 9.07%.Compared with conventional fertilization,the method of utilization increased the efficiency of nitrogen,phosphorus and potassium by 8.9%,8.5%and 7.0%,respectively.It indicated that the implementation of fertigation could significantly improve the yield and fertilizer ratio of potato.
