Abstract

Abstract: 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.

Key words: Potato;Fertilization technology;Fertilizer utilization ratio
