摘要
Abstract
A field experiment was conducted in hill dryland of Tianshui city to study the effect of fertilization on N、P、K, the potato yield(Y) and N, P, K fertilizer between the regression equation was established in hill dryland of Tianshui city, obtained the optimum fertilization of potato urea was 445.9 kg/hm2, resume phosphate calcium was 108.7 kg/hm2, potassium was 554.4 kg/hm2. At this condition, the potato yield was 24 822 kg/hm2.关键词
