摘　　要：采用田间试验方法,研究了在施氮量相同的条件下,有机肥和无机肥不同配施比例对苋菜的根系特性,产量及品质的影响。结果表明:在施有机氮20%时,苋菜的根系活力最高,且苋菜品质较好;在施有机氮10%时,苋菜的产量最高。The effects of different ratios of combined application of organic and mineral fertilizers on root characteristics, yield and quality of amaranth were studied with the same nitrogen fertilizer rate by field experiment. The results indicated that when organic nitrogen was 20%, the root activity of amaranth was the highest and the quality was relatively great; when organic nitrogen was 10%, the yield of amaranth was the highest.
