摘　　要：越冬菠菜(唐山大叶)新鲜茎叶产量在92544kg/hm2水平下,平均每生产1000kg新鲜茎叶,植株需吸收Ca0.848kg,Mg0.561kg,S0.411kg,比例为1.00∶0.66∶0.48;3月2日～4月10日是植株吸收Ca,Mg,S的主要时期,分别占各自总吸收量的72.91%,62.74%,72.65%;收获时,植株吸收的Ca,Mg,S主要贮存在绿叶中。Under the situation that the yield of fresh stems and leaves of the overwintering spinach (Tangshan Daye) was 92 544 kg/hm^2, to produce every 1 000kg fresh stems and leaves, 0.848 kg Ca, 0.561 kg Mg and 0.441 kg S should be absorbed by the plants. The absorbing proportion of Ca, Mg and S was 1.00∶0.66∶0.48. Ca, Mg and S were mainly absorbed from March 2nd to April 10th by the plants, which were 72.91%, 62.74% and 72.65% of their total value of absorption. At the harvest time, Ca, Mg and S that were absorbed by the plants were mainly stored in green leaves.
