摘　　要：０．１～１００ｍｇ·Ｌ－１Ｌａ（ＮＯ３）３均能促进小球藻的异养生长，有助于葡萄糖的利用。异养培养时间≤３６ｈ时，Ｌａ３＋显著抑制小球藻对ＮＯ－３的吸收，之后则加速ＮＯ－３的吸收。Ｌａ３＋还能提高小球藻的叶绿素ａ、叶绿素ｂ及总叶绿素含量，最大促进百分率分别为２３．４％、２７．１％及２４．７％。In the heterotrophic culture,La(NO3)3 at the concentration from 01mgL-1 to 100mgL-1 could slightly stimulate the growth of chiorella and was beneficial for chlorella uptaking glucose.La3+ could increased the contents of chlorophyll a,chlorophyll b and the total chlorophyll in chlorrella by 234%,271% and 247%,respectively
