Effects of application of lignin on the growth and yield of spring maize

摘要: 试验研究施用木质素对春玉米生长发育及产量的影响结果表明，施用木质素可促进春玉米对N、P的吸收，提高肥料利用率，减少肥料污染和提高作物品质，有显著增产作用，且不同处理春玉米增产率均≥20％。

Abstract: The effects of application of lignin on the growth and yield of spring maize are studied．The results show that the application of lignin can promote the absorption of N and P in maize，increase the efficiency of fertilizer，decrease the fertilizer pollution，improve the crop’S quality，and increase the maize yield．The increased yield rates of different treatments attain or exceed 20％．
