【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%.
