摘要:The possible nutrient problems existing in leaf etiolation, the influence of film mulching on the yield of peanut and benefits of balanced fertilization were analyzed. The results showed that the deficiency of nutrient elements was not main limiting factor in leaf etiolation of peanut in Hong’an. Deep trench, film mulching, liming and organic manure could be used to prevent leaf etiolation. The film mulching could increase the yield of peanut by improving the rate of germination and seedling, the number of branches and full pod, and it was beneficial to playing the effect of balanced fertilization.
