Effects of Active Humic Acid Fertilizer on the Photosynthetic Characteristics and Yield of Peanut
摘要
Abstract
To clarify the effect of active humic acid fertilizer on the photosynthetic characteristics and yield of peanut,and to promote the efficient utilization of peanut fertilizer and the green and sustainable devel-opment,Shanhua9 was used as the test material,and five treatments were set as follows:active humic acid fertilizer 750 kg/ha(FS100),active humic acid fertilizer 600 kg/ha(FS80),active humic acid fertilizer 525 kg/ha(FS70),ordinary ternary compound fertilizer 750 kg/ha(PS100),no fertilization(CK).Chlorophyll content,leaf area index,net photosynthetic rate and yield related indexes were measured at the maturity stage of peanut.The results show that:Active humic acid fertilizer significantly improved the photosynthetic capaci-ty of peanut leaves.Compared with ordinary ternary compound fertilizer treatment,active humic acid fertilizer treatment significantly increased the leaf area index,chlorophyll content and net photosynthetic rate of peanut.In 2021,the leaf area index,chlorophyll content and net photosynthetic rate of FS80 treatment were increased respectively by 8.3％,18.6％and 18.0％compared to ordinary ternary compound fertilizer treatment.In 2022,the leaf area index,chlorophyll content and net photosynthetic rate of FS80 treatment were respectively in-creased by 6.2％,7.5％,and 12.2％compared to ordinary ternary compound fertilizer treatment.The biologi-cal yield of FS100 and FS80 treatments both increased significantly for two years.The number of pods per plant of FS100 and FS80 treatments increased respectively by 20.8％,13.4％and 17.6％,10.1％compared to ordinary ternary compound fertilizer treatment,and the average pod mass increased respectively by 5.9％,5.3％and 5.2％,4.9％compared to ordinary ternary compound fertilizer treatment.Peanut pod yield increased respectively by 1.3％-13.7％and 2.1％-14.3％compared to ordinary ternary compound fertilizer treatment in two years.In conclusion,active humic acid fertilizer can significantly improve the photosynthetic capacity of peanut leaves at the late growth stage,increase biological yield,and promote the increase of peanut pod yield.Under the conditions of this experiment,reducing the application amount of 20％-30％on the basis of tradition-al fertilization,that is,applying 525-600 kg/ha active humic acid fertilizer,can achieve green and effi-cient production of peanut.关键词
