The Effects of Iron Fertilizer Application on Yield and Fe Concent of Grains in Mung Bean
Mung bean,as an important food-medicine homologous crop,has a low yield per unit area.Applying iron fertilizer can improve the photosynthesis of mung bean plants and further improve its yield and quality.In this study,two application modes of iron fertilizer(basal application,B1;80％basal application+20％spraying,B2)were set in field with four application amounts of iron fertilizer(0,250,500,750 kg/ha,represented by CK,A1,A2,A3,respectively).The effects of different treatments on photosynthesis parameters,yield and its related indexes and iron content of grains were studied.The results showed that compared with CK,the chlorophyll content,chlorophyll fluorescence parameters,yield-related indexes(plant height,pod length,pod number per plant,100-grains weight,grain yield,biological yield)and grain Fe content of mung bean were significantly increased with A3 treatment.Compared with Bl mode,the actual photochemical efficiency[Y(Ⅱ)],photosynthetic electron transport rate(ETR)and grain Fe content were significantly affected by the B2 mode.Therefore,this study concluded that 750 kg/ha iron fertilizer combined with 80％base application+20％spray application could significantly improve the yield and grain quality of mung bean.
