Responses Of Peanut (Arachis Hypogaea L) Nutrient Content And Translocation To Foliar Spraying Ethrel

In order to solve the ecological environment problems such as the more invalid flowers, the less podss in the growth progress of peanut (Arachis hypogaca L), a field experiment was conducted in2012-2013, used the Xiang Hua2008as the experimental material, try to determine the comprehensive influence on the Peanut biomass, the accumulation and translocation of nutrient elements by foliage spraying ethrel at two growth stages of peanut, The results are as follows:(1) the changes of peanut biomass:The per plant of pod yield was significantly improved by spraying200and500mg/L ethrel at young fruit stage.Unilateral considering for peanut high yield, therefore, this article suggested spraying ethrel optimal concentration:200-500mg/L, the best spraying period:young fruit period.(2) Nutritive element content:The N、P、K、Ca contents were reduced by foliage spraying ethrel at the full-flower stage, spraying ethrel at both full-flower and young fruit stage increased the Fe、Mn、Zn、Cu、Mo contents.(3)Nutrient accumulation:Foliage spraying ethrel (500、800mg/L) at the full-flower stage and the young fruit stage increased the Ca、Mg、Fe、Mn、Zn、Mo accumulation of leaves, stem and pods.(4) Nutrients translocation rate:The influence on peanut nutrient transport are diffferent between two spraying ethrel periods, spraying ethre at the full-flower stage can improve nutrient transport rate from Podding stage to maturity.(5) Peanut crops, soil nutrient and the ecological environment:The ecological environment of peanut nutrients is changed by Foliage spraying ethrel at the two stages of peanut growth progress. The ethrel can lead to the plant premature senility, spraying ethrel at the later stages of peanut growth progress increase the absorption of nutrients of peanut but cause the soil environment damaged; spraying ethrel at the earlier stages of peanut growth progress can protect the soil nutrients environment even reduce the pod yield of peanut. So we suggested that use the Compound fertilizer(contents N、P、K、Ca) and Foliage spraying ethrel at the earlier stages of peanut growth progress at the same time to implementation the increase production and maintain the soil nutrients environment.
