有机无机肥配施改善辽西北风沙区花生氮素积累、产量及品质
Combined application of organic and inorganic fertilizers improve N accumulation,yield,and quality of peanut in the wind sand area of Northwestern Liaoning
摘要
Abstract
For high-yield and high-quality peanut cultivation in Northwestern Liaoning,field experiments were carried out in windy sandy area of Northwestern Liaoning Province.Effects of combine application of organic and inorganic fertilizers were investigated on growth,nitrogen accumulation,yield and quality of peanut in windy and sandy soil in 2021 and 2022.Controlled by no fertilizer treatment,3 treatments were designed and tested as in-organic fertilizers(N)alone,organic fertilizers(O)alone,and combined application of organic fertilizers and inorgan-ic fertilizers(N+O).Plant traits included plant height,leaf area index,dry matter accumulation,nitrogen accumula-tion,yield and quality of peanut.The 3 treatments as N+O,N,and O had significantly higher plant height than CK in the middle growth stage,and N+O had significantly higher plant height than CK throughout the whole growth stag-es.At the flowering and pod filling stages,the N+O treatment had 7.3%and 15.8%(2021),and 14.6%and 13.4%(2022)higher dry matter accumulation than the N treatment,respectively.At the pod setting and pod filling stages,the N+O treatment had 10.2%and 15.8%(2021),and 19.6%and 13.4%(2022)higher total nitrogen accumulation than the N treatment,respectively,and at the pod filling stage,the pod nitrogen accumulation of the N+O treatment was 17.4%(2021)and 16.9%(2022)higher than the N treatment,respectively.In 2021,pod yield,kernel yield,and 100 kernel mass of N+O treatment were 14.1%,10.5%and 9.1%higher than N,respectively.In 2022,N+O treat-ment had 2.4%higher protein content than N treatment.In conclusion,combined application of organic fertilizers and inorganic fertilizers treatments increased peanut plant height,leaf area index,dry matter accumulation,and to-tal N accumulation,which ultimately increased peanut yield and improved peanut quality.关键词
