摘要
用DA-6,聚天门冬氨酸钾,复硝酚钠不同比例复配出三种叶面肥在花生的不同生长期喷洒,喷洒质量浓度为2g/L和3.4g/L。结果表明:不同配方叶面肥可以提高花生的产量,与空白对照相比,产量提高5%~9.4%。三种叶面肥在花生产量、干物质积累以及叶绿素含量等方面存在差异,根据差异确定出三种叶面肥使用的最优浓度以及具体的使用效果。
Three kinds of foliar fertilizers were sprayed with different concentrations of DA-6,Poly aspartate potassium and Sodium nitrophenolate at different growth stages of peanut.The spraying concentrations were 2 g/L and 3.4 g/L.The results obtained were listed as follows,the application of different foliar fertilizer could increase peanut yield 5%~9.4% higher than that of blank control.There were different in peanut yield,dry matter accumulation and chlorophyll content of the peanut,the optimal concentration and the specific use effect was determined according to the difference.
