缩节安(DPC)对花生荚果产量及籽仁品质的影响

在大田栽培条件下,研究了花生不同生育时期叶面喷施 DPC 对产量和品质的影响。结果表明:在结荚后期施用 DPC 可显著增加荚果产量,表现为饱果率提高,果重增加。DPC 可提高花生籽仁中氨基酸含量,对蛋氨酸含景的提高效果尤为明显,提高31.3%～43.8%,同时对籽仁中粗蛋白、粗脂肪及糖分的含量电有增加的趋势。

EFFECTS OF DPC ON POD YIELD AND KERNNEL QUALITY OF PEANUTS(Arachis hypogaea L.)

Under conditions of field cultivation,the effects of foliar-spraying DPC on yield and quality of peanuts were studied.The results indicated that DPC could increase pod yield through higher mature fruit percentage and pod weight. And DPC could increase amino acid content,especially methionine which was increased from 31.3% to 43.8%.Also there was increasing tendency for crude protein,crude fat and total sugar content.
