用磷酸二氢钾和尿素作花生种肥，能显著提高花生幼苗叶片中叶绿素含量，增加叶片厚度和单株叶面积，提高叶片的光合能力，进而加快幼苗干物质积累，对花生幼苗健壮生长有明显的促进作用；种肥还能显著增加花生单株结果数和百果重，进而提高花生产量；从壮苗效果和增产幅度等看，磷酸二氢钾与尿素配施优于单施磷酸二氢钾，而单施磷酸二氢钾又优于单施尿素。花生种肥适宜的公顷用量为１５０ｋｇ 磷酸二氢钾＋ ７５ｋｇ 尿素，可使荚果增产１３ ．３ ％ 。
Using potassium dihydrogen phosphate and urea as peanut seedling fertilizer can significantly increase chlorophyll content in peanut seedling leaves, increase leaf thickness and leaf area per plant, and increase photosynthetic capacity of leaves, thus accelerating the accumulation of dry matter in seedlings. Significantly increased the number of peanut fruit can increase the number of fruit and hundred fruit weight, thereby increasing the yield of peanut; strong seedling effect and the rate of increase from the point of view, potassium dihydrogen phosphate and urea with better than the single application of phosphate Hydrogen and potassium, monobasic and potassium monobasic than urea. The suitable amount of hectare for peanut seed fertilizer is 150kg potassium dihydrogen phosphate + 75kg urea, which can increase the yield of pod 13. 3%.
