“丰收宝”对小麦种子萌发和幼苗生长有明显的促进作用。经浸种处理后,加快发芽速度,提高种子活力。萌发种子的α-淀粉酶活性和呼吸速率均显著高于对照。对幼苗根系的促进作用大于对地上部的促进,提高幼苗的根系活力。小麦不同生育时期叶面喷施“丰收宝”的生理效应主要表现为增加叶片的叶绿素含量和光合速率,促进硝酸还原酶活性,提高叶片可溶性蛋白质和籽粒蛋白质含量。各处理以起身期、拔节期和灌浆期施用效果明显。 “Harvest treasure” on wheat seed germination and seedling growth has a significant role in promoting. After soaking seed treatment, accelerate the speed of germination and improve seed vigor. The α-amylase activity and respiration rate of germinating seeds were significantly higher than that of the control. Roots of seedlings to promote greater than the role of the ground to promote and enhance the root activity of seedlings. Physiological effects of foliar fertilization at different growth stages of wheat mainly include increasing chlorophyll content and photosynthetic rate, promoting nitrate reductase activity, and increasing leaf soluble protein and grain protein content. All treatments were effective at beginning stage, jointing stage and filling stage.
