钾虽然不是植物组织的主要组成部分,但它与植物许多酶的活性有关,对碳水化合物的代谢、细胞水分的调节以及蛋白质、氨基酸的合成有重要作用。因此,桃园土壤中缺乏钾素会严重影响桃树的正常生长发育和增产增收。桃树对钾的吸收量较氮多,比磷更多。整个树体在一年内氮、磷、钾的吸收比例为10:4:13。对盛果期大树,施钾的作用更大。据测定,施钾量和氮量
Although potassium is not a major component of plant tissue, it is related to the activity of many enzymes in plants and plays an important role in the metabolism of carbohydrates, the regulation of cell moisture and the synthesis of proteins and amino acids. Therefore, the lack of potassium in Taoyuan soil will seriously affect the normal growth and development of peach tree and increase income. Peach on potassium absorption more than nitrogen, more than phosphorus. The whole tree in a year of nitrogen, phosphorus and potassium absorption ratio of 10: 4: 13. On the full-fruit trees, the role of potassium more. According to determination, the amount of potassium and nitrogen
