以果树防冻营养剂为试材,选取甘肃、陕西和山西3个苹果产区果园为研究对象,以果树防冻营养剂涂抹“富士”苹果树干后,分别对“富士”苹果叶片矿质元素含量、新梢生长量、果实品质进行了测量分析,以探究果树生物药剂对果树生长状况的影响。结果表明:涂抹果树防冻营养剂后能够提高叶片中全氮、全钾、镁和锰的含量;新梢长、单果重增加;能够提高果实中可溶性固形物、总糖、花色苷的含量,对果树生长及果实品质有显著提高的作用。
Taking fruit tree antifreeze nutrient as test material, three orchards of apple orchards in Gansu, Shaanxi and Shanxi were selected as research objects. After applying “Fuji” apple tree trunks with fruit tree antifreeze nutrients, the effects of “Fuji” apple leaf mineral Element content, shoot growth, fruit quality were measured to explore the fruit tree biological agents on the growth of fruit trees. The results showed that the content of total nitrogen, total potassium, magnesium and manganese in leaves could be increased after application of fruit tree antifreeze nutrients; the length of shoots increased and the weight of fruit increased; the content of soluble solids, total sugar and anthocyanin in fruits could be increased; Fruit tree growth and fruit quality significantly improve the role.
