铜基营养保护剂对苹果生长及果实品质的影响

Effects of Copper-Based Nutrition Protective Powder on Apple Growth and Fruit Quality

以铜基营养保护剂(CBN1)、含铁铜基营养保护剂(CBN2)、含硼锌铜基营养保护剂(CBN3)为试材,与传统波尔多液进行大田对比试验,研究了3种铜基营养保护剂(CBN)对苹果生长和果实品质的影响。结果表明:较之传统波尔多液(CBM),3种铜基营养保护剂的防病效果与其相当且没有造成果实减产及品质降低,但显著降低了铜在叶片和果实中的含量。含铁铜基营养保护剂(CBN2)和含硼锌铜基营养保护剂(CBN3)分别在果树不同生育时期及时供给植株所需的铁和锌,同时增加果实中铁和锌的含量。因此,依据果树生长发育时期不同,配合使用不同的铜基营养保护剂可以有效的替代传统波尔多液。

With copper base nutrition protective agent（CBN1）,iron-copper base nutrition protective agent （CBN2）, boronzinc-copper base nutrition protective agent（CBN3）as materials,the effects of CBN on apple fruit quality were investigated by field experiment on apple tree compared to conventional Bordeaux Mixture （CBM）. The results showed that CBN had the same disease resisting ability with CBM,and did not make the yield and quality reduce. Copper content in leaves and fruit was significantly reduced by CBN. Moreover,copper-based nutrition protective powder with iron （CBN2） ,with boron and zinc （CBN3） supplied iron and zinc during different growth stages,and the contents of iron and zinc in fruit were also increase＆ Overall,CBN could replace CBM effectively during all the growth stages of apple tree.
