树体自动滴输微肥对果树生理和果实品质的影响

研究了树体自动滴输技术在苹果树、核桃树及柿树上的应用．结果表明：通过输施微肥可以促进树体营养生长和发育，提高核桃树花粉生活力及坐果率．节果树经输施后，果实着色显著增加，微量元素含量显著提高，铁(Fe)、锌(Zn)元素可分别比对照提高13．28％～22．90％、42．54％～43．22％，处理果实中硒(Se)及锗(Ge)的增幅较大，分别是对照的9．545倍及4．7173倍．该技术是提高我国果树生产力和改善苹果营养价值的有效方法．图1表7参18

EFFECTS OF DRIPPING INJECTION OF MICROELEMENTS ON FRUIT TREE PHYSIOLOGY AND FRUIT QUALITY

The effects of automatic dripping injection technique on apple, walnut and persimmon were studied. The results showed that the application was easy and no power was required. After fruit trees were injected with microelements, the vegetative growth and development of the trees were promoted, and the pollen vitality of walnut was improved. By injecting apple trees with microelements, the fruit coloration, the microelement contents of the trees and their fruit were increased significantly. The contents of Fe and Zn in apple on treated trees were increased by 13. 28%-22. 90% and 42. 54%-43. 22% , respectively. The Se and Ge concentrations of apple on treated trees were 9. 545 times and 4. 717 3 times higher than those of control trees. The study indicates that the dripping injection technique is a valuable method that could promote fruit trees'productivity and improve nutrition value of apple. Fig 1, Tab 7, Ref 18
