Abstract
In some areas of North China,availabilities of minor elements are too low to supply for satisfactory growth of fruit trees because of high pH in soil,which caused some serious disorders in fruit trees.Growers tried to solve these problems by soil fertilizing directly or fertilizing with irrigation water.But these methods had little effect for the nutrient elements were quickly fixed by soil after fertilizing.It took the author five years to compound foliar fertilizers for the fruit trees in these areas.The compound fertilizers content minor elements,a few organic nutrients as well as major elements and the fertilizers have different formulas according to habit of the different kinds of the fruit trees.Chlorophyll contents,nitrate reductase activity,iron content and zinc content in the leaves were significantly increased after 72 h after nectarine trees and grapevines sprayed with fertilizers.The fertilizers could also improve fruit qualities of nectarines and grapes;increase bud weight of grape shoots but had no effect on vigorousness of grapevines.Spayed with the compound fertilizers is beneficial to the trees all the year round,the interval of the sprays being not less than 7 to 10 days.
