摘　　要：在果树休眠期 ,通过主干注射果树营养液替代果园土壤施肥 ,对苹果外部形态、果实品质及其生理作用影响进行了研究。结果表明 ,萌芽期提前 ,花期早而且盛花期花朵开放整齐稳定 ;萌芽率、成花率、成枝率提高 ;果树根系鲜重和数量显著增加 ,其中 2 0～ 40 cm土层中增长最为显著 ;叶片的光合速率和叶绿素 (a+b)含量也大幅度上升 ;果实品质明显改善 ,产量增加。从总体看 。Effects of the nutrient solution on the morphology and physiology of apple trees and quality of the fruit were studied after the nutrient solution was injected into stems of apple trees in dormant period,results showed that bud sprouting and flowering were early,and blossom at flowering period grow evenly and stably.The ratio of bud sprouting,flowering or shooting was increased.Fresh Weight and number of apple trees root system were significantly increased,especially in 20～40 cm soil depth.The rate of photosynthesis and content of chlorophyll (a+b) were increased by a big margin the apple quality was improved obviously and the yield of apple was also increased in generally,the nutrient solution injected will be widely used and extended for future.
