摘　　要：以富士苹果树为材料,研究了不同剂量稻壳炭施加以及稻壳炭配施复合肥和有机肥引起的苹果树叶片净光合速率、蒸腾速率、叶绿素含量、叶片厚度、叶片重量、叶面积和春梢长度的春夏季生理和生长指标变化。研究结果表明,苹果树施加稻壳炭2.50 kg/株可以明显增加叶绿素含量、降低蒸腾、促进光合作用,为苹果树的最佳施加量;稻壳炭配施复合肥可以有效地降低蒸腾作用,防止春梢枝条徒长;稻壳炭配施有机肥可以有效地提高叶绿素a含量,提高净光合速率。The effect of rice husk char and adding rice husk char to compound fertilizer and organic fertilizer on net photosynthetic rate,transpiration rate,chlorophyll contents,the thickness,weight,area of leaves,and the length of spring twig of Malus Domestica Fuji tree were studied.The study results showed that adding 2.50 kg rice husk char to each tree was the best amount with high chlorophyll contents,reduction of transpiration rate and high efficiency of photosynthesis.The reduction of transpiration rate and shorten spring twigs were found when adding rice husk char to compound fertilizer. And the high chlorophyll a contents and high efficiency of photosynthesis were found when adding rice husk char and organic fertilizer.
