【摘要】 以厌氧发酵残余物沼液、化肥及沼液+化肥3种肥料作为根施追肥,辅之以不同叶面喷施沼液次数,研究不同施肥种类,肥料量及叶面喷施次数的不同水平组合对红富士苹果品质及叶片生理效应的影响。结果表明,叶面喷施次数达到6次时,叶绿素相对含量最高,平均达到55.59,高出对照3.319%。当单施沼液时,光合速率平均值达到16.622μmol.cm-2.s-1,高出对照26.029%。在高水平肥料量条件下,硬度平均达到7.504 kg.cm-2,高出对照22.454%;在中水平施肥条件下,还原糖18.175 mg.g-1,高出对照3.905%。更多还原

【Abstract】 The effect of different combinations of fertilizer type,fertilizer amount and times of biogas slurry sprayed on leaves on quality of Fuji apple and physiological activity of Fuji have been studied.In the precondition of equivalent N,P(P2O5),K(K2O),fertilizer type : biogas slurry,chemical fertilizer,the mixed fertilizer of biogas slurry and chemical fertilizer.And fertilizer amount : high level,middle level,low level.Spraying times: 2,4,6.The experimental results showed that: four spraying times can increase chlorophyll relative contents with 55.59,improving 3.319% by CK.And by applying biogas slurry,photosynthesis rates is 16.622 μmol·cm-2·s-1,improving 26.029% by CK.In the case of high level of fertilizer account,hardness of fruit is 7.504 kg·cm-2,and reduced sugar 18.175 mg·g1,improving 22.454%,3.905% by CK,respectively.更多还原
