摘 要:通过对照试验,分析了沼肥对果树长势、苹果品质和土壤肥效的影响。结果表明,应用沼液进行根施和叶面喷施,可增加果树新梢长度和枝条径粗,果树总产量增加13%~20%,果实口感好,营养丰富。施用沼肥可改善土壤理化性质,氮、磷、钾处于丰富的水平,有机质处于中等至稍丰的水平。In comparison with those trees fertilizer, the effects of biogas residues on the growth of apple trees and the fruit nutrient quality and the soil fertility were determined and analyzed. The results showed that the new tresses were longer and thicker than the contrast ones, and the yield of apple trees was increased by 13%-20%. The apples were delicious and nutrimental. The physical and chemical characters of soil were improved. N, P and K element in the soil were very abundant, while the organic substance was of medium level.
