Abstract

Comparison experiments were made in Fu County of Shanxi Province for apple trees fertilized with biogas residue on roots and biogas slurry on leaves in different ratios.The results indicated that: basic fertilization on root with 35~40 kg of biogas residue and 4~5 times of leave spraying with biogas slurry in concentration of 50%~70% were favorable for each individual apple plant during the growing period,which could turn the apple leaves into dark green,the average area of single leaf increased by 22.28%,branche thickness increased by 42.9%,and the trees are vigorous.The flowering rate raised 16.4%,and the defoliation rate decreased by 31.21%.In additional,the aphids and red spider killing rates were 78.3% and 82.3% respectively.the fruit output increased by 12.2%.
