The invention belongs to the technical field of
salix integra cultivation, and particularly relates to a
fertilizer applying method for improving
salix integra toughness. The method includes the steps: applying 1100-1200kg of
microorganism organic fertilizers into soil of planting land per mu before
cutting of
salix integra; spraying
nutrient solution 8-10 days after cuttage and
sprouting of the salix integra, spraying the
nutrient solution once every 18-20 days, and continuously spraying the
nutrient solution for three times. The
microorganism organic fertilizers are applied before cuttage,
nutrition needed for
plant growth is provided, growth of salix integra root systems is facilitated, ability of the salix integra root systems absorbing nutrients is improved, salix integra bodies are smooth, diseases and
insect pests are effectively prevented and treated,
soil acidification and soil hardening are effectively restrained, continuous updating ability of the salix integra is enhanced, the
nutrient solution is continuously sprayed after
sprouting,
cell activity of salix integra branches is effectively enhanced, branching and
branch growing ability of the salix integra is enhanced,
cellulose synthesis is facilitated, the
toughness of the salix integra is effectively improved, and
toughness keeping capacity is effectively improved.
