摘要
果树不结果或少结果的主要原因有果树的开花结果特性差异、营养生长和生殖生长失调、小年树现象、外界因素影响、实生树处于童期等。针对果树结果不良的原因提出了相应的防治措施。
Fruit trees produce no or fewer fruits mainly because the trees have different flowering and fruiting characters, imbalanced vegetative growth and reproductive growth, off-year phenomenon, unfavorable external factors,and young seedling plants. In view of specific causes, this paper proposed corresponding prevention measures.
