摘要
本试验以西北黄土高原旱塬山地盛果初期苹果树秦冠为试材，研究了旱期（５～６月）叶面喷施抗蒸剂（抗旱剂１号和丰收宝，有效成分为黄腐酸）对果树生长发育的影响。结果表明：抗蒸剂可使树体主干粗度增加、新梢生长量加大、产量提高，具有明显的经济效益。
Apple trees C. V. Qing-guan of 5～7 years on Rainfed Highland in NorthwestChina were employed in the experiments,The results showed that the anti-transpirants(commercial names: Anti-drought agent No. 1 and Feng Shou Bao,the main effective ingredi-ent is fulvice acid)sprayed on the leaf during drought period could increase the trunk diame-ters, the length of one-year-old stems and the yields. A large profit could be gain from theapplication of anti-transpirants.
