摘　　要：合理的留果量是提高果实质量的重要途径。以一窝蜂杏为试验材料,研究不同留果量(果间距3～5 cm、5 cm和10 cm)对杏扁质量(纵径、横径、侧径、单核重、单仁重)及翌年花芽质量(花芽、花瓣和雌蕊重量,雌蕊败育率)的影响。结果表明:疏果处理增大了杏扁果实的纵径、横径和侧径,提高了单核重、单仁重以及翌年花芽、花瓣和雌蕊的重量,降低了雌蕊败育率,但不同处理间均无显著差异;降低了单株产量和经济效益,其中果间距为3～5 cm时与CK差异不显著。认为一窝蜂杏较适宜的留果间距为3～5 cm。Using almond-apricot variety Yiwofeng as the experimental material, the effects of fruiting thinning on the fruit quality and the flower bud quality next year were studied. The spaces between fruits were kept 3 -5 cm, 5 cm and 10 cm, respectively. The results showed that fruit thinning increased the vertical diameter, horizontal diameter, side diameter, single stone weight, single kernel weight, weight of flower bud, petal and pistil, and decreased the pistils sterile rate, while There were no significant differences among different treatments. Fruit thinning decreased the yield per plant and economic benefit. The suitable space between fruits was 3 -5 cm.
