摘　　要：为了对晚秋蜜桃采收前落果情况进行改善,提高其抗寒能力,开展了不同处理方式对晚秋蜜桃落果情况及抗寒能力影响的研究,结果表明:6种保果措施均可降低晚秋蜜桃采收前的落果率,与未采取措施的对照相比,对细长的枝条进行修剪+喷施天达2116、适当疏花疏果+喷施天达2116这2个处理落果率可减少60%以上;不同的处理方式均可提高晚秋蜜桃的抗寒能力,其中树干基部包草+喷施天达2116、对树干基部包草+培土这2个处理,受冻率较对照降低17.7个百分点以上。在晚秋蜜桃的种植中,采取修剪细长枝条、疏花疏果、喷施天达2116、树干包草等措施,可减少采收前落果率、降低受冻率,效果显著。In order to improve the fruit drop on Amygdalus persica before harvest in the late autumn planting in Beipiao City,and improve its cold resistance,a study on Amygdalus persica fruit falling and the cold resistance effect under different treatment methods was conducted.Result shows that the six fruit-preserving measures all can reduce the fruit-drop rate of Amygdalus persica before harvest.Compared with the CK without measures,the fruit-drop rate can be reduced by more than 60%by adopting twotreatm ents.(Pruning the slender branches+spraying‘Tianda’2116 on Amygdalus persica,appropriate treatments of thinning flowers and fruit+spraying‘Tianda’2116 on Amygdalus persica);different methods can improve the cold resistance of Amygdalus persica,and the treatment that reduces the freezing rate by more than 80%compared with the control includes wrapping grass on the base of the tree trunk+spraying‘Tianda’2116 on Amygdalus persica,wrapping grass on the base of the trunk.The freezing rate is 17.7 percentage points lower than the control.It can be seen that in the planting of Amygdalus persica,measures such as pruning slender branches,thinning flowers and fruits,spraying Amygdalus persica‘Tianda’2116,and tree trunks and grasses can be used to reduce the fruit drop rate before harvest and reduce the freezing rate.
