摘要：为了对北票市晚秋蜜桃种植中采收前落果情况进行改善、提高其抗寒能力，特开展了不同处理方式下晚秋蜜桃落果情况及抗寒能力效果研究，结果表明，试验中采取的6种保果措施均可降低晚秋蜜桃采收前的落果率，其中落果率较未采取措施的对照处理增幅超过60%的处理有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;不同的方式均可提高晚秋蜜桃的抗寒能力，其中受凍率较对照降低80%以上的处理有对树干的基部进行包草+喷施天达2116、对树干的基部进行包草+培土这2个处理。由此可知，在晚秋蜜桃的种植中，可采取修剪细长枝条、疏花疏果、喷施天达2116、树干包草等措施，对减少采收前落果率、降低受冻率有明显的效果。

Abstract： In order to improve the fruit drop before harvest in the late autumn peach planting in Beipiao City， and improve its cold resistance， a study on the late autumn peach fruit falling and the cold resistance effect under different treatment methods was carried out. The results show that the test is in progress. The six fruit-preserving measures adopted can all reduce the fruit-drop rate of late autumn peaches before harvest. Among them， the fruit-drop rate is increased by more than 60% compared with the control without measures. The treatment includes pruning the slender branches + spraying Tianda 2116， appropriate The two treatments of thinning flowers and fruit + spraying Tianda 2116; different methods can improve the cold resistance of late autumn peaches， 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. Carry out the two treatments of wrapping grass + cultivating soil on the base of the trunk. It can be seen that in the planting of late autumn peaches， measures such as pruning slender branches， thinning flowers and fruits， spraying Tianda 2116， and tree trunks and grasses can be used to reduce the fruit drop rate before harvest and reduce the freezing rate. .

桃在我国栽培历史悠久，是一种口感佳、营养价值高的水果，受到各年龄段消费者的青睐[1]。桃树在山区、半山区或者一些贫瘠的土壤上种植比较多，近些年随着各地农业种植结构的调整，桃种植快速发展起来，越来越多优良的桃品种选育出来并在适生区域内得到了广泛的推广种植[1]。晚秋蜜桃属于柏山水蜜桃芽变的晚熟桃新品种，具有很强的抗寒能力，适合在北票市等气候干旱、寒冷的区域进行栽植，每年成熟的时间为10月1日前后，此时正处于市场上鲜桃的空档期，可取得更好的经济效益，此外，晚秋蜜桃成熟后可在树上挂果15d以上，室温下也可储藏10d，具有很强的耐储运能力[2]。……
