摘    要:探讨乙烯利对‘温185’核桃果实青皮开裂度和叶片黄叶率的影响,为适时机械化采摘核桃提供参考依据。于核桃采收前10天分别使用不同浓度的乙烯利对核桃树进行全树喷施,测定核桃青皮开裂率、黄叶率指标,分析不同浓度的乙烯利对核桃果实青皮开裂率和黄叶率的影响。在喷施浓度为350mg/L乙烯利后第7天,果实青皮开裂率为75.59%,较对照高出57.94%,叶片黄叶率为18.06%,较对照高出11.57%。乙烯利喷施浓度为350 mg/L可显著促进‘温185’核桃果实青皮开裂,而对叶片边缘黄化影响较小。

关 键 词:‘温185’核桃  乙烯利  适时采收  青皮开裂率  叶片黄化率

The Effect of Different Concentrations of Ethephon on the Timely Harvest of"Wen 185" Walnut
Abstract:To explore the effects of ethephon on the cracking degree of the green peel of the"Wen 185" walnut fruit and the yellow leaf rate of the leaves, and to provide a reference for timely mechanized picking of walnuts. 10 days before the walnut harvest, different concentrations of ethephon were used to spray the whole tree on walnut trees to determine the cracking rate of walnut green peel and yellow leaf rate, and analyze the effect of different concentrations of ethephon on the cracking rate and yellow leaf rate of walnut fruit. Impact. On the 7th day after spraying 350mg/L ethephon, the fruit green peel cracking rate was 75.59%, which was 57.94% higher than the control, and the yellow leaf rate was 18.06%, which was 11.57% higher than the control. Spraying ethephon at a concentration of 350 mg/L can significantly promote the cracking of the green peel of"Wen 185" walnut fruit, but has little effect on leaf edge yellowing.
