不同浓度乙烯利对核桃温185适时采收的影响

Effect of Different Concentrations of Ethephon on Timely Harvest of Walnut Wen 185

于核桃采收前10 d,分别使用不同浓度的乙烯利对核桃树进行全树喷施,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。结果表明:喷施350 mg/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%,较除对照外的其他浓度处理均低。由此表明,喷施350 mg/L乙烯利可显著促进温185核桃果实青皮开裂,且对叶片边缘黄化影响较小。

10 days before the walnut harvest,different concentrations of ethephon were used to spray the whole walnut trees to analyze the effects of different concentrations of ethephon on the fruit green peel cracking rate and yellow leaf rate.The results showed that on the 7th day after spraying 350 mg/L ethephon,the fruit green peel cracking rate was 75.59%,which was 57.94%higher than that of the control;the yellow leaf rate was 18.06%,which was lower than that of other concentration treatments except the control.Therefore,spraying 350 mg/L ethephon can significantly promote the fruit green peel cracking rate of walnut Wen 185,but has little effect on leaf edge yellowing.
