基于猕猴桃叶片黄化问题的土壤分析研究

Soil Analysis Based on the Problem of Kiwifruit Leaf Chlorosis

随着种植面积的扩大,叶片黄化成为猕猴桃生长中常见的现象,严重影响猕猴桃生产的效益。选取陕西省周至县正常和发生叶片黄化的猕猴桃果园各6个,取样并测定了果园土壤的pH和养分含量。结果表明,发生叶片黄化的猕猴桃果园中土壤的pH平均偏高0.99,土壤中有机质的含量是正常果园的32.3%,且中微量元素匮乏。通过对土壤中各养分之间的相关性分析,提出采取调节土壤的pH、增施有机肥和中微量元素等措施,来改善猕猴桃果树叶片黄化的状况,以提高猕猴桃的产量和品质。

With the expansion of planting area,leaf chlorosis has become a common phenomenon in kiwifruit growth,which seriously affects the benefits of kiwifruit production.Six kiwifruit orchards each with normal situation and occurring leaf chlorosis situation are selected in Zhouzhi County,Shaanxi Province,and the pH and nutrient content of the orchard soil are sampled and determined.The results show that the pH of the soil in the kiwifruit orchards where leaf chlorosis occurred is 0.99 higher on average,and the content of organic matter in the soil is 32.3%of that in the normal orchards,and medium and trace elements are scarce.By analyzing the correlation between the nutrients in the soil,measures such as adjusting the pH of the soil,increasing the application of organic fertilizers and medium and trace elements to improve the leaf chlorosis of kiwifruit fruit trees and the yield and quality of kiwifruit are proposed.
