猕猴桃不同果园土壤和叶片营养状况分析

以"金魁"猕猴桃为试材,分析了湖北宜昌雷家畈地区高中低产园及藤肿病园土壤和叶片营养状况,结果发现,高产园叶片Ca含量比其它果园高10%～17%,叶片Ca为影响猕猴桃产量的关键性因素,叶片Ca含量高则果园整体产量高;藤肿病发生严重的果园土壤有效Cu的含量为0.93 mg/kg,极显著低于其他果园;当地猕猴桃园土壤交换性Ca含量207.8～306.0 mg/kg,有效Fe含量1.98～3.00 mg/kg,处于缺乏状态;P和Cl元素含量丰富。土壤和叶片之间矿质元素有不同程度的相关,其中土壤与叶片之间Cl元素相关性极显著。

Nutrient diagnosis of leaves and soil at kiwifruit orchards with different yields

For investigating feasible nutrient index on producing high quality fruit and instructing right fertilizing in kiwifruit,nutrition status of soil and leaf was analyzed in different yieldJinkuikiwifruit orchards,such as high yielding,middle yielding,low yielding and much dead trees in Leijiafan,Yichang District.Results showed as following:there was higher from 10% to 17% about Ca content in leaves of high yielding orchard than other orchards,the content of Ca in the leaves was the main element which influenc...
