不同产量、品质的赤霞珠葡萄园叶柄、土壤养分状况调查分析

为提高酿酒葡萄产量、品质和合理施肥提供依据，对河北省昌黎县不同产量、品质的赤霞珠葡萄园的叶柄、土壤养分状况进行了调查分析。结果表明，中、低产低质葡萄树体K、Zn含量较低，树体Mg缺乏是3种园区都存在的问题，低产低质园树体Fe含量明显偏低；中、低产低质葡萄园土壤有机质、水解N、有效P、K、Zn较低，3种园区土壤交换性Mg含量均较低。高产优质园，土壤N、K、Mg与叶柄相应元素之间为正相关，中产低质园，土壤N、K、P、Mg、Zn与叶柄相应元素之间为正相关，低产低质园，土壤K、Mg、Zn与叶柄相应元素之间为正相关。

Leafstalk Analysis and Soil Nutritional Diagnosis of Cabernet Sauvignon Grape Cultivar in Chang Li County of HeiBei Province

To provide basis for increasing yield, quality and optimizing fertilization for Cabernet Sauvignon of different yields and quality levels in Changli County of Hebei Province, leafstalk analysis and soil nutritional diagnosis were carried out. The results showed that K, Zn contents of Cabernet Sauvignon plant were low in the orchard of middle and low yield and low quality, and the problem of Mg deficiency existed in all these three orchards, Fe content was obviously low in low yield and quality orchard. In the orchard of middle and low yield and low quality, soil O.M., avail N,.P, K, and Zn were low, and avail. Mg in the three types of orchard were relatively low. In the orchard of high yield and good quality, soil avail. N, K and Mg were of positive relation with relative elements in the leafstalks, in the orchard of middle yield and low quality, soil avail. N, K, P, Mg and Zn were of positive relation with relative elements in the leafstalks, while in the orchard of low yield and low level, soil avail. K, Mg, and Zn were of positive relation with relative elements in the leafstalks.
