摘要
掌握土壤养分肥力,是制定施肥策略的基础。本研究采集了广西壮族自治区荔枝主产区果园土壤样本185个,福建省荔枝主产区果园土壤样本25个,分析了土壤有机质和N、P、K、Ca、Mg、S、Cu、Zn、B、Mo含量,评价荔枝果园土壤养分肥力现状。结果显示:广西和福建两省荔枝果园土壤有机质、碱解氮、速效钾、有效钙、有效镁、有效硼、有效钼含量均为低水平,广西荔枝果园有效磷和有效锌为中下,福建为中上,有效铜中等,有效硫含量较高。整体上两省荔枝园土壤养分肥力较低且不平衡。不同荔枝主产区土壤养分肥力状况差别很大,硼是广西荔枝园土壤最普遍缺乏的元素,镁、钼次之。而镁是福建荔枝园土壤最普遍缺乏的元素,硼、钙次之。
Knowing the soil nutrient fertility is the basis to formulate a suitable fertilization strategy. One hundred and eighty five samples in litchi orchards in the Guangxi Zhuang automomous region and twenty five samples in litchi orchards in Fujian province were collected, and organic matter, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, copper, zinc, boron and molybdenum level were analyzed. Soil nutrient fertility status in the litchi orchards was investigated. The result showed that the soil organic matter, alkaline nitrogen, available potassium, available calcium, available magnesium, available boron and available molybdenum were low both in Guangx^i and Fujian. The available phosphorus and available zinc were at middle/low level in Cuangxi while middle/high level in Fujian. The available copper was middle and available sulfur was higher. Generally, soil nutrient fertility in Litchi plantation of Guangxi and Fujian was lower with imbalance. The status of soil nutrient fertility difference was great in different Litchi plantation. In Guangxi, boron was the scarcest element in Litchi plantation soil, magnesium and molybdenum took second place. In Fujian, magnesium was the scarcest element in Litchi plantation soil, boron and calcium took second place.
