| 摘 要： | 对湖北省柑橘主产区143个柑橘园0～30cm的土壤样品进行了测试分析。结果表明,全省有89.5%柑橘园土壤pH值适合柑橘生长;有59.4%的柑橘园土壤有机质含量偏低,土壤速效N、P、K缺乏分别为78.3%、44.1%和77.6%;中量元素养分Ca、Mg缺乏分别为39.1%和37.1%;分别有34.3%、20.3%、16.8%、63.6%、35.5%和77.4%的柑橘园缺乏有效Fe、Mn、Cu、Zn、Mo和B。土壤有效Ca、Mg、Fe、Mn、Cu、Mo含量在部分柑橘园存在过量现象,分别占柑橘园的9.8%、4.9%、7.7%、4.9%、3.5%和4.0%。柑橘园土壤pH值、有机质和各种有效养分含量呈现一定的地域性变化,如鄂南柑橘园土壤偏酸,而汉江流域(鄂北)土壤偏碱;鄂南Ca和Mg缺乏程度高,汉江流域含量相对较高,而有效Fe、Mn、Zn含量则相反。调查结果还表明,柑橘园土壤有效Cu和B含量受人为活动的影响非常明显。

| Abstract: | Top soil(0～30cm)samples from 143 citrus groves in Hubei Province were tested and classified. The results showed that the soil pH in 89.5% orchards was suitable for citrus growth, and soil organic matter (OM) in 59.4% orchards was in low status, and the deficiency rate of available macro nutrients N, P and K was 78.3%, 44.1% and 77.6%, available second nutrients Ca and Mg was 39.1% and 37.1%, and micro nutrients Fe, Mn, Cu, Zn, B and Mo was 34.3%, 20.3%, 16.8%, 63.6%, 35.5% and 77.4%, respectively. The result also indicated that soil available Ca, Mg, Fe, Mn, Cu and Mo exceed percentage was in excess in 9.8%, 4.9%, 7.7%, 4.9%, 3.5% and 4.0%, respectively,of the citrus gardens in the province. The study revealed that the soil pH, OM and available nutrients changed with the citrus location distribution. For example, soil pH in the province southern production area was lower than that along Hanjiang river area (in north of Hubei), and Ca and Mg of orchard soil in the south was much lower than that in north, while the Fe, Mn and Zn was on the contrary. |
