隆安县玉米生产与地层相关性研究

通过对隆安县玉米种植面积分布较大的１３个地层进行调查，采取地层岩石、土壤和玉米叶样，分别分析其中３１个矿物元素含量，进行地层之间元素含量比较和玉米产量与地层岩石、土壤、玉米叶的营养元素相关性分析，在隆安Ｔ２－３Ｐ１、Ｎ和Ｃ１ｄ为玉米生产优势地层；Ｔ１Ｃ、Ｃ２、Ｄ３Ｔ１ｂ、Ｐ１ｑ、Ｃ１ｙ、Ｃ３和Ｄ２ｄ２为中势地层；Ｐ１ｍ和Ｐ２为劣势地层。发现玉米不但是耐氯力强，而且可能是一种喜氯作物，并有聚氯特点。

A STUDY ON THE RELATIONSHIP BETWEEN CORN PRODUCTION AND STRATA IN LONGAN COUNTY

Upon surveying 13 main strata of corn distribution pattern in Longan County and collecting the samples of rock, soil and corn leaf in which the conteat of 31 mineral elements are analysed. The comparision of elemeat coatents between different strata, the analysis of the relationship between corn yield and mineral element content in rocks, soils and corn leaves are carried out, The result showed that T2-3p1, N and C1d are the superior strata for corn in Longan county. T1l, C2, D3, T1b, P1g, C1y, C3 and D2d2 are the medium strata; P1m and P2 are the inferior ones. we found out that corn is not only a Cl-resistant plant, but also likely to be a Cl-keening plant and it has the peculiarity of accumulating Cl element.
