为了解土壤中有效铜含量,我们曾对我区部分县社164个样品进行了分析。从结果看出土壤有效铜平均含量为4.9ppm,远高于缺铜临界值(1.9ppm)。但仍有26%的样品低于临界值的,主要分布于河池、钦州、百色等耕作水平较低的地方。在各种土壤中,熟化的泥肉田、潮泥田有效铜含量较高,分别为7.0ppm,5.4ppm,丘陵红壤、铁子田(土)含量很低,分别为1.8ppm、2.2ppm,紫泥田、棕泥田含量也不高,分别为2.8ppm、2.9ppm。这与耕作管理水平
In order to understand the effective copper content in soil, we have conducted 164 samples of some counties in our district. The results show that the average soil available copper is 4.9ppm, much higher than the critical copper deficiency (1.9ppm). However, there are still 26% of the samples below the critical value, mainly distributed in Hechi, Qinzhou, Baise and other low tillage areas. In all kinds of soils, the available copper content in matured muddy fields and tidal mud fields were higher, which were 7.0ppm, 5.4ppm, hilly red soil and low iron soil (soil) respectively, which were 1.8ppm, 2.2ppm, purple Soil, brown clay content is not high, respectively, 2.8ppm, 2.9ppm. This is the level of farming management
