测定了华中丘陵地区主要成土母质发育的红壤中的微量元素含量,成土母质为花岗岩、石灰岩、千枚岩、第三纪红砂岩和紫砂岩、第四纪红色粘土。土壤标本包括红壤旱地、未垦地和水稻土,全部为剖面标本。分析结果说明红壤中微量元素含量和可给性与成土母质有密切关系。全硼含量以石灰岩发育的红壤为最多,花岗岩发育的最少。有效态硼除个别土壤以外,都低于缺硼临界值,其中以花岗岩母质发育的红壤为最突出。在我国南方(例如福建、广东和江西南部)花岗岩分布得相当广泛,土壤中硼的供给情况值得注意,硼肥可能获得良好的反应。全钼含量则以花岗岩发育的红壤为最高,砂岩发育的最低。砂岩和石灰岩发育的红壤中有效态钼含量最低,常低于缺钼临界值。红色粘土发育的红壤中有效态钼虽然较多,但豆科植物对钼肥仍然表现了良好的反应,这意味着在钼的供给情况更差的其他土壤上,钼肥的预期效果可能也是很好的。红色粘土和砂岩发育的红壤中有效态锌一般都低于缺锌临界值,一些树木上存在着缺锌症状。水稻土中的有效态锌常低于临界值。红砂岩发育的红壤中的有效态铜也很少,常低于缺铜临界值。田间试验证实了水稻对硼肥的反应良好。在施用石灰的条件下,以硼肥浸种使水稻生长茁壮、根系特别发达、千粒重增加、空瘪率降低,产量也有所增加,返青与成熟期提前。温室试验证实,硼肥的效果与石灰施用水平有关。硼肥和钼肥都能使大豆和花生的产量提高。含硼工业废渣是廉价的硼肥肥源。 The content of trace elements in the red soils mainly derived from parent material and parent material in the central hilly region of China was determined. The parent materials are granite, limestone, phyllite, Tertiary red sandstone and purple sandstone, and Quaternary red clay. Soil samples include red soil dry land, uncultivated land and paddy soil, all for the section specimens. The results showed that the contents and availability of trace elements in red soils are closely related to the parent materials. Full boron content to limestone development of red soil is the most, granite development of the least. The available boron was lower than the critical boron deficiency except for some soils, of which red soil with granite parental material was the most prominent. Granites in southern China (eg Fujian, Guangdong and southern Jiangxi) are widely distributed. The supply of boron in the soil is noteworthy, and boron fertilizers may achieve a good response. Total molybdenum content is the highest in red granite development, the lowest sandstone development. The available molybdenum content in the red soils developed in sandstone and limestone is the lowest, which is often lower than the critical value for molybdenum deficiency. Although there are more available molybdenum in red clay with red clay development, leguminous plants still show a good response to molybdenum fertilizer, which means that the expected effect of molybdenum fertilizer may be very good in other soils where the supply of molybdenum is worse Ok. The available zinc in red soils with red clay and sandstone development is generally below the threshold for zinc deficiency and some trees have zinc deficiency symptoms. The available zinc in paddy soil is often below the critical value. Red sand red sandstone in the active state of copper is also very small, often less than the lack of copper critical value. Field experiments confirmed that rice responded well to boron fertilizers. Under the condition of applying lime, the soaking of boron fertilizers made the rice grow robustly, the root system developed especially, the grain weight increased, the empty flat rate decreased, the yield also increased, the greening and the maturity advance. Greenhouse test confirmed that the effect of boron fertilizer and the level of lime application. Both boron and molybdenum fertilizers increase soybean and peanut yields. Boron industrial waste is a cheap boron fertilizer source.
