     Results obtained showed that puddling of clayey paddy soil, especially, of the soil with poor structure was beneficial to rice growth under pot experimental condition of no leaching: but the advantage of puddling disappeared under field condition.
     其结果表明:土壤粘闭对水稻生长的影响与水位和渗漏等因素密切相关,在淹水不渗漏的盆钵条件下,粘闭土壤对水稻生长的效果优于团聚土壤,特别是对于粘质黄泥土更是如此。 但是这种优势在田间自然条件下,由于渗漏以及其它因素的参与,又可能被模糊。
短句来源
     It was found that prolonged submergence could achieve higher contents of water dispersible silt and clay before and after puddling, but the lowering of soil strength and the forming of effective puddling layer were affected by puddling implements in the experiment rather than by submergence time.

The clay mineral and chemical composition of clay fraction, morphologic al feactures, physical and chemical properties, as well as cation exchangeproperties of three soil profiles collected from Wuhan were studied. The soil formingconditions and genesis process were also discussed. In terms of the differencesof mineral and chemical composition of clay fraction, morphological features, basesaturation and other physical or chemical properties among examined soils, accordingto the principle of comoining soil forming conditions, soil forming process and soilproperties, we consider that soils derived from the pleistocene deposit distributingon the undulating hill and soils developed from devonian sandstone distributing onthe hill are yellow brown earth and red earth respectively.

本研究分析了武汉市三种类型土壤的形成条件、剖面形态特征,并测定了粘粒部分的矿物组成与化学组成,土壤的交换吸附特性,以及一般物理、化学性质。测定结果表明石质丘陵泥盆纪砂岩残积物、坡积物上发育的土壤,粘粒部分以高岭石、水云母为主,有一定量的14A过渡矿物,少量的蛭石。平缓丘陵地晚更新统粘土母质(Q_3)上发育的土壤,粘粒部分以水云母、蛭石、高岭石为主,少量14埃过渡矿物。近代河流沉积物上发育的土壤,粘粒部分以水云母为主,其次为蛭石与高岭石,有少量蒙皂石和绿泥石。它们的硅铁铝率相应地为小于2,2.1-2.2,2.4-2.5;pH值、盐基饱和度分别依次为4.62-4.98、5.43-5.97、7.05-7.60和16.50-35.97%、52-94%、接近100%。近代河流沉积物上发育的灰潮土的粘化现象不明显,晚更新统粘土母质上发育的土壤表层下有粘化层,志留纪砂岩残积、坡积物上发育的土壤粘化层更为明显;其粉砂粒与粘粒含量比之比值,塑性指数与粘粒的物理活性相应地依次减小,同样地表明它们的发育程度不同。所以,根据土壤形成条件、形成过程和土壤属性相结合的分类原则,考虑到武汉市地处中亚热带与北亚热带之间的过渡地带...

Results of semi quantitative study on composition of clay minerals of vertisols and vertic fluvants showed that contents of smectite, hydromice and kaolinite in clay fractions of vertisols collected from Huaihe River Plain were 41.1%~56.5% 23.5%~39.4% and 14.9%~20.5%, respectively. Contents of these clay minerals in clay fractions of vertic fluvants collected from lower Yangtze Plain were 20.7%~29.0%,43.6%~51.0% and 20.0%~35.7A%, respectively.

Contents of these clay minerals in clay fractions of vertic fluvants collected from lower Yangtze Plain were 20.7%~29.0%,43.6%~51.0% and 20.0%~35.7A%, respectively. Verticulite was present in all soil samples, while chlorite was only found in silt fractions of all soils under study. The diagnostic character for identification of vertisols is addressed and soil classification at family levels is suggested in this paper.

对淮北变性土和长江下游变性型新成土的粘土矿物半定量研究表明,变性土胶粒和粘拉以蒙皂石占优势,粘料中蒙皂石占41.1%~56.5%,次为水化云母、高岭石。新成土胶拉以蒙皂石为多,粘粒则以水化云母为主,占43.6%~51.0%,次为高岭石,尚存蒙皂石及混层矿物。二地区土壤粘拉中含蛭石,但均未发现绿泥石。粉砂中矿物类型甚多,但几无蒙皂石。作者认为大量膨胀性粘土矿物存在,是土壤产生变性诊断特征的物质基础,因而是变性土鉴定主要依据之一。文中对上述土壤作了土属的系统分类和命名。
