本文对华东地区5种不同类型水稻土干土作用的增产效果进行了研究。凡经过干燥处理的水稻士,对水稻的植株高度、有效分蘖数以及单穗重量一般都有良好影响,因此水稻产量均有增加趋势、特别是配施磷、钾肥料,增产尤为显著。从本文试验的结果看来,虽然干土作用与有机质的矿化有很大关系,但土壤pH 值、交换性阳离子及其他矿质营养元素均有影响。磷、钾的关系尤为密切。土壤的干干湿湿是稻田耕作上的一个重要问题。本文讨论了干湿过程对灌水期间各类水稻土的铵态氮素、氧化还原电位、酸度、亚铁离子的影响,指出稻田初灌以后的前期是土壤中生物化学作用最为旺盛的一个时期,而稻田耕作上的干干湿湿,是影响土壤中氧化还原平衡体系的一项有力措施。在水稻栽培期间,这种平衡体系的破坏与建立是促进水稻土有机物的矿化和发挥稻田潜在地力的必要过程。本篇着重讨论了渍水土壤酸度变化的规律及其影响,同时指出土壤酸度变化与发挥水稻土潜在地力的关系。

氯苯类化合物在环境中不易非生物降解,其在环境中的持留性主要决定于微生物降解与否及速率如何。本文用江苏常州大通河灌区土壤实验了这类化合物在厌氧条件的渍水土壤以及好氧条件的湿润土壤中的微生物降解。在此基础上探讨了大通河部分河段底泥中氯苯类化台物含量高的原因,并提出了相应的治理对策。

Dynamics of bound residues of 14C-chlorotoluron, distribution of the bound residues in the components of humus,and their absorption by step-crop (rice) were investigated in paddy soil and black soil under simulated aerobic and anaerobic conditions respectively. The results show that: (1) The bound residues of 14C-chloro-toluron in soil were very considerable and increasing with the incubation time. The organic substance and humidity contained in the soil affected the bound residues remarkably. The bound residues...

Dynamics of bound residues of 14C-chlorotoluron, distribution of the bound residues in the components of humus,and their absorption by step-crop (rice) were investigated in paddy soil and black soil under simulated aerobic and anaerobic conditions respectively. The results show that: (1) The bound residues of 14C-chloro-toluron in soil were very considerable and increasing with the incubation time. The organic substance and humidity contained in the soil affected the bound residues remarkably. The bound residues in black soil with more organic substance and clay particles were higher than those in paddy soil,and under anaerobic conditions were higher than under aerobic conditions. (2) Bound residues of 14C-chlorotoluron mainly bound with the components of soil humus,the distribution of which was in the order of humin >humic acid >fulvic acid. (3) Bound residues of 14C-chloro-toluron in soils could be absorbed by step-crop (rice) and moved to the upper part , that would cause chemical injury, chlorosis and necrosis for the leaf tip.

研究了~(14)C-绿麦隆在模拟渍水和旱地条件下的水稻土和黑土中结合残留、其土壤结合残留物在腐殖质组分间的分布及对后茬水稻的有效性。结果表明:(1)~(14)C-绿麦隆在土壤中具有明显的结合残留,并且它随时间延长而加强;土壤中的有机质和水分的含量对结合残留有明显的影响,就结合残留物来说,有机质和粘粒含量高的黑土高于水稻土;渍水土壤高于旱地土壤;(2)~(14)C-绿麦隆的土壤结合残留物主要集中于腐殖质,其中,结合于胡敏素的>结合于胡敏酸的>结合于富里酸的;(3)~(14)C-绿麦隆在土壤中的结合残留物可被后茬水稻经根系吸收,向上运转,并导致叶尖部受药害而呈现缺绿发枯。
