- 摘要:
- 在长期定位定点试验条件下, 设置5 个处理研究易涝地稻田水盐的变化规律。研究结果表明, 不同时期各处理水盐运动有比较一致的变化趋势。由于地表积水的变化, 泡田后井灌区、渠灌区、井渠结合区的土壤含盐量均比泡田前分别降低了0 .008 %、0 .007 %和0 .021 %。井灌条件下, 老稻区土壤全盐量及各离子含量均高于新稻区。渠灌条件下, 老稻区土壤全盐量及各离子含量也均高于新稻区, 全盐量分别高了0 .025 %和0 .008 %。这说明随着种稻年限的增加有发生次生盐渍化的可能。
- Abstract:
- Under conditions of f ixed place trail for a long time , the change of w ater and salt in rice field of humid land w as studied w ith five t reatments .The result show ed that the change of w ater and salt in different periods and treatments w as in relatively identical regularities.The salt w as lower before soaking field than af ter soaking field .In both w ell irrigation and channel irrig ation , the total content of salts and content of ions were all hig her in old rice plot than in new rice plot .
