| 摘 要： | 模拟试验结果表明,每公斤红色石灰土中积累水泥厂粉尘在38.0克以下,土壤性状无明显恶化,且对水稻秧苗生长有促进作用。每公斤土壤合粉尘达60.8克时,始见对秧苗生长有不良影响。水泥厂降尘附着于叶面,各种降尘量下秧苗生长均受到不同程度的抑制。

| Abstract: | Results of a model test show the properties of soil was not obviously deteriorated if the dust accumulated in the soil is leSs than 38.0 grams per kilogram red limestone loam, and the growth of rice seedling was beneficially, promoted. Nevertheless, the growth of the crop began to be inhibited when the dust content goes up to 60.8 grams per kilogram soil. The dust which was found adhered to the leaves, no matter how much it was, was harmful to the crop at different degree. |
