合成洗涤剂（LAS）对农作物影响的研究

Study of the Effect of the Synthetic Detergent(LAS)on Crops.

本文采用水培和盆栽试验的方法，研究合成洗涤剂（ＬＡＳ）对小麦、水稻的幼苗、生育期、产量、质量以及黄瓜、萝卜的苗期影响。探讨ＬＡＳ对农作物危害的临界浓度和合理使用污水灌溉农田ＬＡＳ的允许浓度范围。

he effects of the synthetic detergent LAS on the seedling ,the growth,the yield and the quality of wheat,rice,cucumber,or radish were investi-gated under both water cultivation and pot experiment.The critical con-centrations of LAS to various crops were determined and the acceptable concentrations of LAS in wastewater irrigation were proposed.
