摘　　要：模拟了不同类型的酸雨对大棚种植小白菜的喷淋试验。在小白菜的不同生长阶段研究小白菜的3类指标,即生长指标、营养品质指标和生理指标。结果表明,通过对比不同类型酸雨在不同pH下对小白菜的各类指标带来的影响,发现强酸性酸雨对小白菜的生长具明显抑制性,并且抑制营养物质和叶绿素的形成;不同类型的模拟酸雨中,硝酸型酸雨对小白菜的生长抑制作用最大,对营养品质及生理指标的影响也最大。不同类型的酸雨对小白菜的生长生理和营养品质的影响具有差异性。Using the method of simulating acid rain, the effects of different acid rains on the growth, physiological index,and nutritional quality of Brassica chinensis L. were studied. The results showed that the effects of different types of acid rains on the growth, physiological condition, and nutritional quality of B. chinensis were markedly different. The strongly acidic acid rain could inhibit the growth and the formation of nutrients and chlorophyll of B. chinensis Among the different types of acid rains, the nitric acid rain had the most serious influences on the growth, nutritional quality, and the physiological index of B. chinensis.
