【摘要】 研究表明 :不同浓度酸雨对小麦株高、结实率、穗粒数、千粒重、生物产量及经济产量的影响都达到极显著水平 ,对穗长的影响达显著水平 ,而公顷穗数各处理间差异不显著。不同酸雨处理间生物量积累存在差异 ,pH值越低 ,生物量积累越慢 ;pH值越高 ,生物量积累越快更多还原

【Abstract】 The effect of simulated acid rain on later stage biological and economic yield of wheat in the late stage was studied. The result indicated the biological and economic yield of wheat had differences(P<0.01) in the different amount of acid rain.更多还原
