摘　　要：黄红壤上烟草对钾的反应及种烟后土壤钾的变化马友华，李道林，陈邦本，方明（安徽农业大学土化系，合肥２３００３６）（南京农业大学资环系）我国南方亚热带的红壤是我国植烟面积较大的土类，适用于种植各种类型的烟草［１］。烟草是喜钾作物，近年来我国南方在烟草种植...Pot culture experiment with electro-ultrafiltration (EUF) was carried out to study the response of tobacco to K fertilizer and change in soil K after planting tobacco on yellow-red soil. The results showed that the medium rate of K fertilizer could significantly increased yield of cured leaves and coordinated the proportion of sugar to nicotine, thus improving tobacco quality. The values of EUF-K(0-10), EUF-K(10-30) and EUF-K(30-35) decreased by 45%, 25% and 6%, respectively, after planting tobacco without K application.The intensity, quantity and potentiality of soil potassium increased obviously after planting tobacco with K application. There were delayed effects of K ferilizer on yello-red soil.
