Abstract
Effects of soil come from different preceding crops on tobacco growth,root activity,the nitrate reductase(NR) activity and chemical composition of tobacco leaf were studied by pot experiment.The results showed that growth of tobacco was evidently promoted and the cooperatively of chemical composition in tobacco leaves was clearly improved by soil came from rice and rapeseed.Promoting effect on growth of tobacco of soil came from tobacco was unclear,and its chemical composition of tobacco leaf became worse.Soil came from maize clearly inhibited the growth of tobacco,and produced harmful effect on cooperatively of chemical composition in tobacco leaves.
