Luo Jianxin

Abstract

The effects of high molecular weight polymer for tobacco(HMWPT) on growth,yield and quality of flue-cured tobacco were investigated in the Northwestern Hunan.The best result was observed with treatment of 4.5 g HMWPT per plant.HMWPT application improved tobacco root growth,increased effective leaf number and stem width,increased leaf yield 15.4% and output value 3 345 yuan/hm2,increased soil capability of conserving water and nutrients,and soil nutrient availability as well.
