버어리종 담배의 염소에 관한 연구 III. 석회, 인, 철, 망간 및 붕소시용이 담배의 염소흡수 및 이화학성에 미치는 영향

STUDIES ON THE CHLORINE OF BURLEY TOBACCO PLANTS III. THE EFFECTS OF LIME, PHOSPHORUS, IRON, MANGANESE AND BORON ON CHLORINE ABSORPTION, CHEMICAL CONSTITUENTS AND PHYSICAL PROPERTIES OF LEAF TOBACCO

Effects of some mineral nutrients on the chlorine absorption by the plants, on the chemical constituents and physical properties of leaves were investigated tinder the paddy field and pot conditions. The chlorine content of cured leaf grown in paddy field was high in iron and manganese application groups and highest in combined application of iron and manganese. Lime application inhibited the absorption of chlorine and increased the yield and quality of cured leaf, and inhibited the absorption of iron and manganese those causing the grey leaf. Lime application reduced the leaf chlorine content and rate of muddy grey leaf by increasing the soil pH in acid soil.
