南雄烟区气候条件与烟叶产量构成及主要化学成分的关系
Effects of climatic conditions on yield components and main chemical constituents of tobacco in Nanxiong, Guangdong Province
摘要
Abstract
Objective]To study effects of climatic factors on yield components and chemical compositions of tobacco in Nanxiong , Guangdong Province .[Method]This research employed data survey , correlation analysis, and regression analysis to study the relationship between main climate factors ( temperature, sunshine and rainfall ) in Nanxiong and tobacco yield components , chemical compositions .[Result]The tobacco leaf yield and its components were mainly affected by rainfall , followed by sunshine hours and temperature .The mass per leaf of the top or bottom leaves and the yield ratio of the bottom and middle leaves were positively correlated with temperature at mature stage , sunshine hour in late May , and rainfall in vigorous growing stage and early April .The amounts of reducing sugar and potassium ions , the ratios of total nitrogen to total nicotine , and reducing sugar to total sugar of the top leaves were significantly cor-related with air temperature and sunshine hour .For the middle leaves , the amounts of total sugar , reducing sugar and potassium ions were significantly positively correlated with sunshine hour;the ratio of total nitrogen to total nicotine was significantly negatively correlated with rainfall in late May;the ratio of reducing sugar to total sugar was significantly positively correlated with rainfall in late March and rainfall in early June.[Conclusion]It is feasible to change the climate conditions in the field of flue-cured tobac-co by adjusting the transplanting time , and thus to regulate the yield components and chemical constitu-ents of tobacco leaves in production .关键词
