烟草的农学性能和化学成分受到遗传和环境两种因素的影响。特殊的品种有其特异的基因型。品种的实际表现则是由它们基因型和生育期间诸如灌溉、施肥等不同栽培措施所决定的。据以往资料,随着氮素率的增加,白肋烟的产量,价值,总氮和总植物碱量增加。四个白肋烟品种在施氮肥率从112公斤/公顷增加到179公斤/公顷时,调制烟叶的产量增加,总氮量随着氮素率的增加持续地增长,而
The agronomic properties and chemical composition of tobacco are affected by both genetic and environmental factors. Special varieties have their own specific genotypes. The actual performance of breeds is determined by their genotypes and different cultivation measures such as irrigation and fertilization during their birth. According to past data, the yield, value, total nitrogen and total alkaloid content of burley tobacco increased with the increase of nitrogen rate. Four Burley varieties increased their N-fertilizer production from 112 kg / ha to 179 kg / ha, while the total nitrogen increased steadily with the increase of N rates
