针对天水早春气温波动大 ,寒潮、大风天气多 ,低温冷害重而育苗成活率低的气候背景 ,1996～ 1998年对烤烟育苗期间 ,进行适宜气象条件及最佳育苗设施的对比试验研究 ,得出当地烤烟幼苗健壮生长的最适环境气象条件。同时 ,也得出了当地烤烟育苗的最佳设施是双膜纸钵大畦与弓棚大畦 ,以双膜纸钵大畦最佳
In view of the climatic background of the high temperature fluctuation in early spring in Tianshui, cold weather, windy weather and heavy chilling damage, the survival rate of seedling was low. From 1996 to 1998, comparative experiments on suitable meteorological conditions and best seedling establishment during flue-cured tobacco seedling raising were conducted. The optimum environment and weather conditions for robust growth of local flue-cured tobacco seedlings. At the same time, it also concludes that the best facilities for cultivating local flue-cured tobacco are the double-membrane pots and the large-scallops,
