烤烟育苗是烤烟生产中的重要环节,培育壮苗是获得高产优质的首要关键。根据烟农的经验,要想育出无病、适龄、整齐、粗壮,栽后成活率高,生长旺盛,无早花现象的烟苗,必须施足基肥,但究竟“足”的限量如何?基肥施足多少方能满足烟草苗期营养要求,尚缺乏试验研究。又据山东益都、临朐等烟区重点社队的调查,烟农施肥数量各地多少不一,悬殊甚大,并有多数烟农主张不施磷钾肥料。由此看来,烟草苗期基肥施用实为生产上急待解决的一个问题,必须进一步探讨。为此,我们曾做下述试验,旨在寻求基肥最足施用量和配合磷钾肥料的增产效益,为经济、合理、有效的施用基肥和培育壮苗提供科学依据,以便指导生产。
Flue-cured tobacco seedling production is an important part of flue-cured tobacco production, nurturing strong seedlings is the primary key to high yield and quality. According to the experience of tobacco farmers, in order to bring out disease-free, age-appropriate, tidy, sturdy, high survival rate after planting, vigorous growth, no premature flower phenomenon, must apply Shizujifei, but after all, How much enough to meet the nutritional requirements of tobacco seedling stage, the lack of experimental study. According to a survey of key commune and brigade groups in the tobacco areas of Yidu and Linqu in Shandong Province, the number of tobacco farmers is varying from place to place, with great disparities. Most farmers and farmers advocate no application of phosphorus and potassium fertilizers. Seen in this light, the base fertilizer application at seedling stage is actually a problem to be solved urgently in production and must be further explored. To this end, we have done the following test, aimed at seeking the most adequate amount of basal fertilizer and phosphorus and potassium fertilizer with the yield-generating benefits for the economic, reasonable and effective base fertilizer and nurturing seedlings provide a scientific basis to guide the production.
