烟叶喷施稀土微肥,是一项开发性新技术。1985年,省农科院烟草研究所在方城县余庄村作了不同浓度的小区试验和大面积示范,供试和示范品种均为9140,效果都很显著。小区试验设0.02％、0.04％、0.06％、0.08％四个浓度处理,各在烟叶旺长至现蕾期喷施三次。喷清水对照。三次重复,分别有张敬国等三家科技户承担。收烤结束,上等烟比例依前述处理浓度顺序,分别达到17.44％、21.2％、22.84％、26.34％,与对照(14.94％)相比,分别提高16.73％、42.3％、52.88％,76.31％;亩收益依次达到417.27元、431.87元、450.55元和451.35

Rare-earth tobacco leaf fertilizer, is a development of new technologies. In 1985, the Provincial Academy of Agricultural Science Tobacco Research Institute in Fangcheng County Village made different concentrations of community experiments and large-scale demonstration, test and demonstration varieties are 9140, the effect is significant. Community trial set 0.02%, 0.04%, 0.06%, 0.08% of the four concentrations of treatment, each in the leaf to the budding bloom time spraying three times. Spray water control. Three repetitions, respectively, Zhang Jingguo and other three science and technology households commitment. At the end of roasting, the proportion of top-grade tobacco increased by 16.73%, 42.3%, 52.88% and 76.31%, respectively, by 17.44%, 21.2%, 22.84% and 26.34% respectively compared with the control (14.94% ; Mu income in turn reached 417.27 yuan, 431.87 yuan, 450.55 yuan and 451.35
