不同施肥方式对烤烟膜下小苗移栽的影响

摘要

In order to study the effects to transplanting tobacco under different fertilization methods that seedling beneath the plastic film, we used Yunyan 87 as the material to conduct a field test, compared the transplanting survival rate, growth period, agronomic traits, economic traits and other aspect. The result shows that the middle layer surrounding fertilization is the most beneficial to the growth and yield of tobacco. Pond fertilization has an effect on the survival rate, and fractional fertilization is complicated and laborious. Banding fertilization is the worst, and the effective utilization rate of fertilizer is low. Middle layer surrounding fertilization is suggested.%为研究不同施肥方式对烤烟膜下小苗移栽的生长及产量影响,以烤烟品种云烟87为材料进行大田试验,分别对移栽成活率、生育期、农艺性状、经济性状等方面进行比较.结果表明:中层环施最有利于烤烟生长和产量提高;拌塘施对移栽成活率有影响,分次施肥操作复杂且费力、费工;条施最差,肥料的有效利用率低.建议采用的施肥方式是中层环施.
