Study on the Optimal Sweet Potato Cutting Periods with Flue-cured Tobacco Intercropping in Qiandongnan Prefecture
摘要
Abstract
Objective] The aim was to improve soil of tobacco fields, solve flue-cured tobacco continuous cropping obstacle, improve use effi-ciency and land productivity, increase farmers’ income.[Method] Through carrying out flue-cured tobacco-sweet potato intercropping experi-ment, effects of time on yield and quality of flue-cured tobacco were studied.[ Result] The results showed that the productivity of sweet potato cuttings after 25 d of flue-cured tobacco transplanting is higher than other processing unit area yield, and the net income is 118 316 yuan/hm2 . [ Conclusion] Sweet potato cuttings after 25 d of flue-cured tobacco transplanting is more suitable for intercropping tobacco and can obtain a higher income, the implementation of tobacco interplanting sweet potato, not only increase multiple cropping index, but also effectively pro-mote the balanced development of flue-cured tobacco and other crops.关键词
