Study On Cultivation Model Of Navel Orange Interplanting Flue-cured Tobacco

Aiming at a new planting mode that the cultivation techniques is unclear of navel oranges interplanting Flu-cured tobacco, connected with the local actual, the experiments were respectively done at 2008-2009 in million Mu demonstration base of the navel oranges in the west of Yi Zhang County, Chen Zhou, to research the effects of production,quality of flu-cured tobacco as well as physicochemical properties of soil from different navel oranges interplanting Flu-cured tobacco density and different biogas manure amount,the results showed that:Although the production of flu-cured tobacco in the model of single ridge,single plant,2 ridges between the navel oranges lines was decreased,the improve of the interplanting density was conducive to the growth of tobacco groups, individual growth and development even more coordination, and in the harvest time, the tobacco leaves can normally mature and turn yellow, the leaf was thinner, density was lesser, organization structure was more soft, chemical composition at a suitable level and even more coordination. Under different fertilization, the tobacco individual in each treatment was sufficient grow, groups grow coordination, and were similar to the regular production of flue-cured tobacco. The tobacco planted in the mode of 20% biogas manure+80% chemical fertilizer growing well in the field, appearance was more better, and leaf was slightly thinner, single-leaf weight was medium, leaf density decreased, the organizational structure was more soft, chemical composition was coordination, output value was the highest one.
