[目的]为我国南方低纬高海拔烟区烤烟间套种生产实践提供理论依据。[方法]通过大田小区试验,研究烤烟与不同豆科作物套作的农业生物多样性种植措施对烤烟烟叶生长发育与产质量的影响。[结果]各处理对烤烟生育期、农艺性状、田间自然发病率和烤后烟叶外观质量的影响不大,且处理之间不存在显著差异,但处理B(红花大金元与四季豆套作)的产量、产值高于其他处理。从3种不同豆科作物与烤烟套作的投入与产出比值来看,处理B和处理C(红花大金元与黄豆套作)经济效益较好,且处理B最好,中、上等烟比例较单作分别提高了4.48和3.15个百分点,产值增加10 865.25元/hm2,即投入最低,产值最高。[结论]红花大金元与四季豆套作可提高烟农收入和土地利用率。
[Objective] The research aimed to provide a theoretical basis for the production practice of flue-cured tobacco intercropping in low latitude and high latitude areas in southern China. [Method] The experiment of field plot experiment was conducted to study the effects of planting measures of agricultural biodiversity on the growth, yield and quality of flue-cured tobacco leaves with flue-cured tobacco and different leguminous crops. [Result] The treatments had little effect on the growth period, agronomic traits, natural incidence in the field and appearance quality of flue-cured tobacco after treatment, and there was no significant difference between treatments. However, the treatments B For production), the output value is higher than other treatments. In terms of the ratio of inputs and outputs of three different leguminous crops and flue-cured tobacco sleeves, the economic benefits of treatment B and treatment C (safflower Daikin and soybean sets) were better, and treatment B was the best, middle and upper The proportion of isobaric cigarettes increased by 4.48 and 3.15 percentage points respectively compared with that of single crop, and the output value increased by 10 865.25 yuan / hm2, that is, the lowest investment and the highest output value. [Conclusion] The planting of safflower Daikin and Sidi bean could increase the income and land utilization of tobacco growers.
