采用小区试验,开展了苕子、紫云英、箭舌豌豆、燕麦等4种绿肥翻压处理对烤烟的生长发育及产、质量影响的研究。结果表明:与对照相比,4种绿肥翻压不同程度地促进了烟株生长发育,较明显地提高了烟叶上等烟的比例,促进烟叶产量、产值的增加;其中苕子翻压对改善烤烟农艺性状最明显,而箭舌豌豆翻压对提高上等烟比例最突出。这说明绿肥翻压能较明显地提高烟叶上等烟的比例,改善烟叶的内在品质,增加产值,从而提高烟叶的经济效益。
Community trials were carried out to study the effects of four green manure treatments, such as Chinese buckwheat, Astragalus mollis, arrow tongue pea and oat, on the growth, yield and quality of flue-cured tobacco. The results showed that: compared with the control, four kinds of green manure pressors promoted the growth and development of tobacco plants to different degrees, obviously increased the proportion of superior tobacco and promoted the increase of output and output value of tobacco; The most obvious agronomic traits of flue-cured tobacco, while the arrow tongue pea pressure on the promotion of the highest proportion of the most prominent tobacco. This shows that the pressure of green manure can obviously increase the proportion of superior tobacco, improve the intrinsic quality of tobacco and increase the output value, so as to improve the economic benefits of tobacco.
