论文不同冬种绿肥对皖南烟区烤烟产质量影响是适合不知如何写绿肥方面的相关专业大学硕士和本科毕业论文以及关于绿肥种植论文开题报告范文和相关职称论文写作参考文献资料下载。
摘 要：为了筛选提升皖南烟区烤烟产质量的冬种绿肥品种,设置植烟土壤原位种植绿肥作物紫云英、黄花苜蓿和冬牧70,测定绿肥掩青前生物学性状及元素成分,探讨各绿肥处理烤烟烟叶的农艺性状、经济性状、化学成分及感官评价.结果显示,第3年绿肥干物质量以冬牧70最高为1.97 t/hm2,分别是紫云英和黄花苜蓿的2.46倍和7.30倍.紫云英和冬牧70处理的烤烟最大腰叶面积显著高于对照和黄花苜蓿.冬牧70和紫云英处理的烤烟产量分别提高了9.67%和3.53%,产值分别提高17.59%和10.75%.冬牧70处理的上部烟化学成分协调性和感官评价均优于黄花苜蓿和紫云英处理.综合评价认为,绿肥冬牧70可以作为皖南烟区优质冬种绿肥品种.

Abstract： In order to screen for varieties of green manure in Southern Anhui tobacco areas to promote the tobacco yield and quality, Astragalus sinicus, Medicago falcata and Secal ecerale were planted in tobacco planting soils. Biological traits and main chemical components of green manures were measured before ploughed under the soil. The tobacco agronomic traits, main chemical component, yield and the quality from different green manure treatments were analyzed. The results showed that the yield of dry grass of Secal ecerale was the highest, being 1.97 t/ha, 2.46 and 7.30 times of that of Astragalus sinicus and Medicago falcate respectively. The maximum area of waist leaves of Astragalus sinicus and Secal ecerale treatments were significantly higher than CK and Medicago falcate. The tobacco leaf yield of Medicago falcate and Astragalus sinicus treatments were increased by 9.67% and 3.53%, and economic values were increased by 17.59% and 10.75%, repectively. The harmony of chemical composition of top leaves from the Secal ecerale treatment was better than that from Medicago falcate and Astragalus sinicus. The smoking quality of top leaves from different treatments displayed the same trend. In conclusion, Secal ecerale can be considered as the alternative green manure in Southern Anhui tobacco areas.
