不同生物质炭施用量对汉中烤烟生长发育、产量产值和品质的影响

摘要

Field plot experiment were arranged to study the effects of biomass carbon dose on tobacco agronomic traits, yield and output value and conventional chemical composition in different growth periods of tobacco from May to September of 2014 in Moziqiao town,Yang county, Hanzhong city, Shaanxi province.The results showed that the application of biomass carbon could promote the growth and development of flue-cured tobacco and improve the quality of tobacco.In rosette stage and prosperous, on the basis of conventional fertilization increased 3000 kg/hm2 , flue-cured tobacco of the agronomic traits compared to other treat-ment were good, and in mature period, on the basis of conventional fertilization increased 1500 kg/hm2 , the general growth of the flue-cured tobacco as compared to other treatment were good; increased 2250 kg/hm2 on the basis of conventional fertilization, flue-cured tobacco yield, the output value, the fine tobacco ratio and the proportion of the central smoke reached the maximum.%2014年5～9月，在陕西省汉中市洋县磨子桥镇布置田间小区试验，研究了不同用量的生物质炭条施对烟叶各生育时期农艺性状、烤后烟叶产量产值和常规化学成分的影响。结果表明，施用生物质炭可以促进烤烟的生长发育和提高烟叶质量；在烤烟生长的团棵期和旺长期，在常规施肥的基础上增施3000 kg／hm2时，烤烟的各项农艺性状指标较其他处理好；而在烤烟生长的成熟期，在常规施肥的基础上增施1500 kg／hm2时，烤烟的总体长势较其他处理好；在常规施肥的基础上增施2250 kg／hm2时，烤烟的产量、产值、上等烟比例、中部烟比例均达到最大值。
