不同生物質炭施用量對大理烤煙生長發(fā)育和質量的影響?

　　摘要 [目的]研究不同生物質炭施用量對烤煙的生長發(fā)育及烤后質量的影響。[方法]采用田間小區(qū)試驗對不同生物質炭施用量下的生育期中部煙葉的農藝性狀及烤后煙葉的外觀質量、經濟學性狀、評吸質量進行比較分析。[結果]施用生物質炭可顯著提高煙葉團棵期及旺長期的農藝性狀與成熟期的葉片數、最大葉面積。生物質炭施用量為3.75 t/hm2時，團棵期煙葉的農藝性狀最佳；生物質炭施用量為4.50 t/hm2時，旺長期與成熟期煙葉的農藝性狀最佳。施用生物質炭的烤后煙葉外觀質量、經濟學性狀均顯著高于常規(guī)施肥，評吸質量均高于常規(guī)施肥。生物質炭施用量控制在4.50 t/hm2時，烤后煙葉的質量最佳。[結論]施用生物質炭是促進煙葉的生長發(fā)育并改善其品質的有效措施，其最佳施用量為4.50 t/hm2。

　　Abstract [Objective] To study the effects of different application doses of biomass charcoal on the growth and quality of fluecured tobacco.[Method] Field experiment was carried out to research the effects of different application doses of biomass charcoal on the agronomic characters of middle leaves at growth period，as well as on the appearance quality，economic traits and smoking quality of fluecured tobacco.[Result] The application of biomass charcoal could significantly improve the agronomic characters at rosette stage and vigorous growing stage，the leaf number and the maximum leaf area at mature stage.When the application dose of biomass charcoal was 3.75 t/hm2，the agronomic characters of tobacco leaf were the best at rosette stage.When the application dose of biomass charcoal was 4.50 t/hm2，the agronomic characters were the best at vigorous growing stage and mature stage.The appearance quality and economic characters of fluecured tobacco under the application of biomass charcoal were significantly higher than those under conventional fertilization.Smoking quality under the application of biomass charcoal was higher than that under conventional fertilization.When the the application dose of biomass charcoal was 4.50 t/hm2，the quality of tobacco leaves was the best.[Conclusion] Application of biomass charcoal is an effective measure to promote the growth and quality of tobacco leaves.And the best application dose of biomass charcoal is 4.50 t/hm2.

　　近年來，云南煙區(qū)由于連作重茬現象嚴重[1]，導致土壤肥力下降，土壤保肥性能較低，病蟲害加重，烤后煙葉質量降低，嚴重影響了當地煙農的經濟效益和煙葉的工業(yè)利用率。生物質炭是一種含碳豐富的固體物質，由生物質在低于700 ℃的高溫下熱解制成[2]。目前，生物質炭應用于大豆、玉米、小麥等作物的研究較多[3-5]，結果顯示生物質炭可以改善土壤的理化性質，提高土壤肥力，并改善或提高植物品質。
