摘要
【目的】研究饼肥添加有机质对重茬烤烟养分吸收和及品质的影响,为重茬烟区合理施用有机肥提供科学依据。【方法】在田间条件下,设置不施肥对照(B1)、常规施肥(B2)、大豆饼肥添加有机质(B3)3个处理,B2、B3处理养分用量为N52.50kg/ha,P2O578.75kg/ha,K2O105.00kg/ha;测定不同时期烤烟干物质及养分含量。【结果】移栽后第13周,B3处理干物质积累量为3909.49kg/ha,比B2处理提高26.76%,两者差异达显著水平;B3处理总氮、总磷、总钾积累量分别为86.12、8.98、79.17kg/ha,与B2处理相比分别提高36.22%、17.54%、12.06%;B3处理产量比B2处理提高13.68%,上等烟比例提高4.44%,产值提高14.83%,达到50539.65元/ha。【结论】施用添加有机质(600.00kg/ha)的大豆饼肥(300.00kg/ha)可使烤烟氮积累量显著提高,并降低烤烟重茬障碍。
[Objective ]The present study was conducted to assess the impacts of organic cake fertilizer on the nutrient absorption and output of continuous cropping flue-cured tobacco, provide reference for reasonal in order to application of organic fertilizers in tobacco planting areas. [Method ]The content of dry matter and nutrient content of flue-cured tobacco was measured at varying period under three treatments of tile control（B1 ）,conventional fertilization （B2）and organic fer- mented soybean cake with B2 and B3 having the nutrient amount of 52.50 kg/ha N,78.75 kg/ha P205 and 105.00 kg/ha Kg）. [Result]In the 13th weeks after transplanted, the accumulative dry matter of B3 was 3909.49 kg/ha with 26.76% significant increase of B2. The accumulative content of total nitrogen, phosphorus, potassimn in B3 was 86.12,8.98 and 79.17 kg/ha, which was 36.22%, 17.54% and 12.06%, respectively higher than B2 treatment. Compared to B2, the yieht of B3 was up 13.68%, top tobacco up 4.44%. With 14.83% more output, the output of B3 reached ￥50539.65. [ Conclusion ] It is con- cluded that 300.00 kg/ha fermented soybean cake accompanied by 600.00 kg/ha organic matter remarkably boosted the accumulative nitrogen content in flue-cured tobacco and reduced the barriers of continuous cropping flue-cured tobacco.
