【摘要】 通过大田随机区组试验研究了10%、20%、30%节肥水平下两种微生物肥料对烤烟生长及产质的影响。结果表明:(1)在团棵期和旺长期,烤烟的农艺性状随着减肥量的增加而降低,在30%节肥水平时,降低较为明显,对烤烟生长的影响较大。到成熟期,金农肥中肥各节肥水平对烤烟的农艺性状均有不同程度地提升,德根贝在10%节肥水平时,烤烟的农艺性状有提升,在20%和30%节肥水平时分别降低10.4%、4.9%。(2)烤烟在3种节肥水平下其经济性状与对照均无显著差异,但不同节肥水平之间存在差异。两种微生物肥料均在20%节肥水平时,烤烟经济性状表现最好。金农肥中肥效果较为明显,显著提高了烤烟上等烟比例、中上等烟比例及均价,且烤烟产值比对照、10%节肥水平、30%节肥水平分别增加12.5%、34.5%、28.2%。更多还原

【Abstract】 The field experiment was conducted to study effects of microbial fertilizer on the growth and quality of flue-cured tobacco in three different chemical fertilizer reduction levels,which is respectively10%、20%、30%reduction level and two kinds of microbial fertilizers were selected in the experiment.Results indicated that:(1)In the rosette stage and the flourishing stage,agronomic traits of flue-cured tobacco overall situation decreased as the amount of chemical fertilizer reduction became larger,while30%reduction level decreased relatively obviously and had a bigger influence on the growth of flue-cured tobacco.In the mature period,increase in different degrees of agronomic traits of flue-cured tobacco were observed from Jinnong Number One application in the all three reduction levels,while Degenbei application only in the 10%reduction level with the others decreased by 10.4%and 4.9%,respectively.(2)Flue-cured tobacco under three chemical fertilizer reduction levels had no significant difference of economic characters from the control,but were there between different chemical fertilizer reduction levels.Both microbial fertilizers under 20%reduction level got the best result of economic characters of flue-cured tobacco.Jinnong Number One performed better,which significantly increased the proportion of tobacco,the proportion of superior and secondary of tobacco and the average price,and the output value increased than control、10%reduction level、30%reduction level by 12.5%、34.5%and 12.5%respectively.更多还原
