长效有机肥与烟草专用肥配施对烟草产量和品质的影响

化肥在提高农业单位面积产量的同时造成了一定的环境污染,长效有机肥的可以在一定程度上解决化肥所造成的环境压力,同时可以提高农业作物的产量和品质。本研究采用长效有机肥与烟草专用肥配施,探究不同肥料配施比例对烟草产量和品质的影响。结果表明,腐殖酸肥与烟草专用肥配合施用,能够增强烟株对气候斑病和赤星病等病害的抗病性,提高烟叶的均价、上等烟比例和上中等烟比例,促进烟叶总植物碱、氧化钾等含量的增加,降低还原糖等含量,化学成分更协调,外观质量和感官质量等有所提高,减少用工量和肥料投入,降低总投入,提高产投比,但同时表现出从移栽到团颗期的生长发育较缓慢。

Effects of long-lasting organic fertilizers with special tobacco fertilizers on tobacco yield and quality

Chemical fertilizers have caused some environmental pollution while increasing the yield per unit area of agriculture, and long-lasting organic fertilizers can solve the environmental pressure caused by chemical fertilizers to a certain extent, and at the same time can improve the yield and quality of agricultural crops. In this study, we used long-lasting organic fertilizers and special tobacco fertilizers to investigate the effects of different fertilizer ratios on the yield and quality of tobacco. The results show that humic acid fertilizer and special tobacco fertilizer can enhance the resistance of tobacco plants to diseases such as climatic spot disease and red star disease, increase the average price of tobacco, the proportion of top-grade tobacco and the proportion of top-medium tobacco, promote the increase of total phytobasic alkali, potassium oxide and other contents of tobacco, reduce the content of reducing sugars and other contents, the chemical composition is more coordinated, and the quality of appearance and organoleptic quality has been improved, reduce the amount of labor and fertilizer input, reduce the total input, improve the production ratio, but the quality of tobacco can not be improved. inputs, and improve the production/input ratio, but at the same time showed slower growth and development from transplanting to dough stage.
