摘要 [目的]利用芝麻餅及牛糞作為基質(zhì),將解鉀菌接種于2種基質(zhì)上發(fā)酵、干燥制成菌肥,研究芝麻餅及牛糞基質(zhì)的解鉀菌菌肥對(duì)煙草生長、pH和TDS值的影響。[方法]在煙草移栽后和團(tuán)棵期進(jìn)行施肥處理,并記錄農(nóng)藝性狀、pH和TDS值的變化。[結(jié)果] 在團(tuán)棵期,芝麻餅及牛糞基質(zhì)處理能夠促進(jìn)下層側(cè)根的生長,可能增加煙株的根系體積;株高和煙葉的數(shù)量增加比較明顯,而最大煙葉的面積和莖圍增加較小;芝麻餅及牛糞基質(zhì)處理與對(duì)照根、莖、葉的pH相比差異不顯著;2個(gè)處理與對(duì)照均為莖部的TDS值最大;在團(tuán)棵期到打頂期,對(duì)照和處理的根部pH均偏向中性,下部莖與根部pH相比,均呈酸性;對(duì)照和處理的根部TDS值相差明顯,對(duì)照的根部TDS值最大,下部莖、中部莖和上部莖的TDS值明顯小于根系,下部葉和中部葉的TDS值又小于下部莖和中部莖。[結(jié)論]該研究結(jié)果可為芝麻餅和牛糞為基質(zhì)的生物肥及菌肥提供基礎(chǔ)數(shù)據(jù),為該生物肥的推廣和應(yīng)用提供依據(jù)。

Abstract [Objective] Sesame cake and cow dung were used as the substrate in this study, and potassium-free bacteria were inoculated on two substrates to ferment and dry into bacterial fertilizer in order to study effects of potassium bacteria fertilizer on growth,pH and TDS of tobacco. [Method] Fertilization treatment was carried out after tobacco transplanting and at the cluster stage, and the changes of agronomic traits, pH and TDS values were recorded. [Result] Sesame cake and cow dung substrate could increase root volume, especially lower lateral root growth, increase plant height and tobacco leaf quantity, however, the area and stem circumference of the largest tobacco leaf increased less, the pH value of sesame cake and cow dung substrate was not significantly different from the control root, stem and leaf, the TDS value of both treatments and control was the largest, and the pH value of control and treatment was neutral from the bottom to the top stage. The TDS values of the control and treatment roots were significantly different, the TDS values of the control roots were the largest, the TDS values of the lower stem, the middle stem and the upper stem were significantly smaller than those of the root system, and the TDS values of the lower and middle leaves were also smaller than those of the lower and middle stems. [Conclusion] The results can provide basic data for bio-fertilizer and bio-fertilizer based on sesame cake and cow dung, and provide basis for the popularization and application of bio-fertilizer.

3 結(jié)論
芝麻餅及牛糞基質(zhì)處理在團(tuán)棵期,能夠增加煙草植株的根系體積,特別是下層側(cè)根的生長比較旺盛,為后期植株的快速生長提供了堅(jiān)實(shí)的物質(zhì)基礎(chǔ)。在團(tuán)棵期之前,株高和煙葉的數(shù)量增加比較明顯,而最大煙葉的面積和莖圍增加較小。在團(tuán)棵期之前,芝麻餅及牛糞基質(zhì)處理與對(duì)照根、莖、葉的pH相比差異不顯著;在團(tuán)棵期到打頂期對(duì)照和4個(gè)處理的根部pH均偏向中性,下部莖與根部pH相比,均呈酸性;中部莖與下部莖相比,CK、T3和T4處理偏中性,而T1和T2處理更加偏酸性。團(tuán)棵期之前,2個(gè)處理與對(duì)照均為莖部的TDS值最大;團(tuán)棵期到打頂期,對(duì)照和4個(gè)處理的根部TDS值相差明顯,對(duì)照的根部TDS值最大,下部莖、中部莖和上部莖的TDS值明顯小于根系;下部葉和中部葉的TDS值又小于下部莖和中部莖。
