【摘要】：以河南省不同烤烟种植区为条件,研究了施用微生物肥对土壤微生物数量、烟叶经济产量及化学品质的影响及其相关性。结果表明:4种微生物肥均在一定程度上增加了根际土及非根际土中细菌、真菌及放线菌的数量,并且提高了烤烟的经济产量及化学品质。豫南雨养烟区(SR)微生物肥C对烟叶产量和产值增幅最多,分别比对照提高28.92%、51.95%,微生物肥A对提高上部烟叶钾含量效果最佳,比对照提高47.10%;豫西旱作烟区(WD)微生物肥D对烟叶产量和产值增幅效果最佳,分别比对照提高12.43%、23.49%,微生物肥C对下部烟叶钾含量提高最为显著,比对照增加55.68%。土壤微生物数量与烟叶产量及化学品质间具有一定相关性,豫南雨养烟区(SR)细菌与钾呈极显著正相关,真菌与烟碱呈极显著正相关,与氯呈极显著负相关;豫西旱作烟区(WD)细菌与烟叶产量、产值、氯含量之间呈显著正相关,与烟碱含量呈显著负相关。总之,受气候等生态条件影响,建议豫南雨养烟区(SR)示范应用微生物肥C,豫西旱作烟区(WD)示范应用微生物肥D。
[Abstract]:Using different flue-cured tobacco growing areas in Henan Province as the condition, the effect of applying microbial fertilizer on soil microbial quantity was studied. The effect of economic yield and chemical quality of tobacco leaves and their correlation. The results showed that the microbe fertilizer increased the number of bacteria, fungi and actinomycetes in rhizosphere soil and non-rhizosphere soil to some extent. And the economic yield and chemical quality of flue-cured tobacco were improved. The microbial fertilizer C increased the yield and output value of tobacco leaves the most, 28.92% and 51.95% higher than that of the control, respectively. Microbial fertilizer A had the best effect on increasing potassium content in upper tobacco leaves. The microbial fertilizer D had the best effect on the increase of yield and output value of tobacco leaf, which was 12.433.49g higher than that of the control, and the microbial fertilizer C had the most significant effect on the increase of potassium content in the lower part of tobacco leaf. There was a significant positive correlation between soil microbial quantity and tobacco yield and chemical quality. There was a very significant positive correlation between bacteria and potassium, fungi and nicotine, and a significant negative correlation with chlorine. WD) bacteria were positively correlated with tobacco yield, output value and chlorine content, and negatively correlated with nicotine content. In short, they were affected by climate and other ecological conditions. It is suggested that the application of microbial fertilizer C should be demonstrated in the rain and tobacco cultivation area in south Henan, and the microbial fertilizer D should be demonstrated in the dry growing tobacco area in the west of Henan Province.
