烟叶的质量受土壤条件、品种、栽培技术、气候和烘烤技术等多种因素影响,而土壤条件中的土壤酸度是影响土壤养分转化及其有效性的决定因素之一。本试验采用田间调查与室内研究相结合的方法,采用“YH调酸材料”调节植烟根际土壤pH,解决植烟根际土壤中pH过高对烤烟的产量和产值存在的不利影响,有效的改善土壤的结构状况,使土壤肥料因素得到改善,协调烟株养分吸收,促进烟株正常生长发育;随之显著提高烤烟的产质量和降低碱性植烟根际土壤中的pH的目的。
The quality of tobacco leaves is affected by many factors such as soil conditions, varieties, cultivation techniques, climate and baking techniques. Soil acidity in soil conditions is one of the determinants of soil nutrient conversion and its effectiveness. In this study, the method of field investigation and indoor research were combined to adjust the rhizosphere soil pH by using “YH acid-adjusting material” to solve the problem that the high pH in tobacco rhizosphere soil has an adverse effect on the yield and output value of flue-cured tobacco , So as to effectively improve the structure of the soil, improve the factors of soil fertilizers, coordinate the absorption of tobacco nutrients and promote the normal growth and development of tobacco plants, and significantly increase the yield and quality of flue-cured tobacco and reduce the pH in rhizosphere soil of alkaline tobacco plants purpose.
