Effects of Different Fertilizers on Agronomic,Physical and Chemical Properties of Zhangmulin Small Leaf Tobacco and Daning Tobacco
[Objective]To explore different organic fertilizer application measures suitable for Zhangmulin small leaf tobacco and Daning tobac-co,and provide scientific basis for expanding the planting scale of sun-cured tobacco in Guangxi.[Method]Field experiments were conducted to study the effects of different fertilizer combinations of compound fertilizer,tobacco specific organic fertilizer,and farm manure (tung seed blight,peanut bran,chicken manure,and clay ash) on the growth and physicochemical properties of Zhangmulin small leaf tobacco and Da-ning tobacco.[Result]For Zhangmulin small-leaved tobacco,the growth of tobacco plants in Z2 and Z4 treatments was better,with leaf area reaching 810.58 cm2;Z2 treatment had the largest single leaf weight,and its filling value increased by 29.03％ compared to Z1 treatment;for Zhangmulin small leaf tobacco and Daning tobacco,the content of total sugar and reducing sugar was the best under fertilization treatments of Z2 and Z4,D1 and D4,respectively. Compared to Daning tobacco,Zhangmulin small leaf tobacco were low in nicotine,low in potassium and high in chlorine.[Conclusion]In the application measures of organic fertilizer and compound fertilizer for Zhangmulin small leaf tobacco and Daning tobacco,peanut bran and chicken manure,tung seed blight,chicken manure,and clay ash can be applied to each plant of Zhangmu-lin small leaf tobacco and Daning tobacco to replace tobacco specific organic fertilizer,which is better for the growth and quality of tobacco plants.
