Effects of Porous Soil Amendments on Soil Properties,Yield and Quality of Flue-cured Tobacco in Bijie
摘要
Abstract
[Objective]It is obvious that use of soil amendments may improve yield and quality of flue-cured tobacco and hence social,economic and ecological benefits considerably.[Method]In order to explore effects of porous soil amendments on soil properties of tobacco fields and yield and quality of flue-cured tobacco in Bijie,a field experiment was conducted and designed to have four treatments,that is,CK(No amendment),T1(straw incorporation),T2(porous soil amendment,T20)and T3(70% T20 and 30% charcoal).[Result]Compared with CK,application of soil amendments increased soil pH by 0.02~0.23, content of total nitrogen,total phosphorus and total potassium by 1.21%~7.27%,1.16%~8.14% and 0.83%~4.44%,respectively,and content of alkalyzable nitrogen,available phosphorus and readily available potassium by 3.39%~15.2%,10.8%~50.9% and 1.78%~37.0%,respectively. In terms of growth of the crop,Treatment T1,T2 and T3 was somewhat higher than CK in plant height,stem diameter,number of effective leaves and leaf area,and in terms of yield and quality of tobacco leaves,they were 3.6%~8.0% higher in yield,3030~4910 yuan hm-2 higher in output value,3.6%~11.7% higher in proportion of upper grade tobacco leaves,and 1.0~1.8 yuan higher in sales price per kilo. Moreover,flue-cured tobacco leaves from the treatments all had nicotine,total nitrogen,reducing sugar,potassium ion and chloride ion in the suitable range for high quality tobacco,and were higher than those from CK in content of total nitrogen, reducing sugar and potassium ion. Obviously,application of the soil amendments may help regulate chemical composition of flue-cured tobacco leaves,including nitrogen/nicotine ratio,sugar/nicotine ratio and sugar/nitrogen ratio,to be reasonable.[Conclusion]Application of suitable soil amendments can effectively improve soil properties and growth and development of the tobacco crop,and yield and quality of flue-cured tobacco in Bijie.关键词
